Ceiling Fan Scraping
When you turn your ceiling fan on do you hear a scraping sound? If so,
various adjustments might fix the problem. To start with, the blade
iron motor screws might have worked themselves loose. To fix the
problem, you actually want to loosen the screws and then retighten them
while holding the blade irons to the motor. Keep in mind that you may
need some assistance for this option. Over time, these screws can become
loose. Additionally, cross-threaded screws that were probably used when
your ceiling fan was installed can create a scraping noise during operation,
which comes from the blade irons as they shift.
It is common for blades that are high gloss to make clicking type noises,
which is due to the screw heads as they cut into the lacquer. Another
thing to check is the blade, which could be rubbing on the blade iron.
To correct this problem, take a piece of felt and place it between the
blade and the screw head. While this may not take the problem away
completely, it should lessen the sound. You can also try spraying WD-40
on the surface of the blade at the location where the blade meets the arm.
If the problem persists, try buying non-gloss blades.
To get the scraping noise to stop, you may be required to take all of the
blades off and then check each screw while holding the blade up to the
blade iron. When the fan has been in operation for some time, the screws
can become loose. You should also check the ceiling mount. Remove the
canopy and examine the mounting bar to ensure the bar is tight to the
outlet box. If for any reason, the ceiling bracket should encounter the
sheetrock or plaster, the result is a scraping or clicking noise. You
also want to look at the down rod to make sure the connection at the motor
and by the ceiling is tight. If the down rod happens to shift while in
operation, a scraping sound can result. The pull chain on your ceiling
fan can be another culprit. If the motor is running rough or the fan is
wobbling, the chain can easily hit against the fan, causing noise.
High-quality ceiling fans are generally designed with a flywheel, which
is a rubber wheel that the fan blade arm is mounted to and then attached
to the motor shaft, held by only one screw. If your fan is older, it is
possible that the flywheel screw has come loose, which is causing the
flywheel to move away from the shaft, thus creating a scraping noise.
Another option is the housing clearance. Look at the space between the
outer fan housing and the inner fan motor to see if the motor is hitting
against any portion of the outer housing. Finally, as strange as it may
sound, if the breeze from the fan moves any object in the room, it could
be misconstrued as being a problem with the fan, instead of something in
