Lennox 69M33 Inducer Assembly

The Lennox 69M33 Inducer Assembly is a high-performance OEM furnace replacement part designed for precision combustion air delivery in residential and commercial heating cycles. Operating at 208-230V with a consistent 3200 RPM, this centrifugal blower ensures optimal manifold pressure and safe venting of flue gases. This unit is built as a direct 1-to-1 match for part number 69M3301, featuring a robust 1/12 HP PSC motor that effectively eliminates common pressure switch trip errors caused by failing bearings or decreased torque in older assemblies.

As an essential furnace draft inducer, the 69M33 provides a 3250 RPM peak capacity to maintain the specific air-to-fuel ratio required by Lennox HVAC systems. The 1-phase motor is thermally protected and utilizes a 3 MFD capacitor to handle the high-static startup requirements of high-efficiency furnaces. Contractors rely on this assembly for its seamless physical fit and electrical compatibility with multiple Lennox furnace models, ensuring reduced labor time and reliable ignition staging during cold-start sequences.

• Maximum Performance: Delivers 3200 RPM at 208-230V to maintain precise draft pressure for efficient combustion.
• OEM Compatibility: Fully interchangeable with Lennox 69M3301, ensuring a perfect bolt-on installation without cabinet modifications.
• Industrial Build: Features a 1/12 HP motor designed for high-cycle environments and reliable air-over cooling.
• Optimized Efficiency: Permanent Split Capacitor (PSC) design reduces amperage draw while providing consistent torque.

Common Questions

Is the 69M33 compatible with the 69M3301 model?
Yes, these parts are technically identical and serve as direct replacements for one another in all documented Lennox applications.

What are the signs that this inducer assembly needs to be replaced?
Common indicators include loud grinding noises from the bearings, a "failed to ignite" code on the furnace control board, or a pressure switch that fails to close during the pre-purge cycle.

Does this unit include the cooling fan and housing?
The assembly comes as a complete combustion blower unit, including the motor and the necessary housing for immediate integration into the flue system.
