Trane KIT19855 277V BLDC Motor Upgrade Kit for UniTrane Fan-Coil Units

The Trane KIT19855 is a 277V brushless DC (BLDC) motor upgrade kit designed to modernize existing Trane UniTrane fan-coil and Force-Flo air conditioning units. This comprehensive retrofit solution transforms traditional multi-speed permanent split capacitor (PSC) motors into high-performance, energy-efficient BLDC systems.

Complete Upgrade Package Includes:

• Brushless DC motor with integrated electronics
• ECM engine module for precise control
• Universal adapter board for compatibility
• Pre-configured wire harness assembly
• Mounting bracket and hardware

Key Features and Benefits:

• Variable-speed control for enhanced comfort and efficiency
• Significantly reduced energy consumption compared to PSC motors
• Quiet operation with minimal noise and vibration
• Integrated overload and short circuit protection
• Single plug connection simplifies installation
• Factory configured for clockwise rotation (single-shaft models)

This kit serves as the updated replacement for the obsolete KIT16210 upgrade kit. The BLDC motor is voltage-configured using an external jumper on the motor connector—for 277V applications, the jumper between pins 2 and 6 must be removed to prevent damage to motor electronics. The motor supports speeds down to 450 RPM and delivers outstanding comfort, safety, and performance while lowering operating costs.
