International Comfort Products GPFM24K060F Defrost Sensor Board
The defrost sensor board determines when or if to start the defrosting phase which aids to keep your outdoor unit from plugging up. The control board depends on a temperature sensor located somewhere by the condenser to make the decision on when to initiate the defrosting cycle.
Signs your defrost board will die soon
- Your HVAC system will stop functioning for the simple fact of lack of airflow through the outdoor unit
- The defrost feature refuses to run even though there is quite a bit frost built up
- The main control board might give out an error number produced when the defrost control board fails to receive a signal
