York S1-024-39718-000 Switch
The York S1-024-39718-000 is an OEM two-stage pressure switch designed for precision air-flow monitoring in high-efficiency furnace systems. This 0.90" WC pressure switch serves as a critical safety component, ensuring the draft inducer motor is generating the required vacuum pressure before the ignition sequence initiates. Specifically engineered for York, Coleman, and Luxaire gas furnaces, this high-fire switch prevents hazardous conditions like improper venting or incomplete combustion by interlocking with the control board.
Built for long-term reliability in demanding HVACR environments, the S1-024-39718-000 features a factory-calibrated set point of 0.9 in-WC. This 2nd-stage sensor provides accurate feedback during high-heat operation, maintaining system integrity even during fluctuating atmospheric conditions. Veterans in the field recognize this Source 1 HVAC part as the exact replacement for failing switches that typically trigger 3-flash or 4-flash diagnostic codes on Integrated Furnace Controls (IFC). Ensure your manifold pressure and inducer RPM are within spec before replacing to avoid nuisance trips from underlying mechanical issues.
Key Benefits:- OEM Compatibility: Guaranteed fit and function for York, Luxaire, and Coleman 2-stage furnaces.
- Precision Calibration: Pre-set at 0.90 in-WC to meet 2nd-stage high-fire safety requirements.
- Durable Construction: Designed to withstand high-temperature cycles and consistent diaphragm actuation.
- Safety Interlock: Crucial for preventing ignition during blocked vents or inducer motor failure.
- How do I know if my York pressure switch is bad? Technicians often look for diagnostic codes (like 3 red flashes) indicating the S1-024-39718-000 is stuck open or closed. Use a manometer to verify the inducer is pulling at least 0.90" WC before condemning the part.
- Can I use a single-stage switch as a replacement? No. This is a 2-stage pressure switch specifically calibrated for the high-fire sequence; swapping it for a single-stage component will compromise system safety and lead to permanent lockouts.
- Is this switch for the inducer or the collector box? This specific model is typically utilized as the high-fire inducer pressure switch in multi-stage heating systems.
