Lennox 72W41 Motor

The Lennox 72W41 is a high-performance 1/2 HP 120/240V ECM blower motor specifically designed for Lennox HVAC systems. As a critical component in variable-speed air handlers and furnaces, this motor operates at a nominal 1250 RPM and provides precise airflow modulation to maintain consistent static pressure. Its dual-voltage capability (120/240V) and 50/60Hz compatibility make it a versatile direct OEM replacement motor for contractors servicing SLP98, SL280, and CBX series units. Engineered with a durable 48Y frame and a 1/2-inch flat shaft, the Lennox 103070-01 ensures seamless integration with existing blower wheel assemblies.

For technicians performing a Lennox blower motor replacement, verifying the control module's integrity is essential, as this unit is typically sold as the motor only. Utilizing variable-speed HVAC motor technology helps reduce noise levels and optimizes energy consumption by adjusting to the system's real-time demand. This genuine Lennox 72W41 motor is built for air-over continuous cooling and features Class B insulation to withstand high-demand heating and cooling cycles without compromising performance.

• Precise Airflow Control: Variable-speed technology maintains indoor comfort by eliminating the harsh starts and stops associated with single-speed motors.
• OEM Compatibility: Designed for an exact fit in Lennox CBX25UHV, CBX32MV, and SLP98 units, ensuring no modifications are needed to the mounting brackets.
• Enhanced Efficiency: Reduces electrical consumption by matching torque and RPM to the specific ductwork requirements.
• Robust Construction: Features a 4.5-inch single-side flat shaft and a rugged 48Y frame for long-term reliability in vertical or horizontal airflow configurations.

Does the Lennox 72W41 include the motor control module?
No, this part number represents the ECM motor without the module. If the module has failed, you must order the compatible Lennox module kit separately or reuse the existing one if it tests within functional parameters.

Can this motor be used as a replacement for the 103070-01?
Yes, the 72W41 is the direct replacement for the legacy part number 103070-01. Always verify the shaft diameter and frame size against the original unit before installation.

What units are compatible with the 72W41 blower motor?
This motor is commonly found in high-efficiency Lennox air handlers and gas furnaces, including the CBX and SLP series. Check your unit’s data plate to confirm the 1/2 HP rating and voltage requirements.
