Question about Sharp R-1874 Convection/Microwave Oven
On light on display, fuss is good
Are you saying it's dead, with no display and no inside light when you open the door? And the fuse is good?
If so, you may have a bad magnetron temperature fuse. This device looks similar to the attached photo and is located near where the magnetron mounts.
You can usually find exploded views entering your model number at the Sears parts site.

The most likely sources of the funny sound would be the high-voltage diode, transformer or the magnetron.
It's possible that the high-voltage capacitor shorted and blew the fuse.
It will take some troubleshooting.

There is a fuse located behind the control panel.
If that is good, or replacing it does not fix it, you may have a problem with the control panel, which we repair nationwide for $39.95.
