Heatcraft Refrigeration 5003LS Motor

The Heatcraft Refrigeration 5003LS Motor is a high-reliability, 1/2 HP replacement motor designed for heavy-duty commercial evaporator and condensing unit applications. Operating at 115V and 1050 RPM, this motor provides the necessary torque for consistent airflow in walk-in coolers and freezers. As a PSC motor (Permanent Split Capacitor), it maintains high operational efficiency under traditional refrigeration thermal loads. The CWSE rotation (Clockwise Shaft End) ensures compatibility with standard Heatcraft evaporator fan blades and blower assemblies.

When performing a field replacement, verify that the 115v 1/2hp 1050rpm specifications match the existing nameplate to ensure proper CFM delivery and prevent evaporator icing. This Heatcraft 5003LS unit is engineered to withstand the high-moisture environments typical of industrial refrigeration systems. For contractors, utilizing a genuine 5003LS motor ensures seamless mechanical alignment with Bohn, Larkin, and Chandler equipment without the need for mounting bracket modifications. This motor is a critical component for maintaining system superheat and preventing compressor liquid slugging through reliable air exchange.

Key Benefits

• Direct OEM Compatibility: Designed specifically for Heatcraft, Bohn, and Larkin refrigeration units to ensure a perfect mechanical fit.
• High-Torque Performance: The 1/2 HP 1050 RPM configuration provides robust airflow, essential for maintaining consistent box temperatures.
• Energy Efficient Design: Utilizing PSC motor technology reduces electrical consumption compared to standard shaded-pole alternatives.
• Rugged Construction: Built to handle the rigorous duty cycles and humidity levels of commercial walk-in refrigeration environments.

Common Questions

Is the 5003LS motor compatible with 208-230V systems?
No, this specific model is rated for 115V operation only. Installing it on a 230V circuit will cause immediate motor failure. Always verify your supply voltage before installation.

Which direction does the shaft rotate?
The 5003LS features CWSE rotation (Clockwise Shaft End). If your application requires CCW rotation, this motor will not be compatible with your existing fan blade pitch.

Does this motor require a capacitor?
Yes, as a PSC motor, it requires a specific run capacitor for operation. It is best practice to replace the capacitor whenever you install a new HVACR motor to ensure peak performance.
