Question about Sharp R-1870 Convection/Microwave Oven

1 Answer

Our microwave/convecton turns itself off after about a minute

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.

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.

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.

Sharp microwave r1870 only runs for 59 seconds


If it consistently runs for exactly 59 seconds, and shuts off, it's probably the control panel.

If it runs approximately that length of time, you might have a defective thermal protector on the magnetron, or the magnetron is running too warm for some reason.

I have a sharp over the range convection microwave modelr-1874F The convection works but the microwave sounds like it working, the turntable turns but it does not heat the food we tried unplugging it for...


Every time the microwave part of an oven do not heat it normaly means a faulty MAGNETRON (the device that produces microwves) unfortunately if it's the magnetron they are allmost as expensive as the oven it self, you could allways check for a burned fuse, (allways be prudent opening an applyance)

Good luck!

This is a problem in one of the damper-related components, either the switch or motor or the damper door may be binding.

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.
