FAQ

This motor assembly is compatible with NuTone and Broan bath fan models including NuTone 8663RP, 8664RP, 8673RP, 671R, 672R, 8663RF, 8663RFT, 8663RLG, 8663RMAB, 8663RMBR, 8663RMS, 8663RMSA, VL3668RLG, VL3668RMAB, VL3668RMBR, VL3668RMSA, and VL3668RP, as well as Broan 750, 751, 752, and N750. Because bath fans can vary by production revision, match your existing part number and motor configuration before ordering.
This assembly replaces part numbers 97017705 and S97017705, as well as motor numbers 86933000 and JA2B104N. It also serves as a direct replacement for S97017703, S97017704, S97017706, S97017707, S97017708, S97017709, JA2C271G, JA2B099N, JA2C395N, and 89615000. Verify the number on your original motor or fan parts list to confirm fit.
Typical symptoms include the fan humming but not spinning, slow startup, excessive squealing or grinding, overheating smell, intermittent operation, or noticeably weak airflow even after the grille and blower wheel are cleaned. If the wheel turns stiffly by hand with power disconnected, worn motor bearings are a common cause.
For most compatible NuTone and Broan bath fans, installation is a straightforward repair taking about 20 to 45 minutes. Common tools required are a screwdriver, needle-nose pliers, and possibly a nut driver. Always shut off power at the breaker first, remove the grille, unplug or disconnect the motor, transfer the blower wheel if required, and reinstall the assembly in the same orientation as the original.
Before installing the new motor, inspect the blower wheel for cracks, rubbing, or heavy dust buildup, and clean the housing and duct opening so restricted airflow does not overload the new motor. Also check that the fan blade or wheel spins freely, the mounting plate matches your original setup, and the plug style and shaft arrangement are the same as the old unit.
This motor features a 2-prong plug, 115-120V, 60Hz operation, and runs at approximately 1550 RPM. It includes a 1/4 inch x 1 inch shaft and utilizes CCW rotation. To ensure a perfect fit, compare your original motor's label, connector style, shaft size, and mounting arrangement before purchase.
