York S1-373-23884-001 Control Kit

The York S1-373-23884-001 Ignition Control Kit is a critical OEM replacement component designed for precision furnace sequencing and burner management. This kit serves as the factory-authorized direct replacement for York 2940-3251, ensuring a seamless drop-in installation without the need for field modifications or wiring harness adaptations. Engineered for high-efficiency gas-fired systems, this integrated furnace control board manages the induction motor, pressure switch monitoring, ignition cycles, and flame rectification. It maintains specific hot surface ignition (HSI) timing and micro-ammeter flame sensing tolerances to prevent nuisance lockouts and delayed ignition. For HVAC contractors, using this genuine York furnace part guarantees the restoration of the unit’s original safety parameters and operational efficiency. The robust circuitry is designed to handle voltage fluctuations and harsh mechanical room environments, providing reliable direct spark ignition and single-stage gas valve control for consistent residential heating performance.

• Direct OEM Compatibility: Replaces legacy part number 2940-3251 with exact mounting footprints and terminal locations.
• Advanced System Diagnostics: Integrated logic allows for rapid troubleshooting of airflow, ignition, and flame signal errors.
• Enhanced Safety Logic: Maintains strict timings for pre-purge, inter-purge, and post-purge cycles to ensure safe combustion.
• Industrial Grade Build: Resists thermal cycling stress and electronic noise for long-term reliability in the field.

Is the S1-373-23884-001 compatible with my legacy York furnace?
Yes, this kit is the designated replacement for the 2940-3251 model. If your service manual specifies that number, this control board is the correct technical update.

Does this kit include the necessary wiring harness for older models?
As a direct replacement kit, it is designed to integrate with the existing 12-pin or 9-pin molex connectors standard on York furnace platforms associated with this part series.

What causes typical failure on these control boards?
Most failures result from moisture exposure, carbon tracking on the underside of the PCB, or relay contact pitting due to high-cycle demand and fluctuating input voltage.
