    Yes, it does go dead and then comes back on in about a half hour. Now that you mention it I don't think the internal cooling fan is running. It does sound different but I couldn't figure out why. Is that expensive to fix?

    Is the internal cooling fan running while it is cooking?

    (I don't mean the hood exhaust vent fan that you can turn on and off at will )

    Is it going "dead" with no display, then coming back on (with clock not set) in a few minutes?

I have a Samsung model 1032BB in my R.V. Starts up all by itself and then I can't turn it off/on; have to unplug it. Should I have it repaired or should I replace it?

Sounds like the fan is out, and it's overheating the magnetron, then the thermostat trips to protect it.

You can order Samsung parts (and check prices) by entering your model number here.

If your model is SMH7178STD the fan motor (without blade - you use the old one) is $27.69 plus shipping.

You can find your nearest Samsung-authorized service center here.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

At our site, we now have a video available showing how to remove a typical control panel assembly in under 5 minutes. Once that is out, you can see the innards pretty well.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Why can i not cook for 20 minutes with oyster microwave it cooks about 7 minutes an shuts off then about 5 minutes later it starts up again.


The unit could be overheating and shutting down, cooling off, and restarting. Check ventilation holes on back for dust accumulation and blockage. Check that cooling fan is turning properly.

RE: Samsung microwave SMH7187STG mfg'd 5/08. I heated cup of tea 2 min.Then I closed micro's door & micro emitted a continuous electrical buzzing sound.I opened door & buzzing stopped.


The cook relay on your control board is shorted, and the unit is cooking whenever you close the door.

When the magnetron overheats, its thermostat opens, shutting power down until the unit cools to a safe level, then power is restored.

I regularly repair these with my $54.95 service, which includes insured return shipping.

Details are here, or for full information and instructions, please e-mail me here at pupista@gmail.com and remind me of your full model number and symptoms.

The thermal overload sensor on the Hi voltage transformer is shutting it down to prevent smoke and potential fire. The transformer is getting hot. It needs to be replaced.

It has nothing to do with the microwave. Unfortunately, it sounds like the LED bulbs are defective and should be replaced.

Jenn air microwave model jmv820aas shut down completely, what do i do?


I'm guessing you might mean JMV8208AAS?

If so, then the service manual is at our site here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel which is very helpful when troubleshooting, testing, and locating components.

mini_manual_behind_grille_small.jpgdee77f7.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can order Jenn Air parts here.

Your problem will be either the line fuse, or one of the thermal cutouts / TCOs in the unit.

In case it needs circuit board repair, see this link.

It sounds like the thermal fuse may be defective, or the fan is not running, or the magnetron is getting to hot. If there are any heat issues the thermal fuse will cut power and reset in 5 minutes.

During cooking, the microwave will work for about 3 minutes then completely shut down.There appears to be a complete power failure.After the units sits for about 5 minutes,it resets itself and you can cook...


sounds like the cooling fan has came adrift or stopped working , this will cause the magnatron ( the microwave generator ) to overheat tripping the over temperature stat ,so fix the cooling , but be sooooooooooooo carefull in there , microwaves + really high voltages , not really a job for a non electrician/microwave tech

Microwave not heating, but does count down minutes.


Press clear/reset button and hold 5 seconds. If this doesn't work unplug unit or shut off breaker for 10 seconds.
