SOURCE: Microwave shuts off after a few seconds
Nov 22, 2007. I also had the 3 second shut off problem with my G/E 1650 MWO. Read all the above and tried them all. Finally I just took a 8" x 8" piece of Reynolds Wrap Aluminum foil and but it in an zip lock bag and placed it behind the control panel. It's been working for 2 weeks now. Just take out the 2 screws that hold the vent across the front right above the door. Next on the right side is one screw, take it out and then gently lift the control panel (panel with the buttons) about 1/2" and it will fold out and stay there. put the zip lock bag inside. Close it back up. I'd test it before replacing all the screws. You don't need to un-plug anything. Just don't stick your fingers on all the exposed parts...Mine works great now and didn't cost $0.10.
If you just put the fan blade back on, it will almost certainly fall off again.
The best bet is to slightly rough up the contact area of the shaft with sandpaper and use a little super glue to hold the blade assembly on the shaft, and let it set a few minutes before using it.
I always recommend that you use the hood vent exhaust fan when cooking on the stove top to keep heat, steam, and
grease out of the controls.
There
should be a "mini-manual" (tech sheet) 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.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
You can find
helpful exploded view diagrams and order parts by entering your full
model number from the tag on the oven here.
Feel free to contact me directly (and please remind me of your
full model number from the tag on the unit) for more information & help.

The
first thing I would suggest is a hard reset. Unplug the unit for a
minute or so. Then plug it back in, set the clock and try again. If that doesn't work,
leave it unplugged for about 5 minutes.
Otherwise, I would suspect a "noisy" failing magnetron.

One way to test it is to do the following:
1. Unplug the microwave or turn off its breaker.
2. Open the door, then detach the control panel as shown in the video at http://www.microwavedisplay.com and swing it down, but without disconnecting the wires. If you have any trouble getting the grille off once the screws are
removed, slide the hood vent grille to the left about 1/4", then then
pull it forward. On some models there are L-shaped clips that fit
into a slot to hold bottom of the vent.
3. Plug the microwave back in.
4. Make sure neither you nor anyone else reaches in behind the control panel. There will exposed high-voltage connections.
5. Put a few cups worth of water in a microwave-safe container and place it inside the microwave.
6. Shut the door.
7. Run the microwave for about 1 minute or so on full power. (Time Cook > 1 > 0 > 0 > Start, e.g.)
8. If it does not fail, try it several more times.
9. When the water boils, change the water and try again.
NOTE:
If your model does not have a door handle, you will need to unplug the
oven and reattach the control panel to be able to open the door.
If
it still does not fail, I would recommend that you put it all back
together and keep using it until it fails more consistently, then
repeat this test.
While
a microwave should never be left
running unattended under any circumstances (as your owner's manual will tell
you) it's even more important when one is exhibiting a failure or any
odd behavior.
So play it safe and stay with it while it's running!
If
you or someone you know want to replace the magnetron yourself, you will need to remove the oven from the wall.
If
so, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward.
You can download GE
owner's manuals and installation instructions 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.
Sometimes they will
send you the magnetron to do it yourself. Call them at 888-239-6832.
Be persistent. You may have to speak with a supervisor.
If it is not within the magnetron warranty, you can find helpful

The mag's little cooling fan probably broke loose and fell off the fan motor's shaft. The fan keeps the mag cooler. The machine shuts down when the mag gets too hot because the fan blade is just lying in there, Needs to be glued back on the shaft after the shaft is roughed up a little. NO other parts needed. I used contact cement to hold the fan to the shaft. Its located right behind the control panel. It's not difficult to repair.
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
If
the microwave runs for a few seconds and stops there may be a short
circuit in the main control board. Check other components first,
these boards are often misdiagnosed.
If
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.
If
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.
If
the microwave runs for a few seconds and stops the high voltage
transformer might have an intermittent short. This is not common.
Check other components related to the microwave symptom first.
If
the microwave runs for a few seconds and stops the thermostat might
be defective. Watch our video on testing thermostat
