York S1-024-25329-706 Pressure Switch

The York S1-024-25329-706 Pressure Switch is a mission-critical safety component designed for precise monitoring of pressure differentials within residential and light commercial HVAC systems. This SPNO (Single Pole Normally Open) switch is factory-calibrated to a 1.6" WC setpoint, specifically engineered to close on fall. This ensures that the furnace inducer motor provides sufficient draft for safe combustion before allowing the ignition sequence to proceed. As a genuine OEM York replacement part, it ensures direct physical and electrical compatibility with specifically matched furnace cabinets, eliminating the risks associated with universal "one-size-fits-all" pressure switches. The durable diaphragm construction and corrosion-resistant housing are designed to withstand high-cycle operations in demanding environments. Technicians should verify water column (WC) ratings and mounting orientation during installation to ensure a proper seal and accurate draft pressure sensing, maintaining the integrity of the furnace safety circuit and preventing intermittent lockouts or inducer motor performance issues.

• Precision Calibration: Factory-set at 1.6" WC for exact draft pressure verification.
• OEM Integrity: Dedicated York S1-024-25329-706 specifications ensure exact terminal alignment and mounting footprint.
• SPNO Logic: Reliable close-on-fall mechanism ensures the system only fires under optimal venting conditions.
• Enhanced Durability: Engineered to handle the thermal fluctuations and moisture typical of high-efficiency condensing furnaces.

What causes a pressure switch fault code on a York furnace?
A lockout is typically triggered by a restricted vent pipe, a failing inducer motor, clogged condensate drains, or a ruptured diaphragm within the S1-024-25329-706 itself.

Can I adjust the setpoint on this pressure switch?
No. This is a factory-calibrated fixed pressure switch. Attempting to adjust the 1.6" WC setting will compromise equipment safety and void the technical certification of the furnace.

Is the S1-024-25329-706 compatible with other brands?
While it may fit some Luxaire or Coleman units sharing the same Source 1 platform, always cross-reference the OEM part number against the specific model serial plate to ensure proper pressure differential response.
