When your ceiling fan needs lubrication, you are most likely going to hear squeaky sounds, or grinding sounds from your fan’s motor.

Running your fan without oil; the bearings will cause the fan to spin with difficulty. It won’t speed up and the squeaky and grinding bearing noise it makes will only get worse with time.

How to Fix This

Follow the steps below to get your motor well lubricated:

  • Turn off the power to the fan from the panel
  • Get your screwdriver ready to disassemble the fan
  • Take the fan down. When doing so, be careful to avoid causing any damage to the wiring
  • Remove the fan blades and also the lighting if your fan has one
  • Take out the motor from the fan’s interior
  • Locate the motor bearings and apply lubricating oil. 2 to 3 drops of general lubricating oil would do just fine
  • Rotate the bearings while applying lubrication to ensure it gets to every corner of the bearings
  • Reassemble your fan and mount it back once done
  • Mount the fan back with the power still off for safety

2. Bent and Unbalanced Blades

When your fan has bent blades, or one is unbalanced, it comes with noise once the fan starts spinning.
