My problem is it stop working when I returned from a 3 day absence and saw the Microwave door (light) had been left open, i closed the door and the entire touch contol panel display went out and never returned. I verifier the usual, breaker, power surge (unplug and replug power cord) but no result.
I Have no blue print of the interior of this oven and don't know where to start. Fuse location? testing 120V primary and secondary power?

If and when i get good at this i also have another question concerning the over the range lamp that stop working 2 years ago. (not the buld, i'v tryed that).

I had Camco, repare man come and change what i found out later to be the thermostat, and that cost me 215$ for a 40min visit. Not again.
