What is it that makes the air conditioner creak and why does the air conditioner squeak?

The buzzer sounds, indicating that the air conditioner may be faulty; The sound of refrigerant flowing may be that the air conditioner is filled with too much liquid to completely evaporate, and it may also be present when the air conditioner is turned on normally; There is something stuck on the fan blade or evaporator, such as a thread entanglement, and the fan blade makes an abnormal noise when it is running. Take it out if you can. If not, call the maintenance staff or sales company (if it is a new machine).

Workaround:1. The fan blade screw is loose or falls off, resulting in the fan blade not rotating normally.

It needs to be fixed in time. 2.The deformation caused by the unstable installation level of the bracket of the outdoor unit or the loosening of the fixing screws of the combined bracket will lead to the uneven placement of the outdoor unit of the air conditioner, resulting in a large noise during the operation of the outdoor unit of the air conditioner.

Just lay flat. 3.Generally, the noise of the air conditioner is at the air outlet of the air conditioner.

The higher the air speed of the air conditioner, the faster the air outlet of the air conditioner will run, and the noise will be amplified accordingly. Reducing the wind speed can also avoid this. 4.

The installation of indoor air conditioners and outdoor air conditioners is connected, and the connection between them will also affect the use of air conditioners and the operation of outdoor air conditioners. The indoor air conditioner installation is not stable enough, and when the outdoor air conditioner is running, the indoor air conditioner connected by copper pipes will be affected by the air conditioner compressor, resulting in the resonance of the indoor air conditioner.

There are several reasons why the air conditioner is ringing:

1. The sound of the compressor belt may be caused by the damage of the compressor belt tensioner, or it may be the sound of the compressor being faulty. This is easy to identify.

2. The sound of the blower, this is not only the sound of the air conditioner, but also the sound when the external circulation is opened, which is generally the loosening of the parts of the air conditioner.

3. The cold and warm switch in the panel, or the fault caused by the failure of the internal and external circulation motors, the sound is generally the sound made by the sound in the central control panel.

If the air conditioner squeaks, you need to maintain the air conditioner, and the method of maintaining the air conditioner is as follows:

1. Seasonal maintenance of air conditioners.

When the air conditioner is not used for a long time, in order to fully dry the inside of the air conditioner, it should first run in the air supply mode for 4 hours, add some lubricating oil to the fan motor part, then cut off the power supply, and then cover the air conditioner with an envelope, and cover the outdoor body with a protective cover to avoid sun and rain. At the same time, wipe the remote with a clean, soft, dry cloth and remove the battery. When reusing the air conditioner, it is necessary to do a basic cleaning and do an operation test.

2. In-depth maintenance of air conditioners.

Professional and technical personnel are requested to carry out comprehensive and thorough cleaning and maintenance of the core components of the air conditioner from the inside to the outside, so as to find the hidden problems of the air conditioner in time, effectively extend its service life, and be healthier and more energy-saving. The in-depth maintenance of the air conditioner is generally sufficient once every 2-3 years.

The abnormal sound of the air conditioner is generally the sound of the cooling fan, check and maintain, if it is a car air conditioner, then check the tightness of the fan belt and adjust it.

Whether it is an indoor air conditioner or a car air conditioner.

The noise of the air conditioner may be not cleaned in place, it may be that the air conditioning radiator is too dirty, and the air circulation of the internal machine is not smooth, which will also lead to the generation of air conditioning noise. Just spray the air conditioner and turn on the cooling mode, and the dirt and bacteria will be discharged along the drain. The cleaning effect is quite good, after washing, the heat sink is clean, and the noise is definitely gone.

And as long as it is cleaned once a month, it does not need to be cleaned very often.

The reasons why the air conditioner creaks are:

1. The sound of the compressor belt may be caused by the damage of the compressor belt tensioner;

2. The sound of the blower, which is not only the sound of the air conditioner, but also the sound when the external circulation is turned on;

3. The cold and warm switches in the panel or the fault caused by the failure of the internal and external circulation motors.

The above is the introduction of the reason for the crunching of the air conditioner, I hope it can help you, thank you This answer is applicable to most brands of air conditioning models such as Gree, Midea, and Haier.

1.Clean the filter screen regularly (should be cleaned once every half a month), if the filter screen is too dirty, the air inlet is blocked, not only will the internal machine be noisy, there will be vibration, the wind sound is low, and the wind speed can not be raised, and when the outdoor ambient temperature is not too low, it will make the indoor machine evaporator overheating protection and frequent standby, generally about 10 minutes; 2.Check whether the inner cover is tightly covered, sometimes the user does not cover the inner unit tightly after cleaning the filter screen or after cleaning, resulting in the vibration and sound of the air conditioner when it is working; When the air conditioner is just turned on, in order to make the room heat up (cool down) quickly, use the high-efficiency key, the indoor unit runs at high speed, the noise may be a little louder, and after working for a period of time, the air conditioner turns into normal operation, and the sound is naturally smaller; In general, the high-efficiency function will automatically stop after 15 minutes of operation.

3.When the air conditioner is just turned on, in order to make the room heat up (cool down) quickly, use the high-efficiency key, the indoor unit runs at high speed, the noise may be a little louder, and after working for a period of time, the air conditioner turns into normal operation, and the sound is naturally smaller; 4.When the air conditioner is running or after the shutdown, due to the sudden change in temperature, it may lead to the thermal expansion and contraction of the plastic shell and the internal plastic parts, and thus make a "click" sound, which is a normal situation, generally speaking, when the machine is just running, the temperature difference is too large, resulting in the phenomenon of thermal expansion and cold contraction, but when a certain expansion coefficient is reached, there will be no more clicker sound; When the machine stops running, it will make a rattle sound due to the temperature difference, which is likely to happen to all air conditioners, so you don't have to worry.

During operation, the air conditioner will emit sounds similar to running water, gas, and boiling (the sound of freon entering the indoor evaporator), which can be interpreted as the sound of refrigerant flowing in the machine and the sound of freon reflux in the machine. 5.During the operation of the air conditioner, it will emit sounds similar to running water, gas (the sound of the reversing valve reversing the direction of the machine when the pants erector is frosted in winter), and the sound of boiling the pot (the sound of freon entering the indoor evaporator), which can be interpreted as the sound of refrigerant flowing in the machine and the sound of freon reflux in the machine, which are normal sounds and not noise.

6.If the air conditioner is noisy, after eliminating the above causes of excitation, the fault is still there, you should find a professional maintenance personnel for maintenance.

1. The belt slipped. It can be used for a while, or you can directly change the belt. When turning on the air conditioner, pour some water on the air conditioner belt, if it does not sound, it is a belt problem, and it is generally loose.

2. The sound of the blower is generally that the parts of the air conditioner are loose and need to be repaired.

3. First see if the leaves have fallen, if the leaves have fallen, they will ring. If you want to clean the air conditioner, be careful that the cleaning agent enters the blower. The safety point is to disassemble the blower and see how it can be processed.

Hello, please wait for me for two minutes.

If the air conditioner is turned on, there are several reasons: First, the sound of the compressor belt may be caused by the damage of the compressor belt tensioner, or it may be the sound of the compressor malfunctioning. This noise is usually in the engine compartment.

This is easy to identify Second, the sound of the blower, this is not only the sound of the air conditioner, but also the sound when the external circulation is opened, which is generally in the glove box, and the sound is generally a clattering sound. The third is that the cold and warm switches in the panel or the fault caused by the failure of the internal and external circulation motors, the sound is generally the sound made by the sound in the central control panel. It is recommended that you go to a professional repair shop for inspection.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Causes and solutions to the noise of the air conditioner:

1.Cause of failure: The wall frame fixed hanging plate is not firm and loose or the wall is uneven.

Maintenance Method: Reset the wall panels, or treat the walls to keep the wall panels flat.

2.Cause of failure: The wall indoor fan motor and the flow turbine and fan bearing are not assembled.

Maintenance method: Adjust the assembly position of the motor, flow turbine and fan bearing of the indoor wind banquet machine.

3.Therefore, the reason for the disorder: the assembly of indoor fan motor and mobile turbine is not ideal.

Maintenance method: Separate inspection and judgment. First, remove the flow turbine, such as noise cancellation. Replacement of flow turbines (mostly due to imbalance or deformation); Otherwise, replace the internal fan motor for internal fan motor failure.

4.Cause of failure: large airflow.

Maintenance Method: The difference between high and low pressure in a refrigeration system is often uncertain. There will be a more pronounced sound of airflow, and then it will gradually become smaller and normal.

5.Cause of failure: Blockage of the air passage system.

Maintenance method: Indoor evaporator interface slag plug, replace evaporator.

Deformation of wind turbine blades. If the blades are too deformed, they will be in contact and friction with the fan shell, making a squeaky sound.

2.Compressor problems before envy. If the compressor is damaged or does not run smoothly, it will also produce relatively loud noise and vibration.

3.Bearing damage. Bearings are needed to support the various mechanical moving parts of an air conditioner, and if the bearings are damaged, they will make a squeak of metal rubbing.

4.Loose fittings. All kinds of components and accessories in the operation of the air conditioner need to be firmly installed to ensure stable operation. If it loosens or falls off, it will make a squeaky noise.

Hope it helps.

1. The sound of the buzzer means that the air conditioner may be faulty;

2. The sound of refrigerant flowing, it may be that the air conditioner is overfilled and cannot be completely evaporated, and there may also be such a sound when the normal air conditioner is started;

3. There are things stuck on the fan blades or evaporators, such as wire ties, which cause abnormal noise when the fan blades are running. If it doesn't work, please find a maintenance person, or find a sales company to talk about (if it is a new machine).

Solution: 1. The blade screw is loose or falls off, causing the blade to not rotate normally. Timely repairs are required.

2. The installation level of the bracket of the external unit is unstable or the fixing screws of the combined bracket are not tightened and the deformation is caused, which will cause the uneven placement of the external unit of the air conditioner, and the noise of the external unit of the external unit of the air conditioner will occur during the operation. Just lay it flat.

3. The first place of general air conditioning noise is at the air outlet of the air conditioner, the greater the wind speed of the air conditioner, the greater the speed of the air conditioning outlet, and its noise will be expanded accordingly. Reducing the wind speed can also avoid this.

4. The installation of the indoor unit of the air conditioner is connected with the outdoor unit, and the connection between them will also affect the use of the air conditioner and the operation of the air conditioner outdoor unit, the installation of the air conditioning indoor unit is not stable enough, and the indoor unit connected by the copper pipe will be affected by the air conditioning compressor when the air conditioner is running, resulting in the resonance of the indoor unit.

There can be many reasons why an air conditioner can creak, and here are some possible causes:

1.Dust or sharp foreign objects have accumulated inside the air conditioner, causing the air conditioner to creak when it is running.

2.The air conditioner's fan or motor is malfunctioning, causing the air conditioner to creak when it is running.

3.There is a problem with the condenser or evaporator of the air conditioner, causing the air conditioner to creak when it is running.

4.The air conditioner's pipes or connections are loose or damaged, causing the air conditioner to creak when it is running.

5.The air conditioner does not have enough or too much refrigerant, causing the air conditioner to creak when it is running.

If your aircon is creaking, it is recommended that you contact a professional aircon servicer for inspection and repair.
