Question about GE Spacemaker JVM1640SJ Microwave Oven
This means your magnetron is overheating, and the magnetron thermostat is doing its job - killing the power to prevent more damage to your magnetron.
This is usually caused by the magnetron itself being bad and overheating, or a failure of the internal cooling fan, allowing it to overheat.
If you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk
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.

If the magnetron is bad and it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.
