A couple of years ago I installed a ceiling fan in our bedroom (a cheapo one from B&Q). Every time it operates, there is a distinct "hum" coming from the unit. Very annoying if you are trying to get some decent kip! The fan is connected to the lighting circuit with a normal switch (not a dimmer switch).
It sounds like a mains hum from the motor, or possibly vibration from the motor. Was wondering if anyone can suggest something I can do to reduce or get rid of this noise. Or should I have not been so tight and purchased a decent fan in the first place :-)
