International Comfort Products CHP230GKA1 Defrost Sensor Board
The defrost sensor board determines when or if to start the defrost cycle which aids to keep your outdoor unit from plugging up. It looks to a specific sensor that can be found near the condenser, in order to agree when the defrost cycle should begin.
Major clues the AC defrost sensor board will not last the year
- Defrost session never initiates especially when there is a rather large amount of frost that makes the unit run like crap
- The whole system may not work for the simple fact of lack of airflow through the outdoor unit
- The main board may throw an error code produced by a failing defrost board
