Ceiling Fan Buzzing Noises
There is nothing more obnoxious than lying down to sleep, resting
comfortably under your ceiling fan, and then all of the sudden
experience a buzzing noise. If you are having this kind of trouble
with your ceiling fan, following are some recommendations for
correcting the problem. If for any reason you are running your fan
without blades or missing one or two blades, you could be hearing a
buzzing noise. While you would think that running a fan with the
blades on is common sense, you would be surprised.
If your ceiling fan is operated while using a dimmer switch, it is
possible that this is the cause of the buzzing. Another cause could
be due to your fan speed control, trying to control a fan with
numerous speeds. When shopping for a ceiling fan, make sure it has
a three-way or four-way wall control and nothing more. If you cannot
tell how much of the buzzing is coming from the fan itself, you can
remove the wall switch and supply live power directly to the fan.
This allows you to control the fan by the pull chain and determine if
the sound was reduced or eliminated altogether.
Many people choose ceiling fans that have a light fixture. As you run
your fan, over time it is possible that one of the glass covers for the
light has become loose. Check each of the light covers to make sure
none is clicking against the light bulb during operation. If you
believe this is your problem, wrap a rubber band around the glass lip
at the location where the screws are tightened.
If you only use your fan on occasion, allow your fan to run for 24 hours
straight before you try anything else. When fans are not used for any
length of time, the sound can be from the bearings that need to be
lubricated. All you need to do is run the fan, which will automatically
lubricate the bearings. New fans will often have a humming noise until
they have been operated for a few days, especially if your fan is
Promotional Grade. The reason is that this grade of fan has a small motor
and control standards that are lower in quality than other grades. In
other words, the fan is working harder, creating noise and possibly future
If you have tried all of these options but still have a buzzing or humming
ceiling fan, you need to get in touch with the store where the ceiling was
purchased or the manufacturer. On occasion, a fan will just be a lemon
that needs to be replaced. While this is not a common occurrence, it is
possible. In most cases, the store or manufacturer will be happy to offer
a replacement fan.
