Lennox 38W83 Motor

The Lennox 38W83 motor is a direct-drive 1/15 HP condenser fan motor designed for high-performance heat pump and cooling applications. Operating at 208-230V and 1075 RPM, this PSC motor requires a 3 MFD at 370V capacitor for optimal torque and heat dissipation. Built with a 48-frame diameter and an enclosed design, it is engineered to withstand harsh outdoor environments while maintaining consistent airway clearance. As a core Lennox replacement part, it ensures precise rotation speeds and thermal protection for critical system cooling. When replacing an OEM condenser fan motor, verify the shaft length and lead wire configuration to ensure a seamless drop-in fit. This motor is a standard stock item for technicians servicing residential units where energy efficiency and low-noise operation are non-negotiable requirements for long-term system reliability.

• OEM Reliability: Direct replacement for several Lennox and Allied Air units, ensuring electrical and physical compatibility without field modifications.
• Optimized Performance: Engineered for 1075 RPM to provide the exact CFM required for efficient refrigerant heat exchange.
• Thermal Protection: Features internal overload protection to prevent winding failure during high-ambient operation.
• Application Versatility: Suitable for both air conditioning and heat pump systems requiring a 208-230V single-phase motor.

Common Questions

What capacitor is required for the Lennox 38W83?
This motor utilizes a 3 MFD / 370V run capacitor. Utilizing an incorrect rating may lead to overheating or premature failure of the start windings.

Is this motor compatible with 115V systems?
No, this is a 208-230V motor specifically. Applying 115V will cause the motor to fail to start or pull excessive amperage, resulting in damage.

Can this motor be used in a horizontal or vertical orientation?
Yes, the ball bearing or sleeve bearing configuration in these OEM Lennox motors generally allows for multi-positional mounting, provided the drain plugs are positioned correctly to prevent moisture ingress.
