International Comfort Products PGF036L100F Defrost Sensor Board
The defrost control board determines when or if to start the defrost sequence in order to rid your unit of frost that can build up. It relies on a sensor which is near the condenser somewhere, in order to determine when to begin.
Red flags of a poorly performing International Comfort Products defrost sensor board
- The HVAC system control board might issue a specific error code when the defrost control board refuses to initialize properly
- The HVAC system could not operate due to the fact of the frost blocking the flow of air
- Defrosting never begins even though there is quite a bit frost on the external unit
