International Comfort Products PGAD30D1K1 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin an important defrosting cycle which aids to remove frost build-up that may accumulate. The control board depends on a sensor located near the condenser to agree when to initiate the defrosting cycle.
Red flags your outdoor defrost sensor board should need replacing
- The main circuit board could throw an error code produced by a failing defrost board
- The defrost feature has not run for quite some time especially when there is frost that has built up
- Your HVAC system will cease to operate due to the fact of lack of airflow through the outdoor unit
