Answer / happy

as we know that our ceiling fans are 1-phase operated. so we have that capacitor for splitting another phase in order to provide enough torque for self starting. So due to that phase splitting, capacitor and coil sounds due to little riple factor... so you need to change the capacitor(condenser) or avoid operating fan on invertor's supply...

Answer / pillay

1)check the bearings
2) something is rubbing on to each other
3) there is a snake in the fan
