Trane MOT18625 Motor

The Trane MOT18625 Motor is a high-performance 1/4 HP condenser fan motor engineered for demanding outdoor HVAC applications. Operating at 200-230V and a specialized 825 RPM, this 48-frame motor is the factory-spec OEM replacement motor for several legacy part numbers, ensuring a drop-in fit for Trane and American Standard residential condensing units and heat pumps. This single-phase, TEAO (Totally Enclosed Air-Over) motor is built for continuous duty and features a 0.5-inch shaft diameter with a counterclockwise lead-end rotation (CCWLE). By matching the original 825 RPM fan motor specs, you preserve the exact static pressure and airflow profiles required for optimal thermal heat exchange and compressor protection. For a complete condenser motor repair, it is highly recommended to replace the 7.5 MFD 370V/440V capacitor simultaneously to prevent premature winding failure and ensure proper start torque.

• Verified Compatibility: Direct cross-reference for MOT08914, MOT10479, MOT8914, MOT3419, and X70370551010.
• Precision Speed Rating: The 825 RPM output maintains factory-calibrated airflow over the condenser coils.
• Industrial Build Quality: Features a moisture-resistant 48 frame housing designed for vertical-shaft mounting in harsh environments.
• Integrated Thermal Protection: Superior internal thermal overload protection prevents burnout during high-ambient operation.

What capacitor is required for the MOT18625?
This motor typically requires a 7.5 MFD / 370-440 VAC run capacitor (sold separately) to maintain the magnetic field and efficiency for its 1/4 HP load.

Can I use an 1075 RPM motor as a substitute?
No. Moving from an 825 RPM motor to a 1075 RPM motor will increase fan blade noise, significantly raise amperage draw, and potentially overload the motor or affect the system's subcooling and head pressure.

What is the rotation direction of this unit?
The Trane MOT18625 is set for CCWLE (Counterclockwise Lead End) rotation, which is standard for most Trane condenser fan replacement projects.
