York S1-024-35265-000 Pressure Switch

Maintain critical system geometry and combustion safety with the York S1-024-35265-000 Pressure Switch. This genuine Source1 OEM replacement is engineered for multi-stage gas furnaces, functioning as a high-fire inductive load sensor within the draft inducer circuit. Calibrated to a .55/1.2" WC set point, this SPNO (Single Pole Normally Open) switch is designed to close on a fall in pressure, ensuring the inducer motor maintains the required static vacuum for safe flue gas venting before ignition.

Built to withstand the thermal cycling typical of York, Coleman, and Luxaire residential heating units, the S1-02435265000 provides precise HVAC pressure monitoring. Its rugged diaphragm construction and silver-plated contacts prevent common nuisance trips caused by switch bounce or oxidation. For technicians performing furnace troubleshooting, this component ensures backward compatibility with existing draft logic systems, replacing legacy 024-35265-000 controls. It is a direct-fit solution for model FL9V060B12UP11C and similar high-efficiency furnace series.

Key Benefits for the Jobsite

• OEM Calibration Maturity: Pre-set at .55/1.2" WC to match York’s factory combustion specifications.
• Circuit Integrity: SPNO (Normally Open) configuration closes on pressure drop to verify inducer performance.
• Broad Compatibility: Universal replacement for York Coleman Luxaire pressure controls and SKU 208Z56.
• Durable Termination: Standard male spade terminals for high-conductivity connections in high-vibration environments.
• Enhanced Safety: Prevents gas valve energization if the venting system is obstructed or the inducer motor fails.

Common Questions

Is this switch compatible with 2-stage furnaces?
Yes, the York S1-024-35265-000 is frequently used in 2-stage systems to monitor specific pressure thresholds required for high-fire operation.

What does 'Close on Fall' mean for this part?
This technician-specified setting means the internal contacts complete the circuit when the sensed pressure drops to the calibrated set point (fall), typically signifying the inducer is creating the necessary vacuum.

Can I use this as a substitute for a generic universal pressure switch?
While universal kits exist, using this genuine York pressure switch ensures the set points exactly match the manufacturer's safety sequence, preventing lockout issues common with non-OEM parts.
