FAQ

This motor assembly is commonly listed for Broan and NuTone bathroom exhaust fans that use an 8 in. x 8-1/4 in. mounting plate and 110 CFM / 4 sone blower setup. Reported compatible models include 674, 674-A, 676, 676-D/2676F-A, 680, 680-A/2680F-A, 680FL, 680FLT, FL2680F, 684NT-A, 684-D/2684F-A, 672SP, 646D, 110RDB, 110RDF, NT100C, DX90, DX110, HD50, 678-G, 683-C, and 683L-A. Because fan housings and assemblies can vary by revision, match both the part number and the mounting plate size before ordering.
The main replacement number is S97015157. A commonly referenced equivalent format is 97015157. Always verify the number on your original assembly label if it is still readable.
This is generally sold as a complete blower/motor assembly rather than just a bare motor. It is commonly described as including the motor, blower wheel or impeller, mounting plate, and wired capacitor. That makes it useful when the wheel is damaged or when you want to replace the full removable assembly instead of rebuilding the old one.
Commonly reported specs for this assembly are 120V AC, 60 Hz, about 0.19 amps, 1500 RPM, 110 CFM airflow, 4 sones sound level, and CCW shaft rotation. The mounting plate is approximately 8 in. x 8-1/4 in., and the blower wheel diameter is commonly listed around 5-1/2 in.
Typical symptoms include a loud humming or grinding noise, slow startup, poor airflow at the grille, intermittent operation, overheating smell, or a fan that spins only when pushed by hand. If the blower wheel is cracked or rubbing the housing, replacing the full assembly is often easier than trying to repair individual pieces.
Installation is usually a moderate DIY job. In many Broan/NuTone units, the grille comes off first, then the removable blower assembly is unplugged or disconnected and taken out from below the ceiling. Basic tools typically include a screwdriver, work gloves, and possibly needle-nose pliers. Expect roughly 20 to 45 minutes if the old assembly comes out easily. Turn off power at the breaker first, and compare the wire connection style and mounting plate orientation before installing the new assembly.
Before installing a new assembly, clean out dust buildup, inspect the duct for blockage, and make sure the damper flap opens freely. Also check that the fan housing matches the 8 in. x 8-1/4 in. plate size and that your old unit is a 110 CFM / 4 sone style. Excess lint, bent blower wheels, or a blocked duct can cause noise and weak airflow even when the motor itself is still working.
