Lennox 88C74 Fan Motor
For service calls requiring a robust replacement in high-static applications, the Lennox 88C74 is the definitive OEM condenser fan motor for restoring system pressure and thermal exchange efficiency. This industrial-grade 1HP 230V 1Ph motor is engineered specifically for Lennox and Allied equipment, ensuring the exact torque profile and RPM necessary to maintain factory-spec airflow. Operating at 1080 RPM with a 48Y frame, this motor provides the reliability needed for 24/7 demanding duty cycles. Known in technical catalogs as Lennox 88C7401, this unit features a 4.5-inch shaft length and standard CCWLE rotation, making it a direct-drop replacement that eliminates mounting headaches in the field. When performing this AC fan motor replacement, we recommend a fresh 10 MFD 370V/440V run capacitor to prevent premature winding failure and ensure optimal starting torque.
Key Benefits for Technicians:- Precise OEM Match: Fully interchangeable with Lennox 88C7401, ensuring zero-modification mounting and electrical compatibility.
- Optimized Thermal Performance: Rated at 1HP and 1080 RPM to handle high-ambient head pressures without tripping internal overloads.
- Durable Construction: Features a 48Y frame and a 4.5" shaft designed to withstand the vibration and exposure common in outdoor condensing units.
- Quiet Operation: Balanced internal components reduce harmonic noise and mechanical wear, extending the service life of the fan assembly.
Is the 88C74 compatible with the 88C7401?
Yes, these part numbers are technically identical and serve as direct replacements for the same Lennox condenser applications.
Should I replace the capacitor at the same time?
Standard field practice dictates replacing the run capacitor whenever a new condenser fan motor is installed. A weakened capacitor can lead to overheating and high-amp draws that shorten motor life.
What is the rotation for this motor?
This 1HP unit typically operates with a CCWLE (Counter-Clockwise Lead End) orientation. Always verify your specific fan blade pitch before finalizing the install.
