GE Dual Wave III - Caught on Fire

20 January 2013 - 10:41 PM

I don't have a good guess as to what might have caused this.  The microwave has a removable metal rack held by 4 clips, 2 on each interior side wall.  During use this evening, one of the clips caught on fire.  My wife was running it at the time.  She didn't say there were any sparks.  She said she heated some food and the plastic on one clip had started to turn black.  She took the food out and ran it again to have a look through the door, and it caught fire.


Any ideas what could cause that?? 

GE Wall Oven Model jkp14wp2wg - Code F4

23 April 2009 - 06:14 PM

My GE Wall Oven (Model# jkp14wop2wg according to the plate on the door, but jkp14wp2wg [without the "o"] everywhere else) threw an "F4" code a few weeks ago.  My local appliance repair guy said that his trusty book instructs him to replace the temp. sensor and the ERC.  But the ERC is no longer available, so while he could just replace the sensor, there's no guarantee it would fix anything.

I went to test the resistance of the temp. sensor, but I was frustrated to find that it was crimped to the oven wiring rather than having a Molex type connector, so I couldn't remove it without cutting wires.  So I did my best to test it while still wired up, and got a resistance of something like 850 Ohms.  I expected that a failure would indicate infinite resisance.  So I'm not sure what to make of my reading. 

Since the ERC is no longer available, it will have to be rebuilt rather than replaced.  Before shipping off the ERC, I turned the oven's power back on to double-check the code, and like any other computer I guess, rebooting it cleared the problem (for a while.)  No surprise that now the F4 code is back and rebooting isn't doing the trick any more. 

Now, based on the repair guy's word, it should either be the temp. sensor or the ERC.  If it were the temp. sensor, I wouldn't expect that "rebooting" the oven would fix it.  So I'm guessing that it's the ERC.

But before I spend the $135 to send the unit off to be rebuilt, I thought I would see if:

1)  Can anyone second-guess my reasoning when I assume that the partial success with "rebooting" the oven indicates that it must be the ERC?  Or, perhaps, does someone have direct experience with this behavior and have insight to offer?

2)  Is there a way to test the temp. sensor resistance from the wiring terminals at the ERC?

3)  Is there anything else you would do to make sure you weren't wasting money on unnecessary repairs?

Thanks so much.
