I recently purchased a new control board from here since the old one died. It worked fine for about a month, but now I am getting the code E1 F2. The code doesn’t appear right away when you power the oven. Rather, it’s only after you turn the oven on to preheat. After about a minute of preheating, I get this code, the oven shuts off and I can’t do anything with it until I power cycle the oven again.
From searching around on the internet, it sounds like the control board is not talking with the control panel, but all of the control panel keys are beeping when I press them. Again, this code only appears after the oven has been preheating for a minute or so.
I don’t want to spend the money on a new control panel if the control board I received is defective and still under warranty. How do I go about determining the cause of this problem?
