Trane MOT18681 Motor

The Trane MOT18681 is a professional-grade condenser fan motor designed for high-reliability performance in residential and light commercial HVAC systems. As a direct OEM replacement motor for the MOT10515 and MOT11447, this 48 frame motor ensures exact drop-in compatibility without the need for field modifications to mounting brackets or wiring harnesses. Engineered with a 1/8 HP output and a fixed speed of 1075 RPM, it maintains critical head pressure by providing consistent airflow across the condenser coils. This 200-230V, single-phase PSC motor features a Totally Enclosed Air-Over (TEAO) housing, protecting internal windings from moisture and debris in harsh outdoor environments. For a full system restoration, technicians should pair this motor with a new 5 MFD 370V run capacitor. Utilizing Class F insulation and a CCW lead end rotation, the Trane MOT18681 is the standard for maintaining factory-specified efficiency in Trane and American Standard condensing units.

• OEM Precision: Direct replacement for MOT10515, ensuring electrical and mechanical specifications match the original factory design.
• Enhanced Durability: The TEAO enclosure prevents environmental contaminants from entering the motor, extending service life in demanding climates.
• Optimized Cooling: Operates at a steady 1075 RPM to ensure proper heat dissipation and protect the compressor from thermal overload.
• Universal 48 Frame: Standardized NEMA dimensions allow for a seamless fit into existing belly band or stud mounts.

Is this a direct replacement for the MOT10515?
Yes, the MOT18681 is the current manufacturer-authorized replacement for the MOT10515 and MOT11447, featuring identical mounting and performance curves.

Does this motor include the run capacitor?
No, this motor requires a 5 MFD / 370V capacitor, which must be purchased separately. It is a best practice to replace the capacitor whenever a condenser fan motor is swapped.

Which systems are compatible with the MOT18681?
This motor is commonly found in Trane and American Standard 2TTA, 2TTB, and 4TTR series outdoor units requiring a 1/8 HP 1075 RPM specification.
