York S1-025-31810-001 Harness Assembly

The York S1-025-31810-001 Harness Assembly is a factory-authorized OEM HVAC replacement part engineered for high-precision electrical signal and power distribution within residential and light commercial equipment. This 6-pin wire harness is a critical interface for the system’s control logic, facilitating communication between the HVAC control board and major mechanical components like the compressor, condenser fan, or blower motor. Designed to withstand the thermal stressors and mechanical vibrations common in high-performance refrigeration cycles, this assembly ensures consistent continuity and prevents signal dropouts that can lead to diagnostic fault codes or intermittent system failure.

For service technicians, the York S1-025-31810-001 offers a direct drop-in solution for legacy harness failures caused by corrosion, terminal pitting, or insulation compromise. While primarily compatible with York D1NA024N05606C series units, its standardized pin configuration maintains the high-voltage and low-voltage separation required for modern safety protocols. Utilizing genuine York service parts for terminal repairs preserves original equipment specifications and prevents the impedance issues often associated with generic aftermarket pigtails or spliced connections.

Key Benefits:

• Ensures reliable HVAC electrical connectivity between control boards and system peripherals.
• Features a 6-pin terminal interface for secure, plug-and-play installation in compatible York package units.
• Constructed with high-temp insulation to resist environmental degradation in outdoor condenser compartments.
• Maintains factory wiring diagram integrity, simplifying future troubleshooting and field diagnostics.
• Direct cross-reference for York part number 025-31810-001 and related Source 1 inventory.

Common Questions:

Is this harness compatible with multiple York models?
Yes, while frequently cited for the D1NA series, this replacement harness assembly fits various York, Coleman, and Luxaire systems that utilize the same 6-pin control board connector architecture.

Does this assembly include the plastic connector housing?
Yes, the S1-025-31810-001 comes as a complete assembly featuring pre-terminated leads and the necessary 6-pin connector block for a secure physical lock.

What causes this specific harness to fail?
Most field failures result from moisture intrusion at the terminal pins or vibration-induced wire fatigue near the strain relief point, making a full assembly replacement more reliable than pin-by-pin repairs.
