Lennox 12W70 Motor
The Lennox 12W70 is a high-performance direct drive blower motor engineered for specific Lennox furnace and air handler applications. Integrated into a 48-frame motor configuration, this 1/2 HP replacement motor operates on 208-230V single-phase power at 825 RPM. As a PSC (Permanent Split Capacitor) motor, it utilizes two distinct speed taps to optimize airflow across various heating and cooling stages, ensuring proper static pressure management. Built with all-angle sleeve bearings and a robust TEAO (Totally Enclosed Air Over) enclosure, this motor is designed to withstand the thermal stress of continuous duty cycles in high-demand residential systems. When performing an HVAC blower motor replacement, verify that your run capacitor (typically 10MFD/370V) is tested and replaced if necessary to prevent premature winding failure. This 1270 motor provides the necessary torque and RPM stability required to maintain factory-spec CFM across the evaporator coil.
Key Benefits
- Lennox OEM compatibility ensures exact mounting alignment and electrical wiring harness integration.
- Dual-speed operation allows for precise airflow tuning to meet specific system tonnage requirements.
- Sleeve bearing design provides quiet operation and reduced vibration levels within the blower housing.
- Reversible rotation or fixed CCWLE/CWLE configuration (verify lead wires) supports versatile furnace orientations.
- Professional grade insulation Class B rating protects electrical integrity under standard operating temperatures.
Common Questions
What capacitor does the Lennox 12W70 require?
This motor typically requires a 10 MFD at 370V run capacitor. Always check the nameplate on the original 12W70 motor to ensure the capacitance rating matches your system configuration.
Can I use an 1100 RPM motor to replace this 825 RPM model?
No. Increasing the RPM will significantly increase the amperage draw beyond the motor’s rated capacity and may cause the blower wheel to become unstable or noisy. Stick to the 825 RPM specification for this assembly.
What are the symptoms of a failing 1/2 HP blower motor?
Common indicators include a humming sound without fan rotation, intermittent thermal tripping, or excessive heat radiating from the motor casing, often caused by seized sleeve bearings or a degraded capacitor.
