Nidec-US Motors N157 Inducer Motor

When you're troubleshooting a failed furnace exhaust system, the Nidec-US Motors N157 Inducer Motor is a rugged, industry-standard choice for draft inducer applications. This 1/30HP furnace inducer motor operates at 3000 RPM on a 120Vac (115V nominal) power supply, pulling a consistent 1.6 Amps. Designed as a direct OEM replacement motor, it features a shaded pole motor design and is thermally protected with an automatic reset to prevent burnout during stalled-rotor or overload conditions. For the service tech, this unit replaces Fasco A157, Goodman 7002-2307, and Dayton 4MH09, making it a highly versatile part for your truck stock. The open enclosure allows for maximum heat dissipation, while the specific configuration ensures precise airflow for efficient combustion and venting. This draft inducer blower motor provides the reliable torque and high-speed operation required to prevent pressure switch trip-outs in residential heating systems.

• Direct OEM Compatibility: Replaces common Goodman, Fasco, and Dayton models, reducing downtime on the job site.
• Heavy-Duty Construction: Built with ball bearings or high-grade sleeve bearings and thermally protected windings for increased service life.
• Complete Kit: Typically includes the necessary gasket to ensure a gas-tight seal upon installation.
• Standardized Specs: Operates at a steady 3000 RPM to maintain correct static pressure for furnace safety circuits.

Is the Nidec N157 a direct swap for my Goodman inducer?
Yes, the N157 is specifically cross-referenced for multiple Goodman part numbers including B1859005 and 7021-8556. Always verify the motor height and mounting bolt pattern before installation.

Does this motor include the cooling fan or internal wheel?
This is an assembled draft inducer assembly replacement, usually including the motor and the blower housing components required for the specific exhaust path.

Can I use this 120V motor on a 208-230V system?
No. This motor is strictly rated for 120Vac (115V). Applying higher voltage will result in immediate winding failure and potential safety hazards.
