"F3" on a GE microwave means you have a shorting membrane keypad.
It is part number WB27X10816
and Sears Parts Direct online
indicates that the keypad is still available, but I have my doubts. You will just have to place an order with them, and they will notify you in a few days if it's not really available. Annoying, but they're the only game in town on this part.
If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures
showing you what's typically involved.
If you would like to have me replace it for you, I would do that for $54.95, which includes insured return shipping.
I would have you either order it and have them drop-ship it to me, or order it yourself and include it with your control panel assembly when you send it to me for repair.
If you decide to send yours in for repair, here is the info you need:
For disassembly info, you can watch the video at my site
, or see these text files: http://www.microwavecontrol.com/safety.htm
Be very careful when disconnecting the cables & wires. I would photograph or mark the wires during disassembly. Also, some connectors have a locking tab: WHAT TO SEND
I really need the entire control panel assembly - the plastic frame, keypad and control circuit boards - as shown in the attached example photo.
(So once you've detached this assembly from the chassis of the microwave, no further disassembly is required or desired)
Yours should have a "mini-manual" (technical sheet) hidden either behind the grille or control panel. I'd appreciate if you send that, too. I'll copy & return it. And please include my repair formand include yourmodel number
andFCC ID number
from the tag, or e-mail or print a clear photo of the tag.
(The repair form has my address, shipping recommendations, payment information, and basic terms of service.) TURNAROUND
If needed, I can rush it for you if you simply write "RUSH
" in just the top margin
of my repair form
WARRANTY Unless otherwise specified, I give you a one-year repair
