3. Lianchuang Technology Group adheres to independent innovation and is oriented by consumer demand. With more than 280 independent intellectual property rights, self-developed air-conditioning fans have become the vane of the global home appliance market. At present, Lianchuang Technology Group has fully mastered the core technologies and core self-operated capabilities of home appliances such as air-conditioning fans, electric fans, electric heaters and water heaters, and has a complete air-conditioning fan industrial chain and gift product group in China.
Second, once the Lianchuang electric fan is started, it will not turn.
When using Lianchuang electric fan, it is inevitable to encounter various problems, such as that Lianchuang electric fan will not turn when it is started. Let's see what it feels like to start the Lianchuang electric fan without turning.
1, poor internal contact of Lianchuang electric fan switch. You can turn on the switch for maintenance, and replace it with a new switch if it is seriously worn.
2. The capacitor terminal of Lianchuang electric fan has poor contact, and all wires can be fastened or welded.
3. The shaking part of Lianchuang electric fan is too tight, and it gets stuck when it turns to a certain position. Repair the fastening parts to make them rotate flexibly.
4. If the incoming wire of Lianchuang electric fan is damaged, short-circuited or broken, it should be replaced with a new wire immediately.
5. The cable of Lianchuang electric fan has poor contact. Find out the poor contact of the cable and weld it again.
6. The main and secondary windings of Lianchuang electric fan are open or short-circuited and touch wires. Reconnect the broken wire, and if there is a serious short circuit, rewind the fan winding.
Third, the Lianchuang electric fan does not turn and hum.
When using Lianchuang electric fan, some people say that Lianchuang electric fan will not turn or even buzz. Let's take a closer look.
1, it may be that the rotor shaft of Lianchuang electric fan motor is stuck due to lack of oil;
2. It may be that the front and rear end covers of the motor of Lianchuang electric fan are deviated, resulting in the rotor shaft being stuck;
3. It may be that the starting capacitor of Lianchuang electric fan is broken (or the capacity is reduced), resulting in no current in the coil of the starting winding (or the current is too small), and the motor cannot rotate;
4. It may be that the coil of the starting winding of Lianchuang electric fan motor is broken. At this time, there is no current flowing through the starting winding, and it will not rotate but just hum. You can turn the fan blades with slight force without power supply to see if the motor can rotate easily. If it can rotate easily, it is generally the fault of starting capacitor and starting winding. If it is difficult to rotate, it is usually the reason why the rotor is stuck.
