What s going on with the loud buzzing of the air conditioner

1.It may be a collision of the copper pipe inside the external machine. 2.

Compressor collides with copper pipe3The bracket used to secure the compressor underneath is loose. You can see this place from underneath the external machine.

4.Damage to the inside of the compressor 5The shaft of the fan is broken.

The noise of the outdoor unit mainly comes from the loose fan blades of the outdoor unit, the loose compressor, and the dust falling of the fan blades (eccentric fan blades). Generally, the noise** is identified before making a decision. Tighten the loose ones and clean up the fallen ash.

If there is noise inside the compressor, the compressor can only be replaced, otherwise it will be used.

It may be because the blades of the fan are broken, and the fan will be very loud; It may be a compressor problem, the screws are loose, causing the shell and the press to stick together, causing vibration and noise; It may be the noise caused by the non-standard installation of the external unit, and the common ones are loose feet, unstable brackets, and uneven installation of the external unit. Solution: 1. After the power is off, disassemble the outer shell of the air conditioner, check the fan blade, and if a fault is found, ask a professional to replace the fan blade.

2. Generally, adjust the spacing between the external machine pipelines to eliminate the fault. 3. Eliminate it by adjusting and replacing the shock-absorbing rubber pad at the foot of the press, wrapping soundproof cotton, etc. Place a counterweight of appropriate weight and size on the outdoor unit of the air conditioner to change the natural frequency of the vibration of the air conditioner.

Knowledge expansion: air conditioner maintenance method 1, air conditioner that is not used for a long time, not only to disconnect the power supply of the air conditioner, but also to unplug the air conditioner, otherwise it will also damage the air conditioner. 2. Clean the outdoor and indoor units of the air conditioner regularly, otherwise it will not only affect the use of the air conditioner, but also increase power consumption.

3. The dust of the indoor unit of the air conditioner should also be wiped in time, and the accumulation of more dust on the indoor unit will also affect the function of the air conditioner.

Too much fluorine, poor heat dissipation or too dirty causes heavy compressor load.

The air conditioner outside the unit is loud and buzzing Solution:

1. Tighten the panel:

The noise of the air conditioner can be solved by tightening the air conditioning panel, because the noise of the air conditioner may be due to the loosening of the panel, so that when the air conditioner is running, it is easy to collide with the wall and make noise, so at this time, the air conditioning panel can be tightened in time.

2. Install the outdoor unit correctly

The noise of the air conditioner may be due to improper installation of the air conditioner, the phenomenon of tilting, or the distance between the air conditioner and the wall is too close, pay attention to the installation of the air conditioner, remind the master to place the outside unit smoothly and keep a certain distance from the wall.

3. Replace the compression machine

When the air conditioning compressor is aging, the air conditioner runs slowly, the parts wear and tear produces noise, and the compressor itself will also make noise.

Pay attention to the heating of the air conditioner:

1. Pay attention to cleaning the vents.

In summer, air conditioners are generally mainly used for refrigeration, and then in autumn, they are basically not started, and at this time, more dust will accumulate in the vents. Therefore, before using the heating function for the first time in winter, it is necessary to clean the vent of the air conditioner, and it is best to remove the filter and clean it, so as to ensure that the hot air blown by the air conditioner is clean.

After the air conditioner is cleaned, it cannot be used immediately to prevent moisture inside, which will cause the internal wiring to burn out. Even if it is dry, do not turn on the heating mode immediately after connecting the power supply, because the air conditioner has not been used for a long time, it will enter the state of sleep protection, and you need to turn on the power supply of the air conditioner for an hour or two before heating.

2. Pay attention to the temperature setting.

Although it is said that the indoor temperature can be adjusted to 30 degrees in winter, it is very warm, but it is also unhealthy, because the temperature difference between indoor and outdoor is too large.

The noise of the air conditioner outside unit is loud and humming, indicating that the inside of the air conditioner may be slippery and malfunctioning. It may be due to damage to the mechanical parts inside the air conditioner, or due to a problem with the electrical circuits inside the air conditioner. If the air conditioner is noisy and humming, you should first check whether the external unit is in contact with foreign objects, or whether there is friction between the external unit and the external environment.

If there is, it should be dealt with immediately to avoid delaying the failure of the air conditioner. Secondly, it is necessary to check whether the insulation of the air conditioner is worn, and if so, replace it in time so as not to affect the use of the air conditioner. At the same time, it is necessary to check the circuit of the air conditioner's external unit, whether there are problems such as poor contact, open circuit, short circuit, etc., and if so, it should be dealt with in time so as not to affect the normal use of the air conditioner.

In addition, it is also necessary to check whether the mechanical parts of the air conditioner are loose, damaged or leaked, and if so, they should be dealt with in time so as not to affect the normal use of the air conditioner. In short, the outdoor unit of the air conditioner is noisy and humming, which needs to be checked in time and effectively treated, so as not to affect the normal use of the air conditioner and prolong the service life of the air conditioner.

The reason why the air conditioner has been buzzing outside the unit and how to fix it.

When the newly bought air conditioner first started, it must have a good use effect, and there will be no noise and other problems, and we are very comfortable to use. But after using it for a period of time, the air conditioner will inevitably have some such and such fault problems that affect our use, and the noise of the air conditioner is one of them, what should we do, let's introduce it below.

1. The reason for the loud noise of the air conditioner.

1. Air conditioning outlet.

The main noise of the air conditioner is the air outlet of the air conditioner, when the air conditioner is turned on, the greater the wind speed, the noise value of the air conditioner will gradually increase, which is one of the main noise values of the air conditioner.

2. Loosening of the air conditioning panel.

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.

3. Installation of air conditioning indoor unit.

The installation of the indoor unit of the air conditioner and the connection of the outdoor unit also affect the timing, use and noise of the air conditioner. If the installation of the indoor unit is not stable enough, when the outdoor unit is running, the copper pipe is connected to the indoor unit, and the indoor unit is not stable enough, it will be affected by the compressor, resulting in the resonance of the indoor unit.

4. Air conditioning compressor.

Air conditioning compressor This is also one of the most important air conditioning noise, the noise value of the compressor is too large, which will also affect the use and rest of our normal users.

Second, the solution to the high noise of the air conditioner.

1. The noise caused by non-standard installation is common such as loose feet, unstable fixing parts of the bracket and uneven installation of the external machine. The noise caused by such factors is generally tightened to the external unit, and the noise can be discharged by leveling.

2. The outer casing is loose and causes the joint to collide with each other and vibrate during work to produce noise, and the fault part is judged first and then fastened.

3. The vibration of the press during work causes the collision noise between the external machine pipelines, and the fault can be eliminated by adjusting the mutual protection distance between the external machine pipelines or installing shock-absorbing cement. Noise when the press is working: one is caused by parts.

It is common to see a press jam or a damaged starting capacitor of the press. Damaged spare parts can be replaced. The other is that the performance of the press is poor, and it produces a low-frequency vibration hum when working.

It can be eliminated by adjusting and replacing the shock-absorbing rubber pad of the press foot, wrapping soundproof cotton, etc.

The buzzing of the air conditioner may be caused by the blockage of the radiator caused by the air conditioner outside the model, the damage of the fan bearing, and the burning of the motor winding. Blockage of the radiator will lead to a decrease in the heat dissipation efficiency of the air conditioner, which will make the air conditioner make a humming sound; Damage to the fan bearing will cause the fan to fail to function properly, which will cause the air conditioner to hum outside; Burned out motor windings can cause the motor to not work properly, causing the air conditioner to hum.

See if it's one of the following reasons:

1.When the air conditioner starts or stops, it is normal for the plastic parts of the inner unit to expand and contract due to temperature changes. There are also some pipelines that are deformed due to thermal expansion and contraction, and are attached to the compressor or metal shell, 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.When the air conditioner is started or stopped, it is normal for the refrigerant in the system to make a loud flow sound before reaching equilibrium.

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. In addition, it is also possible that the fan is stuck, add some lubricating oil to the fan shaft of the air conditioner to ensure that the fan rotates comfortably.

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