Lennox 58W01 Blower Assembly

As an HVAC technician, you know that a failed inducer is often the culprit behind a furnace that won't initiate its ignition sequence. The Lennox 58W01 Blower Assembly is the exact OEM replacement required to restore the pressure differential needed to close the circuit on the pressure switch. This induced draft blower assembly is pre-assembled, featuring a 115V 1/30 HP draft motor housed in a durable assembly designed to pull combustion air through the heat exchanger and expel flue gases safely through the venting system.

Running at 3400 RPM with a 1.8 Amp draw, this Fasco-manufactured unit (Model 702111106) is engineered for the high-heat environments of Lennox high-efficiency gas furnaces. It replaces several legacy part numbers, including R45037-001 and 7021-11106, ensuring a drop-in fit without the need for field modifications. When you're dealing with a "no heat" call and a seized inducer, using a genuine Lennox replacement part is the only way to ensure the factory-specified airflow and CFM are maintained for safe operation.

Key Benefits for Contractors

• OEM Precision: Guaranteed 115V compatibility and mounting alignment for Lennox gas furnaces like the CG90 and CG95 series.
• Efficient Combustion: The 1/30 HP motor provides the necessary static pressure to ensure proper venting and prevent nuisance pressure switch trips.
• Sealed Bearings: Features permanently lubricated ball bearings for quiet operation and a longer service life in high-temperature applications.
• Complete Assembly: Includes the motor and blower housing, reducing installation time during emergency service calls.
• Factory-Spec Performance: Delivers a consistent 3400 RPM rotation (CWLE) to meet the original equipment’s flue gas evacuation requirements.

Common Technical Questions

What furnace models is the Lennox 58W01 compatible with?
This inducer assembly fits several popular Lennox units, including the CG90CB, CG92TB, and CG95TB series. Always cross-reference the part number on the existing motor housing or the furnace's data plate.

Does this unit come with the mounting gasket?
The 58W01 typically does not include the 57W95 gasket. It is professional best practice to inspect and replace the inducer gasket during installation to prevent flue gas leakage.

How do I know if the inducer motor or the pressure switch is failing?
Perform a manometer test at the pressure switch port. If the inducer blower is spinning but not pulling sufficient vacuum to meet the switch's set point, check for blockages in the heat exchanger or vent pipe before replacing the assembly.
