International Comfort Products PGC024K040A Defrost Sensor Board
The defrost sensor board will begin the defrosting phase in order to keep your outdoor unit from plugging up. The control board looks to a sensor which is near the condenser somewhere, in order to verify when the defrost cycle should begin.
Simple signals your defrost board will eventually need to be replaced
- Defrost session never initiates even though there is a large amount of frost that makes the unit run like crap
- The main control board may throw a specific error code if the defrost board fails
- Most systems will not operate due in part to frost blocking the fins on the outside unit
