What are the common electric fan problems and how to take care of them? Let’s find the answer only at dimulti.id!

You might wonder why your electric fans stalled and not working properly, and why your fan’s blade is turning but it turns so slowly?

Well, there’s indeed some problem with your electric fan, and in today’s article dimulti will give you the common electrical problems and how to fix it. Let’s dive in!

Common Electric Fan Problems

Before we get to the main topic, I guess it’s a good idea to first know the parts of the electric fan to make it easier for you to repair and by recognizing the components of each part of the fan it will be possible to find out the damage that occurs in the fan.

The fan components themselves consist of electrical cables and plugs, fan motors, blades, capacitors, gear boxes, and bearings. Now that you know the fan components, let’s review what damage often occurs to the fan.

1. The Fan’s Blade Won’t Rotating or Rotating Slowly Followed by Humming Noise

This problem occurs because the bushing or bearing inside the fan is damaged. Bearings that have been damaged usually can no longer be repaired because the bearing cover lock has broken so we have to replace it with a new one.

The damaged bearing is usually black- burning-like in color. The fan bushing serves to place the fan axle. If this is not positioned properly, it is certain that the fan will not be able to rotate properly or even cannot rotate at all.

Damage that occurs to the bushing is usually caused by wear. In addition, it is also due to violent vibrations.

Here’s how to replace the fan bushing:

Open all covers or fan covers.
Remove the four bolts at the back (near the coil).
Remove the damaged bushing and replace it with a new one.
When finished, reinstall the four bolts and install the blade.
Test run the fan first.
If it’s ok, put everything back together.

2. Completely Dead

fans with total shutdown damage are characterized by when the ON button is pressed, the fan blades do not rotate and there is no vibration at all in the fan motor (as if there is no incoming electric current).

For how to solve it, first check the fuse, and also if the power cable may be broken. Also check the speed button and check the timer button if there’s any.

If the four elements are in good condition then for the second step, check the fan motor (which you can check using a multimeter) . Maybe the windings are broken or even burned for the worst case scenario.

3. The Fan Blade Won’t Rotating Without Humming Noise

In this case, it is certain that the fuse inside the fan has broken. A fuse is a safety component in electronic equipment.

If applied to a fan, the fuse functions as a safety from excessive heat so that it will protect the coil from burning.

The fuse will disconnect itself if the coil condition is too hot. To make sure the fuse is damaged or not can be done by measuring using a multimeter.

4. The Blade is Rotating but Slowly

Damage like this is characterized by, when the button is turned ON the motor / dynamo fan will vibrate like a hum, the blade rotates slowly or even does not rotate at all. the following solutions for damage like this.

First make sure that the axle is not dragging / stuck (if it is stuck it must be cleaned first), second make sure that between the axle and the bearing is not rocking / loose.

After the two steps are okay but the fan doesn’t want to spin either, we take the next step which is to replace the capacitor (usually the size of 1 mf, 1.5 mf and so on).

5. The Speed Controller is Broken

For example, your fan has 3 speed buttons, but speed no. 3 is off, the first possibility is damage to the speed button, the second possibility is damage to the fan motor.

6. The Fan Won’t Oscillating

For damage like this, check the back of the fan motor / dynamo, usually the damage is due to too prolonged use that makes the locking bolt between the dynamo and the gear loose.

For fans that use a separate motor, check the on/off switch and there is a possibility that the driving motor is damaged.

So there you have it! The common electric fan problems!

Did you know that the electric fan is one of the many products that are mandatory to be certified by the SNI certification in Indonesia?

This is because the risk of an electric fan might be concerning for the Indonesian consumers, as the fan that is not properly manufactured can cause a failure and can even be dangerous for its users.

The electric fan that is about to be distributed in Indonesia must undergo a series of tests to determine its quality and safety.

After all of those tests have passed and the electric fan is met with the requirements that have been set, the electric fan is ready to be distributed and sold in the Indonesian market.

For the electric fan and other household electrical devices, the regulation is clearly stated in SNI IEC 60335-1:2009.
