York S1-026-32588-011 Pressure Switch

The York S1-026-32588-011 Pressure Switch is a critical safety component designed for precise airflow monitoring in high-efficiency York gas furnaces. This OEM control is calibrated with a 0.52" WC setpoint and features a Single-Pole Double-Throw (SPDT) configuration, allowing for versatile integration into the system's safety string. It serves as the direct factory replacement for several legacy part numbers, including FS6514-816, RSS-495-167, and NS2-0167-00, ensuring full compatibility with original equipment specifications without the need for field modifications.

Built for the rigors of mechanical rooms, this 0.52 inch water column pressure switch utilizes a 1/4" compression connection for a secure, airtight fit to the probe. For technicians troubleshooting furnace pressure switch failure or 3-red flash codes, verified York HVAC replacement parts like the S1-026-32588-011 restore the combustion air proving circuit to its intended calibration, preventing nuisance trips and ensuring the inducer motor is moving sufficient air before the ignition sequence initiates.

Key Benefits for Contractors

• Exact OEM Calibration: The pre-set 0.52" WC trigger point maintains the manufacturer's safety tolerances for flue gas venting.
• Cross-Compatibility: Seamlessly replaces RSS-495-167 and NS2-0167-00 models, reducing truck stock requirements for York equipment service.
• SPDT Versatility: The Single-Pole Double-Throw switching allows the control board to monitor both the open and closed states of the circuit.
• Durable Construction: Engineered to withstand the heat and vibration of furnace draft inducer housings.
• Leak-Free Seal: The 1/4" compression connection ensures a reliable vacuum signal from the collection box.

Common Questions

Is the S1-026-32588-011 compatible with older RSS-495-167 switches?
Yes, this part number is the current manufacturer-specified replacement for the RSS-495-167 and maintains the identical 0.52" WC rating required for safe operation.

Does this switch resolve a "Pressure Switch Stuck Open" fault code?
If the inducer is running and the vacuum lines are clear of condensate and debris, replacing a faulty switch with this York OEM pressure switch typically resolves the error by restoring the air-proving signal to the control board.

What is the connection type for the vacuum hose?
It utilizes a 1/4" compression connection, which provides a more robust and permanent seal compared to standard slip-on barbed fittings.
