There's 2 screws on the blade side of the condenser fan motor housing. Remove the blade for better(I don't mean easier) access to the screws. You will need a short philips screwdriver. Get the kids out of the room because it's a rotten bastard of a motor to get out. Did you check the DC voltage to the fan motor at the motor connection? I just replaced a main board a few days ago that had proper voltage at the J2 plug but voltage dropped at the motor. I ended up taking that motor out and putting it back in. Good training.
SANTA: do you mean you thought you had a bad fan motor but it turns out it was the motherboard?
I just checked the wires closest to the fan motor:
But when I disconnect the fan motor wires:
Connect and disconnected from fan motor:
I didn't take the fan motor out.
I did connect the fan motor to the 9V battery and the fan spun fine!
Which part is the problem? Fan motor? Motherboard?
Is the motherboard install straight forward? It looks similar to installing a motherboard for a desktop computer. I've got my A+ certification if that helps. ))
