Our Ge microwave shutsdown completely when we attempt to heat anything. The entire microwave locks up and you cannot use it. Any ideas or suggestions for repair, or should we purchase another microwave.
It may be a noisy magnetron if the failure occurs in a second or two of hitting "Start" to begin cooking.
See this FixYa solution. even though your model number is different.
Otherwise, if the internal cooling fan is not running when you are cooking, it will shut down after 30-60 seconds or so and stay off until it cools back down.

SOURCE: GE SpaceMaker Microwave suddenly stops while heating
I had same problem last week. My GE JVM1650 Spacemaker stopped after a few seconds of heating. Owned 16 months, manufactured Jan 2005. It was the magnetron, which was replaced yesterday. The magnetron has a 10-year warranty, but I had to pay $161.00 for labor by a GE technician. The call-out fee was waived at my request. I don't know what that amount would have been, but I can't believe the $161.00 for what was about 1/2 hour labor once diagnosed. Good Luck!

Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

Magnetron may be defective. Replace the magnetron by a new one.

With the details you described, the high voltage diode might be shorted( usually HVR 1X). It is connected from the Capacitor and the chassis, or else the capacitor is the one at fault,but not common .
