First, make sure dirt hasn’t accumulated on the fan causing things to loosen and start to shake. Clean your fan using our How to Clean Your Ceiling Fan guide. You also want to check your blades to ensure none of them are uneven or warped. If your blades have begun to warp you will want to replace them. You can find most blades on our ceiling fan blade accessories page. Make sure your new blades are made by the same manufacturer as your ceiling fan.
