International Comfort Products H2A336GKA200 Defrost Sensor Board
The defrost control board initiates an important defrosting cycle which may be needed in order to keep the outdoor unit free from frost build-up. The defrost sensor board looks to a specific sensor located somewhere by the condenser to ascertain when to begin.
Major signs your defrost board has little life left
- Self defrost sequence does not run especially when there is frost that has built up
- The AC may end up not running due in part to frost blocking the airflow outside
- The main circuit board could display a type of error code produced by a failing defrost board
