Hard to say, you could have a bad keypad, or you could have a shorted oven sensor. If your microwave is still heating on some settings and not others, I would look there, if your microwave is completely losing power when your starting it when you set it for 1 minute and hit start, then you probably have a bad TCO on your magnetron getting hot and losing connection. It could be that your Magnetron is getting too hot or just a bad connection on the TCO. If the magnet is cracked, I would replace the magnetron. I would recommend calling a professional if this is installed over your range, if you have ge service available I would go with them usually it takes two people to safely pull down a microwave. I would definately test it before reinstalling it again. 1800 GE CARES for gea service ask for the best deal if the magnetron needs replacement they are expensive.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.
You may have a problem with the keypad or the control unit (circuit board / smart board).

You have a failed
membrane 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 find links to helpful exploded view diagrams and part ordering help here.
I recommend that you bookmark that link to your favorites.
There
should be a "mini-manual" (tech sheet) hidden inside the unit
behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating
components.
If you would like to
have us
do this repair for you, we do that for $39.95 plus part costs nationwide.
But please note that for
some GE models, the membrane keypad is not
available as a separate part, so you would have to order the control
panel frame assembly which comes with a new keypad.
In this case, you simply
move your circuit board into the new frame. That is a simple do-it-yourself
job.
Either way, we can let
you know what your options and costs would be and send you other
helpful info.
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.
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.
