The key is that the fan doesn t rotate, why is the electric fan on but not rotating

It's broken. Take it apart if you know it.

If you don't understand, take it to a repair shop and let someone else fix it for you.

Ask how much it costs to fix it.

**It's high, you don't need to repair it.

It's good to buy a new one.

Step Method.

Method Step 1:

Repair method 1, use a screwdriver to disassemble the motor, as much as possible to get some grease (butter), on the shaft and shaft sleeve to wipe some (the amount should not be too much) lubrication, the front cover and the back cover of a total of two places. After doing this step, close the front and back covers (don't be busy installing bolts) move the shaft by hand to see if it is more flexible than before, yes, you can install the motor bolts, and the boot should rotate normally after installation, at this time you have to slowly inject butter from the gap in the shaft, and judge whether it is suitable by hearing and vision.

Method Step 2:

Repair method 2, see if the terminal is good, whether the timer is normal, whether the capacitor terminal is good, after checking these, I believe that your fan fault can also be completely eliminated.

Method Step 3:

Repair method 3, poor power contact, try to change a few more power supplies, if the internal circuit of the fan is not in good contact, you need to ask an expert to disassemble and inspect. (When stopping, you can move the fan blade by hand, and it feels light).

Method Step 4:

Repair method 4: Disassemble the motor, wipe the dirt on the motor shaft and bearing with diesel clean, and then apply an appropriate amount of motorcycle oil and reinstall it. Replace capacitors of the same size or increase the capacity by 20%.

Precautions. If the above repairs are not possible, then hurry up and warrant it!

<> the electric fan is turned on but does not rotate, it may be a deficiency, because the rotating shaft part of the electric fan needs to add lubricant; It may be because the motor time is too long, so that the internal resistance of the motor becomes larger, and the load capacity becomes lower, resulting in the inability to drive the fan blade to rotate; It may also be that the motor is overheated, causing the load capacity of the motor to change to the poor burning, resulting in the inability to carry the load of the hand shed.

This answer is applicable to most brands of electric fan models such as Emmett, Gree, and Dyson.

1. Lack of lubrication of the fan motor: when the lubrication of the motor is not enough, it is necessary to add lubricating oil to the rotating shaft part, after removing the fan blade, if the rotating shaft rotates normally, it means that the motor is not broken, after disconnecting the power supply, add lubricating oil to the rotating shaft part;

2. The fan motor is burned out: if the electric fan is used for too long, the motor will be lost, and the shaft sleeve of the motor will be easily burned out after being worn, and the motor will be used for a long time, which will also make the internal resistance of the motor larger, so that the load capacity will be lower, and the fan blades will not be able to rotate;

3. Overheating of the fan motor: When the Qingshen motor is overheated, it will also cause the motor to have a weak load capacity and the motor power to become low, resulting in a clear bending and inability to drive the load;

4. The capacitance capacity becomes smaller: if the electric fan is used for too long, the capacitance capacity will also be reduced, resulting in the starting torque of the motor becoming smaller, and the load cannot be driven;

5. The buried front clearance between the axial direction of the rotating shaft of the motor is too large: when the axial clearance of the rotating shaft of the motor is too large, it will also cause the inability to drive the load. At this time, the motor can be disassembled, and the problem of excessive axial clearance of the rotating shaft can be solved by adjusting the gasket.

There could be the following reasons:

1.Power failure: Check whether the power supply is normal and whether there is a current output.

2.Motor disturbance fault: Check whether the motor is damaged or stuck, and the motor needs to be replaced.

3.Faulty fan blades: Check whether the fan blades are loose or damaged, and the blades need to be replaced.

4.Fan bearing failure: Check the bearing for damage or lack of lubrication, and need to replace the bearing or add lubricating oil.

5.Controller failure: Check whether the controller is working properly and need to replace the controller.

6.Other faults: such as fan line failure, fan switch failure, etc., which need to be repaired or replaced by a virtual upgrade.

There may be the following reasons: Be careful to shoot.

1.Power failure: Check whether the power supply is normal and whether there is a current output.

2.Motor failure: Check if the motor is normal and if there is any damage or stuck.

3.Faulty fan blades: Check if the fan blades are normal and if they are damaged or stuck.

4.Controller Failure: Check whether the controller is normal, damaged or invalid.

5.Circuit fault: Check whether the circuit is normal, whether there is any damage or short circuit.

If none of the above methods can solve the problem, it is recommended to contact a professional maintenance personnel for inspection and repair.

There could be several reasons for this:

1.Fan power failure: Check whether the power plug is plugged in tightly and whether the power cord is broken or poorly contacted.

2.Fan motor failure: Check whether the fan motor is damaged or aging, and the motor needs to be replaced.

3.Fan blades know that the remaining pieces of the cassette are blocked: Check whether the fan blades are stuck by foreign objects and need to be cleaned.

4.Fan shaft wear: Check whether the fan shaft is worn, and need to replace the lap roller shaft.

5.Fan circuit fault: Check if the fan circuit is damaged and needs to be repaired or replaced.

If none of the above methods can solve the problem, it is recommended to contact a professional maintenance personnel for maintenance.
