Per trader_4:
Any idea why it cut out?

Nobody is owning up to seeing/doing anything unusual with the device.

OTOH, I found some baked-on something-or-other on the rotating glass
plate and the paper towel we usually have on the plate has been soaked
with something brown..... so my money is on somebody putting *something*
in there for some period of time that caused excessive heat.

We are currently blaming the cat.... -)
