The fan is crumbling and lingering, how to help the fan rejuvenate ?

You will find that after the electric fan has been used for a long time, then it will loosen, so many electric fans will be crumbling when they are used, and they always feel as if they will fall off if they don't pay attention. In fact, at this time, there are some methods that can be used to help the electric fan rejuvenate.

This is due to the fact that the electric fan itself has a certain weight, and when the electric fan is not turned on, the electric fan is fixed on the ceiling, so the gravity it generates is not particularly large. But when you turn on the switch of the electric fan, the electric fan needs to rotate, and at this time it needs to generate a very large amount of gravity, so the screws on the ceiling will loosen due to the heavy capacity.

Therefore, when you find that the electric fan is crumbling, you must be careful not to continue to use the electric fan, because it is likely to cause the screws on the ceiling to loosen and fall off with the electric fan. At this time, you can remove the electric fan and reinforce the one screw on the ceiling.

When the screw on the ceiling is fixed, there will be no loosening in the subsequent use process. In addition, it may also be a problem with the electric fan itself, if the electric fan is used for a long time, then there will be aging of parts. At this time, the individual parts inside may also come loose.

Then you can choose to take off the electric fan and repair him, and judge what his problem is through all aspects of maintenance.

It is recommended to replace it with a new one, because the danger of the fan falling down is still great, and if you don't replace it, you have to take it for maintenance.

The fan also has its own weight, when the fan is not turned on, the expansion screw that fixes the fan on the ceiling is only affected by the gravity of the fan; After turning on the fan, the fan blades accelerate the rotation, squeeze the air to form a downward wind, and the force is mutual, and the air forms an upward thrust on the electric fan blades, so that the resultant force of the fan is gravity minus the upward thrust, so it is smaller than the downward pull when it does not turn, that is, it will not fall if it does not turn, and it will generally not fall down when it turns.

Regularly inspect and clean, just like new, it won't fall off.

Either change the motor, or just buy it again, in this case, just throw it away and buy it.

Repairing electric fans is not a technical job, either replace the motor, or trade in the old for the new, or buy it again.

Such a fan should be retired, and it will be better to buy a new one.

The crumbling fan has a safety hazard, so there is no need to repair it, just replace it with a new one.

You can take it to the person who repairs the fan, and then clean it and it will look like new.

Don't repair it again, replace it with a new one, it will cost money, effort and time to repair.

This should need to be repaired by someone with skills, and it can be replaced with a new one.
