OUCH! That hurts!

Actually most manufacturers will honor the warranty with the model & serial number, or if simply sign an affidavit stating when you purchased it.

You'll never know if you don't contact them.

It
may be the fuse, which is usually located behind the grille, on
the
floor of the oven behind the control panel, between the door switches,
or on the filter board near where the cord comes into the unit.




It will be a 15A or 20A ceramic fuse, either gray or white.



You should be able to
get one from a home center or local appliance parts store.


If
the fuse is good, it may be an open thermostat or thermal cutout (TCO)
/ thermal fuse on or near the magnetron or on top of the cavity / body
of the oven.


If it went dead almost
immediately after pressing the Start pad, that's usually a shorted
high-voltage capacitor.



If it went dead several seconds after pressing the Start pad, that's usually a failing
high-voltage transformer.



If
it goes dead or blows the breaker (or GFI) when you plug it in or open
or close
the door, then there's a problem with a door switch or door switch
mount.


If you need other parts, I would refer you back to the contact links in my solution above.

We're
