What is the reason for turning on the air conditioner, the main engine turning, and the extension no

1. The pressure protection switch is faulty.

2. Too much refrigerant causes protective shutdown.

3. The ambient temperature is too high, resulting in system protection. The ambient temperature is too high, the sun is shining without shade, and the outdoor unit is poorly ventilated, which will cause the compressor to overheat in summer, resulting in the air conditioner not rotating.

4. Pay attention to whether the outdoor unit has working sound (including outdoor unit fan and compressor). If the outdoor unit fan is running, the control circuit is basically normal. At this time, you should observe whether the compressor starts or not, and if the compressor does not start, you should check whether the power supply is normal.

5. If there is no problem with the above checks, then you need to check whether the capacitor is damaged and whether the overload protector is short-circuited.

6. Sensor failure. Use a multimeter to measure the resistance value of the outdoor unit coil unit sensor, if the sensor resistance value deviates from the normal value or there is an open circuit or short circuit fault, the sensor needs to be replaced.

7. AC contactor failure. Power on the AC contactor, measure the outlet end of the AC contactor with a multimeter to see if there is a voltage of 380V, if not, it means that the AC contactor is damaged internally, and a new AC contactor needs to be replaced.

- Is the air conditioner malfunctioning? With my 7 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.

First: When the air conditioner fails, you can go to the [air conditioner failure** network] to inquire, down to the brand and model of the air conditioner. Universal remote control** query can go to the universal remote control area for inquiry.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The air conditioner is not refrigerated or does not refrigerate.

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

If you still don't understand, it is recommended that you go to the [Air Conditioning Fault **Net] basic knowledge area and take a look at the maintenance cases to get started.

I hope you get better and better, and the new year will be smooth, all your wishes will come true, you will be healthy, and your family will be happy.

- Finally, I wish you all the best in your work, fix the air conditioner as soon as possible, and live happily ———

- If you think it's good, please click on the answer, give a good review, and wish you a better life———

It may be a circuit problem, or it may be that the indoor fan is broken, and it may be directly after-sales**.

Hello according to your problem description: If the air conditioner main unit does not turn but there is wind, it may be due to the following reasons:1

Faulty control board: If the circuit on the air conditioner's control board fails, the hood may cause the main unit to not rotate, but there will still be wind. 2.

Motor failure: If the motor of the air conditioner unit fails, it will also cause the main engine to not rotate, but there will still be wind. 3.

Capacitor failure: A failure of the capacitor in the main unit of the air conditioner will also cause the main engine to not rotate, but there will still be wind. 4.

Power failure: The power supply failure of the air conditioner will also cause the main unit to not rotate, but there will still be wind. If you encounter this situation, it is recommended to contact the air conditioner maintenance service immediately for repair and cracking, so as not to affect the use of the air conditioner.

If the outside unit of the air conditioner does not rotate but the internal unit has air supply, it may be due to the following reasons:

1.Power supply problem: Check whether the power supply of the air conditioner is normal and whether there is a current output.

2.Motor problem: Check whether the motor of the air conditioner is normal and whether it needs to be replaced.

3.Connection problems between the internal and external units: Check whether the connection between the internal and external units of the air conditioner is normal, and whether there is any looseness or damage.

4.Control panel problem: Buried in the front land to check whether the control panel of the air conditioner outside the bend is normal and whether it needs to be replaced.

5.Piping problems: Check whether the piping of the air conditioner is normal, and whether there are problems such as fluorine leakage or blockage.

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

<> the air conditioner does not rotate but the air supply is provided to the internal unit, it may be caused by the failure of the compressor starting capacitor of the outdoor unit, the failure of the power supply substrate of the outdoor unit, the failure of the fan motor capacitor of the outdoor unit, the failure of the compressor of the outdoor unit, and the lack of signal power supply to the outdoor unit of the indoor unit.

This answer is applicable to most brands of air conditioners such as Gree, Midea, and Haier. The town is merged before.

Reasons why the air conditioner does not rotate but there is wind: 1. Failure of the starting capacitor of the compressor of the outdoor unit; 2.

The power supply board of the outdoor unit is faulty; 3.Outdoor unit, fan, motor, capacitor failure; 4.Outdoor unit compressor failure; 5.

The indoor unit has no signal power supply to the outdoor unit. The outside of the air conditioner does not turn to the wind, and the internal unit is windy - the repair method <>

1.Insufficient refrigerant causes the outdoor unit not to rotate (1) Failure analysis: Refrigerant plays a very important role in the operation of air conditioning.

If the air conditioner is low or leaking, the air conditioner will work properly without the accompaniment method. At this time, the compressor in the outdoor unit cannot absorb the refrigerant, complete the refrigeration cycle, and the compressor cannot work, which eventually causes the outdoor unit to not rotate. (2) Fault maintenance:

If the refrigerant of the air conditioner is insufficient, first check whether the air conditioner has refrigerant leakage, if there is a leak, you need to repair the leaking part before adding refrigerant to the air conditioner. 2.The failure of the connection line of the internal and external units causes the external unit of the air conditioner to fail to rotate (1) Fault analysis:

The outdoor unit of the air conditioner is connected with the indoor unit, and the internal and external units of the air conditioner interact with each other at the same time to play the due role of the air conditioner. If the connection cable between the indoor unit and the outdoor unit of the Ashima air conditioner fails, it will also cause the outdoor unit of the air conditioner to fail to rotate. (2) Fault maintenance:

If the air conditioner connection line fails, all we can do is to check the connection line, troubleshoot, and check which line is faulty before maintenance, so that the outdoor unit of the air conditioner can operate. 3.Component damage causes the external air conditioner to fail to turn (1) Failure analysis:

After long-term use, the parts of the air conditioner unit are damaged, which will also cause the air conditioner unit to fail to rotate. (2) Fault maintenance: If the parts in the external machine of the air conditioner are damaged, we need to repair or replace the damaged parts to ensure that the air conditioner can work normally during the later operation.

4.Air conditioner overheating protection makes the air conditioner automatically stop running (1) Fault analysis: When the air conditioner does not rotate, we first check whether the heat dissipation effect of the air conditioner condenser is good.

If the heat dissipation effect of the air conditioner condenser is poor, the air conditioner will overheat, and the air conditioner will automatically stop running to protect itself. (2) Fault maintenance: In view of this situation, the air conditioning condenser should be cleaned and maintained first to ensure the good heat dissipation effect of the air conditioning condenser.

At the same time, we need to pay more attention here. When the air conditioner is maintained, the outdoor unit should be cleaned and maintained regularly to ensure that the outdoor unit is running well.

If the indoor unit of the air conditioner is supplying air normally, but the outdoor unit is not rotating, there may be the following reasons:

1.Power supply problem: Check whether the power supply of the outdoor unit of the air conditioner is properly powered to ensure that the plug is connected correctly and the circuit is not disconnected. It is also necessary to check that the fuse is blown and may need to be replaced if it burns or blows.

2.Motor problem: The compressor of the outdoor unit is usually driven by the motor, and when the motor fails, the outdoor unit may not operate properly. This can be caused by damage or malfunction of the motor and needs to be serviced and replaced by a professional technician.

3.Refrigerant problem: The refrigerant in the air conditioning system is used to transfer and regulate heat, and if the refrigerant is insufficient or leaks, the normal operation of the system may be affected. This may cause the outdoor unit protection mechanism to be activated, making the outdoor unit unable to operate normally.

4.Control circuit problems: The control circuit of the air conditioning system may be cracked and faulty, resulting in the outdoor unit not receiving the correct commands. This may require checking and repairing faulty connections and circuits of the control lines.

Since electrical and refrigeration systems are involved, repairing air conditioning faults is best done by a professional technician. If you encounter this problem, it is recommended that Lianmo Cave is the customer service provider of the air conditioner repair service provider or the air conditioner manufacturer for professional help and advice.

The air conditioner is normal and the outside unit does not turn the solution:

1. If the air conditioner is working normally, and suddenly the sound of the external unit becomes louder, you should check the heat dissipation of the condenser, and you can slowly drip water onto the external radiator of the room.

2. Check whether the shock absorption of the compressor foot is damaged, and check the iron foot of the fixed outdoor fan.

3. If the whole machine does not work, check whether the indoor unit has power to be transmitted to the external unit, and find professional maintenance personnel to come to overhaul it in time.
