Common fault of stealth fan lamp

1, poor maintenance, long lack of lubricating oil. The fan shaft part is to ensure that there is a lubricating oil, or the blade can not be dragged on the blade on it. If you are at home, you can choose to turn off the power supply and then move the wind blade. If the rotation is rigid, it is basically without lubricating oil.

2. Wear for a long time. If a fan is used for a long time, the motor will lose, and the shaft sleeve of the motor will be easily burned out after wear.

3, the fan that is caused by overheating does not turn. In the fan device, there are motors. There will be a superheated circuit breaker in the motor. If there is a short circuit in the coil winding, it will increase the calorific value in a short time. In this case, the motor will not strike.

4, the capacity of starting capacitor becomes smaller. When the fan is used for a long time, the capacity of the capacitor will be reduced, which causes the motor to start the torque to be smaller and can not drive the load.

5, electrical fault, such as line damage.

Stealth fan light non turn maintenance

1, many times caused the fan blade not to turn the reason, is the problem of poor maintenance. If the power is turned off after the power is switched off, the blades must be rotated stiffly. Some lubricants should be dripped into the shaft so that it can be lubricated without affecting the motive drag.

2. The simplest part is to replace the parts, especially the shaft sleeves, which are easy to burn off after wear.

3, if the capacitance is smaller and the fan doesn't turn, the capacitor can be removed. A new capacitor of the same type can be replaced. It is suggested that 20% of the capacitance will have better rotation effect.

4, the axial clearance of the shaft is too large, you can choose to disassemble the motor and adjust the gasket after it is disassembled. But remember at the time of motor mounting back, should pay attention to the rotor and bearings must be concentric with the diagonal twist screw slowly lubrication, finally knocking at the shaft of wood, make sure it concentric.

5. If it is due to an electrical fault, it can check the lines of the wiring, sometimes the damage of the wire and so on. It can be repaired on the problem.
