Is there any unusual noise such as knocking or ticking?
Are the blade holding screws or screws for the suspended parts loose?
1. Make sure the bracing structure is sound and firm. Even slightly loose fixings may create
knocking or ticking that will reverberate down through the fan. Upper canopy should not be in
contact with the ceiling surface. It is suggested to leave an even 1mm to 4mm gap between
the ceiling and the edge of the upper canopy.
2. Irregular humming noise may be caused by electrical interference from another appliance, or
ripple control signals being introduced by the electricity provider.
Night Noise
This is the biggest cause for service calls, which are outside the manufacturers warranty. If a fan has
a fault, it will always be noticeable. Naturally when everything is quiet at night, you will be more
inclined to hear small noises, which may not be noticeable other times. Even slight power
fluctuations and/or mains frequency control signals superimposed in your electricity supply for off
peak hot water control may cause a change in the fan motor noise. This is normal.
Warning:
If at any stage the fan develops excessive wobbling or unusual oscillating movement Is
observed, immediately stop using the ceiling fan and contact the
manufacturer , Its service agent or suitably qualified persons .
Fan Light:
Except for an actual fault in manufacturing, which is extremely rare, noises and
vibrations are often more accentuated when a fan light is fitted. For instance, a fan light glass
that has not been tightened or worked loose can cause a rattle.
Frequent care and maintenance will reduce this.
