Check the damper motor - this closes a small metal door usually located behind the magnetron tube. If the unit runs exactly 59 seconds then cuts off, then that's most likely your problem.

I just had an appliance repair man check my Sharp R-1870 microwave for the 59 second shut off problem. He said it was the main circuit board. Has anyone run into this problem. Everything I google says...


I've had a similar problem with a 1983 Sharp Carousel microwave. It turned out to be a faulty door micro switch, the contact didn't stay closed inside it for very long.

Sharp r-9h84 turns on but does not heat


If it has a turntable does it turn or not? If not the safety switch in the door is bad or not engaged--supposed to prevent unit from use with door open---if turntable ok suspect inverter board (power) or the Magnetron itself.

The microwave stops itself everytime at 59 secs if put on for any time over a minute


Change the damper motor and switch. Cost for both approx. $30.00. Must remove cover to gain access to motor & switch.

We have a sharp R-967 combination microwave/conventional oven. It now switches itself off after 59 seconds of operation regardless of which time and/or which function has been selected. Can this be easiliy...


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!

Our microwave/convecton turns itself off after about a minute


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.

Sharp microwave


One of your door switches are bad.

1 Answer

Microwave does not turn off


This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

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