Lennox 73W02 Blower Motor

The Lennox 73W02 Blower Motor is a high-performance 3/4 HP ECM 3.0 motor engineered for precise airflow control in residential and light commercial HVAC systems. This OEM Lennox replacement part operates as a variable speed blower motor, delivering 1050 RPM to ensure consistent static pressure management and optimal indoor air quality. Designed for 120/240V single-phase applications, this direct drive motor fits frame size 48 and is often utilized as a reliable alternative to legacy part number 606007-02. Please note that this unit is provided without the control module and requires a factory-programmed 84W86 module for full operation. By utilizing ECM technology over traditional PSC motors, the Lennox 73W02 significantly reduces energy consumption and thermal stress, making it the industry standard for technicians performing high-efficiency furnace repairs.

Key Benefits

• Efficient Airflow: 3/4 HP rating provides the necessary torque for balanced air distribution across varying ductwork configurations.
• ECM 3.0 Technology: Higher electrical efficiency compared to standard motors, reducing operational costs and internal heat buildup.
• OEM Compatibility: Genuine Lennox 73W02 ensures exact physical fit and electrical integration, eliminating the need for complex mounting modifications.
• Quiet Operation: Variable speed capabilities allow for ramping up and down, minimizing the "thump" associated with single-speed motor cycles.

Common Questions

Is the control module included with this motor?
No, the Lennox 73W02 is the motor only. You must use your existing compatible module or purchase the specific 84W86 replacement module separately.

Can I use this to replace a PSC motor?
This is an ECM motor designed for specialized control boards. It is not a direct "drop-in" for standard PSC motors without significant system modification.

What causes these motors to fail prematurely?
The most common causes are excessive static pressure from dirty filters, moisture infiltration, or voltage surges. We recommend installing an inline surge protector to safeguard the electronic components.
