Why does your ceiling fan makes a buzzing sound?

Answer 1

There are many reasons why your ceiling fan could buzzing. One reason can be losse screws. Tighten the screws in the blades. If you have found the screws are loose in the blades, this could be the main cause or only cause of your problem.

Answer 2

Most ceiling fans make a humming noise. If you feel the humming noise is unusual, you should check how attached the fan is to the ceiling, as the vibration of the fan can cause a humming noise.

Answer 3

If the fan part of the ceiling fan is controlled by a dimmer switch, that is sometimes why it makes noises and buzzing because it's being set at a desired point than what the ceiling fan's motor is used to, replace the dimmer switch with a standard light switch and use its pull chain to select a desired setting.

Answer 4

This commonly happens when using dimmers. Dimmer wall controls are made to control lights and may cause your fan to hum. We DO NOT recommend the use of dimmers to control fan speed. You should remove the dimmer switch and replace it with a standard speed control. Another possibility is that you have a bad receiver. If you are using a remote control, remove the receiver and connect the fan directly to power. If the noise goes away, your issue is a bad receiver. Your ceiling fan might have bad capacitors. Try changing the switch cup and/or capacitors. If the fan is also running slowly, the voltage level that the fan is receiving may be low, causing the motor to struggle. Voltage levels below 105 volts A/C will cause noise. If you have multiple fans on the same controller or same circuit, this could be the noise culprit. Fans used in tandem with other fans on a wall controller tend to be more prone to noise. Especially in older homes, many rooms are on the same branch circuits. This can cause a low voltage to be present which will cause a fan to make noise and run slowly.
