Trane MOT3474 Motor
When you are dealing with a furnace or air handler that has lost its draft or circulation, the Trane MOT3474 Motor is a critical OEM replacement motor designed to restore factory-spec performance. This 1/20HP furnace motor operates on a standard 115V single-phase power supply, delivering a consistent rotational speed of 3200 RPM. Built by Fasco (model 71218540) for Trane and American Standard, this unit features a clockwise (CW) rotation and a 3.3-inch diameter frame, making it a drop-in solution for specific draft inducer and combustion fan applications. The motor utilizes sealed ball bearings for high-speed stability and is thermally protected to prevent winding burnout during continuous regional heat cycles. As a veteran in the field, you know that matching the full load amps (1.3/0.7A) and shaft dimensions is non-negotiable for system safety; the MOT3474 ensures your HVAC induction blower draws exactly what the control board expects, preventing nuisance trips and premature component fatigue.
Key Benefits- OEM Compatibility: Exact replacement for Service First MOT03474, ensuring mounting holes and belly band positions align without modification.
- High-Speed Efficiency: Rated at 3200 RPM to maintain the precise static pressure required for safe combustion venting.
- Industrial Build Quality: Features Class B insulation and an air-over (A-O) cooling design for reliable operation in high-ambient furnace cabinets.
- Durable Support: Equipped with sealed ball bearings that require zero maintenance and provide a longer service life than standard sleeve bearings in high-RPM kits.
Is this motor reversible?
No, this specific model is fixed for clockwise (CW) rotation as viewed from the lead end. Always verify your existing blower wheel direction before installation.
Does this motor require a run capacitor?
The Trane MOT3474 is typically a shaded-pole or permanent split motor design that does not require an external capacitor, though you should always check the original wiring harness for any secondary components.
Can I use this for a 230V system?
Negative. This is a 115V AC motor. Applying higher voltage will result in immediate failure of the internal windings and thermal protection.
