Trane MOT18679 Motor

The Trane MOT18679 Motor is a high-performance OEM replacement motor engineered for precision airflow in residential and light commercial HVAC applications. Operating at 200-230V with a 1/5 HP rating, this single-phase component delivers a consistent 1080 RPM to maintain system static pressure and efficiency. As the primary MOT10331 replacement, the MOT18679 features a 48-frame chassis with a Totally Enclosed Air-Over (TEAO) enclosure, providing critical protection for internal windings against dust and moisture in the airstream. Designed with Class F insulation and a CCWLE rotation (Counter-Clockwise Lead End), this motor ensures seamless integration into existing Trane condenser fan and blower assemblies. Technicians can rely on its 1/2-inch shaft diameter and standard mounting configuration for rapid field installation, reducing downtime while restoring the original equipment manufacturer's performance specifications. This robust motor is also a verified substitute for obsolete part numbers MOT4104 and MOT6613, offering a versatile solution for legacy system maintenance.

• Direct OEM Compatibility: Serves as the factory-authorized MOT10331 replacement to ensure exact fitment and electrical alignment.
• Enhanced Environmental Protection: The Totally Enclosed Air-Over (TEAO) design prevents debris from entering the motor housing, extending service life in demanding conditions.
• High-Efficiency Performance: Calibrated for 1080 RPM at 200-230V, optimizing energy consumption while maintaining required CFM.
• Industrial-Grade Build: Utilizes Class F insulation and durable bearings to withstand high thermal loads during continuous operation.

Common Questions

What capacitor is required for the MOT18679 motor?
This motor typically requires a 7.5 MFD / 370V run capacitor for proper startup and operational torque. Always verify the capacitor rating on the motor nameplate during installation.

Can this motor replace an older MOT4104 or MOT6613 model?
Yes, the MOT18679 is the current technical successor for MOT10331, MOT4104, and MOT6613, maintaining the same 48-frame mounting and 1/5 HP specifications.

Is the rotation reversible on this unit?
No, this specific motor is fixed for Counter-Clockwise Lead End (CCWLE) rotation. Verify your fan blade pitch and system requirements before installing.
