Trane MOT18960 Motor

The Trane MOT18960 Motor is a high-performance, 1/8 HP OEM replacement engineered specifically for light commercial and residential fan coil applications. Operating at 277V (265V utilization voltage), this 42-frame HVAC motor delivers a constant 1050 RPM with three distinct speed taps, allowing for precise airflow adjustment across multi-speed blower assemblies. This unit serves as a critical HVAC blower motor replacement, ensuring efficient heat transfer and proper static pressure management within Trane and American Standard air handlers.

For contractors performing maintenance or repairs, identification remains straightforward: the MOT18960, often paired with the KIT2411 belly band kit, is the direct technical replacement for the legacy MOT4598 and 42FK64 models. Featuring an Open Air-Over (OAO) enclosure and a robust 1/2-inch diameter shaft, it is designed for continuous duty cycles. Integrating a genuine Trane OEM motor ensures electrical compatibility with existing control boards and capacitor requirements (typically 5 MFD), preventing the premature shaft wear or overheating common with universal alternatives.

• Precision 3-Speed Control: Provides versatile 1050/900/700 RPM settings to match specific system requirements.
• Direct OEM Compatibility: Engineered as the primary MOT18960 service part to replace outdated MOT4598 units without field modifications.
• Industrial Build Quality: Features Ins. Class F insulation and a 42Y frame for reliable operation in demanding ventilation environments.
• Efficient Thermal Management: Open Air-Over design utilizes system airflow to maintain optimal operating temperatures.

Common Questions Regarding the MOT18960

Is this motor compatible with 230V systems?
No, this motor is specifically wound for 277V AC service voltage; using it with lower voltage will lead to torque failure and winding damage.

Does this replacement include the mounting bracket?
The MOT18960 is a motor-only unit; if your existing mount is damaged, the KIT2411 belly band is the recommended mounting solution.

Can I use a different capacitor than the one specified?
It is critical to use the manufacturer-specified 5 MFD oval or round run capacitor to ensure correct phase displacement and motor longevity.
