First, check the door switch. Push and release it by hand and you should hear a click. If no sound, replace the door switch with this part.
If the switch is ok, press the cancel button on the machine. Then do this. press and hold the start button for 2 seconds then release wait 2 seconds and press and hold again for 2 seconds continue this pattern until the dryer goes into test mode. You will see all the lights on the control light up. press each button on the control one at a time 3 times each. (Do not press the cancel button) until the dryer begins to run. When the dryer starts to run then press the cancel button. Then your machine should function properly.

assume the buzzing quit when you release the start button. Open the dryer door and slowly rotate the dryer drum in a counterclockwise (CCW) direction. Rotate the drum 2-3 revolutions and then shut the door and see if it will start. If it continues to just hum and not start could indicate a voltage issue, motor issue or a friction issue. Open the door again and locate the door switch plunger in the upper or lower corner on the hinge side of the drum opening. Hold the plunger in while someone begins rotating the drum counterclockwise. While turning the drum counter clockwise and holding the door switch plunger inwards press the start button. If it starts, there is likely a friction problem or motor problem.

Hi, this is a simple issue here. these switches will fail from time to time. the start switch is unable to hold the circuit, in return, opening it upon release of the button.

Simply replacing the switch will fix this issue. switch is 20 dollars tops.

this problem sounds like it can only be 1 of 2 problems. the start button or the motor is not going into run winding. i found over the years that the blue wire i believe is burnt at the motor. this can be repaired quite easily .cut the wire and strip it putting a new connector on. if you need to you can buy an assortment at a hardware store. if every thing is good check the start button for burnt wire if ok then you most likely have a bad motor. i'm pretty sure though that a wire is burnt off at the motor
