International Comfort Products PGF036S100F Air Pressure Switch
The main job of the pressure switch is to sense if the air blower is circulating the air as it should. The majority of pressure switches have a manual reset feature, from which it would have to be reset manually in order for the HVAC system to continue running. This switch is one of the vitally important safety devices that are created to keep everyone in the house safe.
