Follow the steps below to determine the cause.
Ceiling fan slow speed problem.
Confirm the reverse switch is not in a neutral position.
The other possibility would be that the switch that controls the second position is somehow set to a slower speed perhaps it is set or broken on low.
Watch this video as this will help you troubleshoot and repair it under 10.
This is where not all the speeds are functioning as they should.
Essentially we ll use process of elimination to get to the root of the problem.
Unfortunately you cannot repair it your will have to replace it instead with a matching capacitor.
A faulty installation loose wires or shorted wires can cause the fan to lose speed.
Larger ceiling fans use oil contained in a reservoir that lubricates the bearing.
A blade that is.
5 the fan makes a humming noise.

Balancing for improved.

Checking for the proper lubrication.
I would guess that the second position is either mis wired or on an overloaded circuit.
Flip the switch several times to make sure it is the right.
In case the performance of your ceiling fan has lowered and its blades are rotating in a slower motion but it is for none of the reasons given above then it may have a problem with the split capacitor motor.
In this case replace the reverse switch.
A problem with the bearings a blade out of balance or a bad capacitor.
If you are using a remote or.
The first thing to try is to clean and lubricate the ball bearings.
