Stove top workd, no problem. When, clean, broil or bake selected F5 code. I have checked the wiring loom from the clock control board, checked the oven thermal over heat sensor, okay, oven temp sensor seems to work and replaced the clock control board with a new unit, still get the F5. Presume it's the relay control board, anybody any more ideas before I fork out $245. By the way the broil and bake elements are good.

Nat, thanks for the response. I have checked all the connections more than once, even disconnected the wiring loom and buzzed out the wires with a meter. My back ground is electronics and could have checked more if there was a circuit diagram of the ECU available so I will have APP send me a replacement board and hopefully this will fix it. Thanks for the help
