A microwave can be dead for many reasons.

The fuse is normally located on the floor of the chassis behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

SOURCE: I NEED A MANUAL FOR

I was looking for a manual for the oven, finally found someone to talk to from Sharp Co.
He did not have a manual but had me try some of the buttons on the front of the oven.
Some, in fact most, of them do not work. It was the convection part of the oven that I wanted to use because I am alone and do not always want to heat the oven for just one small something.
I am afraid it has been stored too long and would cost more to have it fixed.

Thanks for the e-mail.

I stumbled upon the manual at the Sharp website even though this model didn't appear in their database on the first search. I looked up the next closest model, and low and behold there was a link on the page listing R 310. This link says R 312, but it specifies multiple models, including the R-310. http://www.sharpusa.com/files/mic_man_R312A.pdf

Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.

So please post a NEW question, and please include your brand name and the full model number from the tag in or on the unit, as well as the answers to these questions:

Which fan is it?

The internal cooling fan, which comes on automatically whenever the unit is microwaving?

Or the hood vent exhaust fan which you can turn on and off manually?

Or the convection fan, if it is a convection model?

When is it coming on?

Is it coming on whenever you cook on the stove top?

Thanks!
