Question about Sharp Microwave Ovens
If you use a sensor function, the sensor may be obstructed, please clean the sides and top of your microwave with a dishcloth, warm water, and soap to dislodge any rough or stained spots.
If setting a timer, when setting to bake please pay close attention to the unit of measure so that you set it right, minutes vs. hours as you may leave the oven to do its business and return without noticing it did exactly what you told it to do but you had thought you entered a longer time.

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://18.104.22.168/mwd/R930AKAW.pdf) Post back if you wish.

Check the internal fuse. Unplug it, unscrew and take off the cover, the fuse should be easily found in the back by the power cord. I tlooks like a regular fuse but is white instead of clear glass because microwave fuses are special. You'll have to measure it with a meter as a result and be sure to replace it with the same kind. (try finding them at radio shack) Hopefully there isn't something more serious also.

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.
