York S1-7990-6451 Inducer Assembly

The York S1-7990-6451 Inducer Assembly is a high-performance draft motor designed for direct replacement in specific York, Coleman, and Luxaire gas-fired furnaces. This 120V, single-stage centrifugal blower operates at 2950 RPM, ensuring positive pressure is maintained to exhaust combustion gases through the flue pipe effectively. Engineered to meet OEM specifications, this assembly features a robust motor housing and a precision-balanced impeller to minimize vibration and bearing wear. As a critical component for the furnace ignition sequence, the S1-7990-6451 integrates a pre-installed gasket to ensure a combustion-tight seal against the collector box. This unit is the authorized 7102-2187 replacement inducer, resolving common pressure switch trip errors and motor seizure issues found in aging systems. Field technicians will find the bolt-on installation straightforward, maintaining system static pressure and ensuring safe, reliable furnace cycles during high-demand heating periods.

• OEM Compatibility: Exact drop-in replacement for the 7102-2187 York inducer motor, eliminating the need for mounting modifications or bracket adjustments.
• High-Speed Extraction: The 2950 RPM motor provides the necessary cubic feet per minute (CFM) to clear the heat exchanger of combustion byproducts.
• Gasket Included: Comes equipped with a high-temperature gasket to prevent carbon monoxide leaks and ensure proper furnace draft inducer pressure.
• Quiet Operation: Precision-engineered components reduce decibel levels during the startup and run cycles, preventing common customer complaints regarding "whining" or "grinding" noises.

Does the S1-7990-6451 include the cooling fan blade?
Yes, this is a complete assembly including the motor, internal impeller, and the external cooling fan to prevent motor overheating.

Will this resolve a "pressure switch stuck open" error code?
If your diagnostic shows the existing motor is not reaching the required RPM or has a failed bearing, installing this York furnace replacement part will restore the proper pressure differential required to close the switch.

Is this a 115V or 230V component?
This is a standard 120Vac unit, designed for seamless integration with the existing furnace control board and wiring harness.
