York S1-024-35270-000 Pressure Switch Technicians should verify manifold pressureThe York S1 024 35270 000 Pressure Switch is a critical safety component designed for specific York, Luxaire, and Coleman furnace models. Operating as a SPNO (Single Pole Normally Open) switch, it is calibrated to a . 45" WC set point, closing on a fall in pressure. This HVAC inducer pressure switch ensures the draft inducer motor is moving sufficient air through the heat exchanger before the ignition sequence begins, preventing hazardous combustion
