- Fan blade balancing kit
Balance the Ceiling Fan Blades
If your ceiling fan wobbles and makes more racket than an unbalanced washing machine load, read on; we've got the fix for you. Ceiling fan wobble is caused by imbalances in the fan blades or blade holders, misalignment of blades, excess dust accumulation or just loose blade holder mounting screws. Restore your fan to its smooth-running days of old before you wear down the moving parts. Plus: With ceiling fans, you get what you pay for. Read here.
Project step-by-step (4)
Make Sure the Blades are Straight
First, make sure all the blades are tightly screwed into the blade holder, and the blade holder is firmly screwed into the fan flywheel. Remove any dust or buildup from the fan blades with a household cleaner. Run the fan to check the wobble and to dry the fan blades. If the wobble persists, one of the blades may be out of alignment.
Check blade alignment with a yardstick by measuring the distance from the edge of any blade to the ceiling with a yardstick (most blades are angled, so be sure to measure on the same side of all the blades), and make a note of the distance. Hold the yardstick still and rotate the blades around to measure the other blades. If any blade is out of alignment, gently bend the blade holder up or down until the blade is in line with the others.
Slide on the Balancing Clip
Turn the fan on to see if it spins smoothly. If it still wobbles, pick up a blade balancing kit from a hardware store or home center. The balancing clip will balance the fan blades, eliminating the wobble.
Slide the balancing clip on the trailing edge of any blade, halfway between the holder and tip. Run the fan to check the wobble. Repeat with each blade, noting which one most reduced the wobble, then slide the clip in small increments away from the center of that blade. Move the clip, operate the fan, then move it again until you eliminate as much wobble as possible.
Set a Weight
Peel off the backing and stick the adhesive-backed balancing weight on the top center of the blade directly in line with the balancing clip. Add more weight if needed to get a smooth-running fan.
