Rotom Motor FB-RFB401 Flue Blower
The Rotom Motor FB-RFB401 Flue Blower is a critical draft inducer assembly engineered for high-efficiency exhaust gas removal in residential and commercial furnaces. This 1/60HP, 120V centrifugal blower operates at a fixed 2800 RPM, ensuring the necessary static pressure to purge combustion byproducts through the heat exchanger before ignition. Built with a durable shaded pole C-frame motor and ball bearings, this unit is a primary Lennox 88K8401 replacement and is cross-compatible with several Fasco A164 and Jakel J238 models. The clockwise rotation (determined from the shaft end) and compact 3.3-inch motor diameter allow for precise fitment in tight cabinets. For technicians troubleshooting furnace short cycling or inducer motor noise, this assembly provides a direct-drop solution to restore system pressure-switch closure and safe flue ventilation.
Key Benefits for Contractors- Direct OEM Cross-Reference: Compatible with a wide range of part numbers including Lennox 85L49, Armstrong 10K5301, and Rotom FB-RFB840.
- Enhanced Durability: Equipped with sealed ball bearings rather than sleeve bearings to prevent premature seizing in high-heat flue environments.
- High-Torque Performance: The 1.3 Amp motor delivers consistent 2800 RPM speeds, maintaining the precise airflow required to prevent limit switch tripping.
- Simplified Installation: Features a standard C-frame mount and 115/120V leads for fast field replacement during emergency no-heat calls.
Is this a compatible replacement for my existing Fasco or Jakel unit?
Yes, the FB-RFB401 is a verified aftermarket replacement for Fasco 7021-9640, 7021-9455, and Jakel J238-087-8171. Always verify the 1/60HP rating and CW rotation before installation.
What are the signs that my current flue blower has failed?
Common indicators include a high-pitched squealing from dry bearings, a humming sound with no fan movement (indicating a seized motor), or the furnace control board throwing a pressure switch error code.
Does this assembly include the gasket?
This specific SKU generally does not include a mounting gasket. It is recommended to inspect the existing seal and apply high-temp RTV or a new gasket during the swap to prevent flue gas leaks.
