Carrier 38BRC048 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrost cycle which aids to continue normal heating and cooling operations. The defrost board relies on a sensor located near the condenser to decide when the defrost cycle should begin.
What are the clues to watch out for to know my outdoor defrost sensor board is almost dead?
- The HVAC system control board may show an error number produced when the defrost board is bad
- The AC may stop working for the simple fact of frost blocking the airflow outside
- Self defrost sequence refuses to initiate despite that there is a large amount frost that has built up
