Model P T970S R2SS, over the range microwave oven. Works normally but has recently started emitting a humming sound when door is closed and unit is idle.
Humming when door is shut. Model #JA229216B 2013. Ge microwave.

The rectifier diode could indeed be bad. But first I would want to know what value (in uF) the old one was and what is the value of the new one? If they're too far off, the difference in the capacitive reactance could throw off the "tuning" of the circuit. The uF value of the capacitor is optimized in relation to the other components used in the system. Of course, you'd also want to be sure your new cap is at or slightly above the working voltage rating of the old one, too.

That model number has too many digits after the JVM. Could it be JVM1339BW02 or JVM1339BW002?
If one is bad, it's probably the bottom switch, whose wiring goes back to the power relay, thermostat, or fuse, depending on eact model.
The switch with thin wires going to a ltitle connector on the board is the door sense switch. That's not likely your culprit.
I usually recommend you replace them all while you're at it.
It sounds like it may actually be a loose or misaligned door or door switch mount.
If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

GE models have a very helpful "mini-manual" hidden inside the unit behind the control panel. Handy in troubleshooting.

F-3 means shorted touch panel pad.

You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

Thanks for the photo of the label!
It shows the FCC ID number, which I used to find schematics at the FCC Web site.
The problem is a shorted primary interlock switch.
This is the door switch which has two black wires connected to one terminal and a black and a blue wire connected to the other
terminal.
