Carrier RTU Blower Motor 240138 5 HP 1800 RPM

Carrier 240138 Blower Motor | 5 HP OEM

The Carrier 240138 is a genuine factory-authorized heavy-duty blower motor designed for commercial Rooftop Units (RTU), large air handlers, and packaged systems. As an Original Equipment Manufacturer (OEM) component, it is engineered by Carrier/Nortek to meet strict industrial performance standards.

This 5 HP motor operates at a nominal 1800 RPM and features a triple-voltage capability (208-230/460V), making it highly versatile for various commercial electrical configurations. Its 184T frame is a NEMA standard, ensuring that the mounting feet and shaft dimensions align perfectly with original equipment specifications for a "drop-in" replacement.

Compatibility & Cross-Reference

The 240138 is the primary service part for a variety of high-capacity commercial HVAC systems:

• Directly Replaces Part Numbers: Marathon GT0013A
• Manufacturer Reference: Possible cross for Century/Genteq models like the E219M2.
• Equipment Fitment: Standard on many Carrier, Bryant, and Payne large-tonnage commercial rooftop units.
• Broad Brand Support: Also serves as a factory replacement for industrial units under the Day & Night and Heil brands.

Technical Specifications

Why Choose a Genuine Carrier OEM Motor?

• Three-Phase Efficiency: Built for industrial duty cycles, the three-phase design provides smoother operation, lower vibration, and higher starting torque compared to single-phase alternatives.
• Open Drip-Proof Design: The DPAO enclosure is specifically designed to be cooled by the system's own airflow, ensuring the motor stays within its rated temperature rise even during continuous operation.
• Precision Shaft Alignment: The keyed 1-1/8" shaft is machined to tight tolerances to ensure perfect coupling with the blower pulley, reducing wear on the drive belt and bearings.
• Rugged 184T Frame: The cast or heavy-gauge steel frame provides the necessary rigidity to support a 5 HP load without flexing, which is critical for maintaining belt tension and alignment.
