    Where the fan rotates there is usually a shaft and bearing.  Should turn smoothly.  Needs cleaning and lubrication if it can or replacement if it can't.

    Take it down, clean it well then apply a few drops of motor oil to both ends of its shaft at the moving blades area. That shall fix it well, repeat this task yearly.
