In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

The microwave unit is faulty as you can read from the display or the controller isn't working correctly, you should take your MW oven to an authorized service center. It can be repaired by yourself but it's highly dangerous because it has high voltage inside and microwave energy.

SOURCE: Sharp Covection Oven/Microwave stops after 1min on any setting

This 59-second stop failure is due to 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 thinks that the door is not in the right position, it will shut down the cook cycle.

See the attached sample photo.

If you or someone you know wants to look into this, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

We even have a video on our site that shows you how to safely & easily remove the control panel assembly to send it for service.

SOURCE: Sharp R-1870 stops at 59 seconds

Wow. I just read something ridiculous!

Well, never mind that, here's your solution:

This is a common 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 R-410LK fan and light do not turn off.


follow this steps and fix it. God bless you

  1. Main control boardIf your microwave runs for a few seconds and stops, the first thing to check is the main control board to ensure that a shortage has not occurred. If the part is defective then it will need to be replaced to prevent continual shut offs. If this is not the issue, the next step would be to check for a faulty touchpad.
  2. Touchpad/Control panelIf the control board is not the issue and your microwave continues to shut off after running for only a few seconds, the next thing to check is your touchpad, which is also known as a control panel. Although uncommon for this issue, symptoms are usually that the display and some buttons are working properly; however, when selected some buttons are not functioning. If this is the case the touchpad will need to be replaced.

Is in demo mode and I can't get out of it


I am familiar with TV sets being stuck in demo mode, but I've never heard of a microwave doing this. The fix for this on a TV is usually pushing a combination of buttons at the same time.

Call Sears or Best Buy and talk to an appliance salesman, or call a repair service. They surely wouldn't charge you anything for giving out this info.

Sharp R8310


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

Here is a link you or someone you know can use to test it, but please read the safety info:

Sharp 1870 just quit cooking and no turntable


The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil
