During operation, most of the built-in models have a panel that tilts out while the exhaust fan is on. When cooking is done, the exhaust fan shuts off and the panel retracts to its normal position. With the fan & microwave motor off, the hum is easier to hear.
Look closely at the top panel the next time you hear the hum, and you'll probably see that it's retracting.

Word has it that many of these models have a defect which causes the microwave energy to be reflected back to the magnetron, causing damage to the magnetron, and eventually damaging the high-voltage diode too.
Also, the fuse or the magnetron theral cutout / thermostat can eventually blow, too.
There is a replacement magnetron and stirrer kit available.
I would definitely call the GE Answer Center at 800-626-2005 about this. It's not considered a recall, but a "campaign".
They may pick up part of the cost. It's not cheap.
In my professional opinion, it sounds like you have a shorted relay or other defective component on your control circuit board, which is actually made by Samsung.
We regularly repair these control panel assemblies nationwide for $32.50, so the problem can certainly be fixed economically.
Looking at typical microwave wiring shows it has to be the cooking relay or a device that drives that relay.
Since it stops when you open the door, we can say the door switches are certainly doing their job.
