TO RYNEAU:
The cooling fan is critical! If the magnetron overheats too much or too often, it can fail, and that adds to the repair cost.
If you or a friend decide to work on it, 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 very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.

TO MARTYB704 & GUEST:
I think you have a different problem than Ryaneau.
This is usually 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.
GE had a campaign (but not a recall, mind you!) covering several models.
Details are in their bulletin at http://207.234.249.73/mwd/ge_mw_mag_kit_bulletin.pdf
Even if your model is not on the list, the same problem can occur, requiring a kit. I just think the difference is that GE has stopped paying
for the repairs.
The parts kit (that GE used to pay for) is part # WB27X10489 and is shown here: http://207.234.249.73/mwd/wb27x10489_ge_mag_stir_kit.jpg

Your magnetron is overheating and tripping the thermostat, which interrupts power until it cools.
Since
it's less than one year old, it should be fully covered under warranty.
I'd suggest contacting the manufacturer to get it fixed free.

sounds like the cooling fan has came adrift or stopped working , this will cause the magnatron ( the microwave generator ) to overheat tripping the over temperature stat ,so fix the cooling , but be sooooooooooooo carefull in there , microwaves + really high voltages , not really a job for a non electrician/microwave tech
