York S1-024-36052-007 Pressure Switch This 10-pack of Mars resistorsThe York S1 024 36052 007 is a critical safety component designed for precise vent pressure monitoring in residential gas furnaces. Rated at 0. 71 IWC (Inches Water Column), this differential air pressure switch ensures the draft inducer motor is moving sufficient combustion air before allowing the ignition sequence to proceed. As a veteran tech knows, a failed pressure switch is often a symptom of blocked venting, a restricted heat exchanger, or a
