International Comfort Products PGF060K100F Defrost Sensor Board
The defrost sensor board will determine when to initiate the defrost cycle if necessary, to defrost your outdoor unit. The board looks to a temperature sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Important signs the defrost sensor board is in dire straights
- Most systems will end up not running because of lack of airflow through the outdoor unit
- Defrost session never starts even though there is a large amount of frost that makes the unit run like crap
- The main board could signify an error signal when the defrost control board refuses to initialize properly
