Question about GE Spacemaker JVM1640SJ Microwave Oven
I would suspect a shorted high voltage capacitor or high voltage transformer, but normally the internal fuse blows before the breaker does, unless the breaker is rated less than the interval 15A or 20A fuse.
You might also check the door switches & door switch mounts.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
At our Web site, we have a video available 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 for test help, but read their safety warnings first:
(if it's not shorted or burned, it's probably okay)
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
