Please use a heavy duty cord, and be sure all other appliances in rv turned off, like water htr.; refrigerator; the other a/c; etc. Then turn the a/c on again; check to find out if it starts and operates ok. If you do not have a cord, start the generator, then ac and check out the operation of the air conditioning unit. If it still fails to start and run correctly, you will need to do further test the compressor.
I would say that your compressor is the source of the tripping out problem. It sounds as if it is stuck internally, not being able to start. When a compressor is stuck, it pulls more than three times the amount of normal starting current, which is certainly more than enough to trip the breaker.
You can also Check electrical connections and check input voltage--it it's low--IE 108 volts AC it will trip the breaker--and the breaker might be getting weak too--after several trips---the internal heater inside the breaker weakens the breaker to the point--of complete failure to remain "reset" you can also try to oil the fan motor bearings and see if it makes a difference.

Duo Therm A/C (2009 Sabre RV) won't shut off


bad compressor relay on control board. The relay is not opening the circuit, allowing the compressor to stay running when unit is turned off. This overheats the compressor and opens a thermal disk shutting the compressor off. When thermal disk cools down, the compressor restarts under load and trips breaker.

AC runs for 5 minutes and then circuit breaker


What else do you have running on hydro while AC is running? Such as coffee maker, microwave, water heater, fridge. That 30 amp breaker is your main breaker I assume, or breaker on pole your plugged in to. Keep in mind your AC will normally draw approx. 15-17+ amps momentarily when compressor kicks in to cool, then drop back to 12-15 amps when running normal. If your AC is drawing too much current, then you would only normally trip 20 amp breaker for AC in your panel. Try switching other appliances to gas operation while running AC, such as water heater, and fridge. Make sure incoming voltage is up to specs as well . (115-120 volts)
If water heater takes 5-8 amps, and fridge takes same when they are calling for power, you'll be close or over the 20amp mark when you consider your on board converter etc. as well. That only leaves approx 10 amps for AC that requires approx 15 amps to run, and up to 20amps when compressor kicks in. If you switch all those other items over to propane, and it still happens, then a current draw test should be done on AC unit to see if perhaps a capacitor is faulty, or possible compressor faulty.

Throwing breaker


Throwing the MAIN BREAKER should not happen. Calculate the distance to your main box. Tell me the wire gauge or breaker amperage. Whatever you do, do not get a larger breaker! If its a breaker on this unit Its probably doa with current leak possibly. DO NOT USE fire hazzard IF SHE TRIPS!!! let me know if its your main breaker inthe house. Hopefully you dont have crappy cloth wiring.

Ac Problems


You must have too many things running on that circuit. Check your connection to the power box.Loose connection on the receptacle can cause the breaker to trip or too many things running on the same circuit. If the breaker is old it might need to be replaced.

You probably have a dirty condenser coil or the con den ser fan motor is bad or the blades are jam that's why it overheat and shut off by overload.
