Hey all:

We have a Whirlpool under counter, over stove microwave (vented

it quit again today. *My wife was replacing it and it popped, blew the
glass bulb out of the metal socket/base, and won't work anymore. *I
think that when she moved the bulb it shorted out inside the bulb

Anyone have any ideas? *Please and thanks, HDK

This isn't a recipe-type fix. Remove the microwave from its mounting
brackets, take it apart, and see what's going on. If the trouble isn't
obvious from a visual inspection, then hopefully you'll find a schematic
tucked inside the machine and you'll be able to troubleshoot it.- Hide quoted text -

If the bulb socket tends to be exposed to heat or fumes it may have
corroded and/or the internal threaded socket have twisted or shifted.
Realizing the the light bulb is probably just a switched 115 volt lamp
circuit; but be very careful if the rest of the microwave works while
you have any covers off.
There's 5000 volts DC on the magnetron inside and the possibility of
RF (microwave) leakage. So stand well back from any exposed 'works'.
If you are not an experienced microwave or radio transmitter
technician do not work on the microwave portion itself.
This is not to be negative; just careful!
Good luck with the repair.
