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.

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)
