Reasons for fan overheating and how to fix it
A fan, whether it's a table fan or even a ceiling fan, has an important function in a room to produce cool air.
In fact, there are now air conditioners that produce cooler air. But the electrical power required is also significant.
If you continue to use the air conditioner, your electricity bill may balloon!
Well, although the electricity is less than alternating current, that doesn't mean the fan will never break.
Overheating is one of the most common problems with fans. This is usually caused by a faulty fan motor.
Why can fans overheat?
Before finding a solution for an overheating fan, you must first know the cause of the problem.
This is how a fan works. Electrical energy generates magnetic energy.
This magnetic energy is converted into mechanical energy that drives the motor.
The motor is connected to a set of blades mounted at a specific angle to direct the wind energy.
Therefore, we are converting one form of energy into another. Energy that appears as a unit cannot be created or destroyed.
When a fan uses this simple principle, some energy is converted into heat energy.
Under ideal conditions, this energy consumption is negligible. However, if the internal components of the fan are not functioning correctly, the fan will generate more hot air.
A classic example is a damaged bearing, while the bearing itself connects the blades to the fan motor.
This can cause the fan blades to move more slowly, which reduces the electromotive force produced by the motor.
This extra energy has to go somewhere because it can't be destroyed. The excess energy is converted into heat, which causes the fan to overheat.
This is the most common reason for a fan overheating. However, there may be other causes that need to be investigated before repairs can be made.
Other reasons for the fan overheating are:
1. Fan lining wear
Another possible cause is wear and tear on the linings inside the fan.
Examine by looking with your eyes, or insert the motor shaft into the bushing and shake it from side to side.
If it is loose, it means that the bearing/bushing is worn out.
If the fan overheating is caused by worn bushings, remove the bearing/bush and replace it with a new one. Then replace the bearing/bush with the alternator motor.
2. Short circuit in the motor winding
If some of the motor turns on the fan are shorted, the motor will start to draw more current.
In fact, every fan motor is equipped with a thermal wick to prevent this from happening.
If the fan draws too much current, it will burn out, just like most other fuses that tend to burn out.
Another function provided is to avoid the formation of heat energy in the fan.
How to fix a fan overheating?
Okay, now you know what causes the fan to overheat.
When faced with this, you will probably contact an electronics repair service to fix it.
But in the midst of this pandemic, these services may be difficult to find given that many people are staying in their homes.
You can fix it yourself. However, if the problem is with the motor or electricity, especially if you are dealing with 230 volts, avoid fixing it yourself as it could be fatal.
1. Dust removal
Remove the front grille and remove the blades.
- Carefully remove the screws
Remove the engine cover.
- Check for dust buildup on the motor. Dust can constantly pull the fan in, causing it to overheat.
- Clean away the dust. Be careful not to damage the connections and cables while they are in place.
The next section will deal with removing the previously disconnected motor.
It needs major maintenance and repairs. If you're unsure what to do, simply clean the engine and restore everything.
2. Clamor
Unscrew the screw that secures the motor to the fan body.
- Carefully pull the motor out so as not to damage the connecting wires.
The fan must have a bushing at the front and one at the back.
Now, how to remove the liners depends on the type of liners used in the fan.
Some can be removed using nose-nose pliers, while others require a flathead screwdriver.
