Mount 7–8 feet above the floor—use a flush-mount or low-profile hugger fan to avoid head bumps.

Check the circuit breaker, wall switch, and fan wiring. If the motor hums but doesn't spin, the bearings may be seized and need lubrication or replacement.

Loud noise often means dirt buildup, loose parts, or a failing motor. Tighten screws, clean the fan, or replace it with a low-sone (quiet) model.
