Fault codes are programmed in air conditioner controls to help service technicians quickly diagnose issues with the unit. In the event that the electronic control displays a fault code, a trained service technician should be called to diagnose and correct the issue. We do not have a list of all the possible fault codes and their meanings since they all indicate a service issue.
