Unfortunately, many ceiling fans have been installed on electrical boxes designed for light fixtures, not the fan -rated boxes required by code. This means the fan is attached to a box that isn’t designed for the additional load.

To be certain how the fan is mounted, you may ultimately need to make a trip to the attic. A fan -rated box is usually so labeled, and you’ll usually see hexagonal heads of lag bolts attaching it to a wood brace, or U-bolts attaching it to a metal brace.

If you can’t tighten it, or if the box is the wrong type, install an adjustable fan brace (available at home centers). Make sure the tooth on the fan support bracket is resting in the slot on the ball joint.

If none of the fixes above solve the problem, try balancing the blades. Balancing kits are available at lighting stores, but you can also use coins.

Start by taping a dime to the middle of a single blade and turning the fan on high. Repeat this test for each blade until you find the one where the wobble starts to lessen.

If the ball socket groove isn't seated into the notch of the hanging bracket a ceiling fan will almost always wobble. Many times the wobble will be present on all speeds and no matter how much you try to balance the fan nothing will work until these two parts are properly aligned and seated.

To start with, check all screws that hold the blades to the motor and make sure they are very tight. There is a safety pin that keeps the down rod from ever coming detached from the fan, but set screws are there to lock it in place securely.

I find many cases where an installer got into a hurry and forgot to tighten the one or two set screws in this area. You will also find a set screw at the top of the down rod where the half ball socket attaches to it.

In order to make sure this set screw is tight, you will need to lower the canopy away from the ceiling. Hopefully you don't have a Hunter or newer Casablanca ceiling fan, as in many cases the canopy doubles as part of the hanging bracket.

High-end brands such as Modern Forms, Mink Are, Gulf Coast, Proposal, and Animation all use a separate hanging bracket to support the weight of their ceiling fan, and the canopy is only a shell that covers the main part of the hanging bracket, and not actually holding the fan to the ceiling. This allows the canopy to be independently lowered from what is actually holding the fan so that you can easily get to the set screw securing the ball socket to the down rod.

Any looseness, in any of the screws mentioned above, can be a major cause of ceiling fan wobble. Therefore, checking all of these and tightening them may solve wobbling issues and help you to enjoy your ceiling fan even more.

This is because each blade iron is pitched to an exact degree from the manufacturer, and if assembling the entire fan at the floor level and then trying to attach it to the ceiling there is a good chance a blade iron could become slightly bent, thus causing the fan to wobble. To check to see if this is the culprit of your shaking fan issue, you will need to do what is known as blade tracking.

You can attempt to apply pressure to bend them back in line with the others, but it is very hard to get them exact. Your best bet to fix a wobbling ceiling fan that is caused by bent blade arms is to order a matched replacement set of irons.

Even though some carbon composite electrical boxes may claim to be rated for ceiling fans, they are still not as sturdy as the metal ones. It will be a pain in the butt, but you may have to take the fans down and change over to the metal boxes to fix the issue.

Screw them to each other, this way your electrical box will have plenty of stability above it, so then once it is tightened down there will be no give (or play) in it. A ceiling fan bracing kit usually works well also, but I am a firm believer that the 2×4 method mentioned above will be your best bet.

Following these suggestions before attaching any fan to the ceiling will ensure that a wobbly ceiling fan isn't being caused by inadequate support. Before installing a ceiling fan, you'll want to make sure the bottom of the electrical box is completely flush with the ceiling on all sides.

This way the fan's hanging bracket tightens securely to the electrical box, not the ceiling material, thus providing the proper support needed. Many times an electrician may have supported the box the proper way, but may fail to get it perfectly flush with the ceiling.

If one side of the box is flush, yet the other side is recessed behind the ceiling 1/8” of an inch or so, this will cause the bracket to tighten against a ceiling surface that is usually Sheetrock, and not to the solid foundation of the electrical outlet box. The Sheetrock may eventually crumble away, causing then the hanging bracket to become much looser and the wobble will become much worse.

That said, you can try to balance the fan (outlined in Reason 6) but it may only provide a temporary fix and several months, or a year or two later you may be right back to the same issue of your ceiling fan not running smoothly again. Another quick fix, that may be more permanent, but still not as ideal as making sure the electrical box is installed properly in the beginning, is to take the fan, and it's hanging bracket down from the ceiling.

Install washers between the electrical box and the hanging bracket, filling up the of the gap between the bottom of the ceiling and the electrical box, so that the ceiling fan hanging bracket can tighten up solidly without pulling through the Sheetrock. NOTE: Before removing the fan from the ceiling to fix any issue, make sure you detach the blades from the motor.

Taking a fan down completely assembled risk bending a blade holder. Unfortunately, this matching of blades to exact weight within a set is not usually the case with inexpensive ceiling fans.

After attaching the clip, turn your ceiling fan on high speed and see if you got lucky on your first try, and the wobble is gone. However, if none of the positions fix the wobble, you will need to stick one of the balancing weights on top of the blade at the position that makes it the best, and then reposition the clip onto the center of one of the fan blades again and start the process from the beginning.

I personally hate dealing with it, and that's why I never purchase cheaper quality fans that I know may have issues like this. If none of these are the reason behind your fan wobble, and you find your issue was caused by something not mentioned here, please feel free to comment.

Wobbling and vibrating place significant stress on many parts of the fan and will ultimately shorten its life. In most cases a wobbly fan can be traced to one of these sources: the fan isn’t securely fastened to the ceiling, the blades are unbalanced, the blades are warped, or another part is loose on the motor or pole assemblies.

Before you do anything else, make sure to clean the fan blades and the motor housing with a dry lint cloth. An easy way to determine this is by standing on a stepladder and grasping the fan body while trying to shake it.

For the fan to be stable it has to be installed on a correct ceiling mount: that is 2×4 grins along with lag screws. You can normally undo the bracket frame and can have a look at underneath of the fan in what way it is connected.

You can examine the sticker present on the fan’s electrical package and stare at the skulls of hex bolts which are attached to the wood or metal brace. Assess the coat-hanger ball and ensure that it is placed firmly in its furrow.

Plaid with the button covers to ensure that it is tightly and steadily attached to the light equipment. After a long duration of time, the fan blades start to slightly fall off, mainly if it presents in the places with high dampness or some alterations in temperature.

This is the main reason for the fan’s unsteadiness and results in producing sound. With the tape check the perpendicular space between the ceilings and to the civic amenity point of the fan blade.

If whole dimensions are not similar then regulate the blades by rotating the mounting screws tightly so that they hold properly to the motor housing. Blades with too lightweight or too short will not move the air efficiently.

Balancing kit comes with a plastic clip and nearly five small weights, with adhesive backing to make them easily attached to fan blades. Attach the plastic clip to one blade about half of its length, and turn on the fan to check whether the instability has improved or not.
