The microwave will happily begin to microwave a cup of water.
After about a minute or so, the fan and the turntable will stop.
The light stays on, and the counter keeps going.

What powers the stirrer and turntable? Do they have their own power supply
separate from everything else?

Does the magenetron continue to operate?

PS: Thanks for giving a clear description of what happened and what you
did.
Most people don't!



I've been seeing a lot of bad solder joints on the control boards in
microwaves lately. I think it's due to the switch to lead-free solder.
