Carrier 48XL-A48 Defrost Sensor Board
The defrost sensor board commences the defrost sequence if necessary, to get rid of the frost that collects on the outdoor unit. The board looks to a defrost sensor that can be found near the condenser, in order to make the decision on when to initiate the defrosting cycle.
Some warnings your defrost board is going out
- The system will end up not running due in part to frost blocking the airflow outside
- Defrosting has not run for quite some time even though there is a large amount of frost on the external unit
- The main circuit board may throw a type of error code if the defrost control board fails
