York S1-1474-051P HSI Ignitor

Maximize the reliability of your gas-fired heating systems with the York S1-1474-051P HSI Ignitor. This OEM hot surface igniter is engineered for a direct fit in residential and commercial York, Coleman, and Evcon furnaces, specifically designed for GMB and BGM series 4-position HSI units. Constructed from high-purity silicon carbide, this 120V component provides rapid heat-up and stable electrical resistance, ensuring consistent burner ignition even in high-demand environments. As a critical furnace replacement part, it features 18-inch insulated lead wires with 1/4-inch quick-connect terminals for seamless HVAC 120V igniter integration. This hot surface ignition element is a robust solution for correcting common lockout or ignition failure codes in modern high-efficiency systems. To maintain the integrity of the element, ensure you handle the unit only by the ceramic base, as skin oils can create hot spots that lead to premature failure during high-temperature cycles.

• Precision Compatibility: Serves as a genuine OEM replacement for York S1-1474-051P, cross-referencing with various Coleman and Evcon manufactured housing furnaces.
• High-Temperature Durability: Leveraging silicon carbide construction for superior thermal strength and resistance to oxidation in the burner flame.
• Contractor-Ready Installation: Features 18-inch high-temperature fiberglass insulated leads and standard 1/4-inch terminals for a rapid swap-out.
• Consistent Performance: Engineered to provide a reliable ignition spark or glow, minimizing gas valve recycling and improving system efficiency.

How do I test if my York S1-1474-051P ignitor is bad?
Using a multimeter set to ohms, check for continuity across the two lead terminals. A functional furnace ignitor typically shows a resistance reading between 30 and 200 ohms; a reading of "infinite" or zero indicates the element is cracked and requires immediate replacement.

Can I touch the ignitor element during installation?
No. You must only handle the hot surface igniter by its ceramic mounting block. Touching the gray silicon carbide element transfers skin oils, which concentrate heat and cause the part to fail prematurely when energized.

Which furnace models use the S1-1474-051P?
This HVAC heating part is commonly found in York GMB05012AXU models and various BGM series gas furnaces. It is frequently used in 4-position heating units that require a specific 120V ignition sequence.
