I am getting a double error code on the display, E1 and F2- After turning the breaker back on, the error codes will pop up after about a minute or so and cannot be cleared as the panel seems dead. The repair info seems to indicate that the membrane switch may be bad (which of course is an expensive part). I checked to see that the tail or input cord from the switch is fully into the PC board and it seems to be.
Is there any other potential cause that I can look for before replacing the panel?
