SOURCE: Ruud heat pump outside unit trips circuit breaker

Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.

SOURCE: my ac circuit breaker keep tripping

If your outside condenser has a locked rotor or short circuit, than the unit WILL trip the breaker - as it should. On the other hand if a breaker is tripped a few times it will have less of a capacity that the rating, (this is designed in it). You will need to determine if the unit is locked (and broken) or the breaker has become too sensitive.

SOURCE: Electric Furnace Trips Breakers

it is normal for a breaker that is run right on the edge (50 amp and your furnance to use 45) to get weak after a while . the first thing you should do is change the breaker with the same type and amp rateing . it should take care if it

SOURCE: tripping circuit breaker

Replace the start/run capacitor and try it again. If that does not correct the problem you have a bad compressor.

SOURCE: air conditioner will trip breaker when trying to cycle back on

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..

Dryer trips breaker after only a few mins of operation


Check to power at outlet for 220 volts

Check the breaker for the correct amperage cut off.

If the unit had an obstruction in the air flow, it would not trip the breaker.

Try running the unit with just cool air and see if it trips the breaker.

Odds are, you have a defective breaker.
Also, if the home is newly built, check the panel for loose connections at the breaker.
Or you could try a different power outlet, like the hot water heater.

If the unit continues to trip breakers on other outlets, you may have a short in unit.

Rv airconditioner trips breaker


Does it trip when fan only , or when compressor for cool cuts in? Sounds like capacitor perhaps . Get back to me with model number, and whether it's a ducted system, or blows out at ceiling assembly.

Why does my compressor trip the breaker after filling with air


1 of 2 things #1 the pressure releive valve that lets the pressure of the pump when it kicks off is stuck closed so what is happening is when the compressor kicks back on its under a load and trips braker. #2 your braker is to small for the compressor.

MY DOMETIC RUNS ALL DAY THEN IT BLOWS A BRAKER ONCE A DAY, WHATS THE PROBLEM ? BLOWS COLD AIR


Depending on how hot it is outside, there may not be a problem. It might just be running all day to try to keep up with the amount of heat that's outside. It'll blow a breaker most likely because it's drawing so many amps through the circuit breaker that it trips.

When compressor kicks in the circuit breaker trips and shuts off juice to outlet; when run in "fan" mode the circuit breaker does not trip. Am I doing something wrong? It was running at this...


This appears to be a direct short internally to the compressor . you neede a ohm meter to test it .. not certain how old the unit is but if its a window unit and over 6 years old I would buy a new one. But it does no0t sound good. In the future when a unit trips the breaker and you reset it and it trips right away its best not to trip it again as it contaminate the inside of thye system and is very difficult to clean and expensive as well . those are my thoughts. It could be the outside fan but the way you decribe it tripping right away my money is on the compressor

Usually trips breaker but occasionally works fine....when hooked to higher amp breaker line works fine.


it could have a small leak to ground on it,,, thats why it trips the brakers,, on a higher braker the leek off also needs to be higher than 50milly amps to trip the braker,,, this unit uses 13 amps

Unit shuts off on hot days


It may be low on refrigerant. On hotter days, the compressor has to run longer to reach the temperature you have on your thermostat. Have it checked for the proper refrigerant charge and have them test how many amps that the compressor is pulluig as well. With the proper breaker installed, the unit should not be tripping out. Make sure that the breaker that is in there now is actually the proper one for your unit.

You need to start with a basic inspection in the outside unit. For the breaker to trip immediately like that indicates a dead short. With the breaker OFF look at the internal wiring between the contactor relay and the compressor. You are looking for signs that the insulation may have been chewed by a rodent, or a wire is off of a terminal and in contact where it shouldn't be. If the wiring looks good, terminals pass tug test etc. you may have a shorted capacitor. Make sure to check the wiring for the fan too. You can disconnect the com lead for the compressor and fan one at a time to isolate the defective component if needed. Work safe! turn the breaker on for the test, and off again before you put your hand or tools back in.
