RV Repair: Air Conditioner, crossroads trailer, old crossroads

Question
The air conditioner on my 2yr old Crossroads Trailer keeps tripping and the air won't work continuously like it should.  Why does the breaker keep tripping?

Answer
Hi Pat:

I need to know which breaker you are talking about that is tripping? Is it the breaker that supplies incoming power to the RV, or is it one of the RV breakers, for example, the a/c breaker? What happens when you reset the breaker, and how long will it stay on before it trips again. What appliances are turned on in the RV? Does the air conditioner try to start?

Please respond, and I will get back to you as soon as possible. Have had lots of responses for assistance with this heat wave.
Regars, Larry
