Fan control receiver

If your ceiling fan has a control system that includes a receiver, a faulty receiver can cause a humming noise. Check that you are using a control system that is compatible with your specific fan model

Due to dust

The motor has not been cleaned for a long time to clean the dust, so the operating parts are no longer smooth

Due to running out of lubricating oil

Make the engine stuck

Check engine mount

There are many brackets that do not meet the vibration needs of the motor or it is too old, choose a bracket that is suitable for the weight and size of the fan.

Defective dimmer

Dimmable switches often produce a noisy electrical sound.

Missing screw

This is a high cause of noise because it encourages unstable internal components

There is an Error in the Speed Settings.

One possibility is that there is an error in the speed settings. If the fan is set to run at a higher speed than it is rated for, it can cause the motor to overheat and make a humming noise.

The Nuts and Bolts Are Loose.

Another possibility is that the nuts and bolts holding the fan together are loose. This can cause the fan to vibrate and make a humming noise.

Because There Is Not Sufficient Lubrication

The blades of the ceiling fan need to be lubricated in order to run smoothly. The bearings in the motor may also need to be lubricated.

If they are not properly lubricated, they can make a humming noise.

Installation is not ready

Sometimes the mount is to blame for the buzzing sound coming from the ceiling fan. It’s possible for loose screws or other bits and pieces of the fan to get lodged within the mounting box.

They have the potential to move about and make an obnoxious rattling noise while the fan is running.


If the blades of the ceiling fan are not properly balanced, it can cause the fan to wobble and make a humming noise. The blades may need to be tightened or loosened in order to achieve the proper balance.

F.A.Q How to stop ceiling fans from humming

Why is my ceiling fan generating a buzzing noise?

The vibration of the motor in a ceiling fan is often what causes the hum heard from the fan, and the mount, housing, and blades of the fan all contribute to the overall loudness of the noise. There are components in many contemporary fans that muffle the hum, but there are also instances when these pieces break.

How can I get rid of the buzzing sound that a ceiling fan makes while it is operating on an inverter?

However, if the buzzing sound is making you feel uneasy, you may want to consider upgrading your current inverter to one that has a higher quality and is closer to producing a sinusoidal supply of alternating current (AC). The noise from the ceiling fan will be reduced but cannot be eliminated entirely.

Can I lubricate a ceiling fan?

Ceiling fans, like any equipment with moving components, need the appropriate lubrication in order to function correctly. According to Flush Mount Ceiling Fans, some of the more recent fan types are self-lubricating and don’t need any care on your part, while other versions require fresh oil to be poured once per year.

Is it possible to spray WD-40 on the ceiling fan?

Because it is not an effective lubricant, it is not recommended to use WD-40 to grease the bearings of a ceiling fan. The primary functions of WD-40 are those of a solvent and rust remover.

If you put it on a ceiling fan, it could quiet it for a little time, but it will dry out quickly and lead to additional issues if you do so.


Ceiling fans are a great way to keep your home cool in the summer, but they can be annoying when they start humming. If you have a ceiling fan that’s been driving you crazy with its noise, there are several things you can do to stop it from humming.

We’ve put together a list of tips that should help you fix the problem and get your ceiling fan back to working quietly and efficiently.
