Air Conditioner in RV Keeps Tripping the RV's Circuit Breaker

by Cory

AC keeps flipping my 20amp breaker in my travel trailer. I can put the fan on and its okay but when the compressor comes on it flips the breaker in a short time.

ANSWER: Greetings Cory thanks for submitting your question on our Ask An RV Question Page.

I am going to assume that this is a new problem and that prior to this the Air Conditioner was operating normally. I am also going to assume that you have not connected any new 120 volt electrical appliances to the circuit that the Air Conditioner is connected to.

If all of the above is true then there are several conditions that could be causing the problem you are experiencing. The most common causes of this problem are a bad compressor that is starting to draw too many amps on start up and/or while running, you could also have a bad start or run capacitor on the AC unit.

Unfortunately the problems I mentioned above are not do-it-yourselfer repair jobs. Your best bet is to take your Travel Trailer in and have the Air Conditioning checked out by a Certified RV Technician.

I hope this helps.
