Question about Dometic Rooftop RV Air Conditioner
I have a problem with my therm not working when unit is moved it sometimes loses power. Does not seem to have any control voltge going to it. I have power at unit. Where is the transformer for unit and what is the voltage sopposed to be.
If you turn electric off to unit, you can take thermostat off wall and inspect wiring. It sounds as if yo may have a short in the low voltage wiring. Each wire has to be totally secured. If there is nothing obvious make notation of where each wire goes to, then remove wires, there should be wires designated r g y twist these conductors together in a wire nut and then turn the breaker back on, if the unit runs properly you need to change out your thermostat. If it still has the same problem you may have a short in your thermostat wiring. If you have enough wire you can (turn electric off)cut back a couple inches and restrip the wire the way it was, and reattach to thermostat. The transformer is probably still good if it comes on sometimes. But you may need to check the other end of themostat wire, take off plastic shroud up above and trace where wire goes and inspect, reconnect if anything looks loose. Good luck and be safe, always de-energize to work on.
