I would suggest that you visit an ac specialist shop as all air conditioners( car, truck , house and yours all use the same principle of operation
because it is roof mounted in an RV may be a caravan repair shop that has an ac specialist in the workshop or a truck service shop that installs ac units in truck cabins would be a good place to start
there is a fuse located under the shroud on the roof AC on a circuit board that controls the thermostat to turn on the power to the Air Conditioner replace it it is marked F-1 or, on some F-2 etc. the air conditioner works on both DC voltage for the thermostat and AC voltage for the compressor
If the Air comeing out is the same as the temp inside the RV make sure the compressor is running and not just the fans. It could be low on freon. If freon is ok then you would need to ck the wiring to the selector switch for a short. It would be obviouse because there will be melted wires. I am leaning toword low on freon since you have already been inside the wiring/control unit.
I see what you see also in the manual. The difference is the Heat Strip package that part is optional and the 600212-001 with the optional heat strips becomes the new 600315-001 I talked to Dometic Duo-Therm and the models are the same but they both are not heat pumps but the new heat strip package comes on when told to go into heat mode when you change the thermostat to heat. The part you purchased will fit both model numbers you listed for your roof top air conditioner. Thanks, Sea Breeze
Actually you should have fried you converter. What is the voltage reading you get for the air conitioner? supply? One should run off the generator and the other on shore powerIs it set up that way?.
check the compressor winding resistance from common to start
start to run
run to common
the two lowest should equil the highest
also check shorted to ground
check the capacitors the go bad a lot
