The motor doesn't start only hums. I changed the timer but is the same problem. If I connect the motor directly, it works perfectly. Do you think is the Switch or the Main Drive Motor?
Answer Hello Matt,
This sounds like a common problem this design gets. The unit could have lost electrical connection to the motor capacitor or it could be getting 120Vac from two sources at the same time. The second can be caused by several components which you will have to test for. If you start with the unit in spin and the connector disconnected from the motor, test from ground to each terminal for ac voltage. If there is 120Vac on more than one terminal, one of those wires will lead you back to the problem. It can be the timer or the wiring harness.
