Did you check the turn table on off switch on the main control board......Or the board could be the problem.

There is an electrical short. I recommend you do not try to Start it again, it can cause a fire. If it is out of Warranty, buy a new microwave If it is still in Warranty immediately have it repaired by a qualified company serviceperson

how old is it??,, sometimes electronics go out due to age or lightening storms, but you shud be able to find the same model or newer model here>>>www.discountbargainprices.com

That part doesnt appear to be available anymore

Remove outer cover and check if you did not have a spillover from something you last cooked as the center where the turntable fits on has a opening under it and liquid could have leaked through

It's probably an issue with the bottom door switch, or its mount. It's a pretty easy DIY fix. Feel free to e-mail me via my site, and include your full model number (or even better, a picture of the model tag) and include your detailed symptoms to let me know what's happening or not happening, and when it happens. - Ed Miller http://www.microwavecontrol.com

The fuses located on the door switch mount between the door switches.

You will need to remove the outer wrapper, then you can access the fuse.

The bottom door switch is defective due to opening the door while it's cooking instead of pressing the "stop" pad first, or less likely, the bottom door switch's mount is loose, misaligned, or broken.

My daughter put the plate back in wet and the next thing I know it sparked and stopped working. Is it fried?

hi, sounds like the control board. a bad solder. they cost 350.00 so your best bet is to try and disassemble and look for the bad solder joint on the control board, you could possibly take it to your local tv repair shop. here a link to the part. theres two boards one is power supply noise filter and logic. inspect both, make sure you stay clear of the HV red power lines running to capacitor magnetron, use a screwdriver and discharge the capacitor to frame before you start jm Sharp R980A R980A CONTROL CPWBFA753WRK0 Microwave Not Heating Microwave Not Heating
