International Comfort Products PGAA30C1K6 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrosting phase if necessary, to rid your unit of frost that can build up. The defrost sensor board is relayed information from a specific sensor that can be found near the condenser, in order to determine when to begin.
Major signs your outdoor defrost sensor board is in dire straights
- The main control board could display a particular error code when the defrost control board refuses to initialize properly
- The defrost feature will not kick in especially when there is a rather large amount of frost built up
- Your HVAC system will end up not running at all because of frost blocking the fins on the outside unit
