Goodman GDH80904BX Defrost Sensor Board
The defrost control board commences the defrost cycle if necessary, to defrost your outdoor unit. The board is relayed information from a temperature sensor located somewhere by the condenser to decide when to initiate the defrosting cycle.
Subtle hints the AC defrost sensor board needs to be replaced
- The defrost sequence never kicks in especially when there is frost built up
- The main board might issue an error number when the defrost control board refuses to initialize properly
- The whole system may stop working due to the fact of lack of airflow through the outdoor unit
