Drum wont turn.pust start and hear a buzz but drun wont turn

I have found that the switch activated by the door close or turns on the interior light when open on is likely the problem. You may notice that if the door is open and you push the start button, it will buzz. So if the door is closed and you get this buzz when pushing the start button, there is a problem with the door switch. The start button "thinks" the door is open, and therefore not start. The defective door switch needs to be replaced. At least highly likely.

Could have a bad motor or something stuck in the blower wheel.can you spin the drum by hand?if so most likely the motor.try this open the door,hold the door switch in with one hand,spin the drum with the other and have someone else hit the start button,if it runs you have a bad motor.by helping it along it sometimes will run but the motor is still bad and it will buzz again.
