York S1-373-25771-000 Power Harness

The York S1-373-25771-000 Power Harness is a critical 4-pin OEM replacement designed to restore reliable voltage communication between HVAC control boards and system components such as blower motors and limit switches. This high-spec wiring harness is engineered for high-temperature environments, featuring PVC-insulated wiring rated up to 1000V and 90°C. As a direct successor to the S1-37315424001 electrical heat harness, it ensures seamless integration without the need for field modifications or custom splicing.

For service technicians addressing intermittent unit failures or brittle conductor leads, the York S1-373-25771-000 provides a factory-molded terminal connection that minimizes resistance and prevents voltage drop. This harness repair kit is essential for maintaining the operational safety and duty cycle of York air handlers and electric furnaces. Utilizing genuine York HVAC parts ensures that the system meets original factory amperage draws and signal timing requirements, effectively preventing premature board failure or motor stalls.

• Factory-Spec 4-Pin Connector: Provides a secure, vibration-resistant interface for air handler control boards and fan motors.
• High-Temperature Rating: PVC insulation rated for 90°C (194°F) to withstand the ambient heat of electric heating coils.
• 1000V Dielectric Strength: Robust electrical separation prevents arcing and interference in high-voltage HVAC compartments.
• Precision Lead Length: Engineered for specific York cabinet layouts to ensure clean wire routing and prevent interference with moving parts.
• Direct Replacement: Fully compatible with legacy part number S1-37315424001 for rapid field restoration.

Is the S1-373-25771-000 compatible with non-York air handlers?
