My home AC is not working compressor noisy and condenser fan is not coming on?

Question

I thought it might be the capacitor at first, I have two units luxaire split system so I did a component swap of both capacitors. caps from non working unit worked on the working unit and caps from the working unit did not work on the non working unit. I suspected freon, but why wouldn't the condenser fan work?

Answer 1

Bad motor!swap good motor and cap. and see what happens.And the compressor is noisy because no air flow

thru condenser coil.

Answer 2

HVAC Tech.: The fan will not come on due to a burnt winding. If you don't turn the unit OFF the Compressor will burn out next. As you were slick enough to get away with changing out capacitors, maybe you could change out the fan motor. Take the old one out so it can be matched for size, hp,ccw/cw/shaft-size,and frame. Buy a new cap. to go with the new motor, they are matched to motor requirements.Good luck.
