A ceiling fan wobble after installation is usually caused by something small being slightly off, not by the fan being “bad” right out of the box. The most common cause is an unbalanced blade. Even a tiny difference in blade pitch, a bent blade bracket, or one blade that sits a little higher or lower than the others can make the whole fan shake once it gets up to speed.
Another very common issue is the mounting box or downrod not being secure. If the electrical box is not rated for a fan, or if the fan bracket is not tightened firmly to a solid support, the fan can move enough to look like it is wobbling even when the blades themselves are fine. On a ceiling fan, there should be no play at the canopy, downrod, or motor housing. If the fan sways from the ceiling before the blades even get moving, the mounting is the first thing to check.
Blade installation also matters more than people expect. If one blade screw is slightly loose, or one blade arm is twisted, the fan will be out of balance. It helps to compare each blade from the side and make sure they all match in angle and height. Dust buildup can also contribute over time, especially if one blade collects more than the others, but that is less likely with a brand-new installation.
You should also look at the speed setting. Some fans wobble more at one specific speed, especially medium or high. That does not always mean something is wrong, but it can point to a balance issue that becomes more obvious at higher RPMs. If your fan came with a balancing kit, use it. Those small weights are meant to correct minor blade imbalance and often solve the problem quickly.
If the wobble started right after installation, I would check the basics in this order: make sure the ceiling box is fan-rated and firmly attached, confirm the mounting bracket is tight, inspect the downrod and pin, tighten every blade screw, and compare blade height and angle. Then run the fan at low speed and watch whether the wobble comes from the whole fixture or just the blades.
If you still cannot get it stable, the fan may have a warped blade, a bent blade iron, or an installation issue in the ceiling support. In that case, it is worth taking it down and rechecking the mounting rather than trying to live with the vibration. A wobbling fan is not just annoying; if the movement is strong enough, it can loosen parts over time.
