SOURCE: Breaker keeps tripping

Your compressor could be going bad. You would need to check to amp draw on the the leads coming out of the compressor. There is a maximum rating listed on data plate. Something simple could be that your condenser the out side part of the unit is dirty. All you have to do is turn off the shut off switch out side, get a hose and some dish soap and wash the coils. Be careful with the water presssure not to bend the fins. Or some thing even a lot of techs look over is the breaker is bad.

The compressor motor , once warm is grounding out due to wear and is going bad.Have the compressor replace while it is still clean is cheeper and easier that doing it after a burn out,which  will eventually happen,if the compressor is tripping the brreaker as I suspect..

SOURCE: air conditioner keeps tripping breaker

Every air conditioner has a motor called a compressor. The compressor provides the cooling capacity for the air conditioner. If the compressor or its electrical controls are defective the compressor may try to start, fail, and create an electrical overload. If the unit does create an overload, every compressor circuit is also equipped with an overload safety switch. The safety switch is designed to protect the compressor from burning out. The safety switch will cut the power to the compressor for a certain length of time and then reset itself. When it resets it will allow the electricity to flow to the compressor once again. If the compressor then starts, the unit should function normally. If the compressor doesn't start when the overload resets, the overload will again cut the electricity to the compressor. This cycle will continue indefinitely. (Always allow three to five minutes before restarting the compressor.) If this situation is occurring, unplug the air conditioner and get help from a qualified repair technician. This problem is often fatal to the air conditioner because the cost of repair often exceeds the price of a new air conditioner.

if this helps please vote me a fix ya

SOURCE: RV ROOF TOP AIR CONDITIONER TRIPS BREAKER

Possible low voltage condition would cause that kind of a problem. To small a cord without the ability to carry and maintain the voltage would cause a voltage drop. I would test the voltage supply and make sure it is within 10% of that required for your A/C to operate properly.

Could this keep the air conditioner running and trip the breaker


Air conditioner may draw high current. It may trip the cirucuit breaker. You may check the current rating of the air conditioner. If it is higher than the circuit breaker rating, it surely will trip. If it is close but lower, it may trip as there may be other appliances connected.

Breaker keeps tripping on outside air conditioner unit


The compressor is probably drawing to many amps. Breaker could be weak also.. Need to check the amp draw on the compressor.

If the breaker is hot when it blows, the compressor is probably going bad.

Breaker keeps tripping after several hours of runtime. System has 40 amp breaker & is only drawing 31 amps.


electric motors (when they start to break-down) will run normally for hours (and read amps within the tolerance level).

Then after a long run time - the amps will 'spike' and trip the breaker.

This is a fairly common occurance - although there are other things that can cause a similar problem (though less likely), i.e. a dirty condenser coil, an improperly charged unit - or a bad breaker.

Bottom line. I think you need a Service Tech to take a look at the AC.

hope this helps

The furnace part of my central air is wired to a seperate breaker but keeps tripping the breaker and making a spark in the breaker box.


Usually a Central Unit is wired seperate, the Air handler inside and the
Cooling unit outside. It appears that the breaker is bad, is it a Single Pole Breaker?

Another possibility is that the indoor blower motor might be bad.

Hi there i have a toshiba single phase split system that keeps tripping the breaker after about a week of running i have checked the pressures the running current the fans an the coils an eveything is...


Check and see if it is correct size breaker. The breaker may be weak. If your amp draw is ok and the units starts ok. You may have a loose connection on the breaker or a bad breaker they do get weak over time. On the outside unit there will the correst breaker size min and max on the nameplate. Keep in touch Rus.

When turning on central air, our main electrical breaker is tripping. This is a brand new home barely over 1 year old. Should the AC have a warranty not covered by a builders contract??


Builders give a one year warranty but your air conditioner has five years on all parts. Anything outside the unit is not covered under the ac warranty. Breakers,stopped up drain and dirty coils.
