York S1-024-35283-000 Pressure Switch

The York S1-024-35283-000 Pressure Switch is a critical safety and operational component designed for high-precision monitoring in York, Coleman, and Luxaire HVAC systems. This OEM replacement pressure switch is factory-calibrated to a -0.35" WC setpoint, ensuring the inducer motor is moving sufficient combustion air before ignition. Featuring a Single Pole Single Throw (SPST) contact configuration and a 1/4" barbed connection, it provides a secure, leak-proof interface with the vacuum tubing. As a dual air pressure switch, it often functions in 2-stage systems to verify proper venting across varying furnace cycles. When troubleshooting a furnace pressure switch stuck open or restricted flue code, this 0.35 inch WC pressure sensor offers the exact pneumatic specifications required to restore factory system logic. Engineered for thermal stability and vibration resistance, the S1-024-35283-000 maintains HVAC pressure switch calibration under extreme furnace cabinet temperatures, preventing nuisance trips and ensuring reliable proof-of-closure for the control board.

• OEM Precision: Direct York S1-024-35283-000 replacement ensures exact -0.35" WC trip points without the need for manual adjustment.
• Reliable Connectivity: Standard 1/4 inch barbed fitting allows for quick integration with existing silicone or rubber vacuum hoses.
• Rugged Construction: Designed as an industrial air pressure switch to withstand the high-cycle demands of residential and light commercial furnaces.
• System Safety: Crucial for detecting blocked vents or inducer blower failure, protecting heat exchangers from overheating.

What causes a York pressure switch to fail?
Most failures result from diaphragm degradation, moisture buildup in the vacuum line, or pitted internal SPST contacts. If the inducer is running but the switch does not close, verify the -0.35" WC threshold with a manometer.

Is this switch field-adjustable?
No. This is a factory-set -0.35" WC pressure switch. Attempting to adjust the setpoint can lead to unsafe combustion conditions and system lockout.

Will this work with other brands?
While functionally similar to other switches, it is specifically designed for York S1-024-35283-000 specifications. Always check your furnace model number to ensure the WC rating matches the original equipment manufacturer requirements.
