York S1-024-35274-000 Pressure Switch

The York S1-024-35274-000 Pressure Switch is a critical safety component engineered for precise airflow monitoring in high-efficiency York, Coleman, and Luxaire gas furnaces. This OEM York furnace pressure switch features a Single Pole Normally Open (SPNO) configuration and is factory-calibrated to a -.2/-.4 inch water column set point. Designed as a close-on-fall air pressure switch, it ensures the draft inducer motor is moving sufficient combustion air before allowing the ignition sequence to proceed, preventing dangerous furnace operation during venting blockages or motor failure.

Constructed for professional-grade reliability, this HVAC inducer pressure switch (MPN S1-02435274000) provides a direct fit for 2-stage variable speed downflow and horizontal units, including models like the PV8B16N080DH11D. By maintaining exact draft inducer pressure switch tolerances, it protects the heat exchanger from overheating and ensures consistent burner performance. For any York S1-024-35274-000 replacement, verify the pressure rating on the existing body to ensure system compatibility with the original manufacturer specifications.

• OEM Precision: Genuine York S1-024-35274-000 replacement ensures exact set points for factory safety compliance.
• Enhanced Safety: The SPNO close on fall logic prevents gas valve activation if the flue pipe is obstructed or the inducer fails.
• Universal Compatibility: Fits a wide range of York, Coleman, and Luxaire residential gas furnace models.
• Rugged Construction: Built to withstand the high-temperature environment of the combustion chamber area.

• Why is my furnace failing to ignite? A faulty S1-024-35274-000 pressure switch often prevents the igniter from glowing if it fails to sense the required negative pressure.
• Does this switch work on 2-stage furnaces? Yes, this specific model is optimized for 2-stage variable speed furnaces requiring a -.2/-.4 WC rating.
• Can I use a universal pressure switch instead? Using the OEM York pressure switch is recommended to ensure the specific inches of water column calibration matches your unit's safety profile.
