Description
The York S1-024-35903-000 is a genuine OEM dual-setpoint pressure switch engineered for precise pressure sensing in York heating systems. With factory-calibrated setpoints of .45″ WC and .85″ WC, this switch monitors the pressure differential produced by the inducer assembly to verify proper venting and combustion airflow before allowing the burners to fire — a critical safety function in modern induced-draft and condensing furnaces.
As a direct OEM replacement, this pressure switch is designed to fit and function exactly as the original component, eliminating guesswork and ensuring compatibility with your York equipment. Choosing a genuine York part means you get the same quality, reliability, and performance as the factory-installed component.
