I burned a plastic cutting board on an old (at least 15 years GE self cleaning oven stove. The coils have -genuine calrod unit - in the center of each. I can't get all the plastic off the underside of the coil and my husband tried to burn it off and the fumes were horrible. Can you please tell me how to get all the plastic off. Thank you very much.

Self cleaning programs break things 80% of the time. You should never ever use that cycle. 650'F is too brutal to elements, fans, latches and circuit boards that are above the oven. I have never known one with a manual latch.

You need a new stove or a GE Technician service call.

Even parts seem hard to come by if that model number is correct.

My GE stove is 46 years old :>) The only part that doesn't work is the clock

lock door turn dial to clean

The oven is way overdue for replacement.

Ok, unplug the unit for 5 minutes to reset the main circuit board. if the error continues to plague the unit, replace the control board.

It could be a micro switch in the latch mechanism not communicating properly with the display circuit board, or it could be the circuit board itself. The switch might cost 20 or 30 dollars, but the board could be hundreds. Kinda costly if you ask me...

Bad oven control circuit board. Look up on eBay

yes you may have to select a start and stop time on the clock.scrape all you can out before cleaning though

1. Do both coils get red hot? Try with bake @ 400F, then with broil to be sure. I recently had a bad lower bake coil, but the oven got hot slowly since the broil top coil comes on periodically to even up the heat in the oven. Replacing the lower coil was easy, about a 15-min job, but I had to pre-tap the screw holes on the coil terminals since my oven had extremely short wires.

2. If the coils are ok, the problem may be with the thermocouple or control board.

this a common complaint when the element burns out it is scary to see but all you need to do is replace element

Try removeing power too unit for a couple minutes. You can due this by turning off breaker. Sometimes this will reset board. If not, you may need an ERC board.
