Question about GE JVM1850 1000 Watts Microwave Oven
I bet it is probably the Magnetron
Posted on Nov 11, 2008
That's probably a shorted high voltage rectifier diode or a bad magnetron.
It should have a nine-year warranty on the magnetron.
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:
http://www.gallawa.com/microtech/diode.html (if it is NOT shorted, it's probably fine)
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.
At our site, we have a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

GE may send you a replacement magnetron. Or you can contact them to find the GE-authorized servicer. GE Customer Service is here.
