    I have the same problem and have even called Sharp to see if they had had a recall or any other complaints for the same problem. The answer was no. It is interesting to hear someone else has this same weird problem with their microwave.

    I have the same problem joekochis's has with his Sharp model R1870. When I click where it says to click here for see manual it shuts the system down. I don't want to order a switch until I can check whether I can find the switch and how to install it. Thanks.

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.

59 Second shut off


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 (on the right side in your model) that opens or closes depending on cooking mode. If the controller thinks that the door is not in the right position, it will shut down the cook cycle in 59 seconds.

See the attached sample photo.
