Lennox 49L66 Fan Motor

The Lennox 49L66 Fan Motor (identical to 49L6601) is an OEM PSC condenser fan motor engineered for heavy-duty commercial and residential HVAC applications. This 3/4 HP HVAC motor operates at a high-torque 1075 RPM and is rated for 460V (380-460V range), 50/60 Hz, single-phase power. Built with a 48 frame and durable ball bearings, it supports vertical mounting via a belly band configuration. The CCWLE rotation and 1/2 x 4-inch shaft ensure precise compatibility with several Lennox, Allied, Armstrong, and Ducane units, including GCS16 and LCH series. For peak efficiency and to prevent overheating, it is standard practice to pair this motor with a 20 MFD 370 VAC capacitor and verify that the fan blades are balanced during installation.

Key Benefits:

• OEM Compatibility: Precision-fit for Lennox 49L6601, ensuring zero-clearance integration with industrial air handlers and condensers.
• Industrial Build: Features a rugged 48 frame size and ball bearing construction for extended life in continuous-duty cycles.
• High-Voltage Performance: Optimized for 460V 3/4 HP requirements, maintaining consistent 1075 RPM airflow under static pressure.
• Thermal Protection: Equipped with an internal thermal overload protector to safeguard the windings against voltage spikes or excessive heat.
• Versatile Application: Direct replacement for series including GCS16-090, HP29-090, and LCH series rooftop units.

Common Questions:

Is the 49L66 the same as the 49L6601?
