Lennox 89W73 Motor
The Lennox 89W73 Motor is a high-performance direct drive blower motor designed specifically for Lennox, Armstrong, and Ducane air handlers and residential furnaces. Delivering 1/5 HP at a rated speed of 975 RPM, this PSC blower motor provides precise airflow management through its 3-speed architecture. Engineered for 208-240V single-phase electrical systems, the 89W73 (cross-referenced as 104849-01) features a 48-frame diameter and CCWLE (Counter Clockwise Lead End) rotation to ensure seamless drop-in compatibility with existing blower assemblies like the BCS3M and CBA25UH series.
For contractors, this Lennox OEM replacement motor is the standard for restoring factory-spec static pressure and CFM delivery. Technical specs include a 1.1 Amp draw and a 50/60Hz frequency rating, housed in a durable casing built to withstand the rigors of high-cycle residential HVAC duty. When replacing this 89W73 unit, always inspect the run capacitor and blower wheel balance to prevent premature bearing wear or vibration-induced failure. This genuine part ensures the HVAC blower assembly maintains its design efficiency, reducing call-backs and ensuring quiet operation.
Key Benefits:- Precise Multi-Speed Control: Features a 3-speed design to allow for custom airflow tuning based on the specific heating or cooling tap requirements of the system.
- Direct OEM Compatibility: Verified replacement for Lennox part 104849-01 and 66709100, ensuring the mounting holes and shaft dimensions align perfectly with the original 48-frame bracket.
- Optimized Performance: Operates at 975 RPM with a low 1.1 Amp draw, providing an efficient 1/5 HP output that maintains system static pressure without excessive energy consumption.
- Broad System Application: Integrated into multiple Lennox and Allied Air models, including the CBX25UH and CBA25UH air handler lines.
What is the rotation direction for the Lennox 89W73?
This motor is rated for CCWLE (Counter Clockwise Lead End) rotation. Always verify the rotation of the existing fan blade or blower wheel before installation to ensure proper airflow direction.
Can I use this motor in a 120V system?
No, the 89W73 is strictly rated for 208-240V single-phase applications. Attempting to run this motor on 120V will result in failure to start or permanent damage to the windings.
Should I replace the capacitor when installing this motor?
Yes, it is professional best practice to replace the run capacitor whenever a new HVAC blower motor is installed. A weakened capacitor can cause the new motor to overheat or fail to reach its rated 975 RPM.
