Question about Microwave Ovens
Sadly, we hear of this over and over.
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://18.104.22.168/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://22.214.171.124/mwd/wb27x10489_ge_mag_stir_kit.jpg
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: http://tinyurl.com/yzjozk
There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.
