International Comfort Products CAC018AKA1 Defrost Sensor Board
The defrost sensor control board will determine when to initiate an important defrosting cycle which actually helps to remove frost build-up that may accumulate. The defrost board relies on a defrost sensor located in the outdoor unit to determine when the defrost cycle should begin.
Hints the defrost sensor board needs replacing
- The defrost feature never initiates despite that there is a large amount frost on the outdoor unit
- The system will not operate due in part to too much frost
- The HVAC system control board may throw a particular error code if the defrost board fails
