Sam--the contoller board has a hardwired LC6041 chip.

Looks like a Sanyo uP. Can't find its datasheet, though. :-(

My spare parts
microwave has the same chip and it works. Ever tried to unsolder a 48
pin LC without damaging it thru overheating?

Many times. TV and VCR uPs are of this type. Just use a variable
temperature iron and a solder sucker with strong suction, eg a
Soldapullt. I re-tin all the pins before starting. Often you can
desolder two pins in one go if you bridge them with solder beforehand.

Harry--this unit has only one thermal cutoff switch physically mounted
on the casing surrounding the magnetron--electrically it is upstream of
all loads and were it to activate it would shutdown everything (lights,
fans, control display.. etc)--which is not the case here. Thoughts?
Thanks for all comments--
