Lennox 10B66 Motor Kit
The Lennox 10B66 Motor Kit is a critical OEM replacement solution designed for high-efficiency residential systems requiring a 1/2 HP ECM 5.0 EON blower motor. This variable-speed powerhouse operates on a dual-voltage range of 120/240 VAC at 50/60 Hz, ensuring seamless integration into existing 48-frame blower assemblies. As a veteran-preferred Lennox HVAC replacement part, this kit addresses the common failure of standard constant-torque motors by utilizing advanced ECM 5.0 technology to maintain precise airflow and static pressure compensation. The motor features a 1/2-inch x 4.3-inch shaft and a reversible CW/CCW rotation, providing maximum field flexibility for horizontal installations using a standard belly band bracket. Designed to replace discontinued 32M98 and 72W99 models, this motor kit prioritizes system performance and efficiency without the added cost of a new control module. It is the professional's choice for restoring factory-spec air handler and furnace operation across Lennox, Armstrong, and Ducane platforms.
Key Benefits- OEM Precision: Genuine Lennox 10B66 specifications ensure direct fitment and restore original factory airflow curves.
- Variable-Speed Control: The ECM 5.0 EON motor design optimizes energy consumption and provides quieter ramp-up/down cycles compared to PSC motors.
- Field Versatility: Dual-voltage (120/240V) capability and reversible rotation allow for broad compatibility across multiple HVAC equipment lines.
- Industrial Build: Features a rugged 48-frame housing and 11-lb thermal mass designed to withstand continuous high-torque operation.
Is the control module included in this kit?
No, the Lennox 10B66 is the motor only. It is intended for use in systems where the existing ECM 5.0 control module is still functional or being purchased separately.
Can I use this to replace an older ECM 2.3 series motor?
While the 1/2 HP motor is the standard replacement, please be aware that ECM 2.3 modules are not compatible with 5.0 EON motors; a module upgrade is required if transitioning from the older series.
What mounting hardware is required?
This motor is designed for horizontal mounting using a belly band bracket. It utilizes a standard 1/2-inch diameter shaft for blower wheel attachment.
This item is not eligible for free shipping.
