• ** 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.

My light under the whirlpool microwave went out and the bulb was broken so I had to remove the base with pliers. However I forgot to turn it off first and the electricity at the socket popped. I replaced the bulb and socket but the light still doesn’t work. I think there may be a fuse somewhere but don’t know enough to locate it. I am attaching a photo of the back of the control panel. Is there a fuse or something else to replace? It looks like this semiconductor in the 2nd pic has separated and has a little burn mark. Could that be the problem?

There isn't usually a separate fuse just for the light. The only internal fuse usually stops the whole appliance's operation, not just the light.

Unfortunately I do not have access to the unit's wring diagram. If you can post a clear picture of the one from the machine, I might be able to suggest possibilities.
