York S1-024-36052-020 Pressure Switch

The York S1-024-36052-020 Pressure Switch is a critical dual-stage safety component engineered for precision monitoring of inducer motor performance and flue vacuum integrity. This OEM York replacement part features a dual-setpoint configuration with a 0.45" WC low-fire trip and a 1.0" WC high-fire threshold. Designed as the direct replacement for 024-27662-001, it ensures seamless compatibility with multi-stage York, Coleman, and Luxaire gas furnaces. The normally open (N/O) pressure switch construction utilizes a high-sensitivity diaphragm to verify proper combustion air flow before allowing the ignition sequence to proceed. As a veteran-grade HVAC furnace air pressure switch, it provides the reliability needed to prevent unsafe venting conditions and nuisance code lockouts in high-efficiency systems.

• Precise Dual-Stage Calibration: Pre-set at 0.45" and 1.0" WC to maintain exact vacuum specifications for multi-stage heating cycles.
• Seamless OEM Integration: Engineered to match the footprint and electrical terminals of the 024-27662-001 for fast, drop-in replacement.
• Enhanced Safety Logic: Prevents furnace operation if the inducer motor fails to reach necessary RPM or if flue venting becomes obstructed.
• Durable Construction: Built to withstand the high-temperature environments of modern furnace cabinets without setpoint drift.

Is the S1-024-36052-020 compatible with my older 024-27662-001 switch?
Yes, this is the official factory-authorized superseding part number specifically designed to replace the 024-27662-001 without modification.

Why is my furnace tripping on a pressure switch error code?
Common causes include a failing inducer motor, blocked chimney/vent pipes, a cracked heat exchanger, or a ruptured diaphragm within the switch itself. Always test vacuum pressure with a manometer before replacing.

Does this switch come with a new sensing tube?
This is the switch assembly only. We recommend inspecting your existing silicone tubing for cracks or moisture buildup during installation to ensure accurate pressure readings.
