Hi, Not sure if this is a common issue with an easy fix or something else. Last year I noticed my A/C isn't working. We generally camp in higher elevations so it wasn't a big deal, but I definitely need to repair it. The fan works, but when the A/C condenser kicks on it will trip a breaker if plugged in or overload the generator when it is being used. I've read other posts regarding the coils being dirty and I'll check that (I'm sure they are), but I'm reading that with dirty coils they trip the breaker after running for several minutes. Mine trips the breaker immediately, which leads me to believe the motor is probably bad. Thanks

I'm assuming in the past the A/C worked fine when you had the generator running. If that is the case it could be one of several problems. Breakers do go bad and trip easily so it's possible that is the problem.If it's not the breaker the more common cause is something in the A/C unit. You'll need to have it checked out by an A/C technician to determine the cause.I'm guessing (I'm no expert) it's the starting capacitor that's bad.

Yes, it has always ran fine on house power and on the generator. I first noticed the problem when I had it plugged into the house to charge battery and cool the refrigerator before a trip. My wife turned it on to cool it down for cleaning and it tripped the breaker (115V) in the garage that I use for welding (25 amp).I plan to get it out of storage to have the tires replaced in the next week or two. I'll get up there and look it over then. Just wondering where to start looking.

+1 on checking the start capacitor.Is it the 20a branch circuit, 30a main or the pedestal that trips?

It ran fine on the pedestal in a couple camp grounds we used early in the season last year. About mid season on it was all generator. It overloaded the generator on the last trip and the house circuit before that. It seems like a something failed instead of something gradually failing like dirty coils. I'll check the capacitor out when I get up there. Thanks for the input!

Could it be a bad started cap?
