Question about Heating & Cooling
Thats about all i can think of, im not sure how to test the capacitor, any help with that would be great..
To check capacitor, take it off and male a assembly with a 100W lamp in series with the capacittor, if the lamp turns on good, it means you have good chances that the capacitor is faily good condition
Or use this test circuit. Don´t forget security procedures!!

I had to get on the roof of mine, remove the cover and manually spin the fan. Add a little oil to the shaft where it goes thru the bearing. All of this is done on the roof side. Mine required this procedure every spring. Duotherm realizes they had a problem and have since corrected it but they don't deal with all of their customers that had the original problem.

First clean the condensor with air blower or water pump and clean the filters.If the same problem persists there is a choke up in the refrigeration piping, cut from the discharge side and suction side flush the system with nitrogen, replace the filter drier and choked capillary if it is a capillary system, brace back the discharge and suction piping to the compressor again, leak test with nitrogen, evacuate the system charge refrigerant and start the system.

High amp draw can be caused by a few different things, so first check that incoming voltage to trailer is sufficient. (115 volts) Not unusual for some parks to install more hydro hook-ups on a feed line, and when all are up and running, your incoming voltage could be decreased. If your o.k. that way, then I'd start looking at the compressor circuit of your ac, in particular, the compressor start-up capacitor. The capacitor basically stores electricity and boosts it to higher voltage for compressor and fan start-ups to reduce current draw that will trip the breaker. Please have a knowledgeable electrician, or RV tech check this for you, as a capacitor can give a real good high voltage (possible fatal) shock, even when power is off to unit. I also suspect that the start relay has shorted (welded) itself due to high amp draw situation, and that is reason it comes on by itself.
