The fan on my Sharp R930AK won't stop after broiling.

check the door lever

Your problem may be the bake relay on the clock or wiring.try changing that

Control board has failed.

Good Afternoon Gwen - Try reprogramming the range by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes and turn the unit back on. If issue persists, then the unit could possibly be experiencing an issue with a wiring failure, EOC (electronic oven control), sensor probe and/or faulty bake or broil element. I would strongly recommend consulting a professional to narrow down the precise issue before investing in parts that may or may not be the root cause.

Great news

That would be a defective secondary (lower) door switch or possibly the door switch mount is loose or misaligned.

Control board has stuck relay or triac ( electronic equivalent of a relay) . Replace control board.

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.
