Lennox 43W85 Blower Assembly
The Lennox 43W85 Blower Assembly (LB-94724M) is a critical OEM replacement combustion air blower designed for precision exhaust management in high-efficiency gas furnaces. Engineered for the Lennox G60UH series and various residential HVAC units, this 1/30 HP draft inducer operates at 3000 RPM to facilitate the safe removal of flue gases while drawing in fresh combustion air. Featuring a shaded pole motor rated at 115V and 2 amps, this assembly ensures the static pressure requirements for proper burner ignition and sustained thermal efficiency are met without compromising system stability.
Built for direct integration into Lennox furnace blower compartments, the 43W85 includes the specialized housing and fan blade configuration necessary to maintain specific airflow velocity. This HVAC inducer motor uses a CWLE rotation (Clockwise Lead End) to provide consistent venting performance, mitigating the risks of pressure switch trips or incomplete combustion. For technicians performing furnace repair or preventive maintenance, utilizing this genuine combustion blower assembly guarantees dimensional compatibility and electrical alignment with factory specifications, preventing the premature mechanical wear often associated with aftermarket alternatives.
Key Benefits- Optimized Combustion Efficiency: Maintains the exact 3000 RPM required to ensure a stoichiometric air-to-fuel ratio for clean burner operation.
- Direct OEM Compatibility: Specifically engineered as a drop-in replacement for Lennox 43W85 and LB-94724M models, reducing field modification time.
- Industrial-Grade Construction: Features a robust shaded pole motor and high-performance housing designed to withstand elevated flue gas temperatures.
- Precise Electrical Specs: Draws a steady 2.0 Amps at 115V/60Hz, preventing unnecessary load on the integrated furnace control board.
Is this blower compatible with all Lennox G60 series furnaces?
The Lennox 43W85 is the standard replacement for most G60UH-36B and G60UH-48B models. Always verify the part number on the existing data plate to ensure an exact match before installation.
Does this assembly include the necessary gaskets?
This combustion air blower typically ships as a complete assembly containing the motor and housing. For high-temperature seal integrity, we recommend verifying if a new mounting gasket is required for your specific flue transition.
What are the symptoms of a failing 43W85 inducer?
Common indicators include high-pitched bearing noise, vibration during the pre-purge cycle, or the furnace failing to ignite due to the pressure switch not closing from insufficient draft.
