Why ceiling fan rotates slowly

That is why you should try to clean it regularly and oil its motor and bearings as necessary in order to prevent such a thing happen. However, if your ceiling fan has already started to slow down, you can fix it just by cleaning its bearing. The process is simple and quick. Remove the blades of the ceiling fan, if they are removable.

If not, just open the fan, and clean the bearing with a wet tissue then let it dry. If the dust has formed layers, try harder to remove it with a pointy tool. Do it slowly and carefully. Make sure the ceiling fan is off when you do it and then add oil.

If the fan still rotates in the same speed, that means the cleaning has been worthless. Therefore you will need change the bearings, which by the way do not cost that much. If the blades in your ceiling fan start to wobble after some time, that means one of the blades, or more, are unbalanced. The problem may also be that the blades are warped, bent or set at an angle different from the others. Or one of the blades may be more damaged, like broken.

Take care to replace the damaged blade, or set them at the right angle. In case you do not find a same blade like the others to replace the damaged one, replace all of the blades.

However, in case you buy a new ceiling fan, and its blades wobble, then do not try to fix it on your own, since it may have a manufacturing problem. Send it back to where you bought, and let them replace it with another. Handling this bad fan error, proceed to remove the cover, remove the control box and clean out any dirt. Then, add a few drops of lubricant oil or machine oil to the bearing. However, if you do not have experience, you should bring it to a shop or warranty center for repair.

Note: When removing the control box and seeing that the shaft and silver are damaged or worn, you should immediately bring the warranty center to repair or replace if necessary. After you have cleaned the fan clean, put oil into the bearing, but the fan is still in slow rotation, the possibility is that the fan has broken down the capacitor.

Because the capacitor is the part that directly affects the fan speed, so when the fan fails, the fan will not work or turn very slowly. In this case you need to buy capacitors with the same voltage index, capacitance with the old capacitor to replace, or bring the fan to repair if you have never done this before. If all the reasons for the slow fan rotation mentioned above are not correct, it is due to the coil thread being broken, the copper coil used for a long time is degraded.

With this error, you can bring the fan to the shop to help the repairman. Or you can buy a new coil that has already been wrapped in order to replace yourself.

But remember to see more instructions on the network to change the coil more accurately. One advice is that, if you are not a person with specialized knowledge in electricity, you should not arbitrarily repair the fan at home.

The component may be something like CBB You will also need to know the size of the capacitor. It is rated in size by what is known as microfarads. The symbol is ufd. Example: CBB61 1. This component has 3 wires attached to it.

A yellow and purple wire on one end,and a single red wire on the opposite end. Good luck I hope this helps. Rahul Aren. Solomon Thomas. This may be an often overlooked cause but it was the problem in my case.

I had a fan which has a mm sweep. A few months ago I sent it for rewinding and after it came back started running slower than before. The rewinding agency and the local electrician concluded and tried to convince me that factory original winding has an edge over a refurbished job and hence the lack of speed. After a lot of tinkering I compared it to the same fan installed in my bedroom and found out that the blade angles may be the culprit.

It so happened that while removing the fan and refitting it, the blades got twisted and two out of four actually drooped a bit lower than the recommended angle.

I spent 30 mins adjusting the angle an the position of the four blades using a reference point from the dangled a thread and marked where each blade should be touching the leading the trailing edge and to my surprise a small adjustment to the blades made a significant increase to the RPM. I should have noticed the fan actually getting hotter when ever I touched it in the past and I often disregarded it thinking of it as a result of extended run periods.
