International Comfort Products PHF036K000A Defrost Sensor Board
The defrost sensor control board will begin the defrost sequence which helps to keep the outdoor unit free from frost build-up. It depends on a defrost sensor which is near the condenser somewhere, in order to agree when to begin.
Key clues of a poorly performing defrost sensor board
- Your HVAC system will cease to operate for the fact of frost blocking the airflow outside
- Defrosting never kicks in especially when there is frost in the way
- The control board may issue a specific error code produced when the defrost control board fails to receive a signal
