Ceiling fan is an indispensable electrical appliance in every home. However, after a period of use, the ceiling fan phenomenon makes annoying noises. Instead of inviting a mechanic to fix these common minor errors at an expensive price depending on the repairman, you can completely fix them yourself. Toby Nwazor will show you how to stop the noise of the ceiling fan on the website https://ceilingfanswiki.com/, and show you how to fix common ceiling fan errors.
Technical information of ceiling fan
Before learning and repairing the noise of a ceiling fan, let’s learn how it works.
This part creates rotation for the fan, there are 2 main types: capacitor and short circuit type. To protect the electric motor it is placed inside the fan’s bulb.
Air generating unit, usually made of materials such as plastic, alloy, wood, fiberglass. Fans usually have 3, 4, 5 blades and are attached to the light fan with screws and brackets.
This is the part used to adjust the wind speed of the ceiling fan. Ceiling fans usually have 3-9 wind speeds.
In the structure of ceiling fan. This is the part that connects the ceiling fan’s wiring to the indoor wiring located on the ceiling.
Ceiling fan hanger
The part used to hang the fan to the ceiling.
This is the part used to cover the hangers or screws and electrical boxes on the ceiling.
Ceiling fan hook
An indispensable part when installing a ceiling fan, connecting the fan to the pillar.
Working principle of ceiling fan
- The power supply helps to start and turn the motor.
- Then the electric motor will start to rotate in the set direction depending on the speed parameter selected by the user.
- The active motor will rotate the propeller when the motor receives operation control, the rotor mounted on the rotor will also rotate in the set direction.
- Then the fast / slow air flow will be based on the motor speed set by the controller according to the previous setting.
Smart and modern features of ceiling fans
The structure of a ceiling fan is similar to that of a traditional fan. However, this product has an additional lighting function with a variety of lights placed under the propeller system; meet the needs of cold lighting and add aesthetics to the space.
Tele fan remote
Ceiling fan has a remote control that allows users to easily turn on and off the fan or adjust the wind mode. At the same time, you can also adjust the wind speed or schedule the fan to turn off from any position without having to move the light switch.
This is an integral part of the ceiling fan and usually comes with it, so you won’t have to buy it extra. The structure of the gearbox basically consists of an inner and an outer gearbox with a governor, a motor system, a cluster and a cylinder.
However, the ceiling fan emitting noises can also come from these modern items. For example, when turning the fan, it accidentally hits the light on the bottom
Why does the ceiling fan make noise?
This noise has a significant impact on family life. Make people in the house feel uncomfortable. Especially the elderly and children will find it difficult to sleep well.
The cause of this situation may be because the bearings are damaged or dry, out of grease. Make the plastic pot brush against the engine, thereby emitting noise. You can fix it by adding grease to the fan or replacing a new set of bearings if it is damaged.
One of the most annoying things about being indoors is hearing the creaking, buzzing, or humming sound of a ceiling fan. So when we encounter this problem, we should find out the cause and fix it quickly instead of having to stop using the fan. Here are some of the most common causes of ceiling fan noises and how to fix them.
Check and clean the propellers
Dusty fan blades can cause the fan to shake because of an imbalance causing the ceiling fan to creak. Clean both sides of the fan blades with a slightly damp cloth or cloth. The top is usually dirtier than the bottom. Wipe off the wet stains on the fan blades afterwards because if the fan material is made of wood or plywood, it is easy to be damaged by water.
Make sure the blades are straight and not warped, damaged or mounted lower than the other blades. If the blades are not balanced, they can be reassembled. If the propeller is damaged, it must be replaced immediately with new blades purchased from the same manufacturer. Warped, damaged, or loose fan blades can cause the fan to wobble and put stress on the motor and fan hanger.
Oil the engine
After a long period of continuous use, the fan motor must operate regularly and require maintenance. When the ceiling fan hums and is no longer as cool as before, the most common cause is that the engine is running out of oil and needs to be oiled.
Tighten the propeller
Loose parts also make noise when the fan rotates. The first part to check is the propellers, where the propeller mounts to the bracket and where the bracket attaches to the motor. The propeller can be attached to the bracket with screws or keyholes that match pins or studs. The brackets are usually attached to the motor with screws or bolts. Tighten the screw or bolt with a screwdriver or wrench if loose.
Pay attention to the size of the screw to use the right screwdriver. This makes it easier to tighten and does not damage the screw head.
Tighten the light that comes with the fan
If the fan has a light attached, make sure all bulbs, lampshades, and any other fixings fit snugly. Most bulbs and lampshades are fastened with twist nails and can be tightened by hand. Do not use other tools as it is easy to over tighten the screws and break the bulb or lampshade.
If tightening the screws doesn’t make the light fixture parts tighter, you can add a thick rubber band around the mouth of the bulb or lampshade, and then re-tighten it with a screw. Fan manufacturers also sell rubber bands for this purpose.
Tighten the engine cover
Ceiling fans rattling and intermittent hum may be caused by the fan blade holder pulling the fan cover or motor housing. Usually you can fix this by loosening the screws of the engine cover, slightly adjusting the position of the engine cover, and re-tightening the screws. In addition, the propeller bracket must be securely attached and not allowed to rub against the engine cover.
How to stop and fix a noisy ceiling fan
Ceiling fan maintenance steps to avoid noise.
The first thing you need to do is simple but very important to you. Turn off the ceiling fan completely and wait until the blades stop.
Carefully check each ceiling fan to make sure that the propeller mounting screws are not loose, loose screws over long periods of use are one of the causes of annoying noise. If your ceiling fan has a decorative light, check to see if the fixture is loose.
Clean your ceiling fan. Because when used for a long time without regular cleaning, a layer of dirt will stick on the surface of the ceiling fan blades and over time these dust layers will accumulate more, causing an imbalance, creating pressure. unevenly onto the ball bearings inside the fan motor. This is the cause of the annoying hissing noise when the ceiling fan is operating. Remember to clean the ceiling fan on a monthly basis.
After checking and performing the above steps, check if the noisy hissing still occurs when the ceiling fan is operating. If the noisy hissing noise is still there, it is possible that the bearings inside the ceiling fan have dried out, if left for a long time, the fan motor will overheat and completely damage the motor. To save your dear ceiling fan, remove the fan motor and use engine oil to lubricate the bearings.
How to fix common ceiling fan errors
Cause of ceiling fan malfunction
According to experience, no matter which part is damaged, the ceiling fan also has 4 main causes of the problem.
It is possible that the power cord is loose or short-circuited. If the ceiling fan is not spinning, the first thing you should do is check the wiring. Check to see if the wire is shorted or loose.
Engines can fail due to design flaws or technical failures. You should contact the supplier to claim the warranty.
Many people think that the ceiling fan is not spinning because the fan is broken. But few people expect it to be the controller’s fault. If your ceiling fan uses manual control, make sure it has enough battery left to operate. The worst case scenario is that you may have to purchase the entire fan control system new.
The cause may be due to the wrong way of installing the fan or a technical error occurred during the installation process.
How to check when the ceiling fan has a problem
To check the ceiling fan when the ceiling fan is not working, follow these steps.
Please disconnect the power before opening the control panel. Use an electric tester to check for safety.
Remove the wire directly connected to the switch or switch of the ceiling fan. Then check and connect the ceiling fan directly to the power supply
If the fan runs normally when the power is turned on, the cause of the failure is the switch or switch of the fan. You need to replace it. If the fan is still not spinning, the problem may be with the wiring or the fan motor itself. You can double check the fan wiring.
Ceiling fan not receiving control
Ceiling fans are usually installed with a controller via a switch, fixed knob or remote control. If the fan still runs normally when using the switch but cannot be adjusted by the remote control.
Low battery control, out of battery
In this case, please replace the battery with a new one for the controller and use.
Control circuit failure
Check by pressing any key on the remote. If the indicator light is still on, the circuit is still working normally.
Ceiling fan with broken condenser
After cleaning the fan clean and lubricating it, it still rotates slowly? At this point, you need to replace a new capacitor.
Ceiling fan with damaged copper coil
Broken copper wire is also one of the factors that slow down the ceiling fan. If you do not have professional electrical knowledge, do not attempt to repair or replace the copper coil yourself.
If the indicator light does not come on, the control circuit is damaged and needs to be repaired or replaced. Broken circuit in the ceiling fan, you need to remove the fan to check the internal equipment.
Notes when using ceiling fans
- To ensure the safety of everyone in the family. As well as helping the ceiling fan to operate stably and with less damage, we need to pay attention to the following issues:
- Ceiling fans should be hung from the floor from 2.5 – 2.8 meters to maximize cooling capacity, air rotation and wind generation. Experts recommend not to hang the fan less than 2 meters from the floor because it can be dangerous to users. The minimum distance between two ceiling fans in a room is 3 meters.
- The fan should be installed in the center of the room.
- Use a ceiling fan with a moderate speed, do not turn on the fan too loud to save electricity. You should only turn on the fan at the middle or number 3 to be able to cool the whole room.
- Limit continuous fan use. If you must use the ceiling fan continuously during the day, turn it off for a period of 15 minutes and then turn it back on.
- Regular cleaning of ceiling fans is also important. Clean the fan parts, especially the ceiling fan, because it is easy to collect dust, which can cause rust.
- Regularly maintain, lubricate regularly to keep the fan running smoothly.
- When repairing and maintaining the fan, it is necessary to disconnect the power supply and use a protective suit.
F.A.Q: How to stop the noise of the ceiling fan?
What to do after maintenance, the ceiling fan is still running well but not cool?
Among the common errors, running but not cooling is the most common error. The cause of this situation may be because you set the fan’s swing mode. The second cause of this situation may be because your ceiling is too high, causing the wind from the fan to push down and not cool.
What to do when all parts are not damaged but the ceiling fan is not running?
The fan not running without failure is largely due to a loose plug. We often forget to notice the simplest things. In this case, simply plug the plug back into the power source. Make sure the plug is not loose and stuck to the socket.
However, if the socket or plug in your home has been used for too long and shows signs of being loose compared to the power source, you should replace the outlet with a new one. Thereby ensuring safety when using the fan as well as smooth operation.

This is a product that brings a breakthrough in the ceiling fan array with the advantage of being compact, does not take up installation space and is safe for users. With a smart design with vents, gently draw air from the bottom up and create flexible movement. With this type of fan, very few cases can cause noise. Unless your ceiling fan is hooked on something, the power
Does the propeller feature cause noise?
In fact, the number of blades and the width and distance of ceiling fan blades from each other is only a matter of aesthetics and finance.
Technically, 3-blade and 4-blade fans are easier to spin and require a smaller motor than 5-blade fans and are therefore generally cheaper. The blade length is tied to the CFM (Cubic Feet per Minute) of the air moved by the fan and the required CFM is related to the size of the room.
Hopefully the information provided in the above article will help you know how to check the ceiling fan when there is noise and when there are problems. You should also remember the notes to fix it effectively and reasonably.
