Question about GE Spacemaker JVM1640SJ Microwave Oven
Okay, thanks for the info. For reference, if it's older than 9 years, the magnetron will not be under warranty.
I'd say you have a shorted high voltage rectifier diode or a bad magnetron.
There should 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.
At our site, we have a video showing how to remove a typical over the range control panel assembly in under 5 minutes.
Here are some links you or someone you know can use (in order given) for more test help, but read the safety warnings first:

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
