Lennox 12U70 Motor
The Lennox 12U70 Motor is a high-efficiency ECM Condenser Fan Motor specifically engineered for residential and light commercial outdoor units. Operating at 208-230V and delivering 1/3 HP, this variable speed motor (300-1200 RPM) optimizes airflow by adjusting its output to meet real-time system demands. As a genuine OEM replacement part, it is frequently used in high-performance Lennox XC20 and XP20 series units. The CCWLE rotation and stud-mount design ensure a precise fit for vertical discharge applications. Built with ball bearings and a 48-frame cast-iron housing, this motor is designed to handle continuous-duty cycles in harsh outdoor environments. By replacing a failing unit with the Lennox 103687-02, technicians can assist in restoring system SEER ratings and ensuring quiet operation. This motor features a 1/2-inch diameter shaft with a 2.17-inch length, facilitating direct-drive compatibility with standard condenser fan blades.
Key Benefits
- Precision Speed Control: The variable speed ECM technology adjusts between 300 and 1200 RPM to maintain optimal head pressure and energy efficiency.
- OEM Compatibility: A direct drop-in for Lennox 103687-02, ensuring electrical and mechanical alignment without field modifications.
- Rugged Construction: Features a cast-iron frame and ball bearings for reliable performance during peak summer thermal loads.
- Quiet Operation: Designed to minimize vibration and acoustic output compared to standard PSC alternatives.
Common Questions
Is the 12U70 motor compatible with non-Lennox brands?
While primarily a Lennox replacement part, it is also used in select Armstrong, Ducane, and Concord equipment. Always verify the Genteq 5SME39HLHF069 manufacturer number for cross-referencing.
Does this motor require a separate run capacitor?
No, as an ECM (Electronically Commutated Motor), the 12U70 features internal electronic protection and control logic, eliminating the need for a traditional external capacitor.
Which direction does the shaft rotate?
The motor is rated for CCWLE (Counter-Clockwise Lead End) rotation. Technicians should verify fan blade pitch before installation to ensure proper airflow direction.
