York S1-373-03481-717 Wire
The York S1-373-03481-717 is a specialized 18AWG flame sensor wire engineered to maintain signal integrity within the high-temperature environment of a furnace burner transition. For technicians diagnosing ignition failures or erratic flame signals, this flame sensor lead wire is critical for ensuring the flame rectification circuit functions within the narrow microamp parameters required by the control board. The 18-gauge conductor is wrapped in high-grade insulation designed to resist the thermal stressors common in modern HVAC wire applications, preventing brittle cracking or grounding issues that lead to nuisance system lockouts. This authentic Johnson Controls replacement part provides a direct, low-resistance path from the sensor probe to the integrated furnace control, eliminating the signal noise often introduced by substandard field repairs. When performing a furnace flame sensor connector replacement, using factory-spec leads like the S1-373-03481-717 ensures the burner assembly meets original equipment performance standards for safe and reliable combustion sequencing.
- High-Temperature Insulation: Specifically rated to withstand the ambient heat of burner compartments without melting or degrading signal strength.
- Optimized Conductivity: 18 AWG thickness ensures minimal resistance for the low-voltage microamp signal required for flame detection.
- Direct OEM Fit: Pre-terminated for immediate installation in York, Coleman, and Luxaire gas furnaces, reducing time spent on the job site.
Common Technical Questions
What causes a flame sensor wire to fail? Over time, the high heat inside the cabinet can make the insulation brittle, leading to cracks that allow the signal to short to the chassis. This results in the control board failing to see the flame even if the burner is lit.
Can I splice this wire to extend it? It is not recommended for flame sensing circuits. Splicing introduces resistance and potential points of failure in a circuit that operates on extremely low current. Using the full York S1-373-03481-717 ensures a continuous, reliable connection.
Will this resolve a "no flame' lockout? If your diagnostics show that the sensor probe is clean but the control board is not registering microamps, the lead wire is the likely culprit. Replacing the S1-373-03481-717 restores the communication path to the controller.
