International Comfort Products NTP6050FBA1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrosting phase in order to keep your outdoor unit from plugging up. The board depends on a specific sensor which is near the condenser somewhere, in order to agree when to begin.
What red flags are there that my International Comfort Products defrost sensor board is dying?
- Air conditioning may stop working due to lack of airflow through the outdoor unit
- The control board may show an alphanumeric error code produced by a failing defrost board
- Self defrost sequence never begins even though there is quite a bit frost that needs to be removed
