York S1-024-25006-703 Pressure Switch

The York S1-024-25006-703 Pressure Switch is a mission-critical safety component designed for precise furnace pressure monitoring in York, Coleman, and Luxaire HVAC systems. Engineered as a genuine OEM replacement part, this switch is factory-calibrated to a .90" WC pressure rating, ensuring your burner assembly and inducer motor function within the tight tolerances required by high-efficiency gas furnaces. A failed draft inducer switch often leads to ignition lockout; replacing it with this robust, industrial-grade assembly restores the necessary safety handshake between the air pressure switch and the control board.

Field-tested for long-term reliability, the S1-024-25006-703 features a high-sensitivity diaphragm housed in a durable casing to resist the thermal stresses of repeated cycling. This HVAC pressure switch is essential for verifying proper venting and draft through the heat exchanger, preventing dangerous flue gas accumulation. Its direct-fit design simplifies the swap-out process for service technicians, utilizing standard spade terminals for rapid electrical connection. For consistent gas furnace repair results, installing the correct water column spec is non-negotiable to maintain system certification and operational safety.

• Precise Calibration: Factory-set at .90" WC to match specific manufacturer venting requirements.
• OEM Engineering: Ensures exact physical and electrical compatibility with York P2UDD20P13301A and related series.
• Rugged Construction: Built to withstand commercial and residential furnace environment vibrations and temperatures.
• Safety Compliance: Crucial for detecting inducer fan failure or blocked vent conditions to trigger system shutdown.

• Can I use a switch with a different WC rating? No. Using a switch with a different pressure setting can lead to unsafe combustion conditions or frequent nuisance trips. Always match the .90" WC specification.
• How do I verify if the switch is the problem? Use a manometer to check actual inducer draft against the .90" WC setpoint and a multimeter to check for continuity across the terminals when the draft is established.
• What causes these switches to fail? Diaphragm fatigue, moisture in the sensing lines, or heat-related scale buildup on the internal contacts are common failure points in older units.
