Lennox 81W45 Blower

Upgrade or repair your Lennox heating system with the Lennox 81W45 combustion air blower assembly. This OEM Lennox replacement part, also identified by model LB-94724AC, is a critical component for maintaining proper draft and air-fuel mixtures in high-efficiency furnaces. It features a high-performance 1/20 HP PSC motor capable of 2800-3200 RPM, operating on a standard 115V single-phase circuit. This assembly is a direct replacement for Lennox draft inducer motors in specific furnace series, including the popular EL296UH and EL196UH models. With a low current draw of 0.3-0.6 Amps, this centrifugal blower ensures energy-efficient operation while providing the necessary static pressure for the heat exchanger. The rugged housing and precision-balanced blower wheel are engineered to withstand high temperatures and dampen vibration, ensuring long-term reliability in demanding residential and light commercial environments. Verify your inducer assembly part number to ensure a seamless drop-in fit during your next service call.

• Direct OEM Compatibility: Engineered specifically for Lennox EL296 and EL196 series units to ensure exact mounting and electrical matches.
• Precision Airflow: The 1/20 HP motor maintains a steady 2800-3200 RPM range, securing the draft needed for complete combustion.
• Optimized Efficiency: Permanent Split Capacitor (PSC) design offers reliable torque and lower power consumption (max 0.6A) compared to generic alternatives.
• Durable Construction: Built to withstand the corrosive environment of flue gases and high-thermal cycles.
• Standard Electrical Specs: Operates on 115V, 60Hz power with a standard 1-phase configuration for easy field wiring.

• Does this include the blower wheel and housing? Yes, the 81W45 is a complete Combustion Air S/A (Sub-Assembly) including the motor, housing, and blower wheel for a full replacement.
• What are the symptoms of a failing inducer motor? Common signs include loud screeching or humming noises, a "pressure switch stuck open" error code on the control board, or the furnace failing to ignite after the initial startup sequence.
• Can I use this for non-Lennox brands? This assembly is specifically designed for Lennox-built equipment; always check your original equipment manufacturer (OEM) part number before attempting to cross-reference.
