For Frigidaire Control Board (Part Number: AP3891780)

Answer or Comment

All cycles work, except the final spin turns slow. I found out it has a motor board, after I replaced the motor. So, before I invest anther couple of hundred dollars I actually think that since the motor is receiving a signal from the control board to spin, that its not spinning fast because the motor board is not working proper. It has a good spin during the wash cycle. Any suggestions?

ANSWER Hello F.I., The motors on these actually don't fail that often. The motor control board 134743500 is the component that usually gives out on them, at least as often as electrical connections are dropped. If all of the connections are good, I would assume that the motor control is at fault. There are several circuits in there that send RPM information to the machine control and the spin voltage is in turn sent back to the motor.
