International Comfort Products CAC442AKA1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin an important defrosting cycle which actually helps to get rid of the frost that collects on the outdoor unit. The control board relies on a defrost sensor which is near the condenser somewhere, in order to ascertain when to initiate the defrosting cycle.
Warnings your outdoor defrost sensor board is in need of replacing
- Defrost mode will not kick in despite that there is a large amount frost in the way
- The primary control board may show an error signal when encountering a problem
- Your system could not work due in part to the amount of frost on the outdoor unit
