• ** 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.

Bosch Microwave HMC80251UC/01 No display

Our Bosch built-in microwave stopped working. The display doesn't turn on and the interior light also doesn't come on when the door is open. The buttons are not responsive. The breaker didn't trip. The display had come and gone from time to time before this.

From the reading I've done so far, it's probably a bad door switch and the fuse is blown. Or the control panel is dead. Any guide I can follow to find out which one it is?

The thing is mounted with a oven and I also have a hard time to pull either of them out of the cabinet. :(
