The electric fan can be fanned, the back cover is hot, and the smell of burnt is what s going on, ca

There may be a variety of reasons for the burning smell of the back cover of the electric fan, it may be that the room temperature is too high, it may be the poor heat dissipation or overload of the fan, it may also be caused by overvoltage, undervoltage or voltage imbalance, and it may be caused by frequent start and stop or frequent forward and reverse rotation, the fan is broken, or the inlet and outlet air outlet is blocked, and the lack of oil in the bearing will cause the fan motor to heat up and have a burnt smell.

This phenomenon indicates that the internal coil of the motor has been short-circuited between turns, and the winding coil has been blackened and burned, and can no longer be used.

The motor of your electric fan is not of good quality, but it can be used, but you have to turn it off and wait for it to cool down a little before using it.

Of course it can be used, this is quite normal.

A burning smell can be caused by:

1. The electric fan uses inferior insulating paint in production, and when the insulating paint is heated, it emits a pungent odor, and the smell is getting smaller and smaller in the future use.

2. The motor shaft is out of oil in the case of not powering on the wind blade lightly, after the hand leaves, if the rotation is flexible, it is also lubricated, if you want to bring the fruit to say that the rotation is sluggish, that is, the lubricating oil is gone, remove it and drop a few drops of lubricating oil on the shaft and try to send it to the home appliance repair shop for maintenance, otherwise the motor will rotate for too long and the load will be too heavy and burn out.

How to use and maintain the electric fan:

1) Before use, you should read the instruction manual in detail to fully grasp the structure, performance, installation, use and maintenance methods and precautions of the electric fan.

2) Desktop and floor-standing electric fans must use three-pin plugs and sockets with safety grounding wires; The ceiling fan should be installed at a higher position on the ceiling and can be installed without a grounding wire.

3) The fan blades of the electric fan are important components, and they must be protected to prevent deformation during installation, disassembly, scrubbing or use.

4) When operating the switches, buttons and knobs of various functions, the action should not be too violent or too fast, nor should two buttons be pressed at the same time.

5) The speed control knob of the ceiling fan should be rotated slowly and sequentially, and should not be rotated in the position between the gears, otherwise it is easy to make the ceiling fan heat up and burn in.

6) The oil stain or dust accumulation of the electric fan should be removed in time. Do not wipe with gasoline or strong lye to avoid damaging the function of the surface painted parts.

7) If there is a hot hand, abnormal burnt smell, shaking head, slow speed and other faults in the process of using Tongji, do not continue to use it, and cut off the power supply in time for maintenance.

8) Before collecting the fan, the surface oil and dust should be completely removed, and wiped with a dry and soft cloth, and then wrapped in kraft paper or clean cloth, and the storage place should be dry and ventilated to avoid squeezing.

No, it's not poisonous.

If there is a hot hand, abnormal burnt smell, slow speed and other faults during the use of the electric fan, do not continue to use the shield, and cut off the power supply in time for maintenance. The burning smell may also be the smell of the insulating paint paint on the copper of the electric fan when it is running, so you have to smell it when buying an electric fan to see whether the paint is environmentally friendly and whether it has passed the quality judgment and testing.

Before using the electric fan, you should read the instruction manual in detail to fully grasp the structure, performance, installation, use, maintenance methods and precautions of the electric fan.

The burning smell of an electric fan indicates that it may be malfunctioning or that there is something wrong with it. But that doesn't mean all electric fans have to be deactivated. In this case, the first thing to do is to determine what is wrong with the parts of the electric fan, which needs to be investigated and inspected to determine whether it can continue to be used.

If the odor is generated by the motor, then there may be a situation where the motor is damaged. In this case, the motor may emit a metallic staggering sound, overheating, a change in the dimension of the fan, or even a complete power outage. If this is the case, it is likely that the fan has been damaged and needs to be replaced or repaired.

If the radiator overheats, it may also produce a burning odor. The cause of overheating of the radiator can be the problem of excessive dust of the electric fan, clogged fan blades, etc. If this is the case, dust and debris need to be cleaned up to allow air circulation and reduce overheating problems.

In addition, excessive dust, dirt, or other obstructions on the fan blades can also cause the fan to malfunction. In this case, cleaning the blades off may solve the problem.

Finally, there may also be some issues with the power supply part. In the case of damage to the plug or wire, a burning odor may occur. If this is the case, first check the plugs and wires for damage and decide if they need to be replaced or repaired.

Also, check that the power supply is installed securely, which is also a common cause of electric fan failure.

In short, in the case of an electric fan with a burning smell, we should not give up using it easily. It is necessary to carefully inspect to confirm the specific cause and choose the appropriate repair method to solve the problem. For general faults, such as cleaning the radiator, replacing the power supply or plug circuit, etc., the stove can continue to be used, and for serious damage, it needs to be replaced or repaired, bringing us a comfortable experience.
