International Comfort Products PGC048H080F Defrost Sensor Board
The defrost control board will determine when to initiate the defrosting phase which may be needed in order to remove frost build-up that may accumulate. The board depends on a temperature sensor which is near the condenser somewhere, in order to ascertain when to initiate the defrosting cycle.
Clues the defrost sensor board is in dire need of a replacement
- The system may not run for the simple fact of the safety features installed
- The primary control board could throw an error number when the defrost board fails
- Defrost mode never kicks in even when there is a large quantity of frost on the external unit
