I need a manual for Sharp Microwave/ Convection R7A85

If you go to the Sharp web site and download the manual, or part you want, there are a few recipes in there, and it looks like they have an offer for a convection cookbook inside the manual.

Best way short of Sharp is Google the model number of the unit with "manual" to try to locate free one online.

You may need to go to a appliance dealer repair man.

The owner's manual for the model microwave oven you have listed can be found at managemylife.com. Just type in your model number under their "Manuals" link and your manual is available .pdf format to be downloaded or printed for FREE. Here is a direct link:

If you need additional assistance, please post back and let me know. I hope this helps you.

you need to remove the cover and after it operates and shuts down(CAREFULLY) feel the magnetron tube sides (BE EXTREMELY CAREFUL<HI_VOLTAGE ON TUBE FROM CAPACITOR) still, then if its not too warm there is a small temp sensor held by 2 screws on the side of the tube and they can go bad and shut off current to the tube,the tube will run warm, but should never run HOT,if its hot its defective

Here's a roundabout way to help you:

You can find a different High-Pointe RV microwave owner's manual here.

That manual should have contact info to help you get in touch with High-Pointe to get a new one, or it may be close enough to your model to work for you.

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

If that doesn't do it, then your keypad may be bad. If so, the unit would have to be scrapped since the keypad is no longer available.
