Cleaning the fans periodically increases the life of the fans
In the present day as the fan price in india has come down considerably, nobody go for rewinding of the motor, instead they buy a new fan.
Once in a while some minor problems may arise and often it will be settled by changing the capacitor or the like. In rare cases the motor winding may get burned up due to heavy load or similar reasons. Rewinding the motor was done in the olden days as the fan price was higher in those days. Only a screw driver, some detergent and dry cloth are needed for cleaning the fan. Before you start the cleaning process; unplug the fan from the main supply line. After this one can wipe of the dust from the outer surface of the fan. After wiping out the dust one can start disassembling it. At first remove the grill by unscrewing the screws used for keeping them together. Some fans have only clips instead of screws and this makes things easier. After removing the grill action, to remove the blades can be started.
At this stage one can clear the grill using detergent. You have to be very careful while doing so as no electrical parts are expected to get wet during this cleaning process. Now use towel and dry the washed parts. Now, you can reassemble the fan in the reverse order. Tighten the screws and plug in the switch. Your fan should now work perfectly.
If you still hear some clicking sound it can be due to dust or dirt inside the fan. In that case repeat what you have already done once more. Unplug the fan, remove the grill, remove the blades, and this time you can apply vacuum cleaning for the shaft. After this inspect the gears and make sure that everything is ok. If gears are ok you can put everything together and complete the repairing task. Now no clicking sounds will be left. By doing maintenance work like this one can escape from the burden of buying new fans as the fan price in indiais considerably high.
