International Comfort Products GDJ100M12B1 Defrost Sensor Board
The defrost sensor control board initiates the defrost sequence which may be necessary to defrost your outdoor unit. The board looks to a temperature sensor located somewhere by the condenser to make the decision on when to initiate the defrosting cycle.
What happens when my International Comfort Products defrost sensor board has a need to be replaced?
- Defrost mode has not run for quite some time despite that there is a large amount frost in the way
- The HVAC system could cease to operate at all because of frost blocking the fins on the outside unit
- The control board could display a specific error code referring to a failing defrost control board
