Why does my fan make a tapping noise?
A ceiling fan making clicking noise may be caused by blades that aren’t firmly attached to the fan assembly. This problem is easy to correct and generally only requires a set of screwdrivers. Step 3: Use a screwdriver to tighten the screws. Avoid tightening screws too much, as this may cause damage.
What kind of noise does a fan make?
There is also an outward pulse of air as the leading edge of each blade pushes forward cutting the air. The trailing eddies produce a broad spectrum of random noise, modulated by the fan blade frequency. The outward pulses, of course, occur at the blade frequency, with harmonics.
Which is part of the fan blade actually does the noise generation?
BFI is some sort of correction relating to blade frequency, usually a single digit number of dB. Finally C N corrects for inefficient fans. Zero for a “perfect” fan, to about 12dB for a fan that’ only 40% efficient. Efficiency here is “hydraulic efficiency” based on air flow, pressure, and motor power in horsepower (HP):
Why are the blades on my Ceiling Fan so noisy?
Dirty blades can become unbalanced, making them noisy over time. Here’s how to quickly clean your fan blades and housing: Step 1: Use a step stool or ladder to access the highest point of your ceiling fan.
What should I do if I hear an engine noise?
Whatever noise you are hearing, it’s vital to have it diagnosed immediately. Otherwise, the problem could lead to irreversible engine damage. Luckily it is often enough with smaller repairs when you experience any engine noise. If the engine becomes damaged beyond repair, you are going to need a replacement.

Why does my fan make a ticking noise when it rotates?
When dust build up on top the blades gets thick, it can throw off the balance. This makes something rub when it gets spinning fast. You may also notice a slight wobble when the fan is running. I know this can happen. This happened to me. It only made noise on high speed. After cleaning the blades, the wobble and ticking noise stopped.
