International Comfort Products GDJ050M12C1 Defrost Sensor Board
The defrost control board instructs the system to activate the defrosting phase in order to defrost your outdoor unit. The board depends on a sensor located in the outdoor unit to agree when the defrost cycle should begin.
What are the indications that my defrost sensor board is about to go out?
- Defrost mode never initiates despite the fact that there is a lot of frost that makes the unit run like crap
- Your HVAC system will cease to operate for the simple fact of frost blocking the airflow outside
- The HVAC system control board may signify an error code produced when the defrost board is bad
