Sounds a bit like an overheat situation. If the fan really is 120V
and not
speed controlled then I'd be looking for burnt wiring in the AC input
system.

However, I have a Panasonic doing much the same things. Pulled it
apart and
found the main MOV across the AC line was shooting flames out of the
top!
Then I noticed that the main power transistor (this is a inverter
machine)
has a big crack through the body. Only uWave I ever bought that
failed on
me.
