Whirlpool Washer Motor Control Board

Whirlpool Washer Motor Control Board

The motor control board (MCU) on the Whirlpool washer provides power to the washer motor.  If the motor control board is bad, the washer may not agitate or spin.


The motor control unit (MCU) is often misdiagnosed as being faulty when quite often the problem is a bad wire connection between the circuit control board and the motor control unit (MCU).  It is possible they are not communicating between one another.  It may even be that the door lock has failed.

You can run some diagnostic tests on the washer using the tech sheet, it should be located behind the lower panel inside the washer’s compartment on the side wall.

It will help you to trouble shoot and isolate a faulty part or parts.
