Carrier FE4ANB006000AAAA Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin an important defrosting cycle which may be necessary to keep the outdoor unit free from frost build-up. The defrost sensor board depends on a sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
Major clues of an inadequate outdoor defrost sensor board
- The HVAC system could stop running at all because of frost blocking the airflow outside
- The defrost sequence refuses to run even though there is a large amount of frost on the unit
- The main control board may issue an error code referring to a failing defrost control board
