Trane Blower Motor MOT18949

Trane MOT18949 Blower Motor | 1/2 HP 115V 4-Speed PSC OEM

The Trane MOT18949 is a genuine factory-authorized PSC blower motor engineered for Trane and American Standard furnaces and air handlers. This 1/2 HP high-performance Original Equipment Manufacturer (OEM) replacement is designed to deliver the exact 1075 RPM and static pressure capabilities required to maintain your system's original airflow efficiency.

As a 4-speed induction motor, the MOT18949 provides the necessary speed taps to match your system’s specific heating and cooling airflow requirements. Built in a standard 48-frame housing, this motor ensures a seamless mechanical fit and restored reliability for your HVAC unit.

Compatibility & Cross-Reference

The MOT18949 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 P/Ns: MOT08537, MOT11992, D340988P02
  • Manufacturer Equivalent: Emerson Model K55HXHKL-8719
  • Direct Replacement: Specifically matched for units requiring a 1/2 HP 115V PSC motor with a 1/2" diameter shaft.

Important Installation Note: Run Capacitor

  • Required Capacitor: This motor requires this P291-1504 Run Capacitor for proper starting and operation.
  • Sold Separately: Please note that the capacitor is not included with the motor. It is highly recommended to install a brand-new capacitor when replacing any PSC motor to ensure the longevity of the new component.
