This video shows how to test a Whirlpool (or Maytag, Amana, Inglis) Duet style washer motor with the integrated MCU (Motor Control Unit.) The MCU used to be separate from the motor, but is now attached to the back of the motor. Testing is very much the same as when the MCU was a separate device, but I thought I would show testing on the newer style with the MCU attached.
WARNING!! This is a live test – that means that there is power (which can hurt you) and the belt, pulley and motor may spin (which can also put a world of hurt on you!) Be aware of what you are doing and where you are at while doing these tests. I accept no responsibility for any problems you encounter if you attempt to do this yourself. That being said – Enjoy!
