Trane BLW0864 Inducer Draft Assembly

The Trane BLW0864 Inducer Draft Assembly is a genuine OEM 1-stage draft inducer motor designed for high-performance venting in residential gas furnaces. As a direct 7021-11543 replacement, this blower motor assembly ensures the critical removal of combustion gases while establishing the precise static pressure required for pressure switch closure. This single-speed component is engineered for 115V, 60Hz operation, pulling approximately 1.75 Amps at a rated 3400 RPM. Built with a shaded pole motor, the unit provides the necessary durability to handle frequent cycling and high-temperature flue gas environments.

Technicians relying on exact mechanical footprints will find the BLW0864 accommodates seamless integration into Trane and American Standard furnaces, eliminating the need for mounting modifications often required with universal aftermarket kits. Using this OEM inducer blower maintains the system's UL certification and original combustion airflow specifications, which is vital for preventing nuisance trips and ensuring efficient heat exchanger performance during the ignition sequence.

• OEM Compatibility: Replaces factory part numbers 7021-11543 and BLW00864 without specialized retrofitting.
• Precise Airflow: Maintains 3400 RPM to meet specific static pressure requirements for consistent burner ignition.
• Robust Construction: Features high-temp housing and specialized bearings to withstand corrosive combustion byproducts.
• Efficient Venting: Optimal blower motor design ensures complete flue gas evacuation, reducing the risk of carbon monoxide backup.

• Will this fix a furnace that is not starting due to a pressure switch error? Yes, if the existing inducer is seized or failing to reach the proper RPM, replacing it with the BLW0864 will typically resolve pressure switch closure issues.
• Is this assembly compatible with both natural gas and propane furnaces? Yes, the inducer assembly is designed to handle combustion air for both fuel types in compatible Trane/American Standard units.
• Does this include the necessary gaskets for installation? While configurations can vary, it is recommended to inspect the mounting gasket during removal; often, a new gasket or high-temp RTV is required for a gastight seal.
