Armstrong Furnace R47471-002 Blower Motor

The Armstrong Furnace R47471-002 Blower Motor is a high-performance 1/3 HP replacement motor designed specifically for compatible Armstrong, Allied, and Ducane furnace and air handler assemblies. Operating at 208-230V with a 2.2 Amp draw, this single-phase 48Y frame motor provides consistent, multi-speed airflow to maintain static pressure and system equilibrium. With a rated speed of 1120 RPM and a 3-speed configuration, it allows for precise CFM adjustments to meet specific heating and cooling load requirements. This OEM blower motor features a 1/2-inch diameter by 2.5-inch length double-side flat shaft, ensuring a secure fit with the blower wheel. For a successful swap, ensure you use a new 7.5 MFD @ 370VAC capacitor and verify that the rotation matches the clockwise lead end (CWLE) orientation of your existing blower housing. Built for air-over continuous cooling, this motor is thermally protected to prevent winding failure during high-demand cycles.

• Direct OEM Compatibility: Engineered as a drop-in replacement for part numbers R47471-001 and R45846-001, reducing installation time for technicians.
• Multi-Speed Flexibility: Features a 3-speed design to optimize airflow for varied seasonal requirements in Armstrong HVAC systems.
• Industrial-Grade Build: Utilizing a 48Y frame and self-aligning ball bearings, this motor is designed for longevity in residential and light commercial applications.
• Thermal Protection: Integrated internal protection helps prevent overheating and extends the service life of the motor windings.

Is this a universal motor or a direct OEM replacement?
This is a direct OEM replacement motor for Armstrong Air and Allied units. While some universal motors may fit the 48Y frame, using this specific R47471-002 ensures the correct wiring harness and lead lengths for a plug-and-play installation.

Does this motor include a new capacitor?
No, the capacitor is sold separately. This motor requires a 7.5 MFD / 370V run capacitor. We recommend replacing the capacitor whenever a furnace blower motor replacement is performed to ensure the new motor starts under the correct electrical load.

What direction does this motor rotate?
The R47471-002 is designed for Clockwise Rotation (CWLE) when viewed from the lead end. Always confirm the rotation of your existing blower wheel before completing the installation.
