OK, Art, here is a picture of the latch, the black 'push-in' part lifts the white plastic part and unlocks the door, plus breaks contact of the micro-switch so you don't get your brain fried from the microwaves when the door opens.
The latch fails in two ways, #1. the fix I made in the slide show years ago, well, I think it is backward, but anyway you can see what I did.I epoxied a brass electrical connector..it was the right size and sturdy.. to the broken plastic stem that goes through a hole on the other end. The black 'push to open' part hinges on the two stems. This worked for 3 years, then the plastic stem broke.
So, (#2) to repair that I drilled a small hole through the brass reinforcement epoxy deal and put a small bolt and nut. The small bolt goes through the hole to pivot the 'push to open'.
Sue was baking some chocolate fudge Volcano's and the latch broke, I hurried and took it apart so the food wouldn't overcook.
I didn't document the second bolt deal, I wanted to eat the volcano..
Hope this helps...
