I have a new fan, and so do you.
The fan got increasingly noisy.
It was a breeze. The step-by-step instructions, especially the video, were exceptionally clear and helpful. When I actually did it, it felt like deja vu.
I wonder if the problem with the fan was the accumulation of dust...sort of like when ice forms asymmetrically on the wheels of your car , throwing off the balance and making the car shake at higher speeds...
The fan blades were caked with dust.
