Fisrt, check to be sure your missing cat it not inside the unit. IF the interior is dirty (splatters, grease, etc.) , it may inhibit the unit from working properly.

have, I would most strongly suspect a shorted high voltage rectifier
diode or a bad magnetron, or a loose and possibly corroded connection
on the magnetron's terminal.
The diode is a fairly cheap fix, and the mag will cost more.
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.
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.
Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted or burned, it's probably okay)
(it may pass the checks and still be bad)
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.
If it's under magnetron warranty, GE will send you the magnetron to do it yourself. Call them at 888-239-6832.
Be persistent. You may have to speak with a supervisor.
