Standing fans, wall fans or other fans such as ceiling fans, misting fans, . are indispensable "friends" of every family on hot summer days. But have you ever felt that there were times when the fan turned slowly despite the largest number? If yes, join the Network Administrator to find out the cause and how to fix the weak rotary fan right now!

  3. Notes when using misting fans

1. The fan has a lot of dust

Using a fan for a long time but not cleaning it, cleaning it regularly will cause the fan to stick a lot of dirt, limiting the fan speed, the air flow is weaker and no longer makes you feel comfortable when using.

How to fix:

To protect the engine as well as to help the fan run smoothly and bring in more fresh air, you should periodically clean the fan every 1-2 months. Removing - installing the fan is very simple, you can remove the propeller, fan cage yourself, even the motor control box and use a soft cloth to wipe off all dirt. If you are not confident, refer to some fan maintenance and cleaning tips for how to do it correctly.

2. Fans are banned from oil and silver engines

A seemingly heavier cause causes the fan to be weak or make noise when it is turned because your fan is dehydrated, increasing friction makes the fan spin slowly or damage the silver engine. To "catch" more accurately, check by disconnecting the power and removing the fan cage. Next, try rotating the fan by hand, if you see the fan rotating but it is blocked and only turns a bit and then stop, then it is definitely a fan with oil and silver damage.

How to fix:

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.

3. Fan capacitor is broken

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.

How to fix:

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.

4. Broken copper coil

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.

How to fix:

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.

Thus, we have given some reasons and how to fix weak rotary fans to help you use electric fans better. In case you have tried all the above methods but the fan speed is still "slow like a turtle", your fan is probably too "old". At this point, you should consider buying a new fan for more efficient and safe use!
