F1 error code on after controller replacement
Model Number: Fcs388cese Brand:
More than 10 years
My controller went black and I purchased and installed a new controller. When I turned the breaker on, the clock worked and the temp said 066 degrees. After a few seconds the controller showed -F1- error code which I could clear with CANCEL button but soon came back. Is controller bad or is something else causing it to go bad?
