What to do if there is noise when the indoor mechanism of Midea s air conditioner is cold Hanging 10

If it is the sound of flowing water, it is the flowing sound of freon, which is normal. If it's a noise, it should be called for maintenance.

There are many reasons for the sound made by the internal unit during refrigeration:

1. The wind sound of the air conditioner operation, at this time, the corresponding wind speed can be adjusted to improve the corresponding wind sound;

2. The "crackling" sound of thermal expansion and contraction of plastic parts of air conditioner cannot be completely avoided and is a normal phenomenon;

3. The sound of rapid gasification and liquefaction of refrigerant in the pipeline.

If you can't be sure of the above, please call Midea's after-sales service **4008899315 let it deal with it!

If you still have questions, you are welcome to ask questions to the company in the United States; I wish you a smooth work and a happy life!

Do you feel like the wind or the water or the resonant sound? The sound of the wind can't help it, you can't reduce it when the wind speed is lowered, the sound of water is the normal eruption of the refrigerant, the resonant sound, you can turn on the air conditioner, and after the sound comes out, gently move the indoor unit up or down, don't overforce it, see if you can reduce it? If you can, then you can look carefully to see where the sound comes from How to take the indoor unit so that there is no sound It's OK to deal with it yourself Find a maintenance person to charge you at least 50 oceans When you are at leisure, you can do it Oh, I hope you succeed.

The noise of the air conditioner may be due to the loosening of the air conditioner panel, so you can re-fix the air conditioner panel. Or the installation level of the air conditioner is unstable, and the position of the air conditioner needs to be readjusted and placed horizontally. It may also be that the motor, cross-flow rotor and fan bearing assembly of the wall-mounted room fan are not in place and need to be re-assembled.

1. Fix the air conditioning panel.

The panel is very easy to loosen when the air conditioner is used for a long time, so during operation, the vibration generated by the air conditioner causes the panels to rub against each other, resulting in noise, so it is enough to re-fix the air conditioner panel.

2. Adjust the position of the air conditioner.

The installation level of the air conditioner is unstable or the fixing screws of the combination bracket are not tightened and deformed, which may lead to uneven placement of the air conditioner, and the external air conditioner will produce noise, so it is necessary to readjust the position of the air conditioner and place it horizontally.

3. Adjust the indoor fan.

The wall-mounted indoor fan motor, cross-flow wind wheel and fan bearing assembly are not in place, which produces friction sound and makes the indoor unit of the air conditioner loud. The assembly position of the indoor fan motor, cross-flow rotor and fan bearing needs to be readjusted.

1. If the air volume of the air conditioner is adjusted to a particularly large amount, the natural sound of the indoor unit of the air conditioner is also relatively loud when the air is out, so you can appropriately adjust the air volume of the air conditioner to a little smaller, and then you will find that the noise that makes us irritable disappears.

2. The noise of the indoor unit of the air conditioner is likely to be the phenomenon of the blades being stuck, if the noise heard is a creaking sound, it generally means that there is indeed a problem with the air conditioning blades, and it is necessary to do lubrication treatment in time, and then when the air conditioner is started, it will be found that the problem of loud noise has disappeared.

3. When considering the reason for the noise of the indoor unit of the air conditioner, the installation of the indoor unit of the air conditioner should be taken into account, if the installation of the indoor unit is not stable, the air conditioner will emit shaking noise after running for a period of time, and if it is not dealt with in time, the noise will become louder and louder, so when solving the noise problem, it is necessary to check the stability of the indoor unit, and if there is indeed a problem, it is necessary to adjust it.

What to do if the air conditioner is loud.

1: When the air conditioner is noisy, you can ask the maintenance personnel to check the overall condition of the air conditioner, strengthen the vibration damping foundation of the fan, increase the silencer, check the wind wheel, bearing, and balance of the fan, and repair or replace it in time if there is damage. Reduce the air supply speed and avoid excessive wind speed adjustment when in use, which will effectively solve the noise problem of the air conditioner.

2: The air conditioner shelf is not firm, and the outdoor unit pipeline resonates, so it is recommended to adjust the external unit pipeline.

3: The sound in the corridor is louder than the outside, and the sound is close there.

The noise of the air conditioner may be caused by the loosening of the air conditioner shell, or it may be caused by the lack of oil in the motor bearing of the indoor unit fan.

Causes and treatment methods of too much noise in the indoor noise of Midea air conditioner:

1. Improper installation. When the indoor unit is running, the indoor unit connected to the copper pipe will resonate due to the influence of the compressor, resulting in a loud sound.

2. After long-term use of the air conditioner, the panel is easy to loosen, and the vibration generated by the air conditioner during operation will cause the panels to rub against each other, resulting in noise.

3. The noise value of the compressor is too large, which is also one of the most important noises of air conditioning.

4. The air conditioner radiator is too dirty, and the air circulation of the internal unit is not smooth, which also leads to increased noise.

Find a master to repair it, it may be that the axle fan motor is aging due to lack of oil, and it will be silent if you replace one.

The internal unit of Midea air conditioner is very noisy, and you can contact after-sales personnel to help repair it.

Noise is generally caused by broken parts, accessories, loose fixing, etc. It is necessary to find a professional maintenance personnel to check and find the cause of the noise to solve. FYI.

If the noise inside the air conditioner is relatively loud, then you have to ask a professional to come to the door to repair it to see if it is due to related mechanical failure or lack of oil.

Beautiful air conditioner, if the noise is very loud, you can show it and turn it up, it should be generally speaking, the noise is relatively small.

The issue is not available. If it is the noise of the wind, check whether the filter screen and air inlet are blocked by dust, and if it is mechanical noise, check whether the fan and fan are stuck.

Directly change to a low-noise one.

It may be caused by improper installation, aging of the compressor fan, or foreign objects being stuck in the compressor.

Immediately the noise is louder, and there is no way to do this, such as this person.

See if you need to repair it and see what the problem is.

There's nothing in the internal machine.,It's supposed to be a fan.,You hold on.。

You can cool the room first. When the air conditioner is first turned on, you can turn on the high wind speed gear, which runs for about 15 minutes. It feels cool and comfortable. When the room temperature gradually drops, you can adjust to a low wind speed.

When sleeping at night, some people are particularly sensitive to sound and can adjust the wind speed to automatic or low speed. On the one hand, it is not too cold to sleep at night, and on the other hand, it also reduces the noise of the machine.

When the set temperature of the air conditioner is too different from the indoor temperature, making it difficult for the air conditioner to reach the set temperature, the noise of the compressor will be greater. The main source of noise from an air conditioner is the air outlet of the air conditioner. If the air speed of the air conditioner is turned up, the noise will become louder.

Maintenance during startup:

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

The environment is poor, the weather is hot, the air conditioner is outdated, the air conditioner starts for a long time, and the number of maintenance increases when the air conditioner starts, generally once a month and a half.

Maintenance should be careful and meticulous, leaving no dead ends. Comply with the specifications, improve the refrigeration speed and effect, and achieve energy saving, freshness and comfort.

1. Fix the bracket of the outdoor unit of the air conditioner and enhance the stability of the internal unit.

2 Turn down the wind speed.

What are the causes of noisy air conditioners?

1. The installation of the external unit bracket is unstable or the screws are loose.

2. The internal unit is not installed firmly, and the rotation of the fan drives the internal unit to shake.

3. There is a problem with the compressor and the performance is aging.

You can cool down the house first, when the air conditioner is just turned on, you can turn on the high wind speed gear, about 15 minutes of running, you feel cooler and comfortable, when the room temperature gradually drops, you can change to a low wind speed gear.

When sleeping at night, some people are particularly sensitive to sound, and can adjust the wind speed to automatic or low speed, on the one hand, it will not be too cool when sleeping at night, and on the other hand, it will also reduce the noise of the machine.

When the temperature difference between the temperature set by the air conditioner and the temperature in the room is too large, it is difficult for the air conditioner to reach the set temperature, and the noise of the compressor operation will be larger. The main noise of the air conditioner** is the air outlet of the air conditioner, if the wind speed of the air conditioner is adjusted to a larger level, the noise will also become larger.

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.

Maintenance should be careful and careful, leaving no dead ends. Comply with the specifications, improve the refrigeration speed and refrigeration effect, and achieve energy saving, freshness and comfort.

A large part of the air conditioner noise comes from problems with the installation. Then there is the quality of the air conditioner. If the sound of the air conditioner running is beyond the normal range, the air conditioner manufacturer can come to identify whether there is a problem with the quality of the air conditioner.

However, this is generally rare, because the products are inspected before leaving the factory. If it is your air conditioner, there is a noise problem after use. Then it may be caused by the air conditioner's radiator being too dirty and the air circulation of the internal unit is not smooth.

For installation problems, you should directly find a professional air conditioning installation and maintenance technician to be responsible. If it is caused by the heat sink being too dirty, you can try to clean it yourself. I have been using home air conditioner disinfectant, clean it once a month, you can solve the problem, and it is very easy to use, as long as you open the cover, remove the filter, spray it evenly on the heat sink with the nozzle of the air conditioner disinfectant, and then cover the filter screen and cover the plate, open the machine to cool for a while, and the dirty things will flow away with the drain pipe.

It won't take much of your time, and don't worry about tearing it down and damaging the air conditioner. Follow-up: I haven't started using it before I can use it so loudly.

It shouldn't have anything to do with the heatsink. And I also bought two large 1 horse Midea inverter air conditioners at the same time, and there is no noise at all. It's not a normal sound, it's a very powerful "buzzing" sound.

Like the sound of a large exhaust fan in a factory. Annoying... Then what do you mean, that's new, in that case, I suggest you find the factory where you buy the air conditioner to solve it, because the home appliance is a thing, and it's difficult to judge the specific situation if you don't see something

However, their service is really amazing. Passing the buck is a lot of rhetoric. Angry.

Well, then you can find the consumer association, and if you really can't get it yourself, or if you can't use the air conditioner yourself, and you can't get it right, then they will have more to say.

Is your noise caused by engine shaking? Is it noticeable when idling? If so, then it is necessary to clean the throttle, if the throttle is dirty, it will cause the engine to shake and idle unstable, especially when the air conditioning compressor works to increase the engine load, the noise will be more obvious!

If the noise is not caused by engine shake

Workaround:1When the windshield is opened after the main engine is started, the noise of the indoor unit is normal, and when the outdoor unit is started after 3 minutes, the noise of the indoor unit increases significantly.

According to past experience, this phenomenon should be caused by secondary throttling in the refrigeration system. After the shutdown, check along the refrigerant pipeline and find that the copper pipe on the left side of the evaporator output pipe of the indoor unit is flattened. This section of copper tube was replaced, and the machine was running normally after revacuuming and filling with fluorine.

2.The machine appeared a howling sound when it was started and stopped, and it was found that it was a kind of howling sound at the capillary outlet of the outdoor unit, and it was estimated that the capillary tube was inserted into the check valve too deeply, and the check valve was impacted when throttling produced a scream. After baking with a welding torch, pull the capillary out of the single valve, readjust the insertion depth to 5 7mm, and then weld and seal, and eliminate the start-up operation.

Reasons for the noise:

1. There are sundries in the outer machine.

When the household air conditioning system is running, the debris inside the outdoor unit will rub against each other and produce noise, and the life of the air conditioner will be reduced if it is worn for a long time.

2. The installation is not standardized.

Sometimes, when installing the air conditioning system, due to the limited level of the construction team, the level of the external unit bracket, the uneven force of the screws of the outdoor unit or the unreasonable installation position of the outdoor unit are caused by problems such as the level of the external unit support, the uneven force of the outdoor unit screws or the unreasonable installation position of the outdoor unit, resulting in the collision of various parts of the system during operation and the resulting noise.

3. Compressor noise.

The compressor is one of the most important components and the "heart" of the normal operation of the whole system. The quality of the compressor directly affects the operation effect of the air conditioner, and the compressor is also the main reason for the noise generated by the external machine.

When it's cold, it still drips down the reason:

When heating and defrosting, there will be dripping at the bottom of the air conditioner, this situation is that the air conditioner will form frost on the outer unit pipeline and condenser fin when heating, and the air conditioner will automatically defrost when it reaches a certain time, and the defrosting is the outdoor opportunity to smoke is normal defrosting (this smoke is not the other smoke, do not need to call the police), do not worry, this water is not leaking, it is the air conditioning defrosting water, which is a normal phenomenon.

Due to the continuous low temperature of the weather, when the rot degree of the outdoor greenhouse is lower than 0 degrees, there will be frequent defrosting, and the general air conditioner will defrost once every 45 minutes, and the defrosting time will be about 10-15 minutes each time, and the defrosting time in rainy and snowy weather is more frequent, which is a normal phenomenon.
