Question about Dometic Rooftop RV Air Conditioner
Need wiring instructions for capacitor to the ac fan motor. Previous owner straight wired to avoid replacing a bad part, now I don't know how to rewire the Fan correctly.
Fan has three speed but I only use two for the AC. Fan wires, White and Brown Power, Red Low, Yellow Medium, Black High: the capacitor has Power supply, HERM (compressor) has three posts, and Fan only has two connectors.
I think the Brown fan wire should be wired with Herm, so it only runs when the AC is running, and the Red / Black (Low/High) should be conected to Fan terminals. Help, it's getting hot here.
You almost have it Look closer at the run capacitor. It has Herm, this is for the compressor, Com or C and F or Fan.
1 of your power wires is the fan speed so connect them accordingly usually black is hi, blue med, & red is low. You are "feeding" voltage to the selector switch on 1 side and coming out to the fan motor speeds.
Next you have a "Common" wire on your fan motor (this means its Common to all the other connections inside the fan motor to me. It is usually white. Connect this to the other line of power usually the Com on the capacitor unless it connects to a strip on the selector switch. But 1 of these 2 places will be the other side of your Power when plugged in. Lastly the brown it is usually the fan capicator only wire and it will connect to the fan "F" terminal on the capicator this terminal will not have any other wires connected to it.
This should make you a happy camper. Please rate me accordingly and good luck.
