So the stupid thing all of a sudden quit doing anything. Wouldn't hum or run or heat, so I took it apart. I cleaned it all out and something I read said to see if the motor switch was stuck open so I unscrewed the two screws holding it to the motor and the stupid thing fell apart. Wasn't sure how the wires and terminals went back in it. I thought I figured it out and I put it back together. Now when i push the start switch the motor hums but the drum won't spin. I disconnected the drub and belt and pushed the start button and the motor spins. However, When I let go of the start button it stops. Any clues? Thanks in advance.
