York S1-324-35886-000 Pressure Switch Kit

Professional-grade York S1-324-35886-000 Pressure Switch Kit is a critical OEM replacement for 2-stage 96% AFUE furnaces, ensuring precise draft verification for the combustion cycle. This dual-stage inducer pressure switch kit is designed to monitor both low-fire and high-fire manifold pressures, preventing ignition if the venting system fails to achieve the specific inches of water column (WC) required by the control board. For technicians troubleshooting York furnace pressure switch errors, such as a 3-red flash code or a "stuck open" lockout, this genuine factory kit replaces legacy part numbers 150714 and 151062, restoring safe sequences of operation.

Built for the RGF29 series and comparable Johnson Controls equipment, the assembly features high-sensitivity internal diaphragms that resist oxidation and mechanical fatigue. In high-efficiency 96% applications, these switches are essential for detecting blockages in the intake, exhaust, or condensate drain lines that could otherwise lead to dangerous back-drafting. Using this HVAC pressure switch kit ensures your client’s equipment maintains its rated efficiency and safety protocols without the calibration drift often found in generic aftermarket components.

• Exact OEM Calibration: Pre-set to factory specifications for 2-stage 96% systems, eliminating the need for manual field adjustments.
• Broad Compatibility: Direct replacement for York, Luxaire, and Coleman 2-stage furnaces, including part numbers S1-32435886000 and 150714.
• Robust Construction: Engineered to withstand the thermal stress and high humidity typical of high-efficiency 90%+ condensing furnaces.
• Complete Kit: Includes necessary mounting hardware and technical documentation to streamline installation on the draft inducer housing.

• Does this kit resolve 3-flash or 4-flash diagnostic codes? Yes, these codes typically indicate the switch is failing to close or change state upon inducer startup. This kit replaces the faulty sensors to clear those lockouts.
• Is this compatible with single-stage furnaces? No, this is a 2-stage specific kit designed to handle the variable pressures of dual-stage heating modules.
• Can I use this for 80% AFUE models? This kit is specifically calibrated for the higher venting pressures of 96% AFUE condensing systems; always verify your specific model number against the manufacturer data.
