International Comfort Products NDN5125BKC1 Defrost Sensor Board
The defrost sensor board initiates an important defrosting cycle in order to rid your unit of frost that can build up. The board depends on a specific sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
What to see if the outdoor defrost sensor board is on its last leg?
- Defrosting refuses to initiate even though there is excessive frost that has built up
- Most systems will cease to operate due in part to the safety features installed
- The main control board could display an alphanumeric error code if the defrost control board fails
