Question about Dometic Rooftop RV Air Conditioner

1 Answer

579 series, 13.5K BTU Rooftop trips AC circuit breaker in hot weather...

When circuit breaker is reset, the unit will run for 5-10 minutes, cooling nicely, and then trip the AC circuit breaker again. I changed the settings, but it did the same. After a half dozen or so tries, we just turned the fan on.

Once the outside temperature went down I tried it again. The AC worked fine all night and the next morning.

Dealer says if he can't replicated the problem, they'll consider it working. It does work, but not when the temp is 95 degrees.

Is your condensing unit located in a well ventilated area and have an ample space, atleast a foot, from the rooftop flooring? Just make a check that free flowing outside air properly ventilates the condensing unit specially on high ambient temperatures. Hope this would solve your problem

I have 2 15000 BTU A/C units run to a double pole 20 amp each breaker. The breaker keeps over heating and one side will trip. Should i separate the units on their own breaker? The units cool and run fine...


That would work, if for no other reason, to isolate which one may be drawing too much/more amperage. Keep in mind as well, after a breaker trips too many times, it usually will get weak and trip at lower amperage. If all is same, ( wiring from AC units) and units are cleaned regularily and no other internal problems such as weak, bad, capacitors etc, they should both draw same or close to same. If possible that someone has a multimeter with amp draw clamp, that would confirm where trouble is.

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.

Unit shuts off on hot days


It may be low on refrigerant. On hotter days, the compressor has to run longer to reach the temperature you have on your thermostat. Have it checked for the proper refrigerant charge and have them test how many amps that the compressor is pulluig as well. With the proper breaker installed, the unit should not be tripping out. Make sure that the breaker that is in there now is actually the proper one for your unit.

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.

Circuit Breaker and Dometic Rooftop RV Air


Its the watts you plug in too like ither 30 watts vs 50 watts. 30 watts will cause your wires to get hot in the unit. just pull down your breaker box and look at those white ground wires.
