International Comfort Products GPSM36L100F Defrost Sensor Board
The defrost control board will determine when to initiate the defrost cycle which may be needed in order to continue normal heating and cooling operations. The defrost sensor board is influenced by a sensor located somewhere by the condenser to decide when to initiate the defrosting cycle.
Some clues your International Comfort Products defrost sensor board is on its last leg
- The whole system may not operate due in part to too much frost
- Defrosting never kicks in despite the fact that there is quite a bit frost on the external unit
- Your main control board could display an alphanumeric error code when encountering a problem
