York S1-373-27916-001 Furnace Kit

The York S1-373-27916-001 Furnace Kit is a critical PSC Modulating Furnace Kit designed for veteran technicians maintaining 80% and 95% modulating gas furnaces. This genuine York OEM replacement part provides the necessary hardware to restore precision heating performance by upgrading or repairing existing PSC motor control systems. Unlike standard single-stage components, this field-serviceable kit integrates a modulating gas valve and advanced control logic to regulate thermal output based on real-time demand, significantly reducing energy consumption and noise levels during operation. The kit includes the necessary high-voltage and communication harnesses to ensure a direct-fit interface with compatible York air handlers and furnace chassis. By utilizing a permanent split capacitor (PSC) configuration, the motor maintains a consistent torque profile while adjusting airflow to match the modulated burner firing rate. This ensures the HVAC furnace kit delivers stable discharge temperatures and eliminates the frequent cycling typical of lower-tier atmospheric systems in residential and commercial applications.

• Precise Modulation: Facilitates variable heating output to match the building's thermal load precisely.
• Direct OEM Integration: Engineered for quick drop-in replacement in York 80% and 95% AFUE modulating units.
• Optimized Efficiency: Reduces electrical draw and gas consumption through intelligent demand-based firing.
• System Acoustics: Engineered to minimize operational noise by optimizing blower ramp profiles.
• Technician-Ready: Includes all necessary wiring harnesses and mounting hardware for immediate installation.

Is this kit compatible with ECM motor systems?
No, the S1-373-27916-001 is specifically engineered for PSC (Permanent Split Capacitor) modulating furnaces. For ECM-based systems, verify the specific control board part number required for your chassis.

Does this kit include the modulating gas valve?
Yes, this York S1-373-27916-001 is a comprehensive upgrade/repair kit that typically includes the valve, control board, and necessary jumpers required for a full system synchronization.

Can I use this on a single-stage furnace?
No. This kit is strictly for modulating furnace systems. Using these components on non-modulating equipment will result in control failure and potential safety hazards.
