International Comfort Products NDN6100GFA1 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost sequence which actually helps to remove frost build-up that may accumulate. The control board relies on a sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
What are the signs that the AC defrost sensor board is in need of a replacement?
- The control board may show a type of error code produced by a failing defrost board
- AC and heating system could stop functioning due in part to frost blocking the airflow outside
- Defrost session refuses to initiate even though there is quite a bit frost built up
