We tried replacing the fuse last night. At first, there was nothing, but when my husband banged on the top, the control panel lit up. We pressed the button to start it, and the whole thing died. We repeated this a couple more times, but no luck, the microwave kept shorting out immediately. We replaced with a 15 amp fuse that matches the size of the original. Is there anything else we can try before giving up?

The most common suspect here is a shorted high voltage capacitor, since you say it blew the fuse right after Start, but I would certainly suggest checking the door switches and door switch mounts first. Just be sure you installed the right fuse. It would be a The switch mounts seem to break at about this point in the life of these models.

This
is a problem in one of the damper-related components, most likely the
switch, but it may also be the motor or the damper door.
The
damper is a door inside that opens or closes depending on cooking mode.
If the controller senses that the door is not in the right position, it
will shut down the cook cycle.
Sharp models stop after
59 seconds.
See the attached sample
photo for a typical damper assembly.
What is your model number? We may be able to point you to the full service manual too.
If a switch is all you
need, we offer a universal type for only $5 postpaid which you can

you may have some arching inside where your magnatron is located.If you open the door on the right middle part there is a silverplate on the wall .If it is burned you may need to replace magnatron.if you do not seee burn marks it may still be the magnatron hope.that would be the only possible thing that would make the noise other then the mtor plate out of place.
