The air conditioner is buzzing loudly, what is the matter with the buzzing of the air conditioner s

The reason for the humming sound of the indoor unit of the air conditioner may be the resonance caused by the loosening of the indoor cover when the air conditioner is working, and it should be solved by closing the cover again. Air conditioning noise is the noise emitted by the air conditioning system when it is working, including the noise generated by the fan escaping into the room, the regenerative noise at the end of the air duct, the noise generated by the fan, the modulated noise and the random noise caused by the vortex when the blades rotate against the surrounding air. Air Conditioner Noise Treatment Method:

1. The compressor emits abnormal vibration and noise. The compressor base uses a spring vibration isolation structure, and the user should first pull out the chassis and relax the nut before installing the air conditioner, so that the spring can play a vibration isolation role during the operation of the compressor and reduce its vibration and noise. There are also a small number of compressor internal parts touching the shell, when running, there is an intermittent metal knocking sound, and when this fault is encountered, it can only be repaired by opening the shell.

2. The air conditioner emits other crashing sounds. During the operation of the air conditioner, the fan set screw is loose, which causes the fan to shift and generate noise. If the chassis rigidity is poor or the fan motor is not adjusted well during the installation process, and this fault is encountered, the chassis can be withdrawn, and the installation position of the fan motor can be readjusted until it is not touched, and then it can be tightened.

Reasons and solutions for a large buzzing sound when the air conditioner hangs up and turns it on:

1. The speed of the external fan is not as good as before, and the poor heat dissipation makes the compressor over-temperature and overcurrent, causing it to feel buzzing after start-up. After a short time of powering on, the overcurrent protector will act, and the sound will be quieter. If this is the case, there is a problem with the capacitance of the fan, and the situation will improve if you change the speed to a new speed.

2. If "the outdoor fan rotates normally", it may also be due to the poor heat dissipation and high exhaust pressure caused by the dirty condenser of the external unit, which makes the machine running sound heavy (loud); After running for a while, the heat exchange medium circulates for several cycles to disperse the hot gas, and the machine tends to normal. If this is the case, just remove the dust from the condenser.

Maintenance during start-up:

After the air conditioner is turned on, the maintenance times during the air conditioner start-up process are determined by many factors such as environmental conditions, climatic conditions, number of hours of start-up, surrounding dust, air cleanliness, and whether the room is clean.

The environmental conditions are not good, the weather is hot, the air conditioner is outdated, the air conditioner is turned on for a long time, and the number of maintenance during the air conditioner start-up process increases, usually once every month and a half.

If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, the air conditioner is turned on reasonably, and the electric fan is used alternately, the maintenance cycle can be appropriately extended, from the start of the air conditioner to the shutdown of the air conditioner for maintenance 1-2 times.

Hello, glad to be able to your question. The reasons and solutions for the buzzing of the indoor unit of the air conditioner are as follows: 1. Installation problems.

Specific reasons: the indoor unit is not tightened, resulting in resonance between the body and the wallboard; The air filter is not jammed. Second, the reason for the machine itself.

Specific reasons: caused by the deviation of the center of gravity of the cross-flow fan; cracked inner fan; Caused by poor bending bearings of motor skins, there is AC sound; Transformer AC sound. 3. The reason for external stuffiness may be the structural problem of the wall, and if it is installed on a hollow wall, there will also be abnormal noise.

Fourth, the filter screen is too dirty, and the air inlet is blocked, which will not only make the internal machine noisy. Maintenance method for the buzzing sound of the air conditioner: First check whether the indoor unit is hung tightly, the filter screen is stuck, confirm that everything is normal, and then listen carefully to this sound, it is suspected that it is the AC sound of the internal fan motor, but after replacing the new fan motor, there is still a humming sound, and the phenomenon is still the same, replacing the transformer is also useless, inadvertently, when I touch the online pipe and find that there is a slight vibration, I hold down the wall side to listen, and the instantaneous sound is nothing, only to find that it is the user's hollow wall that causes the wall and the pipeline to resonate.

Resonate, adjust.

The reasons may be:

1. When the air conditioner starts or stops, it is normal for the plastic parts of the inner machine 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 to cause resonance, so don't be too anxious at this time.

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, the refrigerant in the system will make a loud flow sound before reaching the equilibrium, which is a normal phenomenon.

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, and the distance between the fan and the outer wall should be adjusted 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 smoothly.

7. Resonance occurs due to the aging of the compressor gasket because the gasket hardens, or the compressor itself is noisy (this possibility is very small).

1.The noise of the indoor unit is mainly caused by the infirm installation of the indoor unit, the resonance or the indoor extension is not fixed firmly, or the locking screws of the cross-flow fan blade and motor shaft are loose.

2.Gently push each part of the air conditioner with your hand to see if the noise of the indoor unit is reduced or absent. If there is still one, remove the inner shell to observe whether the indoor extension motor is firmly fixed, whether the through-flow fan blade has axial channeling, if so, please fasten.

3.If the noise is obvious and the whistling sound is harsh, then the motor bearing of the fan is damaged and the motor bearing needs to be replaced.

The buzzing sound of the indoor unit of the air conditioner is caused by the vibration caused by the poor heat dissipation and imbalance of the outdoor unit caused by excessive dust accumulation on the radiator fins and fan blades of the air conditioner for a long time.

Solution: After the power is off, the water pipe is connected to the water to flush, and the water will be used after the water is dry.

Find a manufacturer or professional to check and clean it.

How to maintain the air conditioner:

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.

In-depth maintenance of the air conditioner.

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.

Five taboos for the use of air conditioners:

Keep doors and windows closed for a long time.

Tightly closed doors and windows should not rely on air conditioning to raise and lower the temperature for a long time, and windows should be disconnected for ventilation to maintain indoor air circulation and avoid lack of fresh air.

Lack of ventilation equipment.

The installation of an air conditioner and a ventilator can deliver a large amount of filtered fresh air to the air-conditioned room.

There is a large temperature difference between indoor and outdoor.

In summer, do not adjust the indoor temperature too low, the temperature difference between indoor and outdoor is 5 8.

The equipment is not cleaned frequently.

The air conditioner and dehumidification device should be checked and cleaned regularly, especially the filter screen should be cleaned on time, so that it can really play the role of filtering dust, germs and harmful gases.

The temperature setting is too low.

During daily use, do not set the temperature too low, so as not to affect the service life of the air conditioner in a high-speed operation state for a long time. It is best to set it in automatic mode, which can not only cool down quickly, but also save electricity.

The air conditioner buzzes loudly, it may be that the air volume of the air conditioner is turned on too much, and the remote control can be adjusted to silent mode to reduce the wind speed and noise. It may also be due to the fact that the air conditioner has been used for too long, and the blades of the internal unit are jammed. If the internal unit of the air conditioner is shaking during operation, it is necessary to fix the internal unit in time.

The solution to the loud humming sound of the air conditioner

If the air conditioner is not installed smoothly, the air conditioner will shake when it is running, and the air conditioner needs to be fixed in this case. It is recommended to contact the after-sales personnel of the air conditioner and arrange a professional master to come to the repair.

1. There is noise in the air conditioner.

In the production process of some air conditioners, poor materials, production line employees cut corners, quality inspectors work sloppily, etc., may cause quality problems, and similarly, in the process of transportation and handling, there may also be quality damage. Some household air conditioners have very high requirements for packaging protection, and the packaging box has a tight foam for filling and fixing, so the probability of noise is relatively small.

2. Why is there noise in the air conditioner?

1. Failure to clean in time.

Long-term use of air conditioners, if they are not cleaned, will cause dust to accumulate on the air conditioner radiators, which will inevitably affect the operation of the air conditioner and bring a series of problems. For example, the heat dissipation is blocked, the air circulation of the internal unit is not normal, and so on. Problems caused by the accumulation of dust on the radiators will cause the operation of the air conditioner to produce noise.

2. Quality is the key.

If the air conditioner produces noise during operation, one of the important reasons is that the air conditioner itself has quality problems. In this case, noise is inevitable in the operation of the air conditioner.

3. The design and installation are too sloppy.

When some air conditioners are installed, they often choose the "full ceiling" installation. This is not only for the aesthetic aspects of the installation, but also for the sake of reducing the noise generated during the operation of the air conditioner. However, many air conditioner designers and installers do not design well or design well but do not install it well due to the technical problems of the installers in the process of installing air conditioners, so that the air conditioner produces noise during operation.

4. Compressor quality problems.

The compressor is the heart of the air conditioner, the quality of the compressor directly determines the noise of the air conditioner, and the quality of the compressor directly controls the use effect of the air conditioner. The noise generated during the operation of the noise air conditioner is mainly generated by the internal evaporator and the external condenser.

1.Air conditioning outlet: The main noise of the air conditioner is the air outlet of the air conditioner, when the air conditioner turns on the wind speed, the noise value of the air conditioner will of course gradually increase, which is one of the main noise values of the air conditioner;

2.Loosening of the air conditioner panelLoosening of the air conditioner panel: When the air conditioner is used for a long time, the panel of the air conditioner is easy to loosen due to various reasons.

3.Installation of the indoor unit of the air conditioner: 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 internal fan is probably the biggest if it is broken.

1. 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.

2. 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.

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

4. 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.

The air conditioner is buzzing in the room, which may be the sound of you only being able to flow air, just like the sound of a refrigerator, which is normal.

Hello, about your question, I think the noise after the air conditioner starts is mainly the working noise of the compressor, and it does not belong to the fault. Because the compressor works intermittently and is not always working, it will make a loud working noise when it is started again. If the key door is opened, the automatic operation of the air conditioner is definitely abnormal, and most of the cases are the failure of the fan control module, and new accessories need to be replaced.

Extended information: air conditioning noise analysis: 1. Whether the filter is cleaned regularly (should be cleaned once a week), if the filter is too dirty, the air inlet is blocked, which will not only make the internal machine noisy, vibrate, 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 unit evaporator overheating protection and frequent standby, generally about 10 minutes.

2. 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 a loud vibration of the indoor unit of the air conditioner during work. 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 bigger, and after working for a period of time, the air conditioner will turn into normal operation, and the sound will naturally be smaller; In general, the high-efficiency function will automatically stop after 15 minutes of operation. 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 therefore make a "click" sound, which is a normal situation. 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.
