You buy a property and test the light fixtures as you move in. You put on the ceiling fan in the living room when suddenly this ceiling fan starts shaking like it is doing the twist. Your friend asks: “Why does your ceiling fan wobble?” I recently researched this topic, and I will help answer this question in this post.

Your ceiling fan wobbles when it is not installed correctly or when unbalanced blades cause excessive vibrations, bent blades, or even trapped dirt on the ceiling fan’s blades can cause it to wobble more. Ceiling fans are designed to have a bit of a wobble, but it should not be excessive.

There is nothing worse than switching on a ceiling fan to cool down in the summer months, and then the fan wobbles so much that it looks like it wants to vibrate out of the ceiling. I found out that there are many reasons why ceiling fans wobble excessively. I also found out what to do about it. Keep reading to find out more.

Why Does A Ceiling Fan Wobble? (The 4 Reasons)

Ceiling fans are designed to wobble a little bit, but they should not shake and wobble so much that it looks like they want to fall from the ceiling. Here are the reasons why ceiling fans wobble:

Using The Wrong Installation Box Can Cause Fan Wobble

You get two different types of installation boxes, one used to install light fittings and one that is used to install ceiling fans. Using the wrong installation box will lead to the ceiling fan becoming unstable and then wobbling more than it should. Ceiling fans have been known to tear out of these installation boxes because of them being unstable.

The light installation box is not designed to carry all the extra weight that a ceiling fan has, and that is why the correct installation box should always be used to install a ceiling fan.

Misalignment Of The Downrod Can Cause Fan Wobble

The downrod of a ceiling fan has a specific position that it needs to be in. if the downrod is not positioned correctly in the baseplate, then it will cause the fan to be unbalanced. When the fan is unbalanced, it will wobble.

The top part of the downrod has a groove that aligns with a pin on the baseplate. When the pin wears out, the downrod will move into the wrong position, and the ceiling fan will wobble. Always ensure that the downrod is lined up and that the pin is not worn out.

Bent Blade Irons Can Cause Fan Wobble

The Blade irons are the metal brackets that connect the fan blades to the motor housing; when these blade irons are bent at the wrong angle, the fan blades will also be at the wrong angle, which will cause the entire fan to wobble out of control. It is important to inspect the blade irons and make sure that they are all aligned correctly.

Some people modify parts of different brands of ceiling fans to work with another brand; unfortunately, it leads to misaligned blade irons. Make sure that the blade irons are suitable for the specific model of the ceiling fan to ensure that the ceiling fan does not wobble.

Problems With The Fan Blades Can Cause Fan Wobble

Many problems can pop up with the fan blades that in turn can lead to a ceiling fan wobbling; they are:

  • When people use unsuitable blades or modified blades on the wrong model of their ceiling fan, it will lead to the ceiling fan wobbling. Always use fan blades that are compatible and suited to the correct ceiling fan model.
  • When people use big fan blades on certain models of ceiling fans, it will cause the fan to be unbalanced and wobble. Always use the appropriate fan blade size for the size of the motor that the ceiling fan has.
  • When the fan blades are bent or warped, it will lead to a fan wobble. It is important to use fan blades that are straight and balanced to ensure that they work right and do not become unstable.
  • If the fan blades are dirty or have been painted many times, it will add uneven weight to the blades and cause the fan to wobble. It is a great idea to keep the fan blades clean and balanced for the best performance.

Tips To Prevent A Ceiling Fan Wobble

People always say that preventing a problem is better than looking for a cure, and it is also true in this case. Here are some tips from the experts to prevent a ceiling fan from wobbling.

  • Have your ceiling fans installed by experts because they will ensure that they use the correct installation boxes and that all the components are correctly aligned.
  • Keep your ceiling fans clean and clear dust and other debris from the fan blades. Use only compatible components together.
  • If you notice that a ceiling fan is starting to wobble more than normal, then have it serviced by a professional before it becomes worse.
  • Do not hang heavyweights on the chains of the ceiling fan switches because this can also cause misalignment of the downrod.
  • Do not allow children to play with anything while the fan is turning because the object may damage the fan blades if an object makes contact with the fan blade.
  • Do not hang clothing or laundry over the fan blades because they will become bent or warped.


My research has helped me understand why a ceiling fan starts to wobble. I hope that what I shared in this post is helpful to you in terms of what makes your ceiling fan wobble. We also saw that there are simple ways of identifying where the problem lies, and in using suitable components, you would be able to remedy most of the situations by yourself.

In cases where you cannot get rid of a fan wobble, it would be time to contact the experts or even replace the components or the entire ceiling fan.
