Question about Microwave Ovens
I have a GE Spacemaker model JVM1653SH01. When the unit it turned on to cook, it works for only a few seconds then turns off. I am required to reprogram the time and date in order to get it working only to have it fail again.
Sadly, we hear of this over and over.
This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.
If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.
It may also need a new high-voltage diode and stirrer, and the cavity may be affected.
Details are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit. The parts kit is similar to this one.
(Your model may use a different kit - this is shown for illustration purposes only).
If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.
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.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
If 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.
They may send you a replacement magnetron. GE Customer Service is here.

Tips for a great answer:
If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently
the microwave runs for a few seconds and stops the touchpad and
control panel might be defective. There are several other components
that can cause this problem, be sure to check any other components
before replacing this board.
the microwave runs for a few seconds and stops the touchpad might be
at fault. This is not common. Generally speaking, if the microwave
display is working and some of the buttons respond correctly but
some don't, the problem is with the touchpad.
the microwave runs for a few seconds and stops the thermostat might
be defective. Watch our video on testing thermostat
