International Comfort Products NDN6100GFG1 Defrost Sensor Board
The defrost control board will begin the defrost sequence which actually helps to get rid of the frost that collects on the outdoor unit. The board looks to a sensor located somewhere by the condenser to decide when to begin.
Indications of a worsening International Comfort Products defrost sensor board
- The whole system may stop working due in part to lack of airflow through the outdoor unit
- Defrosting will not kick in even though there is quite a bit frost on the outdoor unit
- The HVAC system control board could display a particular error code produced when the defrost control board fails to receive a signal
