Lennox 28G66 Inducer Assembly

The Lennox 28G66 Inducer Assembly is a critical OEM replacement part designed for high-efficiency gas furnaces, specifically the G24 series units. Operating at 230V, this complete draft inducer blower assembly includes the motor and wheel, ensuring proper combustion air throughput and venting of flue gases. This part is functionally identical to the Lennox 28G6601 and serves as a direct drop-in replacement, maintaining the original equipment manufacturer's pressure switch calibrations and airflow dynamics. For technicians performing HVAC furnace repair, installing this 230V inducer motor restores system static pressure and prevents nuisance trips related to pressure switch failures or flue obstructions. Its heavy-duty construction is engineered to withstand high thermal loads, ensuring consistent performance in commercial and residential gas furnace heating applications. Always verify the voltage and lead configurations against the existing draft inducer motor to ensure circuit board compatibility during installation.

• Direct OEM Replacement: Ensures precise fitment and restores original factory-specified combustion air motor performance for Lennox units.
• Integrated Assembly: Includes the pre-balanced wheel and motor, reducing vibration and extending the service life of the furnace draft motor leads.
• Electrical Compatibility: Specifically wound for 230V applications, providing the necessary torque to maintain correct RPMs for venting.
• Cross-Compatibility: Fully interchangeable with part number 28G6601, simplifying inventory and part identification.

Common Installation Questions

When should a Lennox 28G66 be replaced?
Replacement is typically necessary when the furnace inducer assembly exhibits bearings failure (indicated by high-pitched squealing), a cracked housing, or an electrical failure preventing the motor from reaching the necessary RPM to close the pressure switch.

Is the 28G66 interchangeable with 120V models?
No, this is a 230V inducer motor. Installing this in a 120V circuit will cause the motor to fail to start or run at insufficient speeds, while installing a 120V motor in a 230V application will result in immediate motor burnout.

Does this assembly include the gasket?
Technicians should always inspect the mounting gasket during HVAC vent motor replacement. While the 28G66 provides the motor and wheel, reusing an old, compressed gasket can lead to air leaks; utilizing a new high-temp RTV or OEM gasket is recommended for a proper seal.
