Lennox 50J07 Inducer Assembly

The Lennox 50J07 Inducer Assembly is a high-performance 115v 3200rpm Inducer Assy engineered specifically for G23 series furnaces. This OEM Lennox furnace part, manufactured by Fasco (Model 7121-8774 / Type U21B), serves as a critical draft inducer blower that manages combustion airflow and exhaust removal. Operating at a precise 3200 RPM with a 1.50 Amp draw, this centrifugal blower ensures the pressure switch closes reliably to initiate the heating cycle. Designed for direct replacement of legacy components like the LB-65734F, this assembly features a thermally protected motor and air-over cooling to maintain structural integrity during high-static operation. For contractors performing a furnace draft inducer replacement, this kit includes the necessary mounting hardware and the 50J77 gasket to ensure a zero-leak seal against the heat exchanger collector box.

• Optimized Combustion: Heavy-duty 3200 RPM motor provides the consistent static pressure required for safe flue gas venting.
• OEM Reliability: Genuine Lennox replacement part ensures electrical parameters match factory specifications for 115V systems.
• Complete Installation Kit: Includes the essential gasket and mounting screws to prevent common vibration and noise issues.

Common Questions

Is this the correct replacement for a noisy Lennox blower?
Yes, if your current unit shows bearing wear or significant vibration, the Lennox 50J07 is the direct spec-matched draft inducer motor for G23Q5 and G23Q6 series models.

Does this assembly include the discharge gasket?
This package includes the 50J77 gasket, which is vital for maintaining a proper seal between the inducer housing and the furnace transition.

Will this work with 230V systems?
No, this is a 115V inducer assembly. Always verify the voltage on your existing motor nameplate before ordering to prevent board failure.
