The air conditioner outside the unit, the rumbling sound is very loud, what s going on?

From the look is the following reasons:

1.When the air conditioner is started or stopped, it is normal for the plastic parts of the internal unit to make a sound due to the expansion and contraction of the internal unit due to temperature changes. There are also some pipes that expand and contract due to thermal expansion.

This causes deformation to stick to the compressor or metal housing, causing resonance.

2.Whether the fixed wall of the internal and external machine is strong, and the loose or deformed wall fixing screws are easy to lead to this situation.

3.Check whether the indoor and outdoor connecting pipes are fixed and whether there is any collision with the outdoor unit or other objects.

4.Refrigerant in the system when the air conditioner is started or shut down.

It is normal to make a loud flowing sound before equilibrium is reached.

5.If the outdoor unit is too dirty, clean it with water after the power is off.

6.When the fan is running, it rubs against the outer wall, so adjust the distance between the fan and the outer wall in time. Alternatively, it is also possible that the fan is stuck and is given to the air conditioner fan.

Add some lubricating oil to the shaft to ensure that the fan rotates smoothly.

7.It is unlikely that the compressor gasket will resonate due to the aging of the gasket due to the stiffening of the gasket, or that the compressor itself will be noisy.

1. The wind speed of the air conditioner is relatively large, so the sound of its external unit will gradually become louder, which is normal.

2. The panel of the air conditioner is loose, and there will be a lot of vibration when it is running.

3. The copper tube is connected to the indoor chassis, because it is not fixed, which will produce resonance.

Most of them are the sound of the external fan, which may be caused by loose screws or deformed covers. Check it out, the effect of the air conditioner without a fan will be greatly reduced.

The rumbling sound of the air conditioner's outdoor unit is very loud, which may be caused by the fan blades not being fixed firmly. It may be that the outer cover of the external unit is blocking the fan blades.

The air conditioner is very loud, and its rumbling sound should be a problem with his compressor and its bad shock absorbing pads.

The rumbling sound of the air conditioner is very loud, you can check whether the installation is firm, if the installation is firm, it can only be the quality of the air conditioner itself.

There are many reasons why the air conditioner is very loud, and one of the most important reasons is that the stability of the indoor unit installation is relatively poor. When the personnel transfer the air conditioner to the external unit, his copper pipe is connected to the indoor unit, and if the indoor unit is not stable at this time, then it will be affected by the compressor in it. In the case of charging, the outdoor unit produces a loud sound.

If the stability is very weak, when the propeller rotates, not only will it produce a very loud sound, but it will also leak. <>

The second reason is that the air conditioner itself can produce some noise, but it is only a matter of the noise level. Some air conditioners with better quality can produce noise that can be suppressed by their built-in compressors. It uses a converter to convert a higher noise into a lower sound, so that it doesn't make a lot of noise.

The air conditioning noise is generally the air outlet of the air conditioner, and the wind speed of the air conditioner is too large in the case of human intervention, and the panel of the air conditioner will not be able to close tightly. At the same time, the noise of the air conditioner gradually becomes louder. <>

There is also a very small reason is the aging of the air conditioner, in this case, most air conditioners will have nothing to do with the bad of ***. You must know that every air conditioner has a certain number of parts, and after a certain number of years, there will be some deformation of each part of the air conditioner. For example, there will be some different degrees of wear and tear inside the compressor, which will also make the panel of the air conditioner wear and tear, reduce its quality, and the noise will become larger.

Of course, the most radical way in this case is to replace the air conditioner with a new one, and if it is remediated in time, it is not a solution. <>

There is also a situation where noise can also be generated when the installation of personnel is not standardized. Personnel may not stabilize its air conditioning feet and brackets are not firmly fixed and the installation level of the external unit is not up to standard. Of course, it is not excluded that the personnel did not adjust the frequency of the external machine to the appropriate position.

If it can't be tuned to the right position, then the noise can't be ruled out. At the same time, when in use, the air conditioner will produce some subtle vibrations during operation, which will also cause the collision of internal parts and make noise.

The air conditioner is very loud, I think this is more normal, because the current air conditioner has this problem, and the only way to solve this problem is to use the vertical cabinet type.

There are several reasons, the first is that the air outlet of the air conditioner is blocked, the main noise of the external unit is the air outlet of the air conditioner, when the air outlet of the air conditioner is blocked by dust, the noise value of the air conditioner will gradually increase; The second is the loosening of the air conditioning panel, after long-term use of the air conditioner, the air conditioning panel is easy to loosen due to various reasons, so that the vibration generated by the air conditioner during operation will make the panels rub against each other, resulting in noise; The third is the noise emitted by the operation of the air-conditioning compressor, the air-conditioning compressor is also one of the most important air-conditioning noises, the noise value of the compressor is too large, and it will also affect the use and rest of our normal users.

It may be because the wind speed of the air conditioner is too large, which causes the noise of the air conditioner to become louder, or it may be because the air conditioner is old and the performance is not stable enough, so the noise is caused.

The reasons why the air conditioner roars so loudly are as follows:First, it may be that the installation of the air conditioner is not standardized, the feet and brackets are not fixed firmly enough when the air conditioner is installed, the installation of the external unit is not stable enough, and the external machine vibrates when it is working, and it will make some noise. In this case, it is only necessary to reinforce the various parts of the external unit and place the external unit in a stable place.

Second, in the process of using the air conditioner, due to the collision and friction at the junction of each other, the vibration causes noise. In this case, first determine the cause of the failure, and then prescribe the right medicine. If the panel is loose and caused by local friction, the panel needs to be reinforced.

Third, air conditioning compressors.

The compressor is an important component of the air conditioner, the compressor noise may generally be caused by vibration, in addition to the damage of the compressor parts, the poor performance of the compressor aging will also lead to loud noise, humming problems. In this case, it is necessary to adjust the spacing of the external machine pipeline, replace the damaged parts in time, install a shock-absorbing platform, shock-absorbing cement, and wrap soundproof cotton.

soundproof cover to solve.

1. The air conditioning wind speed is large, the noise of the air conditioning outdoor unit is relatively large, the main ** is the air conditioning outlet, when the air rubber is turned on more and more, the noise value of the air conditioning will slowly increase, which is also one of the main sounds we hear from the air conditioning outdoor unit**, which is generally unavoidable, but under normal circumstances it will not affect the rest of the person or others.

2. The air conditioning panel is loose, in the process of long-term use of the air conditioner, the air conditioning panel is easy to show signs of loosening due to various reasons, which will cause the air conditioner to vibrate in the process of operation and make the panels rub against each other, so that the sound is relatively loud, it is recommended to repair it in time so as not to affect the normal use.

3. The installation is unstable, when we install the air conditioner, the installation of the indoor unit is connected to the outdoor unit, if the installation of the indoor unit is not stable enough, when the air conditioner starts to run, the outdoor unit connected by the copper pipe will also be affected, resulting in resonance, which is also to find a special maintenance personnel to repair.

Some brands of air conditioners are like this, the sound of the external unit is very loud, but the installation position and installation method are also the same, it may also cause the noise of the external unit, mainly to see if it was used before, suddenly the noise is loud, if this is the case, it is recommended to report for repair directly.

Under normal circumstances, if the external unit of the air conditioner rumbles loudly, it should be that the screws that fix the external unit are loose, which will produce this effect. You can check to tighten the screws.

The external unit of the air conditioner is the compressor, cooling fan and condenser. See if it's fixed. Either the compressor is faulty.

Hello! The air conditioner is loud, and the first thing to exclude is the sound of the compressor, which should be the resonance of the shell caused by the fan turning.

If it's a constant rumbling sound, it may be that the fan blades have scraped something else. Or the bearing is damaged. It could also be that one of the screws is loose. Hope.

Something should be wrapped around the fan, or it could be a sound caused by a broken bearing.

The air conditioner outside the unit, the rumbling sound is very loud, what's going on? I think the air conditioner is very loud, probably because the screws of this external unit are loose.

It may be that the compressor is broken, so the noise is a bit loud.

If the air conditioner outdoor unit is very loud, at this time I think it should be maintained, if you do not maintain, it will affect the neighbors, this is very troublesome, so you should find his after-sales service, let him go to show you what the reason is.

This can only be checked by professional personnel to determine the cause, not the problem of the compressor. It's a matter of heat dissipation.

1. The air speed of the air conditioner is large, the noise of the air conditioner is relatively large, the main ** is the air conditioning outlet, when the air conditioner turns on the wind speed more and more, the noise value of the air conditioner will slowly increase, which is also one of the main sounds we hear the air conditioner outside, which is generally unavoidable, but under normal circumstances it will not affect the rest of the person or others. 2. The panel of the air conditioner is loose, in the process of long-term use of the air conditioner, the panel of the air conditioner is easy to show signs of looseness due to various reasons, which will cause the air conditioner to vibrate in the process of operation and let the panels rub against each other, so that the sound is relatively loud, it is recommended to repair it in time so as not to affect the normal use. 3. The installation is unstable, when we install the air conditioner, the installation of the indoor unit is connected to the outdoor unit, if the installation of the indoor unit is not stable enough, when the air conditioner starts to run, the outdoor unit connected by the copper pipe will also be affected, resulting in resonance, which is also to find a special maintenance personnel to repair.

If your air conditioner is rumbling very loudly, it must be your compressor that is out of order. Generally, we can't repair it ourselves, so it's best to find a professional to repair the compressor for you.

The rumbling sound of the air conditioner outside the unit is very loud, consider whether it is a loud sound of the compressor? Either the exhaust fan bearing is broken, you can find a professional to take a look, you can find a professional to take a look.

It may be that the air conditioner is unstable and has side vibrations, so it will rumble loudly.

If there is a rumbling sound outside, it must be of poor quality, and it is recommended that you find a relevant professional to take a look.

Loosening of the air conditioning panels. When the air conditioner is used for a long time, the panel of the air conditioner is easy to loosen due to various reasons, so that the vibration generated by the air conditioner during operation will make the panels rub against each other, resulting in noise.

The noise caused by non-standard installation is commonly loosened feet, unstable bracket fixing parts and uneven installation of external units.

If the quality of an air conditioner is unqualified, the sound of the air conditioner will be very loud, and the sound will be very loud when it is refrigerated.

Another is that the machine is aging, which will also cause a lot of noise.

When the air conditioner is working, the sound is very loud, first of all, the air conditioner is cleaned up, some of the sound is caused by vibration, and the four corners of the air conditioner are installed at the four corners of the air conditioner, which will effectively avoid the sound of the air conditioner when the outside unit is working.

The sound of the air conditioner will be very loud, and the sound will be very loud when it is cooling.

Another is that the machine is aging, which will also cause a lot of noise.

There are a variety of reasons that may cause this situation, such as the lack of oil in the outdoor unit fan, the loose compressor base, and the poor installation of the external unit, which will cause this kind of sound, and should be checked and repaired in time to avoid greater losses.

The rumbling sound of the air conditioner outside the unit is very loud, probably because there is a problem with the compressor, you can call a professional master to come to take a look.

Hello! Judging from your description, there should be a problem with the fan bearing of the outdoor unit

Loose fixation, old machine, will increase the noise.
