I would suspect a couple of wires are crossed.
GE puts mini-manuals in their units, which have wiring diagrams, schematics, etc. Very handy.
It will be folded up in a small envelope, usually behind the control panel or hidden elsewhere. That should help you.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

SOURCE: Door won't stay closed
I just had this issue happen to me last week.. fortunately I was standing in my kitchen when it happened... I heard a snap and then a piece fall down the inside of either the door or the front key panel.. I'm assuming this controlled the door locking/oven turning on safety mechanism. The inside light wont go off and it won't turn on to cook.. I am trying to figure out if it's worth paying to fix or just replace the whole unit!? Anyone know if this is fixable by oneself rather than spend a bunch of money on a service technician??

the problem your are experiencing with your microwave oven is a failed interlock switch.
Be careful when closing your microwave door. Slamming the door too hard is one of the main reasons that the interlock switch is damaged.
Slamming the microwave door shut can easily blow the microwave fuse, but they can also blow due to problems with the interlock switches.
A microwave oven will not function until the fuse is replaced.
Instruction on how to replace fuse on microwave.
1. Unplug the microwave from the electrical outlet to prevent electrocution. Place the microwave in a well-lit area to be able to locate the fuse.
2. Use a screwdriver to remove the outer cabinet of the microwave, and follow the power cord to the fuse. The fuse is located 2 to 3 inches within the microwave and is attached to the power board.
3. Observe the fuse to determine if it is blown. Blown glass fuses will produce burn marks on nearby surfaces, or the internal fuse wire will be black and melted, while ceramic fuses show no outward appearance of being blown.
4. Determine if a ceramic fuse is blown by testing it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is not blown. Other readings on the ohmmeter show that your fuse is blown.
5. Replace the blown fuse by popping it out of its holder, and snapping a new fuse in its place. Tighten the fuse clips by squeezing them together with your fingers.
6. Replace the outer cabinet of the microwave, and plug the microwave back into the electrical outlet. Test the microwave to see if it's working properly.

If one of the latches has broken off and
is not lifting the other latch clear of the housing. Remove from any
power source, remove the cover of the cabinet. Slacken off the clamp
mechanism and ease the clamp over the guide to allow the door to
open. When a new door lever is in place, the door may be easily
adjusted by slackening off the screws that clamp the door
catch/actuators in place whilst holding the door closed and then
tightening the screws. The rear of the door may be adjusted by
slackening the lower door hinge screws and adjusting as required.
I hope that helps.
If one of the door interlock switches
is not switching properly, that can cause the turntable/light to come
on even though the "Starts" button has not been depressed
due to the wiring of the switches.
Check for faulty door switches and/or contaminated actuators.
I hope that helps.
