In fact, there are currently air conditioners that produce cooler air. But the electrical power required is also large.

If you keep using the air conditioner, your electric bill could balloon!

Well, even though the electricity is less than AC, that doesn’t mean the fan never broke.

One of the most common problems with fans is overheating. Usually, this is caused by a fan motor malfunction.

Why can fans get hot?

Before finding a solution for an overheating fan, you must first know the cause of the problem.

This is how the fan works. Electrical energy generates magnetic energy.

This magnetic energy is converted into mechanical energy that drives the motor.

The motor is attached to a set of blades set at a certain angle to direct the wind’s energy.

So we convert one form of energy into another. Energy, which appears as a unit, cannot be created or destroyed.

When a fan uses this simple principle, some of the energy is converted into heat energy.

Under ideal conditions, this energy is negligible. However, if the inside of the fan is not working properly, the fan will generate more hot air.

One classic example is a damaged bearing, while the bearing itself serves to connect the blades to the fan motor.

This can make the fan blades move slower which reduces the electromotive force generated by the motor.

This extra energy has to go somewhere because it cannot be destroyed. Excess power is converted into heat, and this is what causes the fan to overheat.

This is the most common cause of fan overheating. However, there may be other reasons that need to be analyzed before the repair is done.

Other causes of fan overheating are:

1. Worn propeller liners

Another reason could be wear of the bushings inside the fan.

Check by eye, or insert the hub of the motor into the bushing, rocking it from side to side.

If it is loose, then the bearing / bushing is worn out.

If the fan’s heat is caused by wear of the bushings, remove the bearing/ bush and replace with a new one. Then replace the bearing / bushing with the dynamo.

2. Short circuit in the motor winding

If some of the motor windings on the fan are shorted, the motor will start drawing more current.

In fact, every fan motor is fitted with a thermal fuse to prevent this from happening.

If the fan is drawing too much current, it will burn like most other fuses tend to burn out.

Another function provided is to avoid the build-up of heat energy in the fan.

How to fix fan overheating?

Well, now you know what causes the fan to overheat.

When you encounter this, you will probably contact the electronics repair service to fix it.

But in the midst of this pandemic, it can be difficult to find these services given that many people are staying at home.

You can fix it yourself. However, if the problem is with the motor or electricity, especially if you are dealing with 230 volts, avoid repairing it yourself as it can be fatal to yourself.

1. Clean the dust

– Remove the front grille and remove the blades

– Carefully remove the screws

– Remove the engine cover

– Make sure that no dust has accumulated on the motor. Dust can constantly pull the fan in and thus overheat it

– Clean up the dust. Be careful not to damage connections and cables while they are in place.

The next section will deal with removing the previously disconnected drive.

It needs major maintenance and repairs. If you are not sure what to do, just clean the engine and restore everything.

2. bushing

– Loosen the screw that secures the motor to the fan body

– Pull the motor out carefully so as not to damage the connecting wires

The fan must have one bushing in the front and one in the back

Now how you remove the bushings depends on what type of bushings are used in the fan.

Some can be removed with nose pliers, while some require a flat head screwdriver.
