International Comfort Products H8DNL075B12B1 Defrost Sensor Board
The defrost sensor control board will begin the defrost cycle which may be needed in order to continue normal heating and cooling operations. The board depends on a specific sensor located near the condenser to decide when to begin.
Hints your outdoor defrost sensor board will need to be replaced
- The defrost feature does not run even though there is a large amount of frost on the unit
- The main control board may throw an alphanumeric error code produced by a failing defrost board
- The system may stop working due in part to lack of airflow through the outdoor unit
