Why is your Ceiling Fan Humming?
As you are probably aware, most electrical
items contain some noise; this, of course,
includes ceiling fans. The noise of a ceiling
fan should be a gentle whir sound of air that is
circulating rather than a humming sound.
There are different characteristics of a ceiling
fan that may cause it to hum, or make other
irritating noises.
A humming sound on a ceiling fan is usually the
consequence of bad engineering or poor
manufacturing. The manufacturers may have used
cheap, non-precision ball bearings to produce
their ceiling fans in order to save on
production costs. Some fans may not have been
constructed with proper dampening elements
between metal parts which could also cause a
humming sound.
The humming noises could also be caused by the
type of electrical control system that was
installed within the fan during its production.
A capacitor control system is contained in the
highest quality ceiling fans; this system allows
the fan to be set at different speeds such as
high, medium or low. The variable fan speed
controls have a solid state control system that
enables the ceiling fan to operate from speed
ranges of low to high. However, the solid state
control is not as efficient or as durable as the
capacitor electronics, nor are the two controls
compatible or interchangeable. A cause of a
humming or a buzzing sound could be that a solid
state control was used on a capacitor ceiling
fan.
It is recommended that most ceiling fans be
installed with a more efficient capacitor
control to prevent noises such as humming or
buzzing.
