Breaker Trips on RV Air Conditioner

Question: What would cause my breaker to trip when using the air conditioner in my rv when it is very hot outside? I am in Arizona in an rv park with no shade. The air conditioner will only run for about five minutes when it is very hot outside before it trips the breaker. I can flip it back on and it comes back on, but will do the same thing. It does not trip the breaker when it has cooled down outside.



Robbie: The available voltage might be low during the peak hours of the day because everyone in the park is running their air conditioner. It returns back to normal when not as many air conditioners are running. It is a very common problem that happens in almost every RV park.

You can buy an inexpensive voltage meter that plugs into any outlet inside your RV that shows if you are receiving the proper voltage.

If you've been in the park for a long period of time, check the plug where you plug your RV in and make sure the prongs are clean and not burnt.

Finally, you could have a problem with your air conditioner for a few different reasons; it could be a compressor problem, start and/or run capacitor issue.

If your available voltage is good and your plug is clean, you should have a professional look at your air conditioner.

Weak Breaker Possible
by: Bud Corwin

Hi Robbie,

Just a quick comment on the article about the guy with the air conditioer problem. Your answer to him was true, but it is possible the problem could be either a weak breaker in his coach or the breaker at his pedestle. I had this same problem years ago in another coach. Once I replaced the breaker, the problem was solved.

Just my two cents worth.
