Question about GE Spacemaker JVM1640SJ Microwave Oven
Yes! On many GE models (yours included) the internal cooling fan has a built-in tap (like a transformer) that powers the turntable motor, and in some cases, the stirrer motor, too.
If the internal cooling fan does not run, the magnetron can overheat in about two minutes and overheating too much will destroy it.
If the stirrer is not running, arcing will occur which will damage the stirrer and eventually the magnetron.
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.

The oven should not be used - and should stay unplugged - until it is repaired.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
SAFETY IS PARAMOUNT
This is a job for a professional but if
you are safety clued up, here's instruction.
Make sure the !!!!any capacitors are discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), 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.
