Double oven chirps and power off reset does nothing. Cold oven chirps, a F0 code was there but does reappear now. Is the control panel the likely cause? The panel will accept commands.

Yes the F0 code is a indication of a faulty control.

The F0 is typically a shorted off key, so your electronic control may be OK. I have helped 860 folks solve the F7 problem and my solution may also work for your situation. I have a free illustrated set of instructions that I will be happy to send to you if you mail me at hutchipop@yahoo.com. All it will cost you is your time.

If you remove the ribbon cable from the control and you get no F0 error msg after power up, this confirms a bad keypad.

The isolation test confirms that the problem is not in the ERC. However, as I have found in my research, the problem may be in the ribbon cable between the ERC and the keypad, aka touchpanel. While the ribbon cable is a part of the touchpanel, there is a solution for one type of ribbon cable fault. I have discovered that a short circuit may occur where the ribbon cable exits the touchpanel. There are usually two segments to the ribbon cable and they are very close together at the slot. The coating over the traces is very thin, less than a mil in thickness. Moisture will cause the growth of a dendrite, a type of corrosion associated with silver traces. The dendrite forms a short circuit which activates the error message as it appears as a shorted or stuck key. In most of the 860 cases I have studied, it was possible to insert a thin piece of insulation between the two segments of ribbon cable and eliminate the short circuit. A piece of paper will work just fine. File card material is good as it allows you to force the material a way down into the slot. Don't worry about the paper burning. It doesn't get hot enough in the top of the oven. GE places printed maintenance instructions in the the top of the oven. In some cases with a metal touch panel, it is also necessary to place thin insulating material between the touch panel slot and the ribbon cable as a short could also occur at that point. Some ovens only have one ribbon cable segment, so in that case with a metal touch panel, you can only insulate the edge of the slot. I can't guarantee this will always work, but it is one way to keep from purchasing unncecessary expensive parts. It is important to turn off the power before poking one's fingers around the controls. Once again, if anyone contacts me hutchipop@yahoo.com, I will be happy to send them a free illustrated set of instructions at no charge.
