Description
Ensure safe and efficient furnace operation with the York S1 024 39706 000 — a certified OEM furnace air pressure switch designed for reliable venting and combustion safety verification.
Key Features
- Precision pressure switch action — The switch closes (or remains normally open until activation) at a vacuum level around 0.10" WC, verifying that the inducer/fan is drawing proper airflow before allowing ignition, helping prevent improper combustion or flue gas venting.
- OEM approved reliability — Manufactured to meet original York (and related Luxaire / Coleman) furnace specifications, ensuring a drop in fit and seamless replacement without modification.
- Simple two terminal wiring + single hose port — Installation is straightforward: connect the pressure hose and wiring terminals, then install — ideal for maintenance or retrofit jobs.
- Critical for safe furnace operation — By verifying vent airflow before ignition, the switch helps prevent hazardous conditions such as improper flue gas blowback or incomplete combustion.
