International Comfort Products PGC036L100F Defrost Sensor Board
The defrost control board will begin the defrost cycle which may be needed in order to remove frost build-up that may accumulate. The defrost board looks to a specific sensor located somewhere by the condenser to determine when the defrost cycle should begin.
Main clues your International Comfort Products defrost sensor board is failing
- The AC may stop operating because of frost blocking the airflow outside
- The defrost feature never begins despite that there is a large amount frost in the way
- The HVAC system control board could throw an alphanumeric error code referring to the failed defrost sequence
