How to solve the problem that the electric fan does not turn and there is a loud noise | 18 inch stand fan price
Electric fan is a popular electrical appliance in summer. People like it when it is used, not only because it is very convenient, it can be moved back and forth in various rooms. But if it can’t rotate normally, especially when it is accompanied by Weng Weng’s noise, it will make people feel more hot. Faced with this helpless phenomenon, do you know how to solve it? Then, let’s take a look at how the electric fan makes a noise if it doesn’t turn. What should I do?
1. View the bearing
When the fan does not rotate, the bearing needs to be checked. The editor here reminds everyone to make sure that the power is turned off before checking. Then turn it with your hands again to see if it can turn smoothly. If it turns smoothly, it indicates that it is not a bearing problem. Then disconnect the starting capacitor to see if the noise disappears. If there is no sound anymore, turn it by hand to see if it can be turned. If it can turn, it means that it is a problem with the starting capacitor, and it needs to be replaced in time.
Second, the detection capacitance
In many cases, the fan fails, most of which is related to the capacitor, so how to make further judgments? At this time, an artifact is needed, that is, a multimeter. If it is found that the capacitor has leakage and the capacity is too small, it indicates that it has affected the normal operation. The maintenance personnel should be contacted for the next step.
Three, check the switch
If some switches on the fan are used incorrectly, it will also cause a loud sound and inability to rotate. At this time, you can check the timing switch, gear selector switch, anti-fall switch and other places to see if they have poor contact or damage. If they are broken, they should be replaced. In this way, the problem should be solved, and it can be used normally at home.
The above is the relevant content about the sound of the electric fan without turning, I hope it can be helpful to everyone!
