A little 3 ton unit. 460 volt. The condenser fan is running all the time and the contactor is not pulled in, I pick the fan shroud up and fan goes off. The compressor is 3 phase and has a double pole contactor. Reading 17 volts on the motor leads to fan motor that is running. 277 to ground on both fan motor leads. I believe fan motor is going to ground and running on the voltage coming through the 3 phase compressor as the fan motor is single phase. I am replacing the fan motor tommorow. Fan runs just fine also when the compressor contactor pulls in. I thought I should go to selling fries at McDonalds after this one.
