I've found microwaves tend to have a high voltage diode, and a high voltage
capacitor. Both are known to go bad. I've repaired several microwave ovens,
and it's been these two parts.

This Jenn-Air (model M170B) 1,350 Watt microwave just stopped heating:

I called Jenn-Air customer support who said there's no troubleshooting for
when it doesn't heat. They said the magnetron may need to be replaced:

A replacement microwave oven has to fit over the electric oven:

Interestingly, (since it was above the oven) the back sticker says:
"May be built into a cabinet structure, but not for use adjacent
to (with 2 feet of) any gas or electric range, cooktop or oven."

But, that sticker also says:
This microwave is approved for mounting directly over Jenn-Air
wall ovens as follows:
W2700 Series Using MK271 Trim Kit, W3000 Series Using MK301 Trim Kit

Having never worked on a microwave, I ask what the conventional wisdom is.
Q: Is it generally feasible to replace just the magnetron?
Q: Will similarly sized microwave ovens fit (22" widex13"tallx15" deep)?
Q: Is it generally best to stick within the same brand? (e.g., JMC1116AB)?
