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.

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.

Microwave plate turner keeps spinning even with door closed and microwave turned off


My microwave is doing this as well; It's a frigidaire model #FGMV154CLFA.

After using the microwave part (it is also convection), the light stays on in the microwave and the turner keeps turning.

And I've only used the convection part of my microwave a couple times and I'm not sure if I was successful. While trying to cook something in convection mode, I pressed convection, then pressed the temp i wanted, then convection, then keyed in the time I wanted the item to cook. The microwave started and the timer started counting down but the countdown stopped with 8 minutes left? I left it alone to see what would happen and it never finished so I restarted the process again.

PS..I've never gotten an error code

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.

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.

Round soft key OXO Timer I need to change the clock time their model # is 1061978


Operating functions:
To set the clock, press and hold the clock/timer button for three seconds. A clock icon will appear on the left side of the screen. Input the time using the numerical buttons and then click the clock/timer button to save the time.
To set the timer, press and release the clock/timer button so that the display shows all zeroes. Enter the desired time using the keypad. Press start/stop to start the countdown. The countdown may be paused by pressing the stop/start button and resumed by pressing the same button again.
When countdown is complete, timer will beep continuously for thirty seconds and display will flash. Timer will then beep every ten seconds for ten minutes until the stop/start button is pressed.
This timer will also time up to time activities. To start count up, press clear/memory so timer reads all zeroes. Press stop/start and a plus sign will appear on the right side of the screen as the timer begins counting up.

Amana OTR Convection Microwave runs 59 seconds and shuts off


This sounds like either a thermistor or a damper switch/motor problem.
Amana's technical support line is 866-426-2621. This is the commercial side but they should be able to get you in touch with the domestic side.
