Hello, Derek - Is the Sharp Convection Grill Microwave either model R-820JS or R-820BC? If so . . . The cooking directions begin on Page 24 of the Operation Manual. If you do not have the manual, you can find it as a PDF document (Adobe Reader software needed - free) to download for free here: http://kitchen.manualsonline.com/manuals/mfg/sharp/r820js_r820bc_1.html The cooking instructions start on Image 27 of the PDF document and run through Image 30 (Page 26.) I would choose the convection cooking temperature for either Frozen Convenience Foods or Pies, Frozen Prepared. Best wishes.

No use on fixing the oven. They cost $150-300 so why bother?

Hi,
You will have to replace the power control board...

Assuming your hinges are tight, your bottom door switch is probably defective, or its mount is loose, misaligned, or broken. This is usually caused by opening the door while it's cooking (instead of hitting "stop" first) or slamming the door. I have the service manual at my site here. See my help file on door switches here. More questions? Contact me directly here.* * always include the full model number and FCC ID number from the label on / in your microwave (or a clear photo of the tag)

I would guess that the boiling water may not have been the cause ... If you are lucky ... try this first: Unplug or turn the circuit breaker off (if it is a built in unit). Wait an hour and then repower. Odds are that will not clear things up ... but it is easy to try. Probably one of the electronic internals broke. A number of different internal component problems could cause this heating failure in the microwave. It could be the magnetron, the high voltage transformer, the PC board, the diode, and the capacitor. This type of problem will need to be diagnosed and repaired by a service technician. Microwaves are inherently dangerous to service. This type of repair is not something that you want to try to do yourself. Internal capacitors in the microwave can retain a lethal electrical charge even when the microwave is completely unplugged. A microwave radiation leakage test should be performed on the unit using proper testing equipment following any internal component repair.

Verify 15 or 20 amp fuse is good use a multimeter check continuity if no meter replace fuse to rule out it's got to be a power problem.
