Lennox 74W55 Blower Assembly
The Lennox 74W55 Combustion Blower Assembly is a high-performance draft inducer specifically designed for modern high-efficiency furnaces. Also referenced under part numbers 74W5501 and LB-94724AA, this assembly is a critical component for maintaining the correct fuel-to-air ratio during the combustion cycle. Operating at 120 Volts and 60 Hz, this 1/40 HP motor delivers 3250 RPM to effectively pull flue gases through the heat exchanger, ensuring safe and efficient exhaust. As an OEM Lennox replacement part, it is frequently used in 80G1UH and other Lennox, Armstrong, and Ducane furnace models. For technicians, the unit’s 1.18 Amp draw and clockwise lead end (CWLE) rotation provide a direct-fit solution that eliminates field modifications. Installing a genuine Lennox draft inducer motor ensures your system meets original factory specifications for static pressure and airflow, preventing premature pressure switch trips and improving overall furnace combustion efficiency.
Key Benefits:- Precision Performance: Built to 1/40 HP and 3250 RPM specifications to ensure reliable draft induction.
- Broad Compatibility: Replaces 74W5501 and Fasco 70581846, fitting Lennox, Armstrong, and Ducane units.
- Technical Reliability: Features a durable 1.18 Amp motor designed for the rigorous start-stop cycles of residential heating.
- Direct Fit: Factory-designed mounting points and electrical leads simplify furnace repair for HVAC contractors.
- Is the 74W55 compatible with the 74W5501? Yes, the Lennox 74W55 is 100% identical and serves as a direct replacement for the 74W5501.
- Does this assembly include the pressure port? Yes, this combustion air blower includes the necessary ports for pressure switch hose connections.
- What causes a draft inducer to fail? Bearings or moisture buildup in the housing are common culprits; replacing with an OEM Lennox motor restores quiet operation and proper venting.
