Armstrong Furnace R100676-01 Inducer Motor Assy

The Armstrong Furnace R100676-01 Inducer Motor Assy is a high-performance 115V draft inducer engineered for Allied Air families, including AirEase, Concord, Ducane, and Lennox. This 1/20 HP replacement motor operates at 3000 RPM (0.57 Amps) and is critical for maintaining the correct static pressure within the heat exchanger. As a CWLE rotation assembly, it ensures the efficient expulsion of combustion byproducts before the ignition sequence begins. Designed for two-stage furnaces, the R100676-01 package includes the pre-installed motor and housing, often replacing legacy Windjammer styles or older part numbers like 45889-001 and 702110957. When troubleshooting draft inducer failure, technicians should verify 120V at the leads during a call for heat and inspect for common mechanical issues such as seized bearings or cracked housings that compromise the pressure switch circuit.

• OEM Compatibility: Exact fit for Allied Air R100676-01 and cross-referenced Lennox 100676-01 specifications.
• Efficient Venting: High-speed 3000 RPM output maintains the necessary draft for reliable pressure switch closure.
• Integrated Assembly: Includes the Fasco motor, blower wheel, and housing to reduce bench time and simplify installation.
• System Longevity: Helps prevent heat exchanger soot buildup by ensuring a clean purge cycle before the burners fire.

• How do I confirm if my R100676-01 is failing? If you hear a loud grinding noise or if your furnace stays in a lockout because the pressure switch won't close, the inducer is likely dragging or failed.
• Does this replace the older Allied Air 43206001? Yes, this assembly is a direct cross-reference for the 43206 series and 45889 series motors.
• Is any modification required for installation? While dimensionally identical, some older Armstrong installs may require simple plastic barb adapters or electrical lead splicing depending on the original harness configuration.
