Ceiling fans have to work a lot, after a long time, the dirt will thicken and make the fan heavier, starting to make an annoying noise when operating. Fortunately, these squeaks can be rectified with regular cleaning and maintenance. Cleaning the fan blades and re-tightening loose screws will usually fix the fan noise problem, but you can also fix some other more complicated problems if these don’t work.
Steps
Cleaning and maintenance of ceiling fans

Turn off and wait for the fan to stop completely before servicing. Never try to clean or repair the fan while it is spinning to avoid injuring yourself. You should also let the fan stop slowly, don’t hold the wing to make it stop quickly. Holding or pulling on the propellers can cause them to warp and cause other problems. [1] X Research Source
- If you just clean and perform routine maintenance, you don’t need to turn off the power.

Wipe the fan blades with a dry soft cloth. You will need to use a ladder to reach the ceiling fan. First, clean both the top and bottom of the fan blades with a soft cloth, then spray the blades with multi-purpose cleaner and gently wipe them with a new fine cloth or paper towel. [2] X Research Source
- The weight of dirt can really make the fan creak! That’s why cleaning is the first step you need to take when servicing your ceiling fan.
- You need to be gentle when cleaning the fan blades to avoid putting weight on them.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/9b/Fix-a-Squeaking-Ceiling-Fan-Step-3-Version-4.jpg/v4-728px-Fix- a-Squeaking-Ceiling-Fan-Step-3-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/9b/Fix-a-Squeaking-Ceiling- Fan-Step-3-Version-4.jpg/v4-728px-Fix-a-Squeaking-Ceiling-Fan-Step-3-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Shake the propeller and tighten the loose blades. Once firmly on the ladder, try shaking each propeller to see if they need tightening. If the propellers are tight, they won’t move. If you can swing them side to side or up and down, use a Phillips screwdriver to tighten the screws until the blades stop shaking. [3] X Research Sources
- Loose propellers can make strange sounds, so you should check them every 6 months to see if there are any screws that need tightening.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/82/Fix-a-Squeaking-Ceiling-Fan-Step-4-Version-4.jpg/v4-728px-Fix- a-Squeaking-Ceiling-Fan-Step-4-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/82/Fix-a-Squeaking-Ceiling- Fan-Step-4-Version-4.jpg/v4-728px-Fix-a-Squeaking-Ceiling-Fan-Step-4-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Check the bulbs to make sure they are not loose. If your ceiling fan has a light bulb, you’ll need to check each bulb one by one to make sure the lampholders are secure. If the fan has been running for quite some time before you turn it off for service, you should try touching the bulbs lightly first to make sure they don’t overheat. [4] X Research Sources
- Loose bulbs can cause the fan to creak due to the lamp holder wobbling in the fan base.
- You can also take this opportunity to replace burnt out bulbs.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/53/Fix-a-Squeaking-Ceiling-Fan-Step-5-Version-4.jpg/v4-728px-Fix- a-Squeaking-Ceiling-Fan-Step-5-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/53/Fix-a-Squeaking-Ceiling- Fan-Step-5-Version-4.jpg/v4-728px-Fix-a-Squeaking-Ceiling-Fan-Step-5-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Check the lantern if there is one. Some ceiling fans have a lantern that encloses the entire bulb or bulb set. Check to see if this lantern is securely fastened. If necessary, use a Phillips screwdriver to tighten the lantern screws, which are the screws you need to remove when you change the bulb. [5] X Research Sources
- Cracked lanterns can also cause rattles. If you find a crack in the lantern, you should consider replacing it with a new one.

Check the screw that attaches the fan to the fan mount. The fan mount is the part that attaches to the ceiling and connects the wires to the fan body. Check the fan for any loose screws. If so, use a Phillips screwdriver to tighten them. [6] X Research Sources
- The screws that attach the fan body to the fan housing can start to loosen over time and cause the fan to rattle.
- Sometimes the screws can break. Replace the screws if they are lost or damaged.

Run it and see if the fan is still buzzing. If the fan has several different speeds, turn them on one at a time for a few minutes. If the squeal is gone, great! You have successfully serviced the fan. If the fan is still rattling, it could be due to something more complex. [7] X Research Sources
- You can try to fix this complicated problem or call a mechanic to fix it.
Fix complex problems
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/0f/Fix-a-Squeaking-Ceiling-Fan-Step-8-Version-4.jpg/v4-728px-Fix- a-Squeaking-Ceiling-Fan-Step-8-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/0f/Fix-a-Squeaking-Ceiling- Fan-Step-8-Version-4.jpg/v4-728px-Fix-a-Squeaking-Ceiling-Fan-Step-8-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Disconnect power from the circuit breaker if repairing near power lines. Before performing any repairs near the fan’s wiring, you need to have a circuit breaker that completely cuts off the power to the room. When you return to the room, test the fan to make sure the power is off. [8] X Research Sources
- If you don’t need to repair the bottom of the fan (e.g. just adjust the blades for balance), you don’t need to turn off the power.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/0a/Fix-a-Squeaking-Ceiling-Fan-Step-9-Version-2.jpg/v4-728px-Fix- a-Squeaking-Ceiling-Fan-Step-9-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/0a/Fix-a-Squeaking-Ceiling- Fan-Step-9-Version-2.jpg/v4-728px-Fix-a-Squeaking-Ceiling-Fan-Step-9-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use an equalizer to rebalance the propeller. You put the balance clamp on the middle part, equidistant from the beginning and the end of the wing, turn on the fan to see if the noise is still emitted. Do this with each wing in turn. Once you’ve found the point to balance, peel off a weight sticker and stick it on the wing in a horizontal position with the leveling clamp, then remove the clamp. [9] X Research Source
- You can buy an equalizer at electrical stores for less than 500,000 VND.
- The impeller leveling lever can eliminate fan squeaks if they come from wobbling or warping blades.
- You can find tutorials online to learn how to use the equalizer.

Oil the bearings to lubricate the engine. You need to disassemble the whole fan (pay attention to turn off the power), and take out the motor in the fan. Locate the bearings, apply about 2-3 drops of lubricating oil. You rotate the engine to distribute the oil evenly, then reinstall the fan, turn on the power and test to see if the fan is still noisy. [10] X Research Source
- Bearings are the parts that help the fan rotate. If they are dry or rusty, they can make strange noises.

Contact a fan repairman if you cannot fix the fan noise. If normal cleaning, maintenance, and some more complex checks don’t fix the rattling fan, the cause may lie deeper in the structure of the fan’s components. You should go online to read reviews of some repair facilities, and remember to pay attention to the information “licensed, committed, warranted”. [11] X Research Source
- Contact a number of electric fan repair places to find out the cost of repair, and compare with the cost of replacing a new fan to help you decide which option to choose.
- When hiring a repairman, you should ask how they guarantee or cover you. If the fan is noisy again after a few weeks of repair, will they come to check it again for free?
Advice
- When you can’t fix the fan, don’t hesitate to call a repairman, that’s their job!
Warning
- Be careful when using ladders or high chairs.
- Disconnect the power supply before removing the fan, especially with corded fans as voltage may remain even when the fan is turned off.
- Never adjust or manipulate a spinning ceiling fan.
