York S1-026-32264-001 Pressure Switch

The York S1-026-32264-001 is an OEM-certified 1.25" WC pressure switch engineered to maintain critical safety standards in residential gas furnaces. This SPST (Single Pole Single Throw) air pressure sensor acts as a direct replacement for S1-026-32263-001, providing a precise drop-in solution for York, Coleman, and Luxaire HVAC systems. In high-efficiency combustion setups, this switch monitors the negative pressure generated by the inducer motor, ensuring the flue is clear before ignition. When performing furnace pressure switch troubleshooting, this factory-calibrated component ensures the control board receives an accurate signal at the required 1.25 inches of water column. Its robust diaphragm design is built to withstand the heat cycles of a standard cabinet, preventing nuisance trips and lockouts. For field technicians, using this specific HVAC pressure switch SPST ensures compliance with the original manufacturer specifications, maintaining the integrity of the combustion sequence and airflow verification system without the need for field adjustments or bracket modifications.

Key Benefits

• Direct OEM Specification: Verified replacement for S1-026-32264-001 and S1-026-32263-001 to ensure factory-correct performance.
• Accurate Pressure Detection: Calibrated to 1.25" WC to prevent ignition if the venting system or inducer motor is underperforming.
• Simplified Installation: Standard SPST terminal configuration allows for rapid connection to existing wiring harnesses.
• Reliable Safety Integration: Monitors for blocked vents or failed blowers to prevent hazardous combustion conditions.

Common Questions

What replaces York S1-026-32263-001?
The S1-026-32264-001 is the certified successor and direct physical replacement for the older -001 model.

How to test a York furnace pressure switch?
Disconnect power, use a manometer to verify the inducer is pulling at least 1.25" WC, and check for continuity across the contacts once the required pressure is reached.

Why is my furnace pressure switch stuck open?
This often results from a restricted flue, a clogged collector box port, or moisture in the pressure tubing, though a ruptured internal diaphragm can also prevent the switch from closing.
