AC Breaker Keeps Tripping Breaker: 9 Common Culprits & Fixes

“My AC keeps tripping the breaker. What’s wrong? How do I stop my AC from tripping the breaker?”

AC tripping the breaker is annoying. Even more troublesome, repeatedly trying to run an air conditioner that keeps tripping the breaker can result in permanent damage to the AC unit. So, easy on the breaker reset button ; you should diagnose and fix the problem first.

ac keeps tripping breaker

Here is what might be happening with your air conditioner:

  • Air conditioner trips the breaker immediately . When you turn the AC unit, the breaker will flip immediately or only after a few seconds.
  • AC trips breaker after 5 minutes or so. The AC starts OK, but after a few minutes, the breaker will trip. This, for example, is typical for the AC compressor tripping breaker (outside AC unit tripping breaker).
  • AC trips breaker after a few hours . An air conditioner will work fine for several hours before it trips the breaker.

To help everybody out, we are going to look at how to check why the AC unit keeps tripping the breaker. We are going to check for 9 key culprits that cause the AC circuit breaker to keep tripping.

There are only two roots for why your AC keeps tripping:

  • You have a faulty breaker . This involves issues with circuit breaker, AC wiring, and electrical short circuits.

As every HVAC professional does, you should check these culprits one by one, eliminating the causes as you go. Once you have correctly detected what is causing the AC breaker to keep tripping and fix the problem, your AC unit should work smoothly again.

Note: For every culprit, we are going to tell you if it causes the AC breaker to trip immediately, after a few minutes, or after a few hours, and explain why.

Here are the most common culprits (listed one by one) for any air conditioner type – be it central air, mini split, portable, or window air conditioner – to keep tripping the breaker. We are going to start with breaker-related issues (#1 to #3) and continue with AC unit-related issues (#4 to #9) :

#1 Circuit Breaker Is Bad, Loose, Or Undersized (Causing AC To Trip Breaker Immediately)

If you are lucky, the AC breaker keeps tripping due to a bad breaker. This is one of the easiest problems to solve; problems with the AC unit itself are harder and costlier to fix.

It’s not uncommon to see a bad circuit breaker. Both new and old breakers can go bad due to wear-and-tear or acute amp surge that fries the breaker. Over time, even well-installed circuit breakers can come loose and cause all sorts of issues, including tripping unexpectedly.

In limited cases, we also see that homeowners have installed a circuit breaker that is just too small. Example: A 3-ton AC unit on 220V has a max. wattage of about 3,600 watts and requires a 25A or 30A breaker. You can check what size AC breaker you need here accounting for NEC 80% ampacity rule .

Dead giveaways of a bad breaker are:

  • Breaker smells like something is burning.
  • Breaker is hot to the touch.
  • Breaker keeps tripping all the time.

Solution: First, you need to check if you have a bad breaker. Secondly, check if the breaker is loose; try to nudge it from left to right to set it back in the required position. Of course, you will also have to check the above article if indeed your breaker is big enough to handle all the amps that you need to run your AC unit.

If you have a bad breaker, you just simply replace it. Get a new one – circuit breakers are quite inexpensive – and be sure to check that it has the same ampacity as the old one. Everybody can DIY breaker replacement; you can consult this guide on how to replace a circuit breaker if you need some help.

Once you have a working breaker again, your AC should stop tripping it.

#2 Wrong AC Wiring (New Air Conditioners Trip Breaker Immediately)

Another possibility, especially for new air conditioners, is wrong wiring. If you have a newly wired thermostat or you have just replaced an old thermostat, chances are that not all wires are connected to the right sockets.

For air conditioners, you will have to connect:

  • Blue or yellow wire is meant for cooling. These wires are connected to the Y terminal in a standard thermostat.
  • Red fire for power, connected to R.
  • Common wire (usually black) connected to C.

wrong thermostat wiring leading to ac breaker tripping

For more advice on how to wire a thermostat, you can consult the thermostat wiring guide here .

Wrong wiring will lead to the outside AC unit tripping breaker immediately (central aircon or mini splits). This is a standard AC compressor tripping issue; the compressor creates a surge of amps that can hit an undersized breaker if it’s wrongly wired.

Solution: Check that all the wires are in the right sockets. In limited cases, you will have to can an electrician to fix this, but most people can use the guide cited above to adequately wire a thermostat themselves.

#3 Electrical Short Circuit (Unsheathed Wires Touching)

Any short circuit can cause a spike in electrical current (amps) that will trip the breaker. In fact, one of the reasons why we use circuit breakers in the first place is to protect our circuits against short circuits.

In the case of wiring air conditioners, the short circuit happens when two exposed wired (unsheathed because the coating has been degrading for years) touch.

Example: Let’s say that the blue and red wire touch. This doesn’t happen if they are properly insulated. However, over time, insulation can decay. When this happens, the electrical current from two wires will travel along a single wire (the one with the least electric resistance, according to Ohm’s law). This will cause a spike in amps that can knock out the breaker.

amp spike causing ac fuse to trip

Admittedly, it’s very difficult to tell if you are experiencing a short circuit. You do have to go to check all the wires to see if the insulation is damaged. This short circuit problem also causes the AC to trip break immediately, after 5 minutes, or even after 10 hours of running the AC unit. It is not time-specific which makes the detection even harder.

Solution: If you suspect that your AC unit tripping the breaker due to a short circuit, you can check the wires yourself or call an electrician. Once you find faulty wires that are causing the short circuit, you have to reapply the coating, or, in more cases, just replace the wire.

All of this, of course, is easier said than done.

Once you have eliminated the thermostat-related problems, you can start checking if there is something wrong with your air conditioner unit, resulting in the breaker tripping repeatedly:

#4 Dirty Condenser Coils (Causing Outside Air Conditioner Circuit Breaker To Trip)

A lot of AC tripping breaker problems are caused by the air conditioner overheating. One of the most common examples of this is the air conditioner circuit breakers outside to trip.

The outdoor condenser coils are exposed to the environment. That means that anything from dirt, leaves, dust, and grass, can find its way into the AC outdoor unit (you may even find a dead rat in there) . If this dirt accumulates on the fairly exposed condenser coils, you will have problems with the outdoor AC unit tripping breaker.

dirty ac coils tripping breaker

These condenser coils are basically superb heat exchangers . They expel all the heat that is generated in the refrigeration cycle. If these condenser coils are coated with dirt, for example, their ability to conduct heat is impeded. Obviously, if the coils can’t give away enough heat, the whole outdoor unit will get overheated.

And overheating leads to the AC tripping the breaker.

In this case, the AC breaker won’t turn trip immediately. It won’t even trip in 5 minutes or so. Dirty condenser coils are one of the most common reasons why the AC trips breaker after a few hours. The AC will overheat in time and that can take anywhere from some 10 minutes to several hours.

Solution: Clean the outdoor condenser coils. Open the outdoor unit and check if there is dirt coating on the coils. If there is, clean out the debris and spray them with detergent or coil cleaners. You can read how to clean the condenser coils on the Carrier website here .

After the outdoor coils are cleaned, they can adequately exchange heat again. That means that all the heat that has to be expelled via the coils will be released into the atmosphere again. As a result of the AC unit not overheating, you will no longer have a problem with AC breaker tripping.

#5 Dirty Air Filters (Restricted Airflow Results In Overheating And Trips Breaker)

Dirty air filters are another common culprit for an AC unit to trip breaker after a few hours.

We all know that every AC should have adequate airflow. If the filters are dirty, they restrict the airflow. This can cause a series of unwanted issues and will eventually lead to AC overheating. And, as we know, if the AC is overheating, it will inevitably trip a circuit breaker.

Everybody pretty much knows what to do with dirty air filters, right?

Solution: Clean or replace the air filters. This will again enable the AC unit to operate at sufficient airflow. The AC unit will not overheat. The AC breaker will not trip. It’s a pretty simple fix.

#6 Compressor Fails To Start (Or Hard-Starting Compressor)

Out of all the things that may go wrong, the compressor-related issues are the worst. When you have a faulty compressor, you will in almost all cases have to replace it. This replacement can be so costly that homeowners with older units usually just replace the whole air conditioning system.

Now, if you have a faulty compressor (the reason might also be a fault capacitor), you can expect two things to happen:

  • Compressor doesn’t start at all. Regardless of this, the AC compressor can still trip the breaker. You will notice that in this case, the AC compressor trips the breaker immediately.
  • Compressor starts slowly (usually takes a few seconds) . This is an indication of a faulty compressor and might lead to the AC compressor tripping the breaker after a few minutes.

The compressor – the main part of the AC – is responsible for compressing the refrigerant gas. If it doesn’t do its job, the AC unit might start overheating and blowing warm (instead of cold) air.

When the compressor doesn’t start at all, there is usually a spike in amps along the compressor wire to the breaker. This will trip the breaker immediately.

If you have a hard-starting compressor, the breaker won’t trip immediately. Nonetheless, such a compressor repeatedly can repeatedly send amp spikes towards the breaker in order to keep running. Eventually – usually in a few minutes or so – one of these amp spikes will overwhelm the circuit breaker and the breaker will flip.

Solution: This is a hard pill to swallow but you will probably have to replace the AC compressor. This is a complex replacement process you can’t do yourself; you will require an HVAC professional to do it for you.

You can, of course, take this ‘opportunity’ to replace the AC unit altogether. If your AC unit is past its prime (15+ years old), replacing the whole air conditioner makes sense in many cases.

#7 Compressor Is Grounded (Wires Touching The Sides)

Another problem a compressor might have – much less troublesome – is some wire displacements. Namely, the electrical wires that power the compressor are unsheathed and touching the compressor casing. It’s always best to check if everything is OK with the compressor wires.

Of course, if the wires touch the metal casing, all that electricity will go to the ground (we talk about the compressor being grounded). Inevitably, this will cause a spike in amps that will knock out the breaker.

Now, this may happen when you turn on the AC, after a few minutes, or even after several hours. The vibrations in the compressor pretty much displace one wire so much that it touches the casing, and that may happen immediately or even after some hours.

Solution: Check if all the wires that go in and out of the compressor still have their insulation coating on them. Also, check if the wires are neatly packed and away from the casing. If you find an exposed wire close to the casing, it’s very likely this is the wire that keeps tripping the AC breaker.

Use a plastic or nylon line to fix the wire in place, away from the casing. You can even replace that wire if you see that the insulation coating is severely damaged. After you do that, your breaker should stop tripping.

#8 Low Refrigerant Levels (Lines Leaking Freon)

All air conditioners work based on the refrigerant cycle. For this cycle to work properly, the lines have to be full of freon (refrigerant gas like R22, R410A, and so on). If you have a leak in the refrigerant lines, there will be less refrigerant within the lines which will lead to AC overheating and potentially tripping the breaker.

Example: If your window AC keeps tripping the breaker, the refrigerant leak could be the culprit.

Solution: You have to check if the refrigerant levels are indeed low by measuring the refrigerant pressure. If freon is indeed leaking out, you will first have to seal the leak and then recharge the AC unit.

In most cases, you will need professional help for this.

If you want to know how a professional refills the freon, you can consult this article about how to recharge a window air conditioner .

#9 Faulty Fan Motor (Leading To Overheating And Breaker Tripping)

In limited cases, we also see that a faulty fan motor is responsible for the outdoor AC unit tripping a breaker after a few hours.

The outdoor fan produces airflow that expels the heat into the environment (cooling the condenser coils). That fan is powered by the motor. If the motor doesn’t produce adequate power output, the fan doesn’t produce adequate airflow, and the outdoor AC cooling process is impeded.

bad fan motor causing air conditioner to trip breaker

This can lead to AC overheating and tripping the AC breaker. This happens when the AC is overheated enough; it takes a few hours (not on start-up or after a few minutes).

Solution: Check if the outdoor fan is spinning. If not, the problem might be a faulty fan motor. You will probably need to replace it. Before you do that, do check out all the reasons why outdoor AC is not spinning here . Namely, a faulty fan motor is not the only reason why the condenser fan is not spinning.

After you fix this and the fan is spinning again, there won’t be overheating, and the outdoor AC unit will stop tripping the breaker.

How To Call If You Need Professional Help?

As we have seen, both the diagnosis of why the AC keeps tripping the breaker as well as the fixes are not a piece of the case.

From checking the breaker to checking if something is wrong with your AC unit, there is quite a lot of knowledge (and experience) that guys fixing AC units should have.

This article was a general overview of the causes for AC to keep tripping the breaker. If, however, you realize you will a professional help, you can turn to your local HVAC companies.

We hope this helps somebody figure out why the AC keeps tripping the breaker and how to go about fixing it by themselves or with professional help.

Trane XR-13 Model 4TWR3048A1000AA 23.1 RLA Manufacture Date 11/2009 Unit runs for anywhere from 2 minutes to half a day and then trips the breaker. Breaker is 50 amps. When unit trips, there is a loud popping sound like an electrical short to ground. Measure amp draw from each leg coming from the contactor to the compressor is approximate 13.1 amps. I cleaned the coils, but problem persists. If the compressor was shorted, the breaker would trip immediately, but this trip is a slow process. Amp draw is steady until the pop and breaker trip. Any ideas on next steps? I am handy and can change the breaker, replace the capacitor, etc. But would rather diagnose the problem before changing random parts. Thanks for your ideas.

Key Takeaways

  • An AC breaker can trip if it is overloaded with many appliances, if there is a short circuit in the unit, or if the breaker is not sized properly.
  • Dirty and faulty components in an AC can often cause a breaker to trip frequently. It is also possible for a malfunctioning breaker to be the culprit.
  • Electrical faults are very dangerous and you should not attempt to fix them yourself. Hence, always consult with an HVAC professional.

When the AC is tripping your electricity, it’s important to pay attention and quickly diagnose the problem.

As an experienced HVAC professional, I know all the common issues that can cause your AC system to trip the breaker.

I’ll share my knowledge and help you get your air conditioner running again quickly.

13 Common Reasons Why Your AC Trips The Circuit Breaker (Solutions Included)

AC electrical faults cause 86% of dangerous air conditioner fires[ 1 ], and circuit breakers help you stop that from happening - but only if you know why it’s happening and what to do next.

1. The Sizing Of The Breaker Is Improper

Circuit breakers are rated by amp s , determining the amount of current that can flow through without tripping the breaker.

The average home circuit breaker is 15-20 amps for the branch circuit , which is plenty for most home AC units, but larger air conditioning systems using too many amps can cause the circuit breaker to trip[ 2 ].

You can either:

  • Move your air conditioning unit to a different place/room with a larger AC circuit breaker,
  • Hire a professional to upgrade the breaker and accompanying wiring.

TL;DR:  If rated amps of a circuit breaker are lower than the rated amps of the AC, it will always trip.

2. You Are Overloading The Circuit

Each circuit breaker can only handle a certain amount of amps.

If you have other devices running through the same circuit breaker as your air conditioning system, it can o verload the AC circuit breaker and shut off your power.

Reroute other electrical devices so your AC unit can run through the breaker independently. You may need a professional to help.

TL;DR: A dedicated circuit is recommended for an AC. If too many appliances are connected to the AC circuit, it can get overloaded resulting in breaker tripping.

3. There Is A Short Circuit With The Electronic Components

ACs have internal electrical components that run continuously for hours.

Over time, the wires within the air conditioner can become damaged, leading to a ‘short’ (or short circuit)[ 3 ].

A 'short' means too much electricity is flowing through the wires and can cause overheating and fires.

The air conditioner circuit breaker will trip to shut off power and protect your home from danger.

You need to contact a professional to find the source of the short circuit and make appropriate repairs.

Electrician Fixing AC breaker

TL;DR: A short circuit is a very dangerous condition as it is a sign of damaged electrical components. Seek professional help if you suspect this is the case.

4. A Dirty Air Filter Heating Up Your AC

The air filter in your AC unit will get dirty over time as air flows through the machine (more so with an outdoor unit than an inside unit).

If the air filters become too dirty, they can reduce airflow and cause your air conditioner to overheat, as the electric motors must work harder.

Your air conditioner will try to draw more power to compensate for the poor airflow, tripping the breaker.

Change or clean the dirty air filter to stop your AC system from tripping the breaker.

You should be able to replace the air filter and perform regular maintenance yourself.

Important Note:

It is crucial to point out that you should avoid DIY maintenance if you have the slightest hint of doubt that things may go wrong. To avoid harming yourself or damaging your unit, always consider hiring professional help. 

5. Dirty Condenser Coils Can Also Heat Up Your AC

Your condenser coils absorb the heat from the air, but they can become blocked by dust or debris (particularly if you have a dirty outside unit).

The dirty coils can strain your air conditioning system, causing it to work harder and draw more electricity. 

They may lead to it tripping the breaker.

Cleaning dust and debris off the dirty condenser coils should stop the AC tripping.

You should also have an AC technician check and perform annual maintenance on your condenser.

TL;DR: Dirty filter and dirty condenser coils can heat up the internal components. Higher heat results in higher current draw resulting in your breaker tripping. Perform regular cleaning of these components.

6. Problem With Coil Fan Motor

Air conditioners use a coil fan (or AC blower) to move hot air over the condenser coil and disperse heat, leaving you with cold air.

Your coil fan can become damaged over time , and a broken coil fan can cause the AC to draw too much power, leading to the breaker tripping.

Hire a professional to perform AC repair work on the coil fan motor. It may need to be replaced to stop the breaker tripping.

TL;DR: A broken coil fan motor can draw more than its rated current, which in turn can trip the breaker.

7. Your Compressor Has Gone Bad

Your compressor houses the refrigerant that cools the air, but a faulty compressor won't cool the air.

Faults become more common as a compressor ages but can happen because of accidental damage.

A bad compressor can cause two issues:

  • Hard starting.  Your faulty compressor won't start up properly and draws more power to try and compensate, causing it to trip its own breaker.
  • Grounded compressor. The wires connected to the compressor come loose, leading to a short circuit and a tripped breaker.

A technician can install a hard start kit to try and get the compressor started.

However, a faulty compressor can mean costly repairs, and it's often best to replace the entire system rather than try to fix it.

Air Conditioner Compressor Outside a Room

TL;DR: If the compressor is hard starting or if it is grounded, then it will draw far more than its rated current.

8. Cables And Wires Wear And Tear

Your AC runs has wires running inside the whole unit connecting electrical components.

Over time, the wires and wire insulation can become loose or damaged.

Loose wires touching the ground, floor, or other components can cause further damage to the device and your home.

The circuit breaker trips as a safety measure to avoid an electrical short and prevent damage.

Some electrical wires can be an easy fix, but electrics can be dangerous.

Have an HVAC technician check the electrical panel of the unit, find the damage, and perform the AC repair safely.

A loose wire or a grounded wire is a dangerous safety hazard. You should avoid touching or going near the unit if you spot a loose connection.

9. Too Little Refrigerant

Refrigerant is the working fluid in an AC unit that cools the air.

The AC compressor has a closed system for the refrigerant, but over time, refrigerant lines can become damaged.

This damage can lead to refrigerant leaking out.

The AC compressor coils will have to work harder to cool the air if there's less refrigerant.

The unit draws more electricity to compensate, which trips the breaker.

Hire a professional to top up the refrigerant and seal the leak.

However, it may be cheaper to replace cheaper portable ACs than perform the repairs if it's out of warranty.

Refrigerant is a dangerous substance and can only be handled by professionals.[ 4 ]

Refrigerant Charging for AC

TL;DR: Lower refrigerant means that the AC has to work harder in order to cool. This in turn means using up more amps to compensate. More amps = breaker tripping.

10. Frozen Evaporator Coil

Dirt, debris, and grime can build up on the evaporator coil, preventing heat from flowing and causing the coils to freeze.

The air conditioner will try to draw more energy to compensate for the frozen coils , but as it draws more amps, it can cause the breaker to trip.

You can fix this yourself by turning the power off and thawing out the compressor using a hair dryer.

Once dry, clean the evaporator coils to prevent them from malfunctioning and freezing over again.

If your air conditioner keeps tripping after this, contact a professional to determine the root cause.

11. It’s Too Hot Outside

Your air conditioner has to work harder in hot conditions to maintain the temperature, which can cause it to draw more electricity and strain the wiring.

It can also cause the breaker to trip to prevent overheating or fire hazards.

Clean the AC to keep the unit cool by improving airflow, and only use the air conditioner when needed.

If it keeps tripping the breaker, you may need to buy a new AC.

TL;DR: If the internal components are heating up due to very hot weather outside then this can lead to the breaker tripping to avoid fire hazards.

12. Failing Air Conditioning Capacitors

Your AC capacitor provides the initial jolt of electricity so it can start.

Capacitors wear out over time, and if you notice your AC has trouble starting or keeps tripping, the capacity may be failing.

Contact an HVAC professional to fix or replace the bad capacitor.

13. You Have A Defective Circuit Breaker

A circuit breaker can become defective through natural wear and tear, exposure to extreme temperatures, or by electrical faults tripping the breaker too frequently.

A defective breaker can trip your electricals every time you use your AC.

First, make sure the breaker is actually defective. 

Circuit breakers trip electrics and protect your home, a nd you should only replace them as a last resort.

If you don't resolve the issue, the new breaker will continue to trip.

Check the other common causes on the list or consult an HVAC technician to determine the issue. A professional will need to replace the circuit breaker.

TL;DR: If all else is fine, then the likely culprit is a defective breaker. Most homes have a spare breaker which you can switch your AC to. If not, then a breaker replacement will be necessary.

When To Call Professionals For Maintenance Or Repair

I recommend calling a professional to help with most air conditioning electrical problems because it can be dangerous.

Always consult a professional if you experience any of the following:

  • 1 There is a burning smell from the breaker or AC: A burning smell indicates that your electrical wiring or AC breaker is overheating. It's a dangerous fire hazard, and you should shut off the air conditioner and contact an HVAC technician immediately.
  • 2 There are crackling or electrical sounds from the breaker or AC: Strange noises from your inside unit usually indicate an electrical issue, loose wiring, or short-circuiting - often in the compressor motor. It is dangerous to fix yourself, and you need to contact an AC Tech professional to undertake air conditioning repair work.
  • 3 You cannot point out where the issue lies: Your AC breaker trips the electrical supply for a reason, usually to protect you from serious danger. If your unit is tripping the AC breaker and you can't find the issue, you need to call an HVAC technician as soon as possible to diagnose the problem.

TL;DR: Electric works should always be carried out by professionals. However, some very alarming signs such as burning smell and crackling electrical sounds call for an immediate inspection. Shut off your home's main electric breaker if you experience these signs.

AC Breaker Keeps Tripping? Here’s What You Need to Know for a Quick Fix

We know this can be a bothersome problem, but we’re here to help you get it sorted out quickly and easily. An AC breaker that trips often is usually caused by an issue with your circuit wiring or by a malfunctioning appliance.

If your AC circuit breaker keeps tripping, there are several potential reasons.

Identifying the source of the issue before attempting any repairs is essential. Once you’ve identified the source of the problem, we’ll explain how to take care of it in just a few simple steps. If your AC breaker keeps tripping and you’re looking for a quick and easy fix, this article is for you!

What Is an AC Breaker?

An AC Breaker is a crucial safety feature in your home’s electrical systems that helps protect against overloads and short circuits. It works by breaking the circuit and cutting off electricity when it senses an overloaded or short-circuited wire.

You can find these devices in your main electrical panel, as well as individual outlets and switch boxes throughout your home – making sure that you and your family are always safe from harm.

The AC breaker consists of two parts: a circuit breaker switch and a trip indicator. The circuit breaker switch is responsible for cutting off power when it detects an overload or short circuit – this prevents further damage to your wiring and appliances.

The trip indicator shows whether the breaker has been tripped, allowing you to reset it if necessary.

Why Do AC Breakers Trip?

If your AC keeps tripping the breaker, the most common causes are either too much current being drawn from one circuit or a short circuit caused by faulty wiring or a damaged appliance.

If any of these conditions are present, it can cause the breaker to trip and shut off the power to that area of your home.

Other potential causes include a failed motor or compressor in your air conditioner or even dust accumulation on the breakers themselves.

What To Do When Your AC Breaker Trips

Is your AC tripping the breaker? It can be an annoying and inconvenient issue to deal with. But don’t panic – there are a few simple steps you can take to try and fix the problem.

Check your air conditioner’s filter. A clogged filter can cause the breaker to trip by overloading the circuit. Replace or clean it if needed.

Look for any signs of damage on the wiring leading up to the AC unit. If the wiring looks frayed or damaged in any way, call a licensed electrician for help as soon as possible.

If none of these solutions work, it might be time to upgrade your electrical panel or have an electrician install a higher-capacity breaker specifically designed for your air conditioning system. By taking these steps now, you can avoid costly repair bills down the road and get back to feeling comfortable in no time!

Common Causes of AC Breakers Tripping

There are many possible reasons why your AC unit keeps tripping the breaker. Below, we’ll take a look at some of the most common.

A Dirty Air Filter

One of the most common causes of an AC breaker tripping is a dirty air filter. When an air filter becomes clogged with debris, it can cause your system to work harder than it needs to and eventually trip the breaker.

You’ll want to ensure you regularly check and replace your air filters to keep them clean and functioning properly.

Dirty Condenser Coils

Another potential culprit for a tripped AC breaker is dirty condenser coils. These coils are responsible for releasing heat from the system, so if they become covered in dirt or other debris, they won’t function as efficiently and could potentially cause your breaker to trip.

Make sure you routinely inspect and clean your condenser coils for optimal performance. If your AC trips the breaker after 5 minutes of working, this is a possible cause.

Broken Coil Fan

A broken coil fan could also be causing your AC’s breaker to trip. The fan helps circulate cool air throughout the room, but when it stops working properly, this disruption can put a strain on the system and cause it to trip the breaker as a safety measure.

If you suspect that your coil fan may be malfunctioning, contact an HVAC technician right away so they can diagnose the issue and repair any damages quickly.

Problematic Compressor Start-up

One of the more common causes of an AC breaker tripping is a problematic compressor start-up. If your compressor is having trouble starting up, it can draw too much current and cause the breaker to trip. This problem is usually caused by faulty wiring or parts, such as a capacitor or motor winding.

Loose Wiring or Faulty Parts

Loose wiring or faulty parts are also frequent culprits behind AC breakers tripping. Loose connections can create dangerous arcs that will cause the breaker to trip.

Additionally, if some internal part in your AC unit has become damaged and isn’t working properly, it could also lead to an overload that trips the breaker.

Too Little Refrigerant

Another common reason for AC breakers tripping is too little refrigerant in the system. This can happen when there’s a leak in the system somewhere, which causes the refrigerant levels to drop below the required amount for your AC unit to work properly.

When this happens, your unit will have difficulty cooling down and not be able to handle large loads efficiently—causing it to trip its own breaker as a safety measure.

The Compressor Is Grounded

If your AC’s compressor is grounded, then it could be the cause of your breaker tripping. This can happen if a wire becomes loose or disconnected or if the wiring around the compressor has been damaged due to corrosion or wear and tear.

To check for this issue, you should inspect the wiring and connections around the compressor. If all looks okay, you’ll need to call in a professional to take a closer look.

The Evaporator Coil Is Frozen

Another common cause of an AC breaker tripping is a frozen evaporator coil . This occurs when air isn’t flowing properly through the unit, and as such, causes an overload on the system, which trips the breaker switch.

To fix this issue, you’ll need to clear any blockages from your AC vents so that airflow can be restored. You may also need to replace any broken parts inside your unit for optimal performance and safety.

The Circuit Breaker Is Faulty

If your AC circuit breaker keeps tripping, it’s possible that your circuit breaker itself is faulty and needs replacing in order for it to operate correctly again. A qualified electrician will be able to diagnose whether this is an issue by testing the circuit breaker for any signs of wear or damage.

A qualified technician can accurately diagnose why your AC circuit breaker keeps tripping.

If you do find yourself needing a new one, ensure to get one with an appropriate amperage rating that matches up with your home’s electrical system requirements!

While the steps listed above are excellent ways to identify why your AC breaker keeps tripping, we wouldn’t recommend working with electricity without some form of training. The problems are often relatively minor, but the risks involved when working with electricity simply aren’t worth it to save a few bucks.

The bottom line is that if your AC breaker keeps tripping, the best thing to do is to call a qualified AC technician for help. An experienced technician can diagnose why your AC breaker keeps tripping and then take steps to ensure it doesn’t happen again.

While it may seem like a hassle, having your AC breaker checked out by an expert can help you avoid costly repairs down the road. Safety should always come first when dealing with electricity – so don’t take any chances!

If you have an AC unit, you’ve probably wondered how long it will last. And why wouldn’t you? You’ve spent a lot of money on your unit.

When it comes to keeping your home comfortable, the choice between a heat pump and central air conditioning can feel like a crossroads. Each…

Why is My AC Tripping the Circuit Breaker?

October 04, 2021

ac trips breaker after 10 minutes

Air conditioners are vital to Floridians, so it's no surprise that homeowners would be stressed if their AC suddenly started turning off.

If this is happening to you now, it’s likely a tripped circuit breaker. When your AC trips the circuit breaker after running for only a few minutes, your breaker cuts the power to the AC system.

Why is your AC tripping the circuit breaker? Many issues can be at play, but the primary 3 reasons include:

  • An overloaded circuit
  • A grounded compressor
  • A faulty breaker

We’ll review how to reset your circuit breaker to see if that restores your AC’s power. If it doesn’t, we’ll dive into the potential problems related to a tripped circuit breaker and how to troubleshoot them.

Want a professional to identify and fix your AC’s tripped circuit breaker? Contact Advanced Air for an AC repair . We provide punctual and round-the-clock service .

Reset your circuit breaker

Reset your circuit breaker to see if it stops tripping

Before we look at what could be causing the frequent tripping, let's first try resetting the circuit breaker. You can do so by:

  • Let the unit cool down for about 5 minutes. The Department of Energy recommends letting the unit rest before resetting any breakers.
  • Turn off your thermostat.
  • Locate your gray main circuit panel by checking your closets, garage, or basement. Make sure there's no water on the ground in the room with the panel. If there is, do NOT stand in the water while resetting the breaker.
  • Find the AC switch. The breakers are typically labeled. If not, look for the switch that is either in a middle position or OFF. Some manufacturers have a visible color indicator that shows that a breaker has tripped.
  • Push the switch OFF unless it's already OFF. If already OFF, skip to Step #6.
  • Push the switch ON. You should feel a satisfying click into place.
  • Wait for 30 seconds.
  • Turn your AC back on to test.

If your AC immediately trips again, do NOT reset the breaker again until the cause is corrected. Multiple overcurrents, or surges of electricity, can damage your AC and even start a fire.

Read on to learn about the potential issues causing your AC to trip the circuit breaker.

Three main reasons behind your AC tripping the circuit breaker:

1. an overloaded circuit.

Circuit breakers shut off the flow of electricity whenever the number of amps (a unit of electrical current) exceeds its amp rating. For example, if the circuit breaker has a rating of 15 amps, it'll trip whenever 20 amps flow through the circuit.

So, whenever your AC is using too much energy, it's pulling in more amps than usual, causing a surge and your circuit breaker to trip.

Your air conditioner can use too much energy if:

The air filter is dirty:

Why is My Air Filter Black?

An Advanced Air technician can help you replace your filter

Air conditioners need air to be flowing into the system to cool your home enough to meet your set temperature.

When air filters get clogged with debris and dirt, they block airflow from entering the system. Your AC now has to compensate by working harder and using more electricity to cool your home. The circuit breaker isn’t used to this amount of energy consumption and trips to protect your AC.

The condenser is dirty:

Our technicians can help clean your condenser

Your AC's outdoor unit is called the condenser. It plays an essential role in keeping your home cool by dumping the heat your indoor unit absorbs from your home's air outside.

When the condenser is dirty or blocked by bushes, your outdoor unit can no longer effectively transfer the heat outside, and your AC has to use more energy and take longer to cool your home. This increase in needed power trips the circuit breaker.

The condenser fan doesn't work correctly:

As we mentioned above, the condenser is your outdoor AC unit. The condenser's fan helps dissipate heat back outside. If you stand next to the condenser and can't hear the fan rumbling, it's likely broken.

When the fan’s motor is broken or worn out, the electricity from your AC system to the motor has nowhere to go and is flowing freely. Your AC will automatically detect this issue and trip your circuit breaker to prevent the wires from frying and damaging your system or home.

The refrigerant is leaking:

What is refrigerant? It's a cold substance in your AC that helps the indoor unit absorb heat from the air. Leaking refrigerant means your AC can't cool your home as effectively due to reduced heat absorption abilities, forcing it to use more power and tripping the breaker due to overload.

How do you know you have a refrigerant leak? You can tell when:

  • You see ice forming on the condenser
  • You hear hissing or bubbling noises coming from your inside AC unit
  • You have higher than normal monthly energy bills

Advanced Air technicians can diagnose the problem behind your circuit tripping

If you suspect your breaker keeps tripping because of any of these reasons, try changing out your air filter monthly and booking an appointment with an AC technician to clean the condenser. Also, make sure to check your condenser's fan and inspect the refrigerant lines.

2. A shorted compressor

Typically, electricity flows in a loop called a circuit. When a compressor "shorts," it's because a malfunction interrupts the loop, allowing too much electricity to flow through the circuit. The circuit breaker then trips to shut off electricity to prevent the overload from potentially causing a fire.

Most malfunctions are because of a winding, where electrical currents pass through inside the compressor, breaking and not being able to handle its load anymore. The additional electricity ignites the oil in the compressor, causing a sudden current surge that burns out the compressor and forces the circuit breaker to trip.

Unfortunately, a burned-out compressor most likely needs to be replaced because a functional compressor is vital as it pumps refrigerant throughout your system.

Replacing the compressor can be expensive if you don't have a valid warranty. If you have a valid warranty, financing options can help. Or, you might want to look into replacing your system entirely. You can use our handy AC installation cost calculator to see if a replacement would be more cost-effective than replacing your compressor.

3. A faulty breaker

ac trips breaker after 10 minutes

A damaged circuit breaker

Your circuit breaker may keep tripping because of an issue with the breaker itself.

To determine if the breaker is damaged, find your home's main circuit panel and look for indicators that you have a faulty breaker, such as:

  • The breaker is hot when you touch it
  • You can smell a burning odor near the breaker
  • You see loose connecting wires
  • You see burn marks on the breaker
  • You see obvious worn-out parts

If you notice any of the above indicators, you're dealing with a faulty breaker that needs professional replacement. Call a technician immediately.

“My AC Works But It Keeps Tripping the Breaker”

Breaker panel with door open

Does your air conditioner cool for a while but then trip your circuit breaker and shut off?

Typically, your AC breaker trips when there’s a short circuit, the AC is overworking or a part is bad or malfunctioning.

If you continue to run your AC, you could permanently damage the air conditioner. Get a professional AC repair tech out as soon as you can.

Now let’s look at the specific causes of an AC tripping the breaker.

Specific AC problems that can trip your breaker

Dirty air filter.

If you leave your air filter in so long that it is completely clogged with dirt, it can suffocate your AC, causing it to work much harder than it should, overheat, and trip the breaker.

Dirty condenser coils

These coils, located in the outside AC unit, are designed to release the heat from your home to the outside. But if they’re covered in dirt, they can’t do that. (It’s like you trying to cool off while wearing a wool sweater).

Bad capacitor

A capacitor is responsible for starting and keeping your air conditioner running. If it goes bad, it can pull too much electricity and trip your breaker.

Old or weak compressor

The compressor is in your air conditioner’s outdoor unit. A weak compressor has trouble starting. When it does try to start, it may try to pull too much electricity, which will trip your breaker.

If this is the problem, an air conditioning professional might recommend installing a hard start kit.

Loose electrical connections

Wires expand and contract as the weather changes, which can cause loose electrical connections inside of your air conditioner and result in a short circuit.

Another mechanical problem

There are numerous small mechanical problems that could also be causing your AC to trip your breaker.

If you suspect a power surge or spike is the cause, unplug the air conditioner and check the circuit breaker. If it is still tripped, you may need to reset the breaker or have an electrician look at the system. When the breaker trips again, there may be a problem with the air conditioner itself and you should call a repair technician.

How to reset ac circuit breaker?

If your air conditioner keeps shutting off, it may be time to reset the circuit breaker. Circuit breakers are designed to trip when they sense an overload of electricity. This protects your air conditioner from damaging itself with too much power. To reset the circuit breaker, find the breaker box and flip the switch to the “off” position. Wait a few minutes, then flip it back to the “on” position. If the breaker trips again, it’s time to call a professional to help you troubleshoot the problem.

Ac compressor tripping after few seconds

If your AC compressor is tripping after just a few seconds of operation, there could be several reasons behind it. One possible cause is an electrical issue, such as an overloaded circuit breaker or a short circuit. To address this, it is recommended to contact a qualified electrician who can inspect and resolve the problem.

Another potential cause could be dirty condenser coils, which can impede airflow and cause the compressor to overheat. To rectify this, ensure that the coils are clean and free from debris. You can either use a coil cleaner or seek assistance from a professional HVAC technician to spotless them.

Low refrigerant levels can also lead to the compressor tripping. If the refrigerant levels are too low, it may indicate a leak in the system. To address this issue, it is best to contact a professional HVAC technician who can locate and repair the leak and then recharge the refrigerant to the appropriate levels.

A faulty capacitor is another possible culprit. The capacitor provides the initial power boost required to start the compressor. If it is defective or failing, it can cause the compressor to trip. A qualified technician can test the capacitor and replace it if necessary.

Finally, the compressor motor may be experiencing excessive load or mechanical issues, resulting in frequent tripping. This could be due to a faulty motor or compressor itself.

When your air conditioner is tripping your circuit breaker, don’t ignore the problem. It could be a simple fix, or it could be a sign of a more serious problem. Either way, it’s best to have a professional take a look to be safe.

Can a bad ac capacitor cause the breaker to trip?

If your air conditioner’s capacitor is bad, it can cause the breaker to trip. The capacitor is responsible for providing the electrical current that helps start up the compressor. If the capacitor is damaged, it can’t provide the necessary current, which can cause the breaker to trip.

Refrigeration compressor tripping breaker

If your refrigerator’s compressor is tripping your breaker, there are a few possible causes. The most common cause is a faulty compressor start capacitor. A start capacitor gives the compressor a boost of energy to start, and if it’s failing, the compressor can’t start properly. Another possibility is that the compressor itself is faulty. If the compressor is drawing too much power, it can trip the breaker. This is usually caused by a problem with the compressor’s internals, and will require a replacement. Finally, it’s possible that the breaker is simply too small for the refrigerator. If the fridge is new or has recently been upgraded, the breaker may not be able to handle the increased load. In this case, you’ll need to upgrade the breaker to a higher capacity.

Air conditioner circuit breaker outside

If your home doesn’t have central air conditioning, you may have an air conditioner circuit breaker outside. This circuit breaker controls the power to your air conditioner unit. If the circuit breaker trips, it will cut off power to your air conditioner unit. This can be a problem if the weather is hot and you need to cool down your home. To reset the circuit breaker, you’ll need to locate it first. It should be near your air conditioner unit. Once you’ve found it, flip the switch to the “off” position and then back to the “on” position. This should reset the circuit breaker and restore power to your air conditioner unit. If the circuit breaker trips again, it’s possible that there is a problem with your air conditioner unit. You may need to call a technician to come and take a look at it. In the meantime, you can try to cool your home down with fans.

Why Does My Air Conditioner Circuit Breaker Keep Tripping?

The most common reason for an AC breaker to trip is because it is overloaded. This means that there is too much current flowing through the breaker, and it trips to protect the circuit. Other reasons for an AC breaker to trip include a short circuit, a ground fault, or a faulty breaker.

6 REASONS YOUR AIR CONDITIONER KEEPS TRIPPING THE CIRCUIT BREAKER

Circuit breaker panel with cover open

So, you've determined that your AC is tripping the breaker, but you're clueless as to why.

Well, an air conditioner usually trips the breaker because it's pulling in more amps than the breaker is rated for. That is, if you have a 20-amp breaker and the AC pulls 30 amps, the breaker trips.

That's why breakers trip: to protect you from over currents that can damage equipment and cause fires (yikes).

So DON'T keep resetting the breaker and letting it trip. Constant tripping can harm equipment and cause a fire. Find the cause of the problem first.

Common causes of an air conditioner tripping the breaker include:

  • Dirty air filter
  • Dirty outside unit
  • Issue with the circuit breaker
  • Motor has shorted
  • Compressor has trouble starting
  • Compressor is grounded

You can fix the first problem yourself, but everything else requires an AC repair technician.

Read on to learn why these problems cause an AC to trip the breaker.

Or you can schedule an AC repair with us right away if you live in the metro Atlanta, GA area .

Now, on to the reasons your AC keeps tripping the circuit breaker

  • Dirty air filter Imagine forcing a pillow over your face. Hard to breathe right? That's what a dirty filter does to your AC blower; the blower has to work longer and harder to circulate air through the filter. This causes the blower to draw more electricity and trip the breaker. Solution : Change the air filter.
  • Dirty outside unit Your AC system has an inside unit and an outside unit. The inside unit absorbs heat from your air using refrigerant. That refrigerant flows to the outside unit to disperse the heat. However, the outside unit can't disperse heat well if it's super dirty because dirt is an insulator. So the AC runs and runs trying to disperse that heat outside until-click-the breaker trips due to drawing too much current. Solution: Get an AC tech to properly clean the outside unit. You may be thinking, "Why can't I clean it myself?" Well, you lack the cleaning equipment and cleaning chemicals to clean the condenser coil professionally (and buying the wrong type of equipment can do more harm than good to the condenser). Plus, cleaning it improperly could damage/flatten the fins wrapped around the coil. This blocks airflow over the coil and is just as bad as having the coil matted with dirt.
  • Issues with the circuit breaker The issue may not be with the AC itself but rather with the breaker. Wires connected to the breaker may be loose or the breaker itself may be bad and needs replacing. This is a relatively inexpensive fix. Solution: Have a tech tighten connections to the AC's breaker or replace the breaker.
  • Motor has shorted Electric motors in your AC can run for hours and hours and can take quite a bit of abuse. But if a motor runs hot for too long, the wire insulation can break down, leading to an electrical "short." A "short" is where electricity bypasses its normal path, (so it's taking a "shortcut"). This shortcut allows more electricity to flow than the wires can handle, causing the wires to overheat, melt and cause a fire. Of course, before the fire happens, the circuit breaker trips. Solution: Call an AC repair technician to find the source of the short.
  • Compressor has trouble starting The heart of your AC system is the compressor. It pulls tons of electricity when it starts up. Unfortunately, as the compressor ages, it has trouble starting (called hard starting) and pulls even more electricity, causing the breaker to trip as a result. Solution: Have an AC technician install a "hard start kit" which is a capacitor that gives the compressor motor an extra electrical "jolt" to get it moving. However, the compressor may be old or damaged and need to be replaced instead.
  • Compressor is grounded A "grounded compressor" or "compressor short to ground" means that an electrical winding inside the compressor has broken and hit the side of the compressor. This causes a direct short to ground, igniting the oil and causing a burnout. And, of course, the circuit breaker trips due to the sudden current surge. Solution: This is the worst-case scenario. An AC tech will have to replace the compressor and clean the refrigerant lines. If your compressor is out of warranty (or your warranty never covered it), you might as well replace the entire outside unit. Cheaper that way. (Compressors are pricy.)

5 Reasons Your A/C Is Tripping Your Circuit Breaker (And How To Fix It)

by John Dawson | Aug 17, 2021 | AC repair billings mt , HVAC Tips Billings MT

Why Is Your AC Tripping Your Circuit Breaker? 

If you notice that your AC is tripping the breaker, then it may be time to contact a professional. There are many reasons why this could be happening, and each of them requires different solutions. 

For example, if you notice your AC system is tripping the breaker when it gets too hot outside, then you might need an ac pro to come out and give your unit a tune-up. 

Sometimes air conditioners will cause circuit breaker trips because they are not getting enough electrical current from the AC circuit breaker, or there may be something wrong with the wiring in your house. 

Let’s take a look at the top five common causes for why your air conditioning system could be tripping your circuit breaker. Finding the issue and trusting a professional with your AC repair can keep your family cool and safe this Summer!

AC Acting Up?

Is your AC acting up? Don’t put up with warm air- our team is here to help!

1. A Dirty Air Filter 

If you notice that your AC is tripping the breaker when it gets too hot outside, a dirty air filter may be to blame.  Dirty filters can reduce airflow and cause AC units to overheat, resulting in a breaker trip. 

They also make it difficult for air conditioners to function efficiently at colder temperatures, so you might notice your AC is not cooling your home like it used to.

Air filters should be cleaned every few months depending on how often you use your air conditioning unit and where you live (it might need more cleaning if there are many allergens or plants in your area). 

Your best option is always going to be calling in an HVAC technician who knows precisely what they’re doing when dealing with electrical wiring like this. If somebody with proper HVAC training is not appropriately handled, there could be severe consequences for both property and personal safety.

2. Dirty Condenser Coils

When your condenser coils get dirty, they cannot disperse heat from inside the house to the outside unit .  This can cause the air conditioning system to lead to an electrical short, which can overheat. 

Even when it is running, the A/C unit requires more electrical current to push the heat out of your home, which leads to a short circuit. 

Dirty coils are usually caused by a buildup of dirt, dust, or plant life in your outdoor unit. Cleaning out these coils will help you avoid future ac problems like this!

To prevent dirty condenser coils, you want to make sure that your AC pro is coming out and doing regular tune-ups on the unit.  Tune-ups should be done at least once per year to prevent heat loss in your home during these hot summer months!

An AC pro will also know how often a coil needs to be cleaned or replaced. Some units don’t need cleaning until they are no longer working correctly, while others may only need an annual cleaning depending on their age and performance level. 

3. Broken Coil Fan

Air conditioning units use fans inside them called “coil” fans for cooling purposes, which are often powered by motors outside the house. This fan blows over the coils to release heat from your inside unit. 

If there is something wrong with these motors – whether they have been damaged through wear and tear over time or if they were cut out during construction work nearby-then this could result in increased energy usage and cause the coil fan to burn out sooner than expected.

If your air conditioner fan motor is tripping the breaker because it’s not getting enough power from your circuit, then a broken coil fan may be to blame.  Broken or missing parts of an ac unit can cause this issue that results in higher electricity usage and possible breakers trips. 

To fix this problem, you’ll need an HVAC pro who knows how to replace or repair the coils on air conditioning!

4. The Compressor Is “Hard Starting”

The compressor is an essential part of your AC unit, and as the compressor ages, it may experience problems starting up. If the circuit breaker keeps breaking, you might need to have an HVAC technician check the flow of electricity between the fan and your circuit. 

A running AC unit should switch on in about one second – so anything longer than that could be a sign that you have an issue with your compressor. 

If your compressor is “hard starting,” you will need to call a professional to diagnose the issue. The entire compressor may need to be replaced, plus the refrigerator lines will need to be cleaned to ensure no particulates are in the lines that can cause problems down the road. 

5. Loose Wiring & Aging A/C Parts

Your A/C unit is a complex maze of wires that keep the entire system working. Over time, these wires may become loose and lose their connection, and this can cause your circuit breaker to trip from time to time.  

An AC pro will fix this by re-wiring your circuit and may also need to replace the metal plate that contains all of your wires.  The ac pro can provide a new one, or you can purchase one separately on Amazon at an affordable price!

Don’t Risk Your Investment by Running Your AC with a Tripped Breaker.

How much is your peace of mind worth to you? Think about it, if your AC breaker keeps tripping and shutting off because there’s an underlying issue with the system, not only are you dealing with a hothouse day in and day out, but when Summer comes around again – that’s a whole lot more money. 

The best thing you can do for yourself (and the environment) is to get a professional AC repair service as soon as possible to identify and fix any issues before they become chronic. 

You may be able to save yourself from suffering through another scorching summer this year by taking care of your air conditioner now!

Q: Every few hours—sometimes minutes!—my living room and one side of my kitchen lose electrical power. I’ll check the breaker panel and, sure enough, a circuit breaker has tripped…again. Should I call an electrician, or is there a simple DIY fix I can try first?

A: While it’s frustrating when a circuit breaker keeps tripping, they are important safety mechanisms. Designed to shut off the electrical current when something goes wrong, circuit breakers are one of the best ways of protecting a home from an electrical fire. “When a circuit breaker trips, typically it is because we use too much electricity, which causes it to overload and turn off,” says Christopher Haas, expert electrician and owner of Haas & Sons Electric in Millersville, Maryland. For those who need an electrical panels 101 refresher course or aren’t sure how to reset circuit breakers, each breaker has an on/off switch and controls a separate electrical circuit in the home. When a breaker trips, its switch automatically flips “off,” and it must be manually turned back on to restore electricity to the circuit. For those wondering, “Is it dangerous if a circuit breaker keeps tripping?” the answer is that it can be, depending on the source of the problem. An electrician can ultimately deal with the root issue, but a little sleuthing will reveal whether it’s something that’s easily remedied.

In many cases, the cause of a circuit breaking tripping is an overloaded circuit.

A circuit overloads when more electrical current is being drawn through the wires than they can handle, tripping the circuit breaker. If this happens, there may be a few additional signs:

  • Buzzing noises coming from outlets
  • Devices charging slowly
  • Electrical outlets not working
  • Flickering lights
  • Scorch marks on outlets and light switches

If a circuit breaker keeps tripping in one room, homeowners can test for circuit overload by turning off all the switches in the affected area and unplugging all appliances and devices. After the breaker is flipped back on, the devices can be turned back on one at a time, with homeowners waiting a few minutes in between to see if the circuit remains on. If the breaker trips before all the appliances are turned on, the experiment can be repeated, this time turning them on in a different order. It may be necessary to do this several times to find out how many appliances can be operated at once before the circuit overloads.

“As a short-term solution, you can unplug unnecessary appliances to prevent tripping circuit breakers. You may still get some trips, but you can limit them by unplugging devices that you don’t need to use,” advises Dan Mock, vice president of operations at Mister Sparky , an electrical company with 90 locations in the U.S. The best long-term solution, however, is to pay an electrician for the cost to rewire the house and add additional circuits. The cost to replace an electrical panel is about $1,274 on average.

Other times, the issue may be caused by a short circuit.

A “short” circuit means that two wires that should not be coming into contact are inadvertently touching, triggering a sudden surge of electricity through the wires. A short can occur in an outlet, a switch, or within an appliance if wires are loose or have been chewed through by mice or pets. Some signs of a short circuit include:

  • Popping sounds
  • Discolored outlets or switches
  • Burning smells

Testing to see if an appliance has a short is similar to testing for an overloaded circuit. When an appliance that has a short in its wiring is turned on, it will immediately trip the circuit. Homeowners can also try plugging it into an outlet in a different room. If the breaker for that room trips, there’s a short in the appliance (if it’s unclear what breaker goes to what room, the breaker can be identified with one of the best circuit breaker finders ). Electrical shorts can be a major fire hazard, so it’s a good idea to call a licensed electrician for this circuit breaker repair. It’s wise to stop using the outlet or appliance until a pro takes care of the problem.

Another potential cause of a circuit breaker tripping is a ground fault.

A ground fault occurs when the electricity running through a home’s wiring diverts from the wiring loop and travels to the ground, usually due to faulty wiring or water infiltration in an outlet or switch box. Water is a conductor, which is why walking through puddles is often listed as something not to do in a power outage in case of downed power lines. Once water makes contact with wires, electricity can jump from the wiring loop and follow the water trail. This creates a surge in electricity leading to a tripped circuit breaker. If a person comes in contact with the electricity that is on its way to the ground, this can result in electrocution. Homeowners may notice a few signs of a ground fault, including:

  • Tripped GFCI (ground fault circuit interrupter) outlets;
  • A burning smell coming from an outlet; and
  • Lights flickering.

Newer electrical breakers have features designed to protect against the danger of ground faults. According to Haas, “Ground fault breakers sense electricity going to earth as opposed to going through the wires of the circuit. You’ll find [these] for bathrooms, kitchens, garages, exteriors, and basements.” GFCI outlets are another safety feature that shut off the electric current within a fraction of a second of sensing a ground fault.

If a ground fault is the problem, the cause of the errant water must be discovered and repaired, and any damaged wiring must also be replaced. It’s also a good idea to install GFCI outlets in rooms where water is commonly used. A GFCI outlet costs $210 on average.

Sometimes a bad or worn-out circuit breaker can be the culprit.

In some cases, the circuit breaker itself may be faulty. Breakers that are old, damaged, or were installed incorrectly may trip frequently for no apparent reason. Alternatively, faulty breakers may not trip when they are supposed to, leaving the home at risk of electrical fire. Some signs of a bad circuit breaker include:

  • The circuit breaker getting hot and tripping frequently;
  • The circuit breaker won’t reset;
  • It has been over 10 years since the breaker was last serviced; and
  • The breaker has scorch marks.

An important electrical safety tip to keep in mind is that resetting a breaker over and over again can cause what is called an arc flash, which is a small electrical explosion that can be deadly. If resetting the breaker once does not remedy the issue, it’s a good idea for the homeowner to hire an electrician near them who knows how to replace a circuit breaker safely. Mock warns, “Don’t take any chances with circuit breakers. Instead, call a licensed electrician who knows the safe ways to replace breaker boxes, upgrade circuits, and diagnose potential electrical problems in your home.” Wiring a breaker box is a job to leave to an experienced electrician.

A professional electrician can help determine the specific cause of a frequently tripping circuit breaker.

Most circuit breaker problems—aside from those explained in the sections above—will need to be inspected and addressed by a licensed electrician. According to the Electrical Safety Foundation International (ESFI) , each year “thousands of people in the United States are critically injured and electrocuted as a result of electrical fires, accidents, [or] electrocution in their own homes.” While homeowners may be tempted to save on electrician costs by attempting circuit breaker replacement or repair themselves, electrical work is not suitable for casual DIYers. “Yes, you have to pay, but you can save many hours of head-scratching by hiring an electrician. Electricians will also have all the right tools for diagnosing and repairing the circuit,” Haas adds. “Lastly, they will come with a warranty/guarantee should something arise, and they will typically return at no additional cost.”

Why My AC Keeps Tripping The Circuit Breaker?

Find out why your AC trips breaker after 5 minutes. Sandium offers expert aid when your AC conditioner trips. Visit us for help in time when your air conditioner trips.

Why My AC Keeps Tripping The Circuit Breaker?

The last thing you require on a hot Bay Area summer day is to have your AC keep shutting off because of a tripped breaker. There are several things that can cause an air conditioner to trip the circuit breaker repeatedly. The AC circuit breaker is responsible for shutting off the unit when an overload is detected. This in-built feature is meant to protect the equipment from fire and damage. The primary reason for an air conditioner to draw more amps is because it is running inefficiently or being overworked.

These are a few reasons why your air conditioner keeps tripping the circuit breaker.

Air Filter is Clogged

Airflow is restricted when a dirty air filter gets clogged because of dust and debris. The equipment needs to work harder for circulating conditioned air through the vents. Your AC will need to run longer for meeting the set thermostat temperature.

This will result in it drawing more electricity and causing the circuit breaker to trip. Dirty air filters also put an air conditioner through unnecessary additional strain making it overheat. The best way to correct this is by replacing or cleaning the air filter. Additionally, don’t ignore routine maintenance.

Low Refrigerant Levels

Refrigerant is needed to condition air. Air conditioners with low refrigerant levels will need to work longer for cooling a space. Older systems that have not been routinely maintained or neglected usually experience this problem. The refrigerant line develops holes that causes leaks.

The system will need to work longer for meeting the desired temperature as the refrigerant levels reduce in the system. You should not attempt to fix this problem on your own. Instead, you should get in touch with a professional AC contractor for repairing the leaks and charging the system properly.

Dirty Condenser Coil

There are two components in an air conditioning unit – indoor and outdoor. The outdoor unit disperses heat. It cannot perform its job when the condenser coils are dirty. This will again tax your system and make it overwork.

The air conditioner may draw too much power causing a tripped breaker. You should have your air conditioner maintained regularly to keep the condenser coil clean. It may be time you get in touch with an experienced professional if you haven’t had maintenance performed in a few months.

Motor Troubles

The motor in an AC has the potential to run for hours. However, when left running for extended periods, the wire insulation breaks down. This can result in an electrical short. A short can be described as a situation in which electricity bypasses the normal route. More electricity flows through the wires than they are meant to handle causing a fire. However, this occurs before the circuit breaker trips.

Compressor Doesn’t Start Properly

Compressors in older systems have a hard time starting. They pull more electricity which can cause a tripped breaker. You should ask a trained HVAC professional to install a hard start kit that provides an extra electrical jolt. This is a band-aid fix. If your compressor is too old, you may need to replace it.

Compressor is Grounded

This occurs when one of the compressor’s electrical windings break and hit the side of the unit. It results in a short to the ground. The short ignites the oil within the unit causing a burnout. The burnout can easily spread, tripping the breaker.

Portable AC Tripping Breaker? (10 Possible Causes & Fixes)

Upgraded Home Team

When the temperatures skyrocket in the summertime, the one appliance that works overtime is the AC . If your portable AC unit keeps tripping the breaker, you can do a few things before calling a service tech. The one thing you do not want to do is keep resetting the breaker if it continues to trip it.

The reason the breaker is designed to trip is to protect the appliances and all electrical equipment. It will also protect your home from burning down. So what are the causes, and what should you do if this keeps occurring?

Do You Need to Hire an Electrician?

ac trips breaker after 10 minutes

An air conditioner will trip mainly because there are more amps getting pulled y the breaker than what the breaker is rated for. So, if you have your portable AC pulling 30 amps on a 20 amp breaker, this will trip it. Don’t keep resetting it as you may cause a fire and harm your AC.

What Do You Do When the Breaker Trips?

These are the steps to follow if the breaker has only tripped one time.

Step 1: Turn off the Unit

Turn off the portable AC Unit from the power switch. Some only have the thermostat to turn it off.

Step 2: Reset the Breaker at the Breaker Box

Go to the breaker box and note the breaker will be in the middle of the ON and OFF switch. Flip the switch to the off position then to the on position.

Step 3: Wait 30 Minutes Then Turn AC On

You must wait for 30 minutes before turning the portable unit back on. This allows the internal circuit breaker of the unit to reset itself. When the 30 minutes is up, turn the AC back on to COOL.

Step 4: Wait and See

When the compressor is on, if the breaker does not trip, it was a power surge. If the breaker keeps tripping, then you will need to call an HVAC certified technician. If the breaker stays on for a time, then kicks off, then keep troubleshooting.

Power Surges Tripping the Breaker

When lightning strikes too close to the home, power lines, transformer, or anything electrical, power surges occur during a thunderstorm. It simply means too much electricity is overloading all of the circuits, and the power goes out. In some cases, it will trip the breaker one time, and it is okay to reset the breakers.

There is nothing anyone on earth can do to prevent power surges. It is something that happens from Mother Nature or even the power companies. If the breakers do not cut off in a power surge, the chances are high; the electrical components will burn.

If the Air Filter is Dirty, The Breaker Can Trip

When everyone talks about maintenance on any air condition, what is the one thing that is stressed? The air filter needs to be cleaned or changed regularly. This calls for once a month to keep the air flowing properly.

If the air is not flowing correctly, then the portable unit works overtime, drawing more amps. When this happens, the breaker will cut off, sparing the unit and the outlet. Once the filter is cleaned or changed, and the breaker stays on, you have solved the number one problem.

The Condenser Coils Are in Need of Cleaning

If the condenser coils are dirty, they can make the AC work overtime to keep the home cool. You can clean them with a vacuum cleaner hose with the brush attachment. There is a kitchen degreaser you can also use to take off the grime if there is some.

You can use spray bottles for the degreaser and use another for regular water to rinse off the coils. Once the coils are clean, try turning the breaker on again. If it kicks off after a while, continue troubleshooting.

For the rest of the steps, there is nothing more you can do. It will take a professional from here on out. Everything else deals with the electrical box or the components of the AC itself.

You will need to separate the two in the troubleshooting steps because it will take two services. One will be an electrician, and the other will be an HVAC service tech. You may get lucky and find one that can do both the box and the AC unit repair.

There May Be a Loose Wire Going to the Breaker

If there is a loose wire, faulty capacitor, or a short circuit in the wires, DO NOT ATTEMPT TO FIX THESE!!! Call a professional when it comes to the electric breaker box. If any of those things are the problem, it will trip the breaker every time.

An Overloaded Circuit Will Shut Off the Breaker

In these situations, the AC is not the problem. The breaker itself may not have enough amperage to cover the AC unit. If the AC is pulling 30 amps off a 20 amp fuse and breaker, it will trip the breaker.

The same applies to all appliances like refrigerators , microwaves, dishwashers, and other large appliances. When these appliances are running at total capacity, a lot can happen. Only an electrician can determine the cause and repair it.

Having a Faulty Fan Motor Can Trip the Breaker

We have covered everything an electrician can do for the breaker box. Now we move on to the HVAC services when the fan motor goes bad. There could be multiple reasons the fan motor goes bad, but usually, the only option is to replace it.

It is something that can strain the unit while pulling too many amps. These types of breakdowns all overload the circuit.

A Few Reasons The Evaporator Coils Are Frozen

These reasons below will freeze up the coils and strain the unit into pulling too much energy. The service tech will evaluate the situation and fix the problem. Afterward, if any of these are the problem, it should solve the breaker issue.

  • If the air filter is dirty, the coils will freeze up. (As mentioned earlier this you can fix yourself.)
  • The temperature outside may be too cool to run the AC. This will also cause ice on the coils.
  • If the system is low on refrigerant, the coils will freeze due to the strain. The breaker may trip if the unit is overworking.

If The Refrigerant is Low Much Can Occur

Refrigerant is like the blood that flows through the system to maintain the proper temperatures. If there is a leak, not only will the coils freeze up, but the portable AC will not blow cool. The number one cause for refrigerant leaks is due to corrosion on the coils from lack of maintenance.

It is also possible the system may be old and did its time. However, cracks and holes develop over time with these issues. If it is one or two leaks, it can be fixed.

The lines and coils will need to be replaced if there is more. Communication will occur if a complete replacement needs to happen. Since this also strains the unit, more energy than usual will cause the breaker to trip.

If the Compressor is Going Out There is Problems

The heart of the unit is the compressor. If this fails, not only will there be breaker problems, you may have to buy a new portable AC. The compressor is the component inside the AC that draws the most amps.

If the compressor strains to come on or go on and off, much power is drawn from the circuit. This would be a huge sign that is the cause of the breaker tripping. If you notice, most of these problems can be avoided by proper maintenance.

A Grounded Compressor Will Shut Down the Breaker

A grounded compressor means the electrical winding within the compressor is broken and has touched the compressor’s side. When this happens, it shorts out the circuit within the component, and it will automatically trip the breaker. Of all the problems, this is the worst.

For sure you will need a new compressor. If there is no more warranty, it is cheaper to buy a new unit.

On the hottest days of summer, the breaker trips. is there anything i can do to stop it.

It sounds like the AC is working overtime. Putting out box fans, keeping the shades closed to block the heat can help. Also, avoid going in and out as much as possible.So much cool air escapes each time the door is open.

What is the cost of energy burned on a portable AC unit?

The prices range from $.07 per hour to $.20 per hour. It also depends on how low the thermostat stays.

What are the safest temperatures to keep the inside of the home?

If you are looking to save money, summertime should be 78 degrees. When you are running the heat in the winter, 68 degrees is the best.

RV AC Trips Breaker After 5 Minutes: Causes and Solutions

Are you experiencing the frustrating issue of your RV AC tripping the breaker after just 5 minutes of operation?

Don’t worry, you’re not alone!

This common problem can be caused by various factors, from electrical issues to cooling system malfunctions.

In this comprehensive guide, we will explore the possible causes behind this problem and provide you with effective solutions to get your RV AC up and running smoothly again.

RV AC Trips Breaker After 5 Minutes: What’s Going On?

Before we delve into the reasons why your RV AC trips the breaker after a short period of time, let’s briefly understand what happens when a breaker trips.

A circuit breaker is designed to protect your electrical system from overheating and potential fires by shutting off the power supply when it detects an overload or a fault.

When your RV AC trips the breaker, it means that the electrical current flowing through the circuit has exceeded the breaker’s rated capacity, causing it to automatically shut off.

Now, let’s explore some common causes that could be triggering this frustrating issue:

Insufficient Power Supply

One possible reason for your RV AC tripping the breaker after 5 minutes is an inadequate power supply.

RV air conditioners require a significant amount of power to function properly.

If your RV is connected to a power source that cannot provide the necessary electrical capacity, the AC unit may overload the circuit and trip the breaker.

Additionally, using other power-hungry appliances simultaneously can exacerbate this problem.

Solution: Ensure that your RV is connected to a power source with the appropriate electrical capacity to support your AC unit. If you frequently encounter this issue while using multiple appliances, consider reducing the load by disconnecting non-essential devices or running the AC on its own dedicated circuit.

Faulty Breaker or Wiring

Another possibility is that the breaker itself is faulty or the wiring in your RV is not properly installed.

Over time, breakers can become worn out or damaged, leading to false tripping.

Similarly, loose or improperly connected wiring can cause electrical imbalances and trigger breaker trips.

Solution: Have a professional electrician inspect your RV’s electrical system to identify any faulty breakers or wiring issues. They can replace worn-out breakers or rectify any wiring problems, ensuring a safe and reliable power supply for your AC unit.

Overloaded AC Unit

An overloaded air conditioning unit can also be the culprit behind the breaker tripping issue.

If your AC is old or not properly maintained, it may draw excessive electrical current, exceeding the breaker’s capacity and causing it to trip.

Solution: Regularly maintain and service your RV AC unit to ensure it operates efficiently. Clean or replace air filters, inspect the condenser coils for dirt or debris, and check for any obstructions in the airflow. If the problem persists, consider upgrading to a more energy-efficient AC unit that matches your RV’s power requirements.

High Ambient Temperatures

Operating an RV AC in extremely hot ambient temperatures can push the unit to its limits, resulting in breaker trips.

When the outside temperature is scorching, the AC needs to work harder to cool the interior, leading to increased power consumption.

Solution: Take measures to reduce the ambient temperature inside your RV, such as parking in shaded areas, using window shades or reflective covers, and improving insulation. These steps can help alleviate the strain on your AC unit and reduce the likelihood of breaker trips.

Refrigerant Issues

Low refrigerant levels or leaks in the AC system can also contribute to frequent breaker trips.

Insufficient refrigerant can cause the compressor to overheat, leading to excessive power consumption and tripping the breaker.

Solution: If you suspect refrigerant issues, it is best to consult a professional HVAC technician who specializes in RV air conditioning systems. They can diagnose and repair any leaks, recharge the refrigerant, and ensure optimal performance of your AC unit.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions about RV AC breaker trips after 5 minutes:

Can a small generator cause the RV AC to trip the breaker?

Yes, using a small generator that cannot supply sufficient power can cause the AC unit to overload and trip the breaker. Ensure that your generator meets the AC unit’s power requirements.

Why does my RV AC only trip the breaker after a few minutes?

The most common reasons for this issue are insufficient power supply, faulty breakers or wiring, overloaded AC unit, high ambient temperatures, or refrigerant issues.

Can a dirty air filter cause the AC to trip the breaker?

Yes, a dirty air filter restricts airflow and puts additional strain on the AC unit, potentially leading to breaker trips. Regularly clean or replace the air filter as part of your maintenance routine.

Is it safe to keep resetting the breaker when it trips?

While resetting the breaker temporarily restores power, it is not a permanent solution. Continuously resetting the breaker without addressing the underlying issue can pose safety risks and may cause further damage to the electrical system.

How can I prevent my RV AC from tripping the breaker?

Ensure your RV is connected to a power source with sufficient capacity, keep the AC unit properly maintained, reduce the ambient temperature, and address any refrigerant issues with professional assistance.

Should I attempt to fix electrical issues in my RV myself?

It is strongly recommended to consult a qualified electrician or HVAC technician for any electrical or AC-related issues in your RV.

They have the expertise and knowledge to diagnose and resolve problems safely.

Experiencing your RV AC tripping the breaker after just 5 minutes can be both inconvenient and frustrating.

By understanding the potential causes and implementing the solutions mentioned in this guide, you can troubleshoot and resolve this issue effectively.

Remember to prioritize safety and consult professionals when needed.

Why Does My RV AC Breaker Keep Tripping & How to Solve It?

ac trips breaker after 10 minutes

Writen by Tom Hank

ac trips breaker after 10 minutes

Fact checked by Joseph Varney

why does my rv ac breaker keep tripping

An RV air conditioner that frequently turns off might require you to look at other areas other than the cooling unit. Sometimes, the suspect to this problem is the RV circuit breaker keeps tripping. Now you’re wondering “why does my RV AC breaker keep tripping?”

The reasons why an RV air conditioner trips breaker varies for each camping vehicle. It could be a short circuit, weak circuit, or overloading of the switch. Keep reading to know more details about each of these potential causes.

Table of Contents

What Causes an RV AC Breaker to Trip Repeatedly?

rv-air-conditioner-trips-breaker

If an RV AC keeps tripping the breaker, the main suspect can come from different sources. These problem areas include:

Short Circuit

Sometimes connected wiring can become damaged from other DIY projects for your RV. For example, you drill a hole in your camper’s wall and hit a wire that connects the circuit breaker to the AC.

For that scenario, the wiring will have a short circuit, causing the camper air conditioner tripping breaker. Replacing the faulty wire and securing the connection may help solve this issue.

Weak Circuit

Circuit breakers can degrade over time. For example, you have a 20-Amp breaker that brought you good service for many years. However, turning on the RV air conditioner keeps tripping breaker.

It’s because the switch can now only handle 30% to 50% of its original capacity. Swapping the old circuit breaker with a new model should restore optimal function to the cooling system.

Overloading the Circuit

For example, if the circuit is rated at 20 Amps, it will generally function well at about 80% of its maximum load. The switch will automatically trip or shut off the electrical load that goes over that mark to save the RV AC and other appliances from damages.

Take note that RV circuit breakers can run at a 20-Amp load, albeit during a reasonably short period. At this point, you have two options: (1) Reduce electronics usage or (2) upgrade to a high-load circuit like a 30 or 50-amp variant.

You may also watch the video below for a further explanation of these causes:

How Do You Stop Your RV AC From Tripping the Breaker?

The solution to the problem of camper AC keeps tripping breaker depends on the source of the issue. For example, if faulty wiring is the cause, fixing the connection from the switch to the AC can solve the problem.

However, if troubleshooting the circuit breaker yielded no satisfactory results, the problem could be your RV’s air conditioner.

Inspect the appliance to see if it has issues like a malfunctioning part. If it does, you may need to bring the cooling unit to a certified technician. Otherwise, prepare to spend money to purchase a new AC for your RV.

What Are the Signs of a Bad RV Breaker?

A bad RV circuit breaker may affect different devices in the vehicle, including the lighting, refrigerator, and other appliances. Some of the signs that point to a bad breaker switch are:

  • Flickering lights in the RV
  • Poor performances with connected electronics
  • Appliances turning on and off without human intervention
  • Burning or foul odor from the breaker panel
  • Frequent circuit breaker trips

If you experience one or more of these events happening in your RV, consider upgrading the vehicle’s electricity service panel. Doing so can increase the board’s circuit capacity, along with improving its safety features.

Where Is the Breaker Box in an RV?

The breaker box is usually near the fridge, the bed, or a cupboard. You may also find the panel on the wall.

How Do You Change an RV AC Breaker That Keeps Tripping?

camper-ac-keeps-tripping-breaker

Before proceeding, make sure that you know what you are about to do. You should be confident about doing the following steps. Otherwise, consult the expert help of a licensed technician to avoid costly mishaps.

  • Step 1: Find the source of the problem that is causing the circuit breaker to trip.
  • Step 2: Turn off the main power from your RV and on the main breaker panel.
  • Step 3: Remove the front plate of the panel by unscrewing the attached screws. Take note that the plate should be removed from the bottom.
  • Step 4: Push the faulty circuit breaker down and pull it out of the panel.
  • Step 5: Remove the screw in the malfunctioning switch using a flathead screwdriver.
  • Step 6: Take the circuit breaker to the hardware store and buy an exact model. Don’t use another type of switch if you already have the correct breaker size.
  • Step 7: Locate the screw in the new circuit breaker.
  • Step 8: Take the wires from the panel and slide them into the new switch. Secure the connection by screwing it with the flathead screwdriver.
  • Step 9: Push the bottom of the new circuit breaker into the panel. Once the bottom clicks, push it up and the switch should be attached properly.
  • Step 10: Put the metal plate back in place.
  • Step 11: Turn on the main breaker and test the connections.

Keep in mind that the inside of a circuit breaker panel is usually quite dark. Use a flashlight to shine a light on the parts to ensure you are working with the correct components.

You can also watch the video below for a visual representation of the steps mentioned above.

How to Troubleshoot an RV Air Conditioner?

If you deduce that the problem is not with your RV’s breaker panel but with the AC, here are some tips to help you find the cooling unit’s main issue:

  • Check the capacitors if the AC compressor has difficulty starting. The capacitor may be using too much electricity; in this case, replace it.
  • Check other connected appliances to check if adequate power is being supplied by the breaker panel.
  • Open the RV AC to investigate any shorts in the motor.
  • Do not repair a malfunctioning RV AC compressor but replace it.
  • If ice is building up in the AC, the appliance might be low on Freon. This leads the AC to use more power, causing the breaker to trip.
  • The AC’s coils are dirty if condensed water drips from an unusual location.

Why does my RV ac breaker keep tripping? An RV AC breaker can trip because of different issues, such as circuit overloads, short circuits, or faulty switches. You should troubleshoot your RV’s circuit breaker panel and the vehicle’s cooling system to check for damages. Some signs to look out for are:

  • Poor performance from the AC
  • Other appliances malfunctioning
  • A burnt stench coming from the air conditioner or breaker panel
