Got a GE wall oven with the F0 code. Throws the code any time, whether or not it's being used. I tested the key panel according to the tech sheet
and it checked good. All keys work and no shorts between the pins. I like how the tech sheet says if key panel tests good the problem is "probably" with the control. Both the control board and the panel are expensive and factory order. I'm leaning toward the control board but would like to be sure before I order it.
