Question about GE Spacemaker JVM1640SJ Microwave Oven
Assuming that your internal cooling fan is working, I would suspect that your magnetron is failing.
You can usually find helpful exploded view diagrams and order parts by entering your full model number 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, and locating components.
I would check the cooling fan, then suspect the magnetron.
