The microwave will not turn on unless the upper corners of the door are pressed to activate both door switches. A door spring was broken, as well as a bad bulb. I replaced both springs and the bulb, but the door, when closed, will still not activate the switches. Could you please provide a procedure to access the switch holder? Thanks, Jeff
Answer Hello Jeff,
Remove the two screws that go in from the top pointing toward the floor. Open the door and shift the air grille around until you manipulate it off of the unit. Remove the screw at the top, center of the control panel. Lift the control panel up and slip it off. There should be two screws in to left side which hold the switch assembly in position. You should be able to loosen these two screws and shift the assembly around a bit, even if it's one that has holes and not slots. If you cannot get enough adjustment from the slack, the switch holder assembly may have to be replaced.
Is there any way to test this control panel to see if it is reading the door switches properly?
Answer Hello Brian. The is no way of testing the control panel for the door switches. The best way to test the switches is testing the switches themselves. NC and COM should read closed and NO and Com should read open. This should change when the button on the switch is pressed. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
