York S1-024-39490-000 Pressure Switch no continuity typically indicates aThe S1 024 39490 000 is a factory caliber York pressure switch engineered to monitor vital air pressure differentials within the combustion blower assembly. This 0. 26 WC pressure switch acts as a primary safety limit, confirming that the inducer motor is exhausting flue gases effectively before allowing the gas valve to energize. Built as a furnace pressure switch replacement, this component is the direct functional successor to the 024 27557 000,
