Steps:

1. Turn off the main power to the fan. Use a ladder to reach the fan and clean the blades with a towel (figure A).

2. In this situation, Harrison traced the tapping noise to a light bulb that hit against its shade when the fan wobbled (figure B).

3. To remedy this, loosen the screws holding the shade and reposition it so the bulb doesn't tap against the shade. Tighten the screws once the shade is in the correct position (figure C).

4. Loosen the screws holding the fan to the ceiling bracket. Carefully lower the fan, you may need someone to hold it, and check to see if the mounting ball is correctly positioned in the fixture bottom. There is a groove in the ball that needs to line up with a tooth on the shaft. Line these up and tighten the screw holding the ball in position (figure D).

5. Before securing fan to the ceiling, make sure all wire connections are tight.

6. Turn power back on to check if problem is fixed.

7. If the fan still wobbles, try attaching a 3-gram clip-on weight to the trailing side of each fan blade in a trial-and-error process (figure E). After adding each weight, spin the fan by hand check for any improvement. If the weight is on the wrong blade the results are pretty obvious.

8. Once you eventually find the correct blade the wobble may not completely disappear. Clip on additional weights until the imbalance in corrected.

9. Once the wobble stops, add permanent weights by attaching 3-gram weights with sticky backing to the top of the corrected blade and remove the clip-on weights (figure F).

10. Test again for balance and enjoy the breeze.
