It started a few mos. ago when using POPCORN or BEVERAGE setting after a few seconds of heating, the microwave would stop, alarm would sound and -F5- would flash on the display (This error code is not in my manual.)
More recently, I could hear a ticking noise while using the microwave. Then my wife was using it and it started beeping and the oven would not stop cooking no matter what buttons she pushed, she could only stop it by opening the door. I had to unplug it.
Since then, the oven will only cook for a few seconds, then POWER OUTAGE CHECK FOOD would display the clock then needs to be reset.
I was ready to buy a new "Smart Board" our a new microwave. (Probebly not a G.E.!) I have since found that when that when I pull the display assembly away from the frame of the oven that it works PERFECTLY!! But my wife is not cool with keeping it that way!!
I tried cleaning all the connectors on the Smartboard with GB Ox-gard and a soft brush, that's helped a lot. but are there any other suggestions?
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://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
If you or a friend 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 very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.
