There are many reasons that ceiling fans can begin to shake. It can happen with new fans that have only recently been installed or years old fans. What are the possible causes, of the wobbly ceiling fan and what can you do to fix this?
A slight movement on the blades of your ceiling fan is normal when it’s in operation. The motion may be more intense if your fan operates at a higher speed. If you observe excessive wobbling, whether your fan is running at high or low speeds, it is advisable to look into the cause since excessive wobbling could pose an injury risk. Unbalanced fans are most often due to blades that are not balanced.
These are the problems that might cause the ceiling fans to sway:
- Loose blades
- Broken blades
- Blades that are warped
- Motor problems with the fan
In this article, we’ll examine these issues in-depth and then discuss ways to find the issues and solve the problem
What are the reason for wobbly ceiling fans?
1. Check For Loose Blades
Sometimes, a wobbly ceiling fan could be caused by loose screws on the blade, which stop them from spinning correctly. If the screws aren’t fixated, the blade could eventually break off. This is why it’s crucial to fix the problem immediately. The first step is to determine whether any fan’s blades are missing screws by reaching for an extension ladder and checking each blade. Take each blade in your hands and shift it slightly to see if there is any looseness.
You can also test for looseness of the blade by measuring the distance between your ceiling and the blades. A properly-installed ceiling fan should have blades of identical distance to the ceiling. If one or more blades are longer than the other, this could indicate that the blade isn’t well-anchored by the screws. If you find any looseness on the fan’s blades, make sure you fix the screws using the help of a screwdriver. If the screws around all the blades have been tightened, you’ll need to recheck the fan.
2. Check For Broken Blades
Another reason for wobbling fans is the imbalance of broken blades. This could cause the central load of the Motor to move in the opposite direction of the blade to be damaged. The problem is that broken blades can be difficult to spot.
To solve this issue, begin by looking at the blades as the fan is off. Check for signs of wear or cracks on the blade. It is possible to use a flashlight to inspect the blade’s top. If you notice cracks on any blade, the blade must be replaced to balance the fan. If all the blades are in good condition, proceed with the examination.
3. Verify Warped Blades
Blades that are bent or bent can create an imbalance in the ceiling fan. Most often, this is due to ceiling fans in rooms that have humid conditions or by using your ceiling fan regularly.
To identify if this is a problem, take all the blades from your fan, remove them, and place them together on flat surfaces. Then, look closely at the blades to determine whether they’re all laid flat on the floor. It is also helpful to lay the blades along the edge of the surface to observe any gaps between them and their surface. If there’s an opening, the blade is bent and must be replaced to restore balance to the fan.
4. Make sure you check the Motor
As time passes, ceiling fans can collect dust on their blades and within the motor housings. This accumulation may eventually strain the Motor (especially for older fans models). If the blades are extremely dirty, the fan’s center of gravity may be dislocated, creating an imbalance.
To fix this problem, you’ll have to clean all the fans’ blades and the exterior and interior of the housing for your Motor. It’s recommended to employ a dry microfiber cloth for cleaning the fan. You might need to take the Motor’s housing from the ceiling to remove it for cleaning. Once you have cleaned the blades and the motor housing, you can reassemble the Motor and then turn it up. If the fan is still wobbling, the next step is to test a balancing kit.

5. Use a balancing kit
The majority of ceiling fans include a balancing kit when you buy the fan. You can also buy the balancing kit separately. To get started with the kit, you must remove all of the small weights and the clip made of plastic from the packaging.
- Start by attaching the clip to the center of the single blade (be sure to remove the adhesive backing to ensure it doesn’t come off), and then turn around the Motor to determine whether it’s still in motion.
- Switch off the fan, and repeat the procedure for each blade till you’ve pinpointed the blade, which is the cause of the inconsistency.
- Once you’ve found the imbalanced blade, you can slide the clip across the entire length approximately 1/8 inch at a stretch to observe any improvements in balance.
- Once you’ve found the ideal spot where the clip will provide the best balance for the fan, grab one of the weights for balance and put it on top of the fan’s blade, just a few inches away from where the clip is.
- Then, apply the backing adhesive (or glue) to secure the weight and take the clip off the blade.
There are several reasons that ceiling fans can start to wobble. The most frequent causes are broken or warped fan blades, a buildup in dust that has accumulated on the surfaces of the blades or inside the motor housing of the fan. Here are some additional most common causes for ceiling fans that wobble.
6. A Ball Socket that is improperly seated.
Ceiling fans with down rods typically feature a ball socket on the top. It is located in the hanging bracket of the fan. When the fan is used for a long time, the ball socket will shift slightly towards the other side. If this occurs, the fan will begin to wobble.
7. Inadequate Ceiling Support
A lack of ceiling support is a frequent issue for DIY-installed fans. It is essential to make sure the electrical box in your ceiling is strong enough to support the ceiling fan’s weight and weight. If it isn’t the box isn’t sturdy enough, it could cause wobbling, but it also poses an extreme risk to your safety during operation.
8. Electrical Box Position
An electrical box that isn’t in line against the ceiling would nearly always cause the fan to wobble. This could be due to electrical boxes that were not properly installed, loose after a while, or are fitted with screws that are damaged or worn.
How much does a ceiling fan whirr?
It’s common for ceiling fans to experience a tiny motion of about 1/8 inch when operating at an extremely high speed. If it is wobbling more than this, it’s an indication that something is out of balance in the fan and must be checked whenever possible.
What is the reason for a ceiling fan’s sway?
Any number of factors, including an extensive accumulation of dust, unbalanced rotor blades or blade holders, dislocation of the rotors, and weak chandelier installation, can cause a ceiling fan to wobble. Restore the smooth running of your fan while they destroy the mechanical devices.
Why does the ceiling fan make a humming sound?
The Motor’s vibrations cause the majority of the noise from ceiling fans. The humming can become more intense when the fan is put on a higher level. Many modern-day fans are equipped with components that reduce the volume of humming that typically comes with ceiling fans. But, these components could fail. In that scenario, you might have to replace the component or find out the reason for the noise.
Common reasons for ceiling fans sounding humming
Unsecure Motor Housing
If you find that your fan is making the sound of humming at each speed, it may be caused by an engine housing with loose screws. To correct this issue, locate the motor housing on one of the sides, and give all of them a swift twitch with your screwdriver.
Electrical box with loose components
If you notice the fan produces an incredibly loud humming sound, particularly when operating at a fast speed, it might be because the electrical box isn’t securely fixed in place. It is crucial to address this problem quickly, as it could be a significant security risk. Examine the top of the fan, where the electrical box is connected to your Motor’s housing. Check for protruding, loose, or missing screws, and tighten them when needed.
Fan Blade Imbalance
If your fan has blades that are damaged or warped and are causing the fan to go out of balance, making an airy sound as it spins. To correct the imbalance, you’ll have to carefully examine all of the fan’s blades and then remove them to locate which blade is responsible for the imbalance. It is also possible to utilize a level and then place it over each blade to see whether the blade is the possibility of warping.
Unsecured Light Kit
Sometimes, the screws on the light kit could be loose, causing the light kit to begin shaking or vibrating. If you hear any light-humming sounds emanating from the fan, examine the screws in the lamp and ensure that they’re secured to the base.
There’s no need to tighten the screws as tightly as possible, as this may cause cracks in your light fixture (especially when it’s made from glass). However, make sure you tighten them to ensure that the light kit is securely held.
Will a wobbly ceiling fan fall?
A wobbly ceiling fan can be a cause for concern, as it may seem like it could fall at any moment. However, the likelihood of a wobbly fan falling is quite low. Ceiling fans are designed to withstand a certain amount of movement, and the wobbling is often just due to a minor imbalance. If the wobbling is severe, it could indicate a loose mounting bracket or a damaged blade, which could increase the risk of the fan falling. In such cases, it is recommended to turn off the fan and have it inspected by a professional to determine the cause of the problem.
A wobbly ceiling fan can be easily fixed by balancing the blades or tightening loose screws. If the fan is still wobbling after these adjustments, it may be time to replace it. It is important to address the issue of a wobbly fan as soon as possible, as it can be dangerous and lead to increased wear and tear on the motor and other components.
Wobbly ceiling fans are fixable by examining the motor housing and blades to find the cause of the issue. If you’ve inspected the fan but cannot pinpoint the cause of the problem, it is possible to speak with a ceiling fan expert in installation to inspect the problem.
