Carrier FV4CNB005 Defrost Sensor Board

Important hints your outdoor defrost sensor board should need replacing
- The system will cease to function for the simple fact of the amount of frost on the outdoor unit
- Defrost mode will not initiate even though there is quite a bit frost built up
- The main control board may show an error number produced by a failing defrost board
