SOURCE: Microwave convection heat shuts down

That could be several things, but to me the most likely is that your thermistor is caked with grease - somewhat shorted as opposed to open. By contrast, when the thermistor is open, the classic symptom is that the coolling fan runs more than it should. The other most likely possibilities include the damper motor or switch or control panel. You should be able to get any needed parts at Tritronics at http://www.wehaveparts.com You can find critical safety & disassembly info in the serice manual or at our Web site. We have the actual service manual for that model on our site at http://www.microwavedisplay.com/R930AKAW.pdf (if that URL fails try http://207.234.249.73/mwd/R930AKAW.pdf) Post back if you wish.

SOURCE: heat's water great , won't pop corn

It may be a food placement issue or possibly a bad humidity sensor.

I always recommend that folks put food off-center on the turntable (not in the center) to assure more even heating.

It's a stirring action, so imagine how inefficient it would be to stir just by twirling a spoon in the center of your coffee!

Also, when you put your food off-center, you're not putting it in the same spot every time. That will help prevent repeated heating of the the same spot on the glass, which can lead to weakness and cracking. Microwave popcorn gets hot enough to do that.

We have the entire service manual at our site if your or a friend want to look that over: http://www.microwavedisplay.com/r820bc_bk_bw_sm.pdf

If you need a new sensor, you can order Sharp parts from Tritronics at http://www.wehaveparts.com

Please write back with more details if you need further help.

You probably have a bad thermistor.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

(At that site, that part is misspelled as "thermister" for your model).

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

Accessing some components for testing will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

SOURCE: Sharp 930 AK Convection/Microwave Oven

When you close the oven door the latches operate a couple of interlock switches that control power. It may be that one of the door switches is bad or out of adjustment. It's also possible that one of the door latches is broken so it's not hitting the switch. There should be two door latches. Are they both there? This oven could be fixed by adjusting or replacing the interlock parts as needed. Because of concerns about microwave leakage from an improper door seal, you should have this oven serviced by a professional.

My Sharp microwave convection oven (R-967M / R96STM) cuts out during convection pre-heating and cooking, It appears it stops heating after 1 min. If the START button is pressed again the oven starts...


Also the fact it is a convection oven could mean the oven temperature sensor is not picking up the oven temp. it is not telling the machine it is there by the board seeing its resistance, the unit will shut off as a safety feature. The oven sees temperature by reading the value of a temperature dependent resistor. As the temperature changes so does the value of the component ( oven temp sensor) that way the unit determines the temperature inside the unit. Sometimes those sensors will break since they are in the area with the heat and moisture, they get old and break.
