The York S1-373-31175-000 Ignitor Kit is a genuine Source 1 OEM replacement engineered for precise ignition in residential and light commercial gas-fired furnaces. This kit, which includes the ignition electrode and high-temp lead assembly, is designed to withstand the extreme thermal cycling typical of modern heating systems. Field technicians rely on this furnace ignitor kit to restore consistent burner ignition and prevent nuisance lockouts caused by carbon buildup or element degradation. Built to strict factory tolerances, the S1-37331175000 ensures proper alignment with the burner carryover tube, facilitating a clean light-off sequence. It is compatible with select York, Coleman, and Luxaire systems, specifically replacing older spark or hot surface configurations as specified in unit service manuals. For contractors, using this HVAC repair part ensures OEM ignition compatibility and long-term reliability without the fitment issues common to universal alternatives. Always handle the ceramic insulator with care to avoid hairline fractures during installation.

• OEM Direct Fit: Eliminates mounting modifications and ensures correct spark gap for reliable burner combustion.
• Thermal Resilience: Constructed with high-grade alloys and ceramic to resist oxidation and crack-failure under high heat.
• System Efficiency: Restores factory-spec start-up timing, reducing gas delay and optimizing system heating cycles.
• Broad Compatibility: Services a wide range of York-family equipment, making it a critical stock item for service vans.

What are the signs that I need to replace my York S1-373-31175-000?
If the furnace is clicking but failing to ignite, or if you observe visible cracks in the ceramic insulator or significant pitting on the electrode tip, the ignitor is likely failing and needs immediate replacement.

Is the ignition cable included in this specific kit?
Yes, this ignitor kit includes the necessary cable assembly to ensure a secure electrical connection from the ignition control board to the electrode.

Can I use a universal ignitor instead of the S1-37331175000?
While universal parts exist, they often lack the precise positioning required for York gas furnace ignition, which can lead to delayed ignition or repeated system lockout codes. This OEM kit is the recommended professional solution.
