International Comfort Products CAC448GKA1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost sequence which helps to keep the outdoor unit free from frost build-up. The control board is relayed information from a defrost sensor located near the condenser to ascertain when to initiate the defrosting cycle.
Important signs your outdoor defrost sensor board has very little life left
- Defrost session has not run for a while even though there is a large amount of frost in the way
- The main control board may issue an error signal produced when the defrost control board fails to receive a signal
- Most systems will end up not running due to the fact of frost blocking the airflow outside
