Trane Blower Motor MOT18955

Trane MOT18955 Blower Motor | 1/3 HP 200-230V 2-Speed PSC OEM

The Trane MOT18955 is a genuine factory-authorized PSC blower motor for Trane and American Standard equipment. This 1/3 HP motor is an Original Equipment Manufacturer (OEM) part, designed to meet the exact 1080 RPM and static pressure specifications required by your air handler or furnace.

As a 2-speed blower motor, it provides the specific high and low speed taps required for your system's airflow design. It is built in a standard 48-frame size, ensuring a direct fit without the need for bracket modifications in compatible units.

Compatibility & Cross-Reference

The MOT18955 is the official OEM replacement for several older part numbers and specific manufacturer models. Use this part if your unit specifies:

  • Manufacturer Equivalent: Emerson Model K55HXHPA-8618
  • Mounting Accessories: Compatible with RNG02600 mounting rings if required by your blower housing.
  • Verification: Due to variations in mounting, it is recommended to call with your Model Number to verify if your specific installation requires the KIT01052 mounting kit.

Important Installation: Choosing the Right Capacitor

A new run capacitor is required for a successful installation. The specific capacitor depends on the voltage of your system:

  • For 230V Systems: Use a P291-1254 capacitor.
  • For 200V Systems: Use a P291-2504 capacitor.
  • Why Replace? PSC blower motors rely on the capacitor for starting torque; using an old capacitor can cause the new motor to run hot or fail to start, which may void the manufacturer warranty.

Why Choose a Genuine Trane OEM Motor?

  • Exact Torque Profile: Matches the original factory airflow curves for consistent heating and cooling performance.
  • Durable Design: Precision-balanced to reduce vibration, which extends the life of both the motor and the blower wheel.
  • Simple Wiring: Features the original factory wire colors and connections for a straightforward "pull and swap" replacement.
