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

by Cory
(Louisiana)

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.

A/C Tripps the breaker
by: James FTRVR

I just finished installing the new a/c unit on the roof. Total time including taking a lot of rest breaks because it's already got out, was 2 hrs and 20 minutes. At least half that was rest breaks, probably more. The hardest part was getting it up on the roof. Ok I left the old one up there for my son to deal with. I'm getting to darn old to work that hard twice in a day.lol. Seem to have fixed the problem. More than likely was the compressor going out. Good lock all. I recommend having help with moving the units up and down from the roof.

I am having the same problem with my a/c tripping the breaker. I just bought a new unit and I'm going to install it today. Hope this fixes it. The old unit is 8 1/2 years old.

Our air conditioner will run fine all night and during the mornings. Seems once it warms up outside the 20 amp breaker will trip. Thoughts????

Rv AC trip
by: Herman

I have the same problem with my 30/20 amp breaker. If my water heater is on, it will pop the ac breaker and then it takes a while to get it back on. Make sure your not running the microwave either.Wish I could convert from 30 amp to 60 amp panel.

Icing and.voltage
by: Anonymous

I will bet that the campground has a voltage regulating problem. We got a voltage monitor and found that in the campground voltage varies from 120 to 105. When the voltage is lower we are more likely to ice up.

Same problem
by: Anonymous

I have the same problem with my AC. I have taken it to the shop and it runs fine, bring it to the campsite and it’s tripping the switch every 5 minutes although if it’s just on "fan" it runs fine

ac keeps trippping
by: Anonymous

Try setting the AC back to 20 degrees. If we have it set to come on too cold it trips our breaker... so far this trick is working.

Ac tripping the rv switch
by: Anonymous

Ok, what happens when you take the rv to a service place and after several hours of the ac not turning off because they are testing it in their garage, the repair shop tells you there's nothing wrong with your ac but when you get to the rv camp and park under the sun the ac starts tripping the switch again. What do you do then?
