York S1-025-21706-702 Ignition Cable

The York S1-025-21706-702 Ignition Cable is a critical high-tension lead designed for precise spark delivery in residential and commercial heating systems. Engineered as a direct OEM furnace replacement part for York, Coleman, and Luxaire equipment, this cable ensures the reliable transmission of electrical current from the ignition source to the burner assembly. Its robust construction features high-temperature silicone insulation and optimized electrical resistance, effectively preventing voltage leaks and ensuring a consistent arc for efficient fuel-air mixture combustion in demanding HVAC industrial applications.

For service technicians, maintaining the integrity of the furnace ignition wire is paramount to preventing intermittent flame loss or ignition failure. This HVAC ignition lead is built to withstand the intense thermal cycling found within the combustion chamber, providing a stable path for the spark even under harsh environmental conditions. When troubleshooting York ignition system components, replacing a weathered or cracked cable with this genuine Source 1 part restores factory-spec performance and helps maintain the operational efficiency of the entire heating circuit.

• Precise Spark Delivery: Low-resistance core ensures maximum energy transfer for rapid and consistent burner ignition.
• Thermal Resiliency: Advanced high-temperature insulation prevents jacket degradation near hot heat exchangers.
• Multi-Brand Compatibility: Engineered for seamless integration with York, Coleman, and Luxaire gas furnaces and packaged units.
• Enhanced Safety: Secure terminal connections reduce the risk of electrical arcing outside the combustion area.

• How do I know if my ignition cable needs replacement? Look for signs of carbon tracking, brittle insulation, or visible cracks. If the furnace is clicking but failing to light, a high-voltage leak through the cable is a common culprit.
• Is this cable compatible with non-York systems? While primarily designed for York-family brands including Coleman and Luxaire, always verify the lead length and terminal connectors against your specific model requirements.
• Can I use a universal spark plug wire instead? It is not recommended. HVAC-specific cables like the S1-025-21706-702 are rated for the unique environmental and electrical loads of furnace combustion systems.
