Question about Dometic Rooftop RV Air Conditioner
The click you hear is possibly the contactor switch on the unit. This swith is activated by the thermostat which in turn sends voltage to the compressor. First things first, You need to check the contactor swith to insure you are getting power from the switch on.. Activate the thermostat the contactor will activate you shoud get the same voltage reading from l-1 and l-2 as you get from the t-1 t-2 sides of the contactor. if these readings carry the same volts then your problem is towards the compressor. Next item to check is the capacitor. this is a round or oval shaped metal cylinder that has several wires going to it, Some of these capacitors are dual, in other words they run both compressor and condensator fan motor in one unit sometimes each peice , compressor, fan motor, has a seperate capacitors If it is a dual capacitor the will be 4 or more wires going to it. since these aren't as costly I would recommend that you replace the capacitor and see if that has cured your problem., If it hasn't then you are possibly looking at a bad compressor and an a/c tech would need to be called to check that for you. Good Luck
