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.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site. The best place to order Sharp parts is Tritronics.

Microwave stops after 59 seconds


Check that a "favourite" setting has not been selected. The unit may think that is the time that you want to cook. Im not sure about your model but see if there is any clear or cancel buttons to clear any pre programmed selections. If not, unplug the machine for 15 minutes to reset the controller and try it again.

My Sharp R-975 Microwave after settin the timer and starting only runs for 59 seconds and stops, I can press start again and it goes for another 59 seconds


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.

I'm not sure this is a US model or if parts are still available, so look up Sharp in your country.

Our sharp 957 will now only microwave for 59 seconds then stops and rattles for thirty seconds. The convection option stopped working ages ago. Any ideas please?
