Lennox 27H33 Motor

For field technicians and contractors maintaining Lennox units, the Lennox 27H33 is the essential OEM condenser fan motor for ensuring reliable heat rejection. This PSC (Permanent Split Capacitor) motor is engineered to handle the rigorous duty cycles of outdoor condensing units, delivering 1/6 HP at a steady 825 RPM. Operating on 208-230V single-phase power, it provides the precise torque and airflow required to maintain head pressure within manufacturer specifications. The motor features a 48 frame size, a 2.5-inch shaft length, and is designed for vertical mounting with CCWLE (Counter Clock-Wise Lead End) rotation, making it a drop-in replacement for numerous Lennox and Airflo cooling systems.

Maximizing the lifespan of this direct-drive motor requires a 5 MFD 370 VAC capacitor (sold separately) to ensure proper starting torque and phase displacement. Its rugged construction is optimized for high-temperature environments, preventing premature winding failure. When replacing a seized or noisy motor, verify the 60 Hz frequency and single-phase wiring compatibility to avoid control board errors or thermal overloads. Choosing Lennox factory-authorized parts like the 27H3301 ensures that your system maintains its original SEER rating and operational efficiency without the compatibility risks inherent in universal aftermarket alternatives.

• OEM Compatibility: Precision-matched for Lennox condenser units, ensuring exact fitment without bracket modification.
• Efficient Airflow: The 825 RPM low-speed design reduces operational noise while effectively pulling heat across the condenser coils.
• Industrial Build: Rated for outdoor use with high-grade insulation to resist moisture and temperature fluctuations.
• Optimized Performance: This 1/6 HP motor maintains consistent airflow, crucial for protecting the compressor from liquid slugging or high-head pressure.

What capacitor is required for the Lennox 27H33?
This motor requires a 5 MFD / 370V capacitor for proper operation. Using an undervalued or worn capacitor will cause the motor to overheat and fail prematurely.

Can this motor be used in horizontal applications?
No, the 27H33 is specifically engineered for vertical mounting positions. Using it horizontally can lead to improper bearing lubrication and shortened mechanical life.

Does this motor include the rain shield?
Standard Lennox 27H33 units typically do not include a pre-installed rain shield; ensure the existing shield is transferred or a new one is installed to protect the motor bearings from moisture.
