York S1-5992116 Pressure Switch

The York S1-5992116 Pressure Switch is a critical safety component designed for precise monitoring of pressure differentials within the combustion blower or inducer motor assembly. This specific HVAC draft inducer switch is calibrated to trip at 0.625" WC / 0.525" WC, ensuring that the furnace or air handler maintains proper venting before the ignition sequence initiates. As a direct replacement for obsolete part S1-025-38728-000, this OEM component ensures a drop-in fit for compatible York, Luxaire, and Coleman gas-fired equipment, eliminating the need for field modifications or bracket adjustments. For technicians troubleshooting a furnace pressure switch stuck open or closed, the S1-5992116 provides the reliable set-points necessary to prevent nuisance tripping and ensure consistent furnace sequence of operation. This dual-action switch utilizes high-grade diaphragm materials to withstand fluctuating flue temperatures and corrosive combustion byproducts, maintaining system integrity even in high-cycle residential applications.

• Direct Replacement: Replaces S1-025-38728-000 without requiring wiring harnesses or pressure line extensions.
• Precision Calibration: Factory-set at 0.625" and 0.525" WC to match the original manufacturer specifications for proper airflow verification.
• Durable Construction: Engineered to resist diaphragm fatigue, reducing callbacks related to York furnace pressure switch errors.
• Broad Compatibility: Standard 1/4 inch spade terminals allow for seamless integration with existing control board lead wires.

What are the symptoms of a failing York S1-5992116?
Common indicators include the inducer motor running continuously without the burner igniting, or the control board throwing a 2-flash or 3-flash code indicating the pressure switch failed to close.

Can this pressure switch be field-calibrated?
No. Pressure switches are factory-calibrated safety devices. Attempting to adjust the set-point can lead to unsafe combustion conditions or carbon monoxide leaks.

How do I verify if the S1-5992116 is the correct part for my unit?
Technicians should cross-reference the WC ratings on the existing switch's label or consult the specific unit parts list to ensure it matches the 0.625/0.525 specification.
