Trane MOT18954 Blower Motor | 3/4 HP 208-230V 3-Speed PSC OEM

The Trane MOT18954 is a genuine factory-authorized PSC blower motor designed for high-performance Trane and American Standard furnaces and air handlers. This 3/4 HP high-capacity Original Equipment Manufacturer (OEM) replacement is engineered to maintain the precise 1075 RPM and static pressure required for larger residential HVAC systems.

As a 3-speed blower motor, the MOT18954 provides the exact speed taps needed to match your system's original heating and cooling airflow requirements. Built with a heavy-duty 48-frame design, it ensures a direct mechanical fit and restores the factory-rated efficiency of your indoor unit.

Compatibility & Cross-Reference

The MOT18954 is the designated service replacement for several legacy and discontinued part numbers. It is the required OEM match if your current motor or manual lists:

  • Replaces Trane / American Standard Part Numbers: MOT11864, MOT02638, MOT03026
  • Direct Fit: Designed to replace original 3/4 HP motors with a standard 1/2" diameter shaft.
  • Verification: If you are unsure of the fit, we recommend checking the model and serial number on the unit's rating plate.

Important Installation Note: Run Capacitor

  • Required Capacitor: This motor requires a P291-2004 run capacitor (not included) for proper operation.
  • Proactive Replacement: It is a standard industry requirement to install a brand-new capacitor when replacing any PSC motor. Using an old or weakened capacitor can lead to overheating and will significantly shorten the lifespan of your new motor.

  • Factory-Specified Reliability: Unlike universal "will-fit" motors, this OEM part matches the exact electrical profile and torque curves of your original equipment.
  • Quiet & Balanced: Factory-balanced to minimize vibration and operational noise, ensuring a quieter home environment.
  • Easy Installation: Features the correct wire colors and mounting footprint to simplify the swap-out process for technicians or DIY homeowners.
