• ** 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.

About 2 months ago, the fan would still run with the door open. Microwave was off, just fan running. Seemed to cook just fine. Thought maybe door switch stuck? However, a few times when I opened the door before cycle over (instead of pressing pause) the circuit would trip. I’ve always done this.

A week ago, microwave stopped working. Fan would run and timer would count down, but food not heating. I can hear that it is only the fan. I then played around with it, trying time cook, starting/pausing, opening closing door, etc, and it started working again after 5 minutes. Worked for a week and now it’s not, for about 5 days now. Not sure if it’s worth trying to replace switches. If I do, can this be done without removing microwave?

Thanks!!
Dave

The 3 door microswitches and possibly the switch holder need to be replaced to make your MW oven work properly. Removing the grill at the top first, followed by the control panel will give you access to the microswitches. Sometimes if there's a groove worn into the switch holder caused by the 2 spring loaded "fingers" on the door, that will have to be replaced also. W10727360 is a universal switch that is inexpensive and readily available.
