Lennox 12W65 Blower Motor
The Lennox 12W65 Blower Motor is a high-performance 1/4 HP 240V replacement motor designed for precise airflow management in residential air handlers and furnaces. As an essential HVAC blower motor replacement, this unit operates at a nameplate 825 RPM with a dual-speed configuration, allowing for adaptable system performance and improved efficiency. Built by US Motors (Model K55HXLMW-0158), it features a NEMA 48Y frame and a 1/2-inch diameter shaft, ensuring a direct fit for compatible Lennox, Allied, and Armstrong equipment.
This OEM Lennox motor utilizes a permanent split capacitor (PSC) design, requiring a 15 MFD at 370VAC capacitor for optimal startup and operation. The counter-clockwise lead end (CCWLE) rotation and thermally protected internal windings provide the durability required for continuous "air over" applications. For contractors performing a furnace blower motor repair, the 12W65 offers a reliable solution to restore system static pressure and maintain specified CFM delivery across the heat exchanger or cooling coil.
Key Benefits
- Exact OEM Compatibility: Designed specifically for Lennox CB26UH and CBX26UH series air handlers, eliminating mounting field-modifications.
- Dual-Speed Versatility: Supports 2-speed operation to balance dehumidification and heating requirements effectively.
- Enhanced Durability: Features self-aligning ball bearings and Class B insulation for stable performance in high-temperature environments.
- Thermal Protection: Integrated internal hit-protection prevents winding burnout during restricted airflow conditions or high-static loads.
Common Questions
What are the signs that a Lennox 12W65 motor needs replacement?
Technicians typically check for seized bearings (squealing or grinding), high amperage draw exceeding the 1.4A rating, or a failed winding test (resistance to ground). Reduced airflow or a humming sound without rotation often indicates a failed capacitor or a compromised motor start winding.
Is the capacitor included with this blower motor?
The motor is sold as a standalone unit. It is standard professional practice to install a new 15 MFD / 370V capacitor whenever replacing the motor to ensure the start circuit operates within factory parameters.
Can I use this motor to replace a different brand with similar specs?
While the 1/4 HP and 240V ratings are common, this motor uses a specific 48Y frame and CCWLE rotation. Always verify the shaft length (4 inches) and mounting bolt pattern before attempting a cross-brand installation.
