Trane BLW0879 Inducer Assembly

The Trane BLW0879 Inducer Assembly is a high-performance 3-Phase variable draft inducer engineered for precise combustion control in residential and commercial Trane systems. This assembly, encompassing the furnace blower and motor, operates between 33-110V at 60Hz, reaching speeds up to 4700 RPM. As a critical exhaust vent motor, it ensures the safe removal of combustion gases and maintains proper static pressure for system ignition. Designed for direct replacement of legacy components like the D342097P01, this unit integrates seamlessly into HVAC units such as the XR80 and XR90 series. The BLW00879 blower motor features a durable metal housing and thermally protected 3-phase motor, delivering consistent torque and 1/70 HP. For technicians, installing this OEM draft inducer restores factory-spec airflow and combustion efficiency, preventing pressure switch faults and ensuring reliable performance in demanding heating applications.

Key Benefits:

• OEM Compatibility: Precision-fit Trane BLW0879 motor serves as a direct drop-in for BLW00879 and D342097P01, eliminating field modifications.
• Enhanced Efficiency: Variable draft design adjusts RPM to match heating demand, optimizing fuel-to-air ratios and reducing energy consumption.
• Robust Construction: Features a high-grade 3-phase motor with sealed ball bearings and thermal protection for continuous operation in high-temp environments.
• Safety Assurance: Reliably vents flue gases and establishes necessary draft pressure to prevent furnace lockouts and carbon monoxide risks.

Common Questions:

Is the BLW0879 a direct replacement for the BLW00879?
Yes, the BLW0879 inducer assembly is effectively the same component as the BLW00879; the latter is simply the updated manufacturer part number. They share identical mounting patterns and electrical specifications.

What are the signs that my inducer assembly needs replacement?
Frequent pressure switch trip codes, grinding or screeching noises during the pre-purge cycle, or a failure of the furnace to initiate the ignition sequence often point to a failing draft inducer blower.

Can I replace just the motor or must I buy the whole assembly?
For this specific 3-phase inducer, it is recommended to replace the entire assembly (including the blower housing and wheel) to ensure a sealed system and proper balance, preventing premature bearing failure.
