7 Tips To Fix A
Noisy Ceiling Fan
|
A ceiling fan is an electrical appliance that most of us
take special care to choose. We all want a fan that
complements the interiors of the room and operates trouble
free for long. However, the problem begins when the fan
itself becomes the cause of sleepless nights by making ugly
noises that freak you out. As a matter of fact, a number of
you would have come across such situations when the
cacophony from the fan becomes a distraction. The good news
is that there is no reason to fret because fixing a noisy
fan is possible. While there may be a few fixes that you can
carry out yourself, there are others that would require an
expert’s intervention.
Here are some causes and solutions of a noisy fan:
1. Clicking noise due to wobble
Clicking noises from fans can mostly be attributed to
wobbling. Wobbling is the swaying of fan at high speeds. To
fix wobbling, try to attach the hanging bracket to the
structural member more firmly. If this does not resolve the
issue, check if the down rod is striking the ceiling canopy
or if the ceiling canopy is striking the ceiling. A good way
to prevent such contacts is to insert a piece of padding
between the parts.
2. Consistent mechanical grinding noise
Mechanical grinding noise may result from damaged bearings.
Most modern fans come fitted with bearings that last beyond
the life of the fan however should you come across such a
problem, make use of the warranty provided by the
manufacturer. In worst case, you may have to get the
bearings replaced which may actually cost more than the fan
itself.
3. Constant mechanical hum
Mechanical hum is caused when two elements of motor housing
vibrate together quickly. Most fan mechanics may confuse it
for electric hum because the speed of vibrations is very
huge. To eliminate this hum, the best way is to identify the
source and place padding between the vibrating parts.
4. Whooshing chopping noise like a helicopter
Whooshing noise like a chopper is due to disturbed
aerodynamics of the blades. This problem can only be fixed
by replacing the blades with better designed ones.
5. Constant electrical hum
Electrical hum is generated when the fan is being used with
a controller which is incompatible with it. While good
ceiling fan manufacturers provide controllers that are
compatible with the fan, having an incompatible controller
is not a rare occurrence. Try to avoid using solid state
controllers with ceiling fans. Ensure that the controller
that came with the fan is only installed with it. Electrical
humming sound is also a result of poor quality motor. Motor
quality is usually a cost cutting area in budget fans. This
cannot be fixed and the entire fan needs to be replaced in
case there is something wrong with the motor.
6. Intermittent electrical hum
Intermittent electrical hum may be caused due to interaction
of electrical devices nearby which are on the same
electrical phase as the fan. This issue may need an expert’s
intervention because the cause of interference may even be
the air conditioner or washing machine from your neighbour's
house. Ideal way to fix this problem is to switch to either
of the other two phases available.
7. Rubbing or ticking mechanical noise
An inconsistent mechanical sound may either be due to a
loose part or something that has gone out of place. Here is
something that you can do to identify the source and fix it:
· Foreign element: Check that there is no packing material
stuck inside.
· Rotor contact: Turn off the power and gently rotate the
blades. Carefully look around the fan to see if the rotor
and blades are making any contact with other stationary
parts. There may be a little contact between the parts which
can be separated by bending the non moving parts away from
the moving ones.
· Axial alignment: The fan may go out of alignment due to
worn out or poor manufacturing resulting in non concentric
rotation which may not be cost effective to fix. It is best
to contact the manufacturer in such a situation to avail
warranty if applicable.
- While these tips on fixing a noisy fan may solve most of
your problems with the fan, there may still be few that
require a technician to look into. As a matter of fact most
of the remedied mentioned above are best left to an expert
to avoid accidents and ensure genuine rectification of the
issue. |
