Kaseydog thank but that did not work.

Here’s a solution that Toymeister was nice enough to share with me this is based on the fact that the lights on the microwave still work.

The microwave, all microwaves, have three safety interlock switches to detect when the door is closed. The one which energized the "microwave" (magnatron) part of the unit has the most current passing through it. Usually this is the center one. They snap in/out. They use slide on spade clips. for power.

First remove the unit from the wall, remove the back and side screws that hold the cover on. Looking at the back of the unit pull the cover up on the rear and towards you. It is clipped in on the front. Where the locking mechanism for the handle is you will see three rectangular micro switches, each with two wires going to it. Replace the center one, try the other two if that is not the one

Notes if the cover screw are tamper resistant, by the tamper screw driver tips from harbor freight for six bucks or so
Here is the switch:
Damn can't link it here. On Amazon search for microwave micro switch. I usually use podboy brand or some such. They offer several brands,they are all the same. From 1.00 to 3.50 each, depends on quantity.
