International Comfort Products CHP224AKA1 Defrost Sensor Board
The defrost sensor control board will begin the defrosting phase which aids to get rid of the frost that collects on the outdoor unit. The board depends on a sensor which is near the condenser somewhere, in order to ascertain when the defrost cycle should begin.
Major indications of an unhealthy AC defrost sensor board
- The main board might give out an alphanumeric error code produced when the defrost board is bad
- The system may not run due to the fact of the amount of frost on the outdoor unit
- The defrost feature never initiates even though there is a lot of frost on the unit
