Question about Jenn-Air Microwave Ovens
Put a cup of coffee in microwave, yes it was a microwave safe cup :) I heard a zapping sound and when I pulled out my cup it was still ice cold
Possible bad inverter board (power) and or the Magnetron which does the main heating.

I see. Okay, well then I would expect there's a problem with a high voltage part, such as the diode, magnetron or transformer.
Your model number should be entered as JVM192002 and you can find exploded views here.
You can usually find GE parts for much less here.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
Here are some links you or someone you know can use for test help, but read their safety warnings first:

It has a bad magnetron. This is the tube that provides the microwaves to heat the food. Not too easy to replace yourself but it can be done. Cost of magnetron is probably less than $50 or $60.

You have burned out the magnatron (heating element) which is common on GE microwaves. most service companies will charge about 200-250 to replace it

Replacing the Magnetron will fix this heating issue you are having with this microwave. The Magnetron is the device that is responsible for the heating action.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
