Hmmm...let's see. New Controller board...$185 - $275.
New microwave...$89 That's a no-brainer....unless you guys know of more reasonable pricing for parts. Thanks, Craig "Jerry Greenberg" wrote in message om... 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. Jerry Greenberg -- "Craig" wrote in message ... Would anyone happen to have a schematic for a Sharp R7380 microwave? The keypad would intermittently ignore a key or two, and then recently it 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 a couple zener diodes and caps. Any help would be most appreciated. Thanks, Craig Manufacturer: Sharp Model Number: R7380 Numbers on controller board: H14A 94V-0, FA112DR |
