York S1-024-36052-007 Pressure Switch

The York S1-024-36052-007 is a critical safety component designed for precise vent pressure monitoring in residential gas furnaces. Rated at 0.71 IWC (Inches Water Column), this differential air pressure switch ensures the draft inducer motor is moving sufficient combustion air before allowing the ignition sequence to proceed. As a veteran tech knows, a failed pressure switch is often a symptom of blocked venting, a restricted heat exchanger, or a failing inducer, but when the switch itself drifts out of calibration, a direct OEM replacement is the only way to restore reliable operation.

This Source 1 service part is the direct replacement for S1-024-23278-700 and FS6342-518, maintaining the exact 0.71" WC trip point required for York, Coleman, and Luxaire systems. It features a normally open (NO) contact configuration that closes upon sensing the correct negative pressure. When troubleshooting sequence of operation failures or flash code 3 errors, use a manometer to verify the inducer pull exceeds the setpoint before condemning the switch. This OEM furnace part is built to handle the cycling demands of high-efficiency systems and prevents unsafe combustion conditions caused by ventilation restrictions.

• Direct OEM Cross-Reference: Expertly replaces legacy part numbers S1-024-23278-700 and FS6342-518 without modification.
• Precise Setpoint Accuracy: Factory-calibrated to 0.71 IWC to meet strict furnace safety standards and prevent nuisance trips.
• Universal Compatibility: Designed for use across a wide range of York, Coleman, and Luxaire gas furnaces.
• Durable Construction: Engineered to withstand moisture and heat common in high-efficiency venting environments.

• Can I use an adjustable switch instead of the 0.71 IWC? It is best practice to use the specific OEM pressure switch to ensure the system operates within its designed safety parameters.
• What causes a "Pressure Switch Stuck Open" error? While it could be a faulty switch, always check for clogged condensate drains, cracked pressure tubing, or beehives in the vent termination first.
• Does this include the tubing? This part is the pressure switch assembly; existing silicone tubing should be inspected for cracks and reused or replaced separately.
