hi,

Did you try replacin the fuse.It might have blown.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

where is the fuse at on the sharp grill 2 convection

Replace fuse with slo blow from Ace Hardware. Plugged unit in, clock worked. Turned unit on and immediately blew new fuse. Will fix it with a new unit.

Blown fuse in the back

Does this unit have a turntable? If so does it turn when on?

check high voltage transformer and high voltage diodes, condencer, and magnetron.,
