Whirlpool tech line say:
If the MCU does not slve the problem, replace the CCU, part # 8182695
Be sure to check the harness where it plugs into the motor, as the tachometer reading is not being processed at the CCU like it should. This translates into a potential motor problem, open harness someplace or a bad CCU. We know the MCU is working now.
Your motor leads can be tested from the MCU from the data in the tech sheet. There have been occasions where after the MCU and CCU have both been replaced, the harness also had to be ordered. Just tellin ya, it can happen...
