Carrier 48XPN048090300 Defrost Sensor Board
The defrost control board determines when or if to start the defrosting phase which helps to remove frost build-up that may accumulate. The board is relayed information from a temperature sensor located in the outdoor unit to determine when the defrost cycle should begin.
Key symptoms to watch for in a failing defrost sensor board
- The HVAC system control board may show a particular error code produced by too much frost
- The whole system may stop working for the fact of lack of airflow through the outdoor unit
- Defrost mode has not run for quite some time even when there is a large quantity of frost that makes the unit run like crap
