We keep getting F3 and F4 for codes. What does this mean?
F3 indicates that the door (or lid) switch has a problem. Possibly corrosion. Replacing the door switch will fix the problem. However, there's always a small possibility that the control board is faulty and is sending a false signal.
F4 indicates the "recirculation pressure switch" has failed.
