Hello,

Have a Panasonic Inverter microwave model number NN-SD997S. This unit is
just over 36 months old and has been used heavily without issue. This
evening just after the start button was pressed, the internal light
flashed blue and did not light, along with no turntable operation or
cooling fan operation. It looks like the magnetron ran for about 2
minutes w/o me really knowing because the meal was hot afterwards. There
was a bit of a 'hot steel' smell afterwards.......so fanless magnetron
cannot be too good either. Assuming i didn't damage it further with the
fanless operation.....what could be the issue with this unit and is it
fixable. This is/was a topline unit but bought at half price, roughly
225.00$. If it's an internal fuse, there must be major issues for it to
trip? Wall outlet is ok, checked with Fluke.

Thx for any info.

Maybe the "blue flash" from the internal light, was the bulb failing, and it
took out an internal fuse that feeds the lamp, fan and turntable supplies.
Ordinary lightbulbs often fail with a spectacular lightning storm inside
these days, and take the household lighting circuit trip with them. A bit
naughty if the Pan doesn't have secondary protection fed from this supply,
to ensure that the mag can't run with no cooling, or the food rotated in the
waves though. I'm sure that someone on here will be familiar with the model,
and know the answer ...
