Change the Damper Motor and switch. Cost is approx $30.00 and you must remove the microwave from the mounting bracket and remove the cover to gain access to the motor and switch.

Why does the microwave only run for 1 minute at a time on any setting?


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.

Sharp models stop after 59 seconds.

See the attached sample drawing for a typical damper assembly.

We have the applicable service manuals for these models and have uploaded them to our site here
and here
to help you.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

The microwave shuts off after 59 seconds. You can push the START button and it will start again but shut off after 59 seconds. The convection oven component does the same thing.

R-1874 shuts down after 59 seconds


That switch is supposed to tell the computer if the damper door is open or closed. If it does not go to zero ohms, the CPU doesn't know what to do. Check the thermistor too...... just in case...

Sharp r-1874 - 59 sec


We have the service manual, and have uploaded it to our site here. It is only a supplemental type, so it does not show disassembly, but it has helpful info and part numbers

We have a handy disassembly video at http://www.microwavedisplay.com

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.

The best place to order Sharp parts is Tritronics.

Shuts off after 59 seconds


That would be a problem in the damper aseembly, either a bad switch or motor, or the damper door is jammed or blocked.

Consult the attached diagram for general reference.

The damper switch is the same as the primary interlock (door) switch.

If you or a friend decide to look into it, we have critical safety information, switches diagnosis and replacement, and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Shuts down after 59 sec


Chances are you have a bad damper switch or wiring. A sample photo is here: http://207.234.249.73/mwd/damper.jpg It might also be a problem with the humidity sensor or a problem with the control panel, such as corrupted code or bad connections.
