SOURCE: Our sharp 957 will now

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.

This is also likely why your convection mode stopped working.

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.

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

Testimonial: "traced to motor for damper. Would not have had a clue without this information provided by fixya"

SOURCE: 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.

SOURCE: We have a sharp R-967

Hi,

I see its some time ago now that you posted this and perhaps you've fixed your micro already or replaced with a new one. I have the same Sharp r-967 microwave which had the same 59 second problem. I researched a bit online found the sevice manuals and tracked the problem down to be the damper motor. I managed to buy one online and replace it quite easily. There are some diagrams online when searching for this problem but for different sharp models where the damper is near the door fixings. Its not the case on r967, its behind the circuit board and easy to remove with a stubby screwdriver. You can find spares from this place. 5 minute job. The 59 second thing is likely to be the either the door switches or the damper motor. Switches are between £5-10. All mine were fine so didnt have to replace any. A quick voltmeter test can check them.

I paid £26 in delivery. Hope it helps if not too late!

cheers

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.

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?

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.
