How to fix my home appliance fan if it doesn t turn How to fix it if the electric fan doesn t turn?

You can check the plug to see if the line inside is broken, if the line is not broken, turn on the electric fan and then use the item to turn the fan blade to see if it moves, if it doesn't work, then take the electric fan apart, see if the power cord inside is broken, if it is not broken, then you can not deal with it for a long time, just find a repair home appliance OK!

The motor coil is partially short-circuited, and the motor needs to be replaced.

The starting capacitor of the motor is broken, or the rotor and stator of the motor are rubbed, and the windings have broken points. Find a repairman to fix it.

There are several reasons why the fan does not rotate, if it does not rotate smoothly when it is energized, and it does not rotate after it is energized, and it turns when the fan blade is turned by hand, indicating that the starting capacitor is damaged. Because the function of the starter capacitor is to give an external force to make the motor spin. The single-phase motor cannot form a rotating magnetic field on the stator core, and a capacitor needs to be added to generate a rotating magnetic field before the motor will rotate.

If you don't feel good when you dial the fan blades by hand when the power is not on, it may be that the bearings are damaged or the front and rear bearings are not concentricity, first loosen the motor fixing bolts, and slowly adjust them evenly until the rotation is smooth. If the motor shaft is locked after power-on, but it can't rotate, it is the motor has a lack of phase, and the winding is broken, open the motor to find the broken wire, connect the wire on the line, and the patent leather on the enameled wire must be scraped off when wiring, otherwise it will not be energized.

Pay attention to check whether the motor is seriously heated, if the heat is serious, it means that the windings of the motor have a short circuit. The coil needs to be rewound or the motor replaced. If there is no obvious temperature anomaly, just operate as follows, and the problem can generally be solved:

1. Disassemble the motor, wipe the dirt on the motor shaft and bearing with diesel clean, then apply an appropriate amount of motorcycle oil, and reinstall it.

2. Replace the capacitor of the same specification, or increase the capacity by 20%.

The repair method for the electric fan not rotating is as follows:

Tools: fan, lubricant, screwdriver, capacitor.

1. If the fan blade is turned off and the power is turned off, you should use some lubricating oil to drip into the shaft so that it can be lubricated, so as not to affect the motor to drag the fan blade.

2. In view of the non-rotation of the fan blade caused by wear, the easiest thing is to replace the parts, especially the shaft sleeve, which is easy to burn off if it is worn out.

3. If the capacitor capacity becomes smaller and the fan does not rotate, you can remove the capacitor and replace it with a new capacitor of the same model, it is recommended to choose a capacitor that is 20% larger than the original capacitor, which will have a better rotation effect.

4. If it is because of electrical faults, you can check the wiring lines, sometimes the wires are damaged, etc., and the problem can be repaired.

Maintenance of electric fans

1. Read the instruction manual carefully before using the electric fan, and fully grasp the structure of each part of the electric fan and the correct way to use it.

2. The fan blade of the electric fan is an important component, and it must be protected to prevent deformation during installation, disassembly, scrubbing or use.

3. Clean the electric fan regularly to avoid the dust of the electric fan affecting the work of the electric fan. Generally, after a long time, electric fans are easy to get a lot of dust on the fan blades. At this time, it is necessary to clean up the dust on the fan blades.

Be careful not to wipe it with gasoline or strong lye to avoid damaging the surface paint.

4. After the end of summer, the electric fan should be collected, and the electric fan should be thoroughly cleaned before collecting, and then wrapped in a cloth cover and placed in a dry and stable environment.

Electric fans are one of our must-have appliances in summer. He is small and flexible, cheap, easy to use, and effectively dispels the summer heat for people. It's a must-have artifact at home.

However, electric fans can also malfunction after a long time. Sometimes it just stops inexplicably. So how to repair the electric fan if it doesn't turn?

Let's take you to solve this problem.

1. How to repair the electric fan if it doesn't turn.

1. Let's check the electric fan first to see if it is because of the lack of lubricating oil. If there is a lack of oil, it will be reflected in the noise generated when rotating, and if it is more serious, it will simply stop and not rotate. It is also very laborious to manually rotate the blades by disconnecting the electric machine.

The solution to the problem is to add lubricating oil to him.

2. We often encounter that the electric fan can't turn up or we need to pluck it with our hands before it moves. But after a while, I stopped again. This may be due to the fact that the capacitance has been reduced for too long, and the power is not enough to support the fan rotation.

The best solution is to replace it with a new capacitor. The capacity of the capacitor can be a little larger than the original one.

3. The age of the fan is too long, and it will be used for a long time. The motor inside the fan is too worn, not resistant to high temperatures, and easily damaged. The solution is to find the worn parts and replace them with new ones.

4. The axial distance of the rotating shaft of the motor is too long to withstand the pressure, resulting in a stoppage. You can disassemble the motor, adjust the axial distance of the shaft and reinstall it. Note: The rotor should be concentric with the bearing, and the screws should be tightened after installation.

Finally, it is important to tap the hinge firmly to confirm that it is concentricly put back in. Be careful and careful, otherwise it will cause secondary damage and will not achieve the effect of repair.

Summary: The above is the maintenance method for the electric fan not turning. First of all, we have to figure out why it doesn't rotate.

Which part is broken or simply lack of lubricating oil. Only when the cause is found can a suitable solution be formulated. You should also be careful when operating.

If you are careless, it is easy to cause secondary damage, which not only fails to achieve the purpose of repairing the electric fan, but also makes the situation of the electric fan worse, and the gains outweigh the losses.

In life, due to the frequent use of electric fans, there are various failures of electric fans, among which the situation that the electric fan does not rotate is the most common one. So what is the reason why the electric fan does not turn? How to repair the electric fan if it doesn't turn?

Let's take a look at it together.

How electric fans work.

The principle of an electric fan is relatively simple, and it is generally learned in junior high school physics courses. The current in the electric fan is alternating current, and the working principle is that the energized coil rotates under force in a magnetic field. The electrical energy is converted into mechanical energy, turning the fan blades, and at the same time, due to the resistance of the coil, some heat energy will be generated, so the surface of the general electric fan will be hot if it is used for too long.

The reason why the electric fan does not turn.

First of all, we still have to confirm whether there are some external reasons. For example, the plug is not plugged in properly, the fan switch is not fully turned on, etc., the general fan should also pay attention to whether it is turned off regularly, if these are not problems, it may be the cause of the electric fan itself. The reasons for the electric fan itself may include that the fan blades have been used for too long, and the internal resistance of the motor has become larger, resulting in the fan blades not being able to rotate normally; The load capacity of the motor belt deteriorates due to fan overheating, resulting in the inability to rotate; The protection device inside the motor is overheated and short-circuited; The starting capacitance capacity of the electric fan is reduced; Excessive axial clearance of the shaft of an electric fan may also cause problems with the electric fan.

The electric fan does not turn the repair method.

1.In many cases, the reason why the fan blades do not rotate is poor maintenance. If the blade is stiff after turning off the power, you should use some lubricating oil to drip into the shaft so that it can be lubricated so as not to affect the motor to drag the blade.

2.For the fan blades caused by wear and tear do not rotate, the easiest is to replace the parts, especially the shaft sleeve, if the wear is easy to burn after digging.

3.If the capacitor capacity becomes smaller and the fan does not rotate, then you can remove the capacitor and replace it with a new capacitor of the same model, it is recommended to choose a capacitor that is 20% larger than the original capacitor, so that the rotation effect will be better.

4.If the axial clearance of the shaft is too large, you can choose to adjust the gasket after disassembling the motor. But you must remember that when installing the motor back, you must pay attention to the rotor must be concentric with the bearing, slowly tighten the lubricating screw diagonally, and finally knock the shaft with a wooden handle to ensure that it is concentric.

It is very easy to disassemble the motor, but it is more difficult to install it back, don't do it casually, otherwise it is easy to repair the fan. If the bearing core is severely worn when the motor is removed, it is necessary to replace it with a new part.

5.If it is due to an electrical fault, you can check the wiring line, and sometimes if the wiring is damaged, you can repair the problem.

1. Motor lubrication is not good: the priority is that the motor lubrication is not good, the shaft part should be lubricated with oil, the fan blade is installed on the motor can not be dragged, and after removal, the shaft can still run normally, which shows that the motor is not broken. How can you tell if you are short of oil?

That is, after disconnecting the power supply, you gently dial the fan blade, and find that the rotation is a little stiff, which means that the oil is gone, and the rotation is very easy, indicating that the lubrication is good, and this is not turned for other reasons.

2. Excessive motor loss: Secondly, you have to consider how long the electric fan has been used, the motor will be lost, and the shaft sleeve of the motor will be worn out, and it is easy to burn out. If the motor is used for a long time, the internal resistance of the motor will also become larger, and the force of the load energy will become lower, resulting in the inability to drive the fan blade to rotate.

3. Motor overheating: motor overheating will also cause the motor to deteriorate with load capacity, and the active power of the motor will become low, resulting in the inability to drive the load.

4. Short circuit of coil winding: From the inside of the motor, it has a protection device inside, and there is an overheating circuit breaker, that is, the coil winding part is short-circuited, resulting in a sharp increase in calorific value, and the circuit breaker is broken. This rarely happens.

5. Capacitance capacity reduction: Another is that the starting capacitance capacity becomes smaller, although those parameters are written on the nameplate, but after a long time, the capacitance capacity will be reduced, resulting in the starting torque of the motor becoming smaller, unable to drive the load. This is simple, remove this capacitor, and then replace it with a new one, and the same model should be fine.

But it's better to change to a 20% larger one than the original, and you will get better results.

6. The axial clearance of the rotating shaft of the motor is too large: if the motor is disassembled, the axial clearance of the rotating shaft is too large, and it should be adjusted by adjusting the gasket. When installing the motor, the rotor must be concentric with the bearing, the screws should be slowly tightened diagonally, and then the screw should be knocked on the shaft with a wooden handle to make it concentric.

It's easy to disassemble the motor, but it's not easy to install it back again, don't let the above situation happen, otherwise, it will be repaired directly.
