Trane MOT19479
The Trane MOT19479 is an OEM direct drive blower motor engineered for high-static pressure applications in residential and light commercial air handlers and heat pumps. This 1/5 HP blower motor operates at 208-230V single-phase power and maintains a consistent 1075 RPM to ensure optimal CFM delivery across the evaporator coil. Featuring a 48-frame diameter and an open air over (OAO) enclosure, this motor utilizes internal thermal overload protection to prevent winding failure during high-demand cycles. As a genuine Trane replacement part, it ensures precise mounting alignment and electrical compatibility, eliminating the vibration and performance drops often associated with universal aftermarket alternatives. Field technicians should note the secondary specifications, including the required run capacitor (refer to motor nameplate for MFD rating) and the clockwise lead end (CWLE) rotation, making it a critical component for restoring factory-standard airflow in Trane and American Standard systems.
Key Benefits for Technicians
- OEM Precision: Drop-in replacement for MOT19479 ensures the shaft length and flat-spot alignment match the existing blower wheel perfectly.
- Enhanced Efficiency: Optimized for 208-230V 1-Phase systems to maintain consistent torque and reduce amperage draw over the motor’s lifespan.
- Reliable Cooling: The OAO design utilizes the system's own airflow to dissipate heat from the motor windings, extending service life in tight cabinets.
- Simplified Installation: Standard 48-frame dimensions and factory-matched wiring harness reduce labor time during HVAC motor replacement.
Common Installation Questions
What is the frame size and shaft diameter of the MOT19479?
This motor features a standard NEMA 48 frame with a 1/2-inch shaft diameter, designed to seat securely in existing motor mounts without modification.
Do I need to replace the capacitor when installing this motor?
Yes, it is standard industry practice to install a new 370V run capacitor matched to the motor’s specific microfarad (MFD) requirements to ensure proper phase shift and starting torque.
Is this motor compatible with variable speed controllers?
The MOT19479 is a permanent split capacitor (PSC) motor designed for fixed-speed operation or multi-tap speed selection and is not a direct replacement for ECM or variable-speed modules.
