How to fix a squeaking ceiling fan
Turn the ceiling fan off, and allow the blades to coast to a complete stop.
Grasp each blade and wiggle them to see if any of the fasteners (usually phillips type screws) are loose, and if so, tighten them.
It is unusual for loose blades to cause a squeak, but possible in some instances.
Also check that the light bulbs are securely in place; they can rattle around in their sockets. Look for excess dust accumulated on the blade surface, especially the top.
