I have a dometic ac with remote in our 2005 Keystone Zeppelin z261. We are camping in 95 degree Florida. While taking a nap, the ac remote quit working with the unit running wide open cold. I changed batteries in the remote, no change. The control panel on the unit itself showed the green light for cold, but the control did not respond. Turning off the main breaker made the unit turn off, reseting the breaker made the ac come back on. When I unplugged the modular cord connecting the control panel, the ac turned off, plugged it back in, now the unit will not do anything, is there a fuse somewhere, is the thermostat dead? What can I do to get ac for the rest of this trip?

SOURCE: furnace won't turn on, off, with or without remote

We hotwired the thermostat wires and the furnace started. That told us that the problem was with the thermostat. We took our remote control to another camper like ours and our remote worked their furnace. That told us that the problem was in the ceiling control for the furnace/ac. But the man who owned the other camper told us that he had a problem, too, and was told to unplug all the electric including the battery, wait 2 minutes, and hook up again. This might reprogram the circuitboard, and voila! It worked.

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

SOURCE: air conditioner will trip breaker when trying to cycle back on

The compressor motor , once warm is grounding out due to wear and is going bad.Have the compressor replace while it is still clean is cheeper and easier that doing it after a burn out,which  will eventually happen,if the compressor is tripping the brreaker as I suspect..

SOURCE: 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.
