Carrier FX4CNF060000 Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrost cycle which helps to keep the outdoor unit free from frost build-up. It is influenced by a defrost sensor located in the outdoor unit to verify when to begin.
Major clues of a weakening defrost sensor board
- The AC may not operate for the simple fact of lack of airflow through the outdoor unit
- The main circuit board could throw a type of error code referring to a bad defrost board
- Defrosting does not begin even though there is a lot of frost that makes the unit run like crap
