I first called a GE service tech in to diagnose the problem. He said very quickly that the oven circuit board had a fault in it. He said it would cost $ 563. to replace. I asked him if he thought I was a fool or an idiot? Of course he didn't get the job. Before the Tech came I looked up this problem on Appliance Parts Pros.Com and found the same problem. The fix was a new oven circuit board at $163. including S&H. I ordered,after the tech left, the part and received it in 2 days. When my wife and I installed it, it wouldn't work. I call Appliance Parts Pros and they sent me a replacement part in 3 days.
It's very important to replace each wire in the same place. As you take one wire off ( we used a needle nosed pliers) replace that wire in the same location on the new board. You will need two people to do this job. When that is complete be sure to screw(4) the board tight. If the board is not tight it will not work. Tools you will need a star bit screwdriver to remove the front panel and a phillips screwdriver to attach the board to the front panel.
