Electrical – Ceiling Fan is very slow after 2 years operation

ceiling-fanelectric motorelectrical

I have a ceiling fan which is working with very slow speed, even when the selector is set to the max (5 speed). What is the reason for that? Is the reason a damaged capacitor or any other reason?

I just removed the speed controller and connected to the direct power line. After that, the issue remains. I have basic electronic and electrical knowledge but I couldn't find the reason. I am guessing that the capacitor is bad. Please help.

Does your fan have sealed bearings or ball bearings ? They can get dirty and cause mechanical drag. there may be other rotational loses coming into play. try a dry lubricant from a bike store if there are parts that need it. there could be a issue with the rotor or stator effecting the flux transfer to allow the motor to spin

What happens if the fan motor is plugged into the wall? does it run full speed? if it does there may be a fault in the electronics of the controller board

hope the idea help
