Question about Sharp R-1870 Convection/Microwave Oven
We have a Sharp R1870 microwave/convection oven. While baking today, it turned itself off. The blower still worked, and it produced heat, but everytime I restarted it, it would turn itself off (lights, timer, turntable, etc.) after about a minute.
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.
We have the applicable service manuals for these models and have uploaded it to our site here and here to help you. You will need the free Adobe Reader to view or print it.
If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
