• ** 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.

Sears Kenmore
Age
6-10 years
When door is opened the light comes on and it runs, including plate turning. It stops again when door is closed. It does not run when trying to run it with door closed, although the light comes on and timer counts down.

Interestingly, at around the same time we noticed our Amana range was flashing F1. I posted that problem in that forum.

Thanks for any counsel!

Sorry, we must of missed your thread by accident.

Glad to hear the new lower door switch fixed it.(y)

Your Kenmore 721 model is made by LG.

Here's the lower door switch for your model, in case others need it too:

Thanks. This was the closest I found at the local hardware store and it worked fine.
