What is the problem that the electric fan does not respond after being powered on?

There are many reasons why the electric fan does not respond when it is powered on.

First, the plug and the socket contact is poor, you can change to a normal socket to try, if there is still no response, that is the motor problem.

Second, if the plug is fine, the motor problem is:

1.If the fan timer is faulty, if you have the ability to do it, you can check whether the contacts can be turned on and off well.

2.If the fan has a unit switch, you can check the gear switch failure, if it is not in good contact, you can adjust the spacing of the contacts a little closer.

3.Check the fan starting capacitor, try it with the substitution method, that is, replace it with a good capacitor of the same specification, if it is normal, it means that the capacitor is faulty.

4.If there is still no response, then there must be a problem with the motor, usually the motor winding has an inter-turn short circuit, you can only change to a fan motor of the same specification, a better motor is about 30 yuan.

1. No internal power: The wiring of the fan switch and timer is disconnected and reopened, resulting in the fan not being energized normally. 2. Failure of starting capacitor:

The capacitance of the starting capacitor decreases, resulting in the failure to start the motor properly. 3. Lack of oil in the bearing: The lack of lubricating oil in the bearing of the fan motor makes it difficult for the fan blade to rotate.

4. Bad motor coil: The fan motor coil is burned out, resulting in the inability to operate normally.

If there is no problem with the power supply of the fan, and the motor has power but does not start working, you can overhaul it according to the following methods:

First of all, turn the motor shaft or fan blade by hand without power to see if the rotation is flexible? If there is resistance to rotation, it means that the motor bearing is seriously worn or the lubricating oil is dry, and the new bearing should be replaced or lubricated to make it rotate flexibly without resistance. When installing the fixed motor, it is necessary to tighten the screws diagonally, and it must be tightened gradually, not in one step, and at the same time, it is necessary to hit the shaft back and forth with a wooden handle driver to ensure that the shaft is concentric with the bearings at both ends, so that the rotation will be flexible and without resistance after fastening.

If it turns flexibly without resistance, there are several reasons:

First, the capacitor is damaged, and a new capacitor of the same capacity should be replaced.

The second is that there is an inter-turn short-circuit fault in the coil, and the resistance value of the running winding and the starting winding can be measured with a multimeter to judge the quality of the winding. If the resistance value is abnormal, it is necessary to replace the motor with a new one.

1. The internal power is not on, the wiring of the fan switch and timing bai device is disconnected, resulting in the fan not being able to power on normally. Listen to whether there is a motor sound or not, and you can judge. Workaround:

Replace the damaged part, or reconnect the wires. 2. The starting capacitor fails The capacity of the starting capacitor decreases, resulting in the failure to start the motor normally. The hand can turn the fan blade, which can be judged.

Solution: Replace the CBB61 starting capacitor of the same model. Electric fan, also known as fan and fan, is a household appliance that uses an electric motor to drive the fan blades to rotate to accelerate the circulation of air, mainly used to cool off the heat and circulate the air.

It is widely used in homes, classrooms, offices, shops, hospitals and hotels. A fan is mainly composed of components such as a fan head, blades, grille, and controls. The fan head includes an electric motor, front and rear end covers, and a moving head air supply mechanism.

The main component of the electric fan is: AC motor. Here's how it works: Energized.

If the electric fan does not respond after powering on, first check whether the socket line of the electric fan is out of power, and secondly, measure whether the switch of the electric fan is normal, and whether the motor of the electric fan is abnormal?

1. There is no power on the inside.

The wiring of the fan switch and timer is disconnected, causing the fan to not be powered on normally.

Listen to whether there is a motor sound or not, and you can judge.

Solution: Replace the damaged part, or reconnect the wires.

2. Failure of starting capacitor:

The capacitance of the starting capacitor decreases, resulting in the failure to start the motor properly.

The hand can turn the fan blade, which can be judged.

Solution: Replace the CBB61 starting capacitor of the same model.

This means that your electric fan has been broken, because the normal electric fan will operate normally after powering on, if you press the switch, the fan does not rotate, it is a problem with the electric shaft, you can find a maintenance master to help deal with it.

After the electric fan is powered on, there is no response at all, indicating that there is no power supply. Check to see if there is a break in the power cord of the electric fan, or if the fuse inside is burned.

If the electric fan does not respond after being energized, it is estimated that it is broken, and the resistance wire is broken, otherwise this situation will not occur.

What is the reason why the electric fan does not respond when powered on? 1. Broken motor coil: The motor coil of the fan is burned out, resulting in the inability to operate normally. 2. No internal power: The wiring of the fan switch and timer is disconnected, resulting in the fan not being able to do so.

If the electric fan doesn't respond after it is powered on, I think this should still need to be paid attention to, this may be because the power station is faulty, or the fan is faulty, so it is possible that she has no response.

It should be that the switch or power supply insurance is broken, and I am really helping you look forward to it

Electric fanPower on but not turning Reason:

1. The electric fan does not rotate if it is electrified, which may be a quality problem of the electric fan itself, so when buying an electric fan, it is recommended that you buy a big brand, and the quality will be guaranteed to a certain extent.

2. If the electric fan is not used for a long time, improper storage will also cause the electric fan to not rotate.

3. If you don't clean the dust on the electric fan for a long time, it will also cause the electric fan to not rotate.

4. There is no lubricating oil in the bearing of the electric fan, and the electric fan will not rotate.

5. If there is a problem with the motor of the electric fan, even if the electric fan is plugged in, it will not rotate.

How to store the electric fan:

1. The electric fan needs to be stored in a dry place, if the storage location is too humid, it will have a certain impact on the electric fan.

2. If you don't use the electric fan for a long time, it is recommended that you can clean it regularly.

3. When storing the electric fan, it is recommended that you can disassemble the parts of the electric fan and store the fan blades separately.

Hello, dear, I am happy to answer for you: the situation that the electric fan does not respond when the power is turned on may be due to the following reasons: 1

Power issues. Make sure the power plug is connected to an electrical outlet. Check the power plug for damage, remove the plug and check the plug and socket for dust or oxide.

2.Problems with power lines. If there is no damage to the power plug and socket, check whether the power supply line is normal.

It is possible that the line is faulty or the fuse is burned out. 3.Problems with fan switches or power switches.

Check whether the fan and power switch are normal. If the controller or switch is damaged, the fan may not be able to activate the shed. 4.

Motor problems. The motor is the key component that drives the fan to turn, and if the motor is damaged, the fan cannot start. 5.

Faulty power cord of electric fan. Check the power cord of the electric fan for breaks or frayed. If you've checked all of the above and the fan still doesn't work, you may need a more advanced inspection and repair.

It is recommended to leave it to the specialty. The maintenance personnel of the industry deal with it. Dear, I hope mine is helpful to you

The electric fan is powered on normally but there is no response when pressed, kiss, hello! After power-on, no matter according to the first gear, the motor will have a sense of vibration, or a whining sound, and the spindle can not rotate freely, you can try to fill the oil, inject oil from the spindle, until the spindle can rotate freely, but it is best to remove the motor, carefully take off the front and rear shells, the central hole of the spindle and the front and rear casings are oiled, wipe with a soft cloth, and re-oil, the front and rear ends of the spindle are the same, after reinstalling it, you should turn it by hand, **There is a card, just use a screwdriver to gently knock it, However, it is recommended to hire an electrician to do it, if you are not professional, you may damage the motor, and you will not lose it; If the spindle can be moved, it will take a while to move after starting, and the speed is very slow, so check the capacitance and replace it. If the above two points are not, it is not moving, you can check whether there is a white, small grain of temperature control protection on the motor is damaged, directly connect the two levels, if it still can't work, only change the motor, it is best to hire someone to change the motor, unless you have basic electrician knowledge.

Hope it helps! If my answer is helpful to you, please give a like (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the driving force for my progress. Finally, I wish you good health and a good mood!

What is the problem that the electric fan does not respond after being powered on?

1.If the electric fan generator is overheated and does not rotate after powering on, you can ask a professional to repair it. 2.

The electric fan generator lacks lubricating oil, which causes the electric fan to not rotate after powering on, which can be solved by dripping some lubricating oil into the generator. 3.The electric fan generator is worn out and the load capacity becomes low, resulting in the electric fan not rotating when it is energized, and the parts can be directly replaced.

Dear, hello, the reasons and treatment methods for the electric fan to not respond to the power on are as follows: 1. If the replacement wire will be damaged because of the wire, it has been used at home for too long to make it age, resulting in the internal core breakage, at this time, just replace it with a new wire. Second, add lubricating oil in a timely manner, such as a fan this seasonal electrical appliance, many families will be directly put away after use, undefeated ruler maintenance measures, and then take out the use in the second year, it is anxious to appear that the blade rotation is not flexible, and the phenomenon of stiffness occurs.

Third, the motor damage to be repaired when looking for faults, if it is found that the motor is replaced, most of them can not be repaired, at this time you need to send it to a professional maintenance point, if the maintenance is too high, you can directly replace it. Fourth, the capacitor capacity of the new capacitor will also cause the fan not to rotate, if the test is found to be caused by this reason, it should be removed and replaced with a new capacitor of the same model, generally choose 20% larger than the original capacitor, the effect is yes.
