I first removed the top plate above the microwave door (3 screws), then I removed the plate containing the buttons and clock. The microwave has 3 relay switches and they are in a little holder. The holder was too difficult to remove so I just removed the bottom switch and replaced. The microwave started right up.
was told buy a repair person to check the door micro switches as it was a common problem. removed the top plastic air grill to get access to the screw that holds in place the control cover. After unplugging the unit, i took out the (2) screws that held in the switches and removed them (3). One switch was a bit melted so i tested it with a 12 volt battery and it was bad. Ordered a new one from Part select and got it fast . Works great .
After unplugging the unit remove the control face buy removing the screws. All three door switchs are on a bracket on the left. Remove the two screws holding the bracket in place and pull out. Disconnect the wires from the three switches and test each switch indivually to determine the bad one. I used a multimeter set on ohms.Replace the bad switch with the new one and replace all the wires. Reassemble the unit and you are good to go.
