Carrier 38CKC042 Defrost Sensor Board
The defrost sensor control board instructs the system to activate an important defrosting cycle which aids to rid your unit of frost that can build up. The defrost sensor board looks to a specific sensor located near the condenser to verify when to initiate the defrosting cycle.
Indications your defrost board is not going to last much longer
- The primary control board may issue an error number produced by a bad defrost control board
- Unit defrost session never kicks in even though there is a large amount of frost that needs to be removed
- The system will cease to operate at all because of lack of airflow through the outdoor unit

You do not need to install the replacement part alone. Search for a pro in your area to do the job for you.
