GE JVM231WV001 Stopped Working

That is a hard one without looking inside the workings to isolate the loss of power.

It may be a bad door switch or mount.
(Anybody in the home opening the door while it's cooking?)
See our help file on door switches here.

Check the manual:

1= reset the c.breaker from your home see if are tripped and reset.
2= open for thermal fuse open, test continuity with DVOM OR VOM and replace.
3) test the power cord for open or broken or break.
4= check the switch for door maybe is open must be continuity until 0 , or swtich defective see the diagram attached. God bless you

Yes! unplug microwave, remove top, "several screws" look to the right where the keypad control board is, look down to the circuit board should be a fuse near by that is clipped in, pop out and replace with same current rating, assemble before testing.

good day,
hope this link below will solve your problem.

hello kmwnky,
You say that Everything went out at first ( which I assume means that all functions went dead) and then functions started to operate again later... if that is correct and you smelled something burning.. you may have a thermal fuse that failed, filament transformer that failed, magnetron tube that failed or a highvoltage capacitor that failed.. None of these components are something the untrained person should attempt to trouble shoot or replace since there are dangerous energies stored inside the electronics compartment even after power is removed.. Your Micro is > 8 years old and it's probably not worth the cost of repairing at this point. You'd be better served replacing it.. The cost to repair would exceed the cost to replace.. ( I feel like the grim reaper here..sorry..)
Regards,
Rick

I think its the mag tube, mine went out the same way. GE will provide the mag tube for free just call them...have a local ge certified tech out to put it in.
