A wobbling ceiling fan may fall if the swing is too violent.
A ceiling fan needs to be properly balanced to prevent performance problems. A fan that is not evenly balanced across all of its blades may wobble back and forth on the ceiling. If the wobble becomes pronounced, the mounting rod may bend or break or the motor may fail. If general troubleshooting such as cleaning the blades and tightening down the screws holding the fan blades in pace does not solve your wobbling issue,you will need to rebalance the fan.
Instructions
1. Mark each blade of the fan with a piece of masking tape. Number each piece. The numbered pieces will help you keep track of which blades you have already balanced.
2. Bring one blade towards you and extend the measuring tape vertically. Measure the distance between the far edge of the fan and the ceiling. Measure each fan blade and see if any are higher or lower. Try bending the bracket holding the fan blade gently to move the blade to the right place. Run the fan to see if this has solved the issue.
3. Place the clip from a fan balancing kit, available from many hardware stores, on the blade you believe is wobbling. The clip slides on the end of the blade. Turn on the fan and observe. Move the clip closer to the motor if the fan continues to wobble. Continue moving the clip until the blades move smoothly.
4. Remove the clip from the blade and add a weight, included with your fan balancing kit, to the offending blade in its place. Secure the weight with a piece of tape. Test the unit. If the weight solves the problem, remove the adhesive back of the weight and place it on the top of the blade.
