Trouble shorting Light will on/off by self then show F3

An F3 code means that the touch pad has a short. The touch pad needs to be replaced. If you purchased the microwave new, get your receipt and the unit serial number and contact GE for the repair (1-800-GE-CARES). See http://repair.geappliances.com/ to find a repair center near you. There is a one-year parts and labor warranty on this part. You will need to get the unit to the GE Repair center at your own expense. (I'm assuming that the unit wasn't shorted by a lightning strike or other disaster.)

I hope this helps.

Unplug the unit for 1 minute to clear the ECU.
re-plug, and re-try.

Thanks

F3 means you have a shorted membrane keypad.

Depending on the model number, you may have to peel off and replace the membrane keypad, or you may be able to replace the entire control panel frame, which has a new keypad already.

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.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

This code will occur if a shorted key panel is detected continuously over 60 seconds. Replace key panel (also called touch pad).

I report from owner manual.

F3 means : Short circuit on key panel (your touch pad).
You get F3 error if a shorted key panel is detected for more than 60 seconds.
Solution: . Replace key panel (touch pad).

Try first unpluggign power cord for five minutes.

If you think that the problem may had been caused by water inside the keypad you can try using an hairdryer on the keypad, taking care not to melt the keypad plastic.
If that does not work, then replace the keypad.

You can buy replacements here. or Order GE Microwave Ovens Parts Here

The code f3 is a short in the key pad for more than 60 seconds
go to GE .com and enter your model # and you can get a price to do it your self
Good luck

F3 on a GE / Hotpoint microwave means you have a shorted keypad.

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.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
