Lennox 10U46 Motor Module

The Lennox 10U46 Motor Module is the critical 5.0 ECM control module kit required to restore functionality to high-efficiency variable-speed air handlers and furnaces. As a high-performance 1 HP motor module, it serves as the factory-authorized direct replacement for 66K60 and 66K6001 models. Engineered by Genteq for Lennox HVAC equipment, this module regulates rotation and torque to maintain precise airflow, directly impacting SEER ratings and indoor comfort levels.

Designed for professional installation, the 10U46 module features a 5.65-inch diameter and multi-voltage compatibility (operating on 120/240V single-phase systems). This kit includes the necessary spacer ring and mounting hardware to ensure a secure fit against the motor shell. When diagnosing blower failures, technicians should verify the 3-pin internal motor winding resistance and ensure the blower wheel is balanced before installing the new ECM control module to prevent premature failure of the sensitive electronics.

Key Benefits:

• Direct OEM Match: Ensures full communication with the system board, replacing discontinued 66K60 and 611297-18 units.
• Variable Speed Precision: Utilizes ECM 5.0 technology to modulate 1 HP motors for optimized energy consumption and dehumidification.
• Complete Replacement Kit: Includes the motor module, adapter ring, and specialized mounting screws for a drop-in installation.
• System Compatibility: Validated for use in Lennox CBX32MV and CB31MV series air handlers.
• Enhanced Airflow Control: Restores factory-programmed sequences for heating, cooling, and continuous fan modes.

Common Questions:

Is the 10U46 compatible with my motor?
The 10U46 is specifically factory-programmed for 1 HP Genteq ECM motors used in Lennox-brand air handlers. It is effectively a direct update for the legacy 66K60 series. Always cross-reference the assembly number on your existing module before ordering.

Do I need to replace the entire motor or just the module?
If your motor windings passed a resistance check (typically >100k ohms to ground) and the shaft spins freely without bearing noise, replacing just the 10U46 motor module is the standard solution for electronic control failures.

What is included in the 10U46 kit?
This kit contains the programmed module, a spacer/adapter ring, and multiple lengths of mounting screws to accommodate different motor housing depths.
