International Comfort Products PGC036K100A Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin an important defrosting cycle if necessary, to remove frost build-up that may accumulate. The defrost board is influenced by a sensor located in the outdoor unit to determine when the defrost cycle should begin.
Red flags the defrost sensor board is failing
- The primary control board might give out a specific error code produced by a bad defrost control board
- Unit defrost session will not kick in even though there is excessive frost that has built up
- Your HVAC system will stop working due in part to the safety features installed
