Ceiling fan lost strength got very weak solution would be to call an electrician technician and check what the defect because this defect may be just a capacitance or even the motor itself so this should do all the tests.
How to Fix a Ceiling Fan
It would be as if you were stuck in the middle of the Sahara desert if the ceiling fan suddenly stopped working. It’s the only thing that cools the room at the bottom and keeps the air circulating inside an unventilated area. It’s still not the time to call a technician, though. Maybe you can fix your ceiling fan. Who knows, you might find a handyman on you and that would save you a little money to fix.
Here are the things you should do when your fan does not seem to work.
Check all fan controls
These include the switch and the remote control of the fan. Make sure that the switch can be turned on smoothly as before. If you feel that something has changed then there must be a problem with the key. The problem like this is better to rely on professionals if you do not know how to repair a broken switch. Check the remote control too. If that does not work, maybe the batteries are already dying. Replace and recheck the remote control. If nothing happens, open the remote control may be necessary.
Check the connection
This is most likely the problem if both the light and the fan does not work properly. Be sure to turn off the fan or better yet, turn the power switch on the house before checking the switch. Simply reconnect the loose wires and cover with electrical tape.
Check the black wire
This thing turns the engine fan on. It must also be connected to ensure sufficient power to the fan.
Testing the blades
Try turning on the blades if they can flip smoothly. If they can not, maybe they need lubrication or maybe a little ‘dirt’ are piled around the blade.
What to do if the fan works but it happens very slowly? Try to control the blades as shown above. If nothing happens, try the following possible solutions:
Check the capacitor.
Some ceiling fans have permanent split capacitor motor. As this engine grows, they also make the fan slow down. Check that the capacitor is too old. Consider your need for replacement.
Check for oscillations
Is there some strange vibration? If so, this may have been caused by a slower motor, which is slower running of the blades due to the unbalanced blade ratio. Try to balance the blade, so it will be prevented from swinging.
There are even a number of other ceiling fan problems that need fixing. For example, if you hear mechanical noise while the fan is running, then it should be a problem with the engine or anything mechanical. Repairing these problems usually require the opening of the fan motor, which should be reliable for professionals, unless you can not take the risk.
Meanwhile, other problems only need proper control of the speed of the fan or the removal of dirt trapped in the fan. It is best to look more closely at the ceiling fan to see what is wrong before doing something or calling a professional. If the problem seems to be something you can not cope with then you’d better seek help. It will be more expensive to replace a ceiling fan broke due to defective repair than to pay a professional to fix your old fan.
