Trane MOT18975 – Genuine OEM Replacement Motor; 1/4 HP, 200-230 V, 48 Frame, 1075 RPM / 3 Speed

The Trane MOT18975 is a high-performance, three-speed direct drive blower motor engineered specifically for Trane and American Standard heating, air conditioning, and air handler systems. As a vital component of your equipment's indoor blower assembly, this motor plays a critical role in system safety and performance by facilitating the smooth and reliable operation required to push treated air through your home's ductwork. Maintaining a strong and properly functioning blower motor is essential for balanced temperature regulation, preventions against evaporator coil freeze-ups, and the overall efficiency of your system.

Operating on a 200-230V electrical configuration, this powerful 1/4 HP motor produces up to 1075 RPM with three distinct speed taps to scale perfectly with your thermostat's airflow demands. Opting for a Genuine OEM Trane replacement part matters immensely because it guarantees exact electrical compatibility and a precision fit within your existing 48-frame blower housing. This precise tolerance ensures no unwanted vibrations, significantly reduces bearing wear, and completely eliminates the guesswork or modification demands often required when resorting to generic aftermarket motors.

🛠️ HVAC Depot Pro Tip: Match Your Capacitor

When replacing a blower motor like the MOT18975, you should never reuse the old run capacitor. Over time, run capacitors lose their microfarad (MFD) rating, forcing the new motor to draw higher amps and overheat. Always install a brand-new capacitor (typically a 5 MFD / 370V capacitor for this specification, though you should check the label on the physical motor to verify) during installation to preserve your warranty and ensure a long-lasting repair.

Cross-Reference & Compatibility:

The MOT18975 is a direct OEM replacement for the following part numbers:

• OEM Numbers: MOT06061, MOT6061, MOT08493, MOT8493, MOT11993
• Aftermarket/Fasco: Multi-fit crosses can serve as substitutes, though physical dimensions and mounting should be double-checked to guarantee application fit.
