Carrier 48HJD008 Defrost Sensor Board
The defrost sensor control board commences the defrost sequence which actually helps to remove frost build-up that may accumulate. The board is relayed information from a sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Major symptoms of a defective Carrier defrost sensor board
- Your HVAC system will stop running due to frost blocking the airflow outside
- Your main control board might give out a type of error code produced when the defrost board is bad
- Defrosting never starts despite the fact that there is a lot of frost that needs to be removed
