Question about GE JVM1650 1000 Watts Microwave Oven
When microwaving anything for more than 4 or 5 minutes at a time or about 8-9 minutes total (high heats, defrost can go about 10-15), the oven will completely shut off. Not just stop heating but power and everything as if the circuit blew and there is no way to reset it until it turns itself back on 20-30 minutes later. Now is it possible this is simply because the charcoal filter is older and so it is not recycling the air properly, or is it something more than that (needs a new fuse, etc)? Any help would be great!
First of all, yes, the charcoal filter should generally be replaced every 6-12 months, or as otherwise specified in your owner's manual.
If the filter clogs, that will block air flow, which is critical to keeping the magnetron cool and safe.
If the magnetron overheats, its thermostat trips, shutting off power to the oven until it cools back to a safe level.
You can remove the filter, then try the oven a couple of times.
If it works right, then you know it's the filter.
If it still fails, then your fan may be out or the magnetron may just be dying.
Also check and be sure your air filters are clean. They can be washed, while the charcoal types cannot.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, 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.
