Ceiling Fan Wobbling
Do you have a ceiling fan that wobbles every time you turn it on?
This is a common occurrence that can easily be fixed without having
to call in a specialist. One potential problem is that your ceiling
fan has loose screws. Considering that all ceiling fans have from
25 to 35 screws, it would be easy for some to become loose. Start by
tightening all of the screws used to hold the blade to the blade iron.
If that does not work, try securing the down rod to the fan motor.
Next, tighten the screws used to secure the down rod to the mounting
ball, the screws for the mounting bracket, and finally, the screws that
secure the ceiling box to the ceiling. This should resolve the problem
but if the wobbling continues, try tightening all the other screws.
Another possibility has to do with the blade sets. Ceiling fans have
matched sets of blades, each with only a one-gram difference. It is
possible that when the fan was installed, the blades were intermixed.
In fact, this problem happens all the time, especially if you are
installing several fans in the same room or even the same house. If
you believe this is the cause for your wobbling ceiling fan, remove the
blades and use a gram scale to weigh each blade. Then divide them into
sets so you have alternating weight, thus creating smooth movement.
If the two options mentioned did not work, you can try balancing your
ceiling fan. The first option would be to number each of your blades
and then remove two blades from the motor of the fan. Switch the
location of these two blades and see if the wobbling problem is fixed.
If the wobbling continues, replace the first two blades and then remove
the second two blades and switch those two. If this still does not fix
the wobbling problem, you can try a different balancing option.
The next balancing method consists of taking a lead weight or a nickel
and securing it with tape on top of one of the blades close to the tip.
You would then tape another about halfway between the motor and the tip
of the blade. Turn your ceiling fan on high speed and determine if the
wobble is better or worse. If you see no improvement, take the weight
off the blade and move it to the very end of the blade, again checking
the fan when on high speed. If you still see no improvement, try adding
more weight or moving the weight closer to the motor. When you finally
get the weight positioned so the wobbling problem is gone, secure the
weight permanently with glue.
Another problem that people deal with is the blades starting to warp.
For this problem, you should remove all the blades and then stack them
on top of one another, looking for any gaps. The blade or blades not
lying flat is the one warped. The best solution is to visit your local
home improvement store for blade replacements but be sure to take one
of your blades with you so a perfect match can be made.
