Lennox 73W03 Motor Only
The Lennox 73W03 is a high-performance 1 HP 3.0 ECM motor designed as a direct OEM replacement motor for compatible Lennox HVAC systems, inducer assemblies, and air handlers. Engineered for precision and efficiency, this 1050 RPM blower motor utilizes advanced ECM technology to maintain consistent airflow while reducing total energy consumption compared to traditional PSC motors. Operating on a 120/240V single-phase circuit, it features a standard 48 frame size and is built for horizontal mounting using a belly-band bracket. This furnace blower motor includes an integrated microchip that optimizes torque and speed, ensuring quiet and reliable operation under varying static pressure conditions.
For technicians in the field, it is important to note that the Lennox 73W03 is the motor only and does not include the control module. It is common practice to inspect the existing module and blower wheel for imbalance or electrical damage before installation, as these are frequent causes of premature blower motor failure. This genuine Genteq style motor is built to the exact technical specifications required for Allied, Armstrong, and Concord equipment, providing a seamless fit and restored performance for high-efficiency heating and cooling units.
Key Benefits- Energy-Efficient ECM Technology: Significant reduction in energy draws compared to standard induction motors.
- Variable Speed Compatible: Supports modulated airflow for better humidity control and temperature consistency.
- Direct OEM Fit: Ensures proper electrical 3-pin connection and mounting alignment without field modifications.
- Robust Build Quality: Features high-grade bearings and windings engineered for continuous duty in residential and light commercial applications.
Is the control module included with the 73W03?
No, this is the motor only. You must reuse your existing programmed module or purchase a compatible Lennox module separately.
Does this motor replace older 2.0 or 2.3 ECM versions?
This is a 3.0 series motor. While it is physically similar, always verify compatibility with your specific control module as programming varies between versions.
What causes these motors to fail prematurely?
The most common causes are moisture ingress, power surges, or high static pressure caused by dirty filters or undersized ductwork.
