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://184.108.40.206/mwd/R930AKAW.pdf) Post back if you wish.

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.

if you google the model number and the brand you should be listed with a series of sites that supply manuals, service manuals, etc.

is a problem in one of the damper-related components, either the switch
or motor or the damper door may be binding.
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 drawing 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.
If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
