International Comfort Products CAC248GKA1 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrost cycle which may be necessary to keep your outdoor unit from plugging up. The defrost sensor board looks to a specific sensor located somewhere by the condenser to determine when the defrost cycle should begin.
What to see if the AC defrost sensor board is crapping out?
- Defrost session never runs even though there is a lot of frost on the unit
- The system may stop working due in part to the fact that there is too much frost
- The HVAC system control board may throw a specific error code referring to a bad defrost board
