Microwave convection heat shuts down

My Sharp R930AK microwave will overheat in the convection mode above selected temperature and then shut down. Any suggestions? Is this a home repair possibility?

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.

Convection oven shuts off after a minute when trying to bake. Does this during Compubake also.. Does not preheat

Possibly a bad oven temp sensor. If the uinit doesnt read a temperature it will shut down to prevent a fire or over heating. The temp sensor is a thermister A temperature variable resistor that changes value as the temp changes. so If the main board doesnt get a response within a vertain resistance range it shuts things down. Sometimes since those parts are in the actual cooking area and subject to the heat and steam from cooking they can rust and break, or just get old and break. Or slam the door and break, you get the idea!!

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.

Sylvania microwave convection oven overheats after

you need to remove the cover and after it operates and shuts down(CAREFULLY) feel the magnetron tube sides (BE EXTREMELY CAREFUL<HI_VOLTAGE ON TUBE FROM CAPACITOR) still, then if its not too warm there is a small temp sensor held by 2 screws on the side of the tube and they can go bad and shut off current to the tube,the tube will run warm, but should never run HOT,if its hot its defective

Amana OTR Convection Microwave runs 59 seconds and shuts off

This sounds like either a thermistor or a damper switch/motor problem.
Amana's technical support line is 866-426-2621. This is the commercial side but they should be able to get you in touch with the domestic side.

i dont believe the board to be bad but i do believe the heating element inside is fried or a wire got fried by heat
if you know how to use ohm tester i would check heating element and wireing first
then try to see if the timer gave out
