Trane Blower Motor MOT20546 ECM OEM

Trane MOT20546 ECM Blower Motor | 3/4 HP 120V Variable Speed OEM

The Trane MOT20546 is the genuine factory-authorized ECM blower motor and Eon VS assembly for Trane and American Standard variable-speed HVAC systems. This 3/4 HP high-efficiency motor is an Original Equipment Manufacturer (OEM) part, specifically programmed to maintain the precise airflow, efficiency, and communication standards required by your specific furnace or air handler.

As a premium Variable Speed motor, the MOT20546 operates at a maximum of 1200 RPM on a 120V power supply. Its advanced ECM technology allows for a "soft-start" ramp-up, which eliminates sudden air blasts, reduces mechanical stress on the blower wheel, and provides superior humidity control for a more comfortable indoor environment.

Compatibility & Cross-Reference

The MOT20546 is the official service replacement for several legacy and discontinued Trane part numbers. It is the required OEM match if your current motor or manual lists:

  • Replaces Trane / American Standard P/Ns: MOT16957, MOT21732
  • Factory Designation: Eon VS Motor - 7 Coefficient

Why Choose This Genuine OEM Motor?
