York S1-7990-6501 Booster Assembly

The York S1-7990-6501 Booster Assembly is a critical OEM replacement part designed for high-efficiency gas furnaces within the York, Coleman, and Luxaire families. This BDF Vent Booster Assembly is engineered to facilitate proper flue gas evacuation, ensuring the pressure switch closes to allow the ignition sequence to proceed. As a centrifugal blower, it manages the venting of combustion byproducts safely out of the heat exchanger. When diagnosing a furnace pressure switch error or a failed draft inducer motor, this direct-fit component restores the necessary static pressure for system operation. Constructed with durable materials to withstand high thermal cycling, the S1-7990-6501 eliminates the compatibility issues often found with universal aftermarket alternatives. Installing this vent blower motor ensures that the vent system maintains its integrity and prevents CO accumulation by maintaining precise CFM output and vacuum pressure. Always verify the voltage and lead configurations against the existing harness to ensure a seamless drop-in installation during field service calls.

• Precision Airflow: Engineered to provide the exact static pressure required for York furnace venting requirements.
• Direct OEM Fit: Reduces labor time with a perfect match for mounting brackets and electrical connections.
• Thermal Protection: Internal motor design prevents overheating during continuous duty cycles in high-demand environments.
• Corrosion Resistance: Housing and impeller are built to resist the acidic condensate common in high-efficiency venting.

What are the signs that my S1-7990-6501 needs replacement?
Common indicators include high-pitched bearing noise, an inducer motor that hums but won't turn, or a pressure switch that fails to close, preventing the burners from igniting.

Does this assembly include the necessary gasket?
Standard service practice requires a new gasket or high-temp RTV silicone during installation to ensure an airtight seal between the collector box and the booster housing.

Can I use this for non-York HVAC equipment?
This specific booster assembly is a proprietary Johnson Controls part. While it fits certain Coleman and Luxaire units, cross-referencing the factory part number is necessary for non-York applications.
