International Comfort Products NTG3125KJA1 Defrost Sensor Board
The defrost sensor control board controls if and when to commence the defrost sequence which aids to keep the outdoor unit free from frost build-up. The control board is influenced by a sensor which is near the condenser somewhere, in order to decide when the defrost cycle should begin.
What symptoms are present when the AC defrost sensor board is in need of replacing?
- The primary control board could throw an error number produced by a failing defrost board
- Defrost mode does not begin even though there is a lot of frost on the unit
- Your HVAC system will stop working due in part to lack of airflow through the outdoor unit
