International Comfort Products NTC6125KJG1 Defrost Sensor Board
The defrost control board determines when or if to start the defrosting phase which may be needed in order to keep the outdoor unit free from frost build-up. The control board is influenced by a defrost sensor that can be found near the condenser, in order to agree when the defrost cycle should begin.
What are the indications that my defrost board is about to go out?
- Your HVAC system will not operate due to frost blocking the airflow outside
- The defrost feature never begins especially when there is frost on the unit
- The control board might give out a specific error code produced when the defrost control board fails to receive a signal
