Lennox 12F49 Fan Motor

The Lennox 12F49 is a high-performance 1/10 HP condenser fan motor engineered for reliable heat dissipation in residential and light commercial HVAC systems. Operating at 208/230V and a nominal 1075 RPM, this permanent split capacitor (PSC) motor ensures consistent airflow across the outdoor coil to maintain optimal head pressures. As an OEM replacement motor, it is the direct drop-in for the discontinued Lennox 97M50, utilizing a standard 48-frame diameter and shaft specifications suited for Lennox air conditioners and heat pump units. For service technicians, this motor simplifies field installs by matching original electrical leads and mounting configurations, reducing labor time during emergency service calls. The single-phase design is built to withstand high ambient temperatures, ensuring the condensing unit remains operational during peak cooling loads without thermal tripping.

Key Benefits for HVAC Professionals

• Direct OEM Compatibility: Engineered specifically to replace the Lennox 97M50 without requiring bracket modifications or shaft adjustments.
• Optimized Heat Exchange: The 1075 RPM rating is calibrated to match original fan blade pitch for maximum CFM output.
• Broad Application: Suitable for a wide range of Lennox HP26, HP29, and HS26 series units utilizing 1/10 HP specifications.
• Durable Construction: Built with high-grade insulation and bearings to handle the cycling demands of HVAC outdoor fan motors.

Common Installation and Compatibility Questions

What capacitor is required for the Lennox 12F49?
This motor typically requires a 5 MFD / 370V run capacitor. Always check the nameplate on the new motor to verify the correct capacitance before wiring.

Can this motor replace a higher horsepower fan motor?
No, a 1/10 HP motor should only replace motors of the same or lower horsepower. Using this to replace a 1/4 HP or 1/3 HP motor will result in premature winding failure.

Is the rotation reversible on this Lennox motor?
The 12F49 is designed with a specific factory rotation (typically CCWLE). Verify the rotation of your existing blade to ensure proper airflow direction before finalizing the install.
