York S1-024-39716-000 Pressure Switch
Maintain precise combustion control and system safety with the York S1-024-39716-000 Pressure Switch. This genuine OEM replacement part is factory-calibrated to a -0.20" WC (Water Column) set point, specifically engineered for induced-draft furnace draft monitoring. As a critical safety interlock, it verifies that the combustion blower is moving sufficient air to exhaust flue gases before allowing the ignition sequence to proceed. It is a direct-fit component for a range of York, Coleman, and Luxaire gas furnaces, featuring a Single-Pole Double-Throw (SPDT) contact configuration for reliable electrical switching under vacuum conditions.
For technicians troubleshooting a "pressure switch stuck open" code, this low-pressure air switch ensures the system meets exact OEM specifications for negative pressure. Its durable diaphragm construction is designed to withstand the heat and cycling of high-efficiency HVAC equipment. Replacing a failed switch with the S1-02439716000 restores proper furnace safety sequence and prevents hazardous back-drafting, ensuring the unit operates only when the correct vacuum is detected.
Key Benefits- Precision Calibration: Factory-set at -0.20" WC to match original equipment requirements for induced-draft systems.
- OEM Compatibility: Guaranteed fit for identified York, Coleman, and Luxaire furnace models, including TM9V and D1NP series.
- Safety Interlock: Prevents gas valve activation if exhaust draft or combustion airflow is insufficient.
- Contractor Grade: Features standard spade terminals and vacuum port connections for efficient field installation.
- Universal Application: Compatible with various induced-draft blower assemblies requiring precise negative pressure sensing.
What causes a -0.20" WC pressure switch to stay open?
Beyond a failed diaphragm, this is often caused by a restricted flue, a clogged collector box port, or a failing inducer motor that isn't pulling enough vacuum to hit the -0.20" WC threshold.
Can I use a switch with a different "WC rating?
No. Pressure switches are safety devices calibrated to the specific venting and airflow design of the furnace. Using a different rating can lead to unsafe operation or frequent lockout codes.
How do I test the S1-024-39716-000?
Use a manometer to verify the inducer is pulling at least -0.20" WC, then check for continuity across the terminals with a multimeter while the fan is running.
