Order a new controler board, and key pad assy. If the parts are still
available, Sharp sells these as a replacement parts. It is very rare
and not cost effective to troubleshoot these boards at the component
level in the service departments. In many instances the descreat
components from Sharp may not be available. There are many
specialized devices on these boards. Sharp should also be able to
supply the service manual if it is still available.

Would anyone happen to have a schematic for a Sharp R7380 microwave?

The keypad would intermittently ignore a key or two, and then recently

stopped accepting input from almost all keys. I suspect the controller
board, and there do seem to be a couple of dark spots on the board near

couple zener diodes and caps. Any help would be most appreciated.


Manufacturer: Sharp
Model Number: R7380
Numbers on controller board: H14A 94V-0, FA112DR
