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

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.

There are many reasons why the air conditioner is loud, and there are different solutions for different reasons.

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 inner unit to expand and contract due to the change in temperature. There are also some pipelines that are deformed due to thermal expansion and contraction, which are attached to the compressor or metal shell, causing resonance, so there is a rumbling sound.

2.Whether the fixed wall of the internal and external machine is strong, and the loosening or deformation of the wall fixing screw is also 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.When the air conditioner is started or shut down, it is normal for the refrigerant in the system to make a loud flowing sound before reaching equilibrium.

5.It may be caused by the outdoor unit being too dirty, and it can be solved by cleaning it with water after the power is off.

6.When the fan is running, rub against the outer wall, adjust the distance between the fan and the outer wall in time. In addition, it is also possible that the fan is stuck, add a little lubricating oil to the air conditioner fan shaft and let the fan rotate comfortably to solve the problem.

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.

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.

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

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

The copper tube is connected to the indoor chassis and because it is not fixed, it resonates.

The noise level of the compressor is relatively large during operation, which will also affect the air conditioner and make 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.

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.
