York S1-4101500 Wiring Harness

The York S1-4101500 Wiring Harness is a precision-engineered OEM wiring harness designed for seamless integration within York, Coleman, and Luxaire gas furnaces and air handlers. For technicians tasked with restoring system communication, this HVAC electrical assembly provides a direct-fit solution that eliminates the reliability risks associated with field-spliced repairs. This furnace wire harness replacement features high-temperature rated insulation and precision-terminated connectors that match the original factory pin-out layout. Utilizing a genuine York S1-4101500 ensures that safety circuit signals and control board power remain consistent, preventing the nuisance trips and high-resistance faults often triggered by degraded or rodent-damaged wiring. As a critical York HVAC repair part, this harness maintains the electrical impedance and current-carrying capacity required for modern high-efficiency equipment. Replacing a brittle or scorched harness with this factory-authorized assembly restores original equipment performance and ensures that all integrated furnace control (IFC) logic functions operate according to the manufacturer’s engineered specifications.

Key Benefits

• Ensures exact OEM wiring harness compatibility for point-to-point electrical continuity.
• Constructed with industrial-grade insulation to withstand high-heat vestibule environments.
• Plug-and-play connectors reduce installation time and prevent wiring errors in the field.
• Eliminates voltage drops and signal noise in critical safety limit and sensor circuits.
• Restores factory-standard circuit protection and signal integrity across the HVAC electrical assembly.

Common Questions

How do I verify if the York S1-4101500 is compatible with my specific furnace?

Compatibility is determined by the unit's model and serial number. You should cross-reference this part number with the technical guide or parts list provided by the manufacturer for your specific heating or cooling unit.

Can I use this harness to fix intermittent flame sensor issues?

Yes, if the issue is rooted in a compromised signal path or high resistance in the wiring. Replacing a worn or corroded furnace wire harness is often the final step in resolving stubborn communication errors between the sensor and the control board.

Does this harness require specialized tools for installation?

No specialized crimping tools are usually required, as the York S1-4101500 comes with pre-terminated connectors. However, standard HVAC hand tools are necessary to navigate the cabinet and secure the harness to the existing mounting clips.
