Question about Microwave Ovens

Kenmore microwave shuts off after several seconds

Problem is two fold. Our Kenmore microwave model # 721.80592 fan started running for extended periods, when not in use. Problem seemed to arise when water was boiled on stove below. Initially this seemed to be solved by pulling plug. Problem has now morphed into microwave shutting off after several seconds. Thermostat was replaced with no effect. Your help is greatly appreciated.

Hopefully the hood / vent fan was always on when boiling on the stove top.

Otherwise moisture can get into and damage the keypad or control circuit board.

That may be the problem.

If this is a convection model, it may have a bad thermistor (not to be confused with a thermostat).

The full model has three more digits, in case you need more help and want to post that.

If you or a friend decide to look into it, 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

You can usually find an exploded view by entering your full model number here: http://www3.sears.com (the 3 is correct)

I have a microwave model # R-308NW. When I press


if when it shuts off clock resets to first plugged in state, sounds as if control panel is being reset by something (failure of part, or power surge) if clock is still ok and maintains correct time , I'll bet if you notice the cooliing fan is not running correctly (by sound it makes) in those two seconds, this will over heat magnetron and shut off on thermal hi temp (safety) if so fan will need to be serviced by a professional

Have Kenmore microvave and the vent starts on its own


Actually, that's a feature! If you cook much on the range (stove) beneath the microwave, the heat will cause the microwave bottom to heat up quite a bit (just touch it!), and the microwave will turn on it's exhaust fan in an attempt to save itself from burning up. It will shut off in about 15 minutes after you turn off the source of heat.
But if the fan comes on by itself even when the microwave is cool (or at least not hot), then you probably have a defective fan thermostat. This thermostat is located behind the control console on the inside bottom of the microwave.

Ge pvm2070smss shuts down


It may be a noisy magnetron if the failure occurs in a second or two of hitting "Start" to begin cooking.

See this FixYa solution. even though your model number is different.

Otherwise, if the internal cooling fan is not running when you are cooking, it will shut down after 30-60 seconds or so and stay off until it cools back down.

Kenmore 721 microwave fan turns on by itself


I have the exact same problem with my Kenmore Microwave model 721 that we bought in October of 2005. The Fan will just randomly turn itself on even when we are not cooking. It has been doing this for the last few months and is starting to become more frequent. There is no way to turn it off except to unplug it for several hours.
Was there a recall for this defect ?

Microwave hood # 721.80833500


One of 2 things are happening..One of the thermo protectors has a bad connection (Kenmore is good for these) or the Magnetron has a leak inside the control cavity causing a temporary short in the control.

Microwave cycles off


Does this happen just at the full power microwave cook setting?

Have you tried defrosting and doe sit do it on this setting? Does it run any longer in defrost mode?

Shuts down after running about 8-9 seconds.


We'd need the full model number to be sure, but it sounds like an inverter failure. Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models. I would call Sears for service. See http://www.sears.com
