• ** REMEMBER! **The microwave can still shock you even unplugged!!

    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

Some times, but not most times, when we close the door after removing an item from the microwave the light stays on and the fan turns on. If we open and re-close the door the light and fan turns off. The Microwave is 3 years old and about 6 mos ago one of the upper door switches went bad and I replaced it. Would this new issue also be caused by another switch, or is it likely something else.

Thank you,
Hi Rick, I was unable to test the switches while mounted. I removed and tested all 3 of the switches and they all are working properly while disconnected and being tested. This has been an intermittent issue about one out of every 4-6 times we close the door.

After I reassembled the switches and mountings, the light/fan issue happened every time I closed the door. I removed and reinstalled the mountings and switches and I was very careful to make sure they were centered and perfectly seated in the mounting tabs. Since then, I've opened and closed the door more than a dozen times and the issue seems to have gone away.

I removed and tested all 3 of the switches and they all are working properly
The switches can be good and the door is not activating one of them. Glad to hear it's working now.
