York S1-024-34562-000 Pressure Switch

The York S1-024-34562-000 Pressure Switch is a critical OEM replacement part engineered specifically for high-efficiency York furnace and air handler applications. This dual pressure switch features a normally open (N/O) contact configuration, calibrated with a 1.05 / -0.40 deactivation rating to monitor venting and combustion air pressure accurately. When the S1-024-34562-000 detects a drop in static pressure or an obstruction in the flue, it breaks the circuit as a primary safety protocol, preventing the ignition of the gas valve under unsafe conditions.

For technicians servicing York HVAC systems, using this genuine York part ensures the system stays within the manufacturer's specified internal static pressure parameters. The rugged construction resists diaphragm fatigue, a common cause of nuisance trips in residential and light commercial units. Whether you are addressing "limit switch open" fault codes or performing seasonal HVAC maintenance, this dedicated pressure sensor provides the precise set points required to maintain equipment uptime and safeguard against CO risks associated with improper venting.

Technical Benefits for Contractors

• Precise Calibration: Factory-set 1.05 / -0.40 deactivation points eliminate the need for field adjustments and reduce callbacks.
• OEM Reliability: Built to original York engineering standards for direct drop-in compatibility with furnace pressure switch mounts.
• Safety Assurance: Provides consistent monitoring of inducer motor performance and flue integrity.
• Enhanced Durability: Tested for high-cycle longevity in demanding thermal environments to prevent premature diaphragm failure.

Common Questions

What is the purpose of the dual pressure configuration on the S1-024-34562-000?
This switch monitors two distinct pressure thresholds, often used to verify both the initial pull of the inducer motor and the sustained static pressure during the heating cycle to ensure the system is venting safely.

Can I use a universal pressure switch instead of the York S1-024-34562-000?
Universal switches often require manual calibration and may not match the specific 1.05 / -0.40 deactivation curve required for York systems. Using the OEM part ensures the safety circuit functions exactly as designed by the factory.

How do I diagnose a faulty York S1-024-34562-000?
Check for continuity across the terminals when the inducer motor is running. If the switch remains open despite the inducer reaching full RPM and the tubing being clear, the internal diaphragm or contacts may have failed.
