Lennox 28G88 Motor

The Lennox 28G88 is a high-performance direct drive condenser fan motor engineered for heavy-duty HVACR applications. Operating at 460V 1Ph, this 1/3 HP motor delivers a consistent 1075 RPM to ensure optimal head pressure control and thermal dissipation in commercial or residential condensers. This OEM replacement motor is electrically and physically identical to the legacy 28G8801, providing a seamless drop-in fit for technicians servicing Lennox-branded equipment.

Built on a standard 48 frame, the Lennox 28G88 motor features sleeve bearings for quiet operation and a PSC (Permanent Split Capacitor) design for enhanced electrical efficiency. The 1/2-inch diameter shaft and CCWLE (Counter-Clockwise Lead End) rotation meet the specific torque and airflow requirements of high-static environments. Designed for vertical mounting, this 1-speed unit requires a 7 MFD 370 VAC capacitor to maintain proper starting torque and long-term winding integrity.

• Direct Replacement: Fully compatible with systems requiring the 28G8801 part number without field modifications.
• Enhanced Durability: Robust 48 frame construction withstands the high-heat cycles typical of outdoor condenser units.
• Broad Compatibility: Standardized 460V single-phase electrical specifications fit a wide range of Lennox commercial rooftop and split system configurations.
• Efficient Airflow: Sustained 1075 RPM output ensures the heat exchanger maintains the necessary Delta T for efficient cooling cycles.

• Is the 28G88 compatible with the 28G8801? Yes, these are identical parts; the 28G8801 is the previous revision of the current 28G88.
• What type of capacitor is required for this motor? A 7 MFD / 370 VAC run capacitor is required for proper operation and to prevent winding failure.
• Can this motor be used in a horizontal application? This specific model is designed for vertical mounting positions, which is standard for most Lennox condenser fan configurations.
