the fan flanges to the motor hub are tight.
Make sure main power is turned OFF.
3. Check to make sure wire connectors in switch
housing are not rattling against each other or
against the interior wall of the switch housing.
4. Some fan motors are sensitive to signals from
solid-state variable speed controls. If solid-state
control is used and motor noise results, choose
an alternative control method.

1. Tighten both set screws securely in the motor
coupler.
2. Tighten the set screw in the hanger ball/
downrod assembly.

pair can redistribute the weight and result in
smoother operation.
