■Why refrigerators are noisy
We use refrigerators every day, but the cooling mechanism to keep food fresh A lot of parts are used, and there are various causes of noisy sound depending on the failure of those parts. In addition, abnormal noise is also generated due to deterioration over time and defects in the installation location. We will explain in detail the possible causes.©︎https://www.photo-ac.com/
・Compressor for low sounds
A compressor is a device that compresses the refrigerant that cools the refrigerator, and is installed outside the refrigerator to release heat during compression. A low "boom" sound is heard at regular intervals when the compressor operates. If this low-pitched sound continues to ring, the sound gets louder, or it continues to vibrate finely, it may be malfunctioning or out of order.©︎https://www.photo-ac.com/
・If you want to stop by opening the door, use the fan
The refrigerator fan is the part that operates the longest because it spreads cold air to maintain the temperature inside the refrigerator. Therefore, it is a part that is prone to deterioration over time, but it may make a rattling sound when it hits something in the refrigerator. It works when the door is closed, so it stops when you open it. If you open the refrigerator and it becomes quiet, you can be sure that the fan is the culprit.©︎https://www.photo-ac.com/
・Thermostat failure
The thermostat is a temperature sensor that is used to optimize the temperature inside the refrigerator. If the thermostat fails, it will not be possible to measure the temperature inside the refrigerator, which will also affect the fan. If it senses that the temperature is rising, the fan will continue to rotate to lower the temperature inside the refrigerator, causing abnormal noise.©︎https://www.photo-ac.com/
・Frost removal device failure
If you leave the refrigerator open or open and close it many times in a short period of time, frost will form. Also, if you pack too much food into the refrigerator, moisture will come out of the food, causing frost to form inside the refrigerator. The defrosting device removes the frost, but if it breaks down, the frost builds up and hits the fan, causing a rattling noise.©︎https://www.photo-ac.com/
・Damage of the damping material
The damping material is a rubber device that reduces noise such as the vibration and sound of the compressor. If this damping material is damaged, the noise from the compressor, which was normally suppressed, can be heard directly through the floor, etc., causing a loud noise that can be heard in the next room. If you feel a large vibration or noise, you may want to suspect a failure of the damping material.©︎https://www.photo-ac.com/
・The refrigerator is touching the wall
If the refrigerator is touching the wall, the vibration and sound of the compressor and fan on the back of the refrigerator will be transmitted through the wall and make a loud noise. you may end up Check the installation location of the refrigerator and make sure it is installed away from the wall. The distance between the sides of the refrigerator and the wall must be at least 1 cm on the left and right, and the distance between the top of the refrigerator and the ceiling must be at least 5 cm. If removing the refrigerator doesn't help, check to see if the outlet is bent and touching. Even if the refrigerator is away from the wall, it may make an abnormal noise if it is hit by an electrical outlet.©︎https://www.photo-ac.com/
・Refrigerator lifespan
There are various opinions about the lifespan of a refrigerator, but it is said to be about 10 years. If it has been more than 10 years since purchase, it may be a failure due to aging and may be at the end of its life. Some people have used old refrigerators for more than 10 years, so it depends on how often you use them and how often you open and close them.©︎https://www.photo-ac.com/
■What to do when the refrigerator is noisy
We have introduced the causes of abnormal noises in the refrigerator. If you can confirm the cause, please try it.©︎https://www.photo-ac.com/
・Check where the sound is coming from
To find out the cause, let's first check where the sound is coming from. If you feel the vibration or sound at regular intervals is loud, there may be a problem with the installation location. If you hear a constant low noise coming from outside the refrigerator it's the compressor, if it shuts off when you open the refrigerator it's the fan. If there is a strong vibration or a fairly loud sound, the damping material may be damaged.©︎https://www.photo-ac.com/
・Do not place objects on or around the refrigerator
If you place objects on or around the refrigerator, it will block the heat dissipation, which may cause the refrigerator to not cool properly and may lead to malfunctions, resulting in poor cooling. And the extra electricity bill will also take. Also, if you place the cupboard next to the refrigerator, the tableware may resonate with vibrations and cause noise. Placing items on top of the refrigerator is convenient and makes effective use of space, but it is better not to place items on top of the refrigerator as it may lead to malfunctions. If it is absolutely necessary to place the cupboard next to the refrigerator for reasons such as space, you can reduce the shaking by stretching the ceiling and the cupboard with a tension rod for earthquake countermeasures.©︎https://www.photo-ac.com/
・Cleaning around and inside the refrigerator
When dust accumulates around the refrigerator, the space for releasing heat from the compressor decreases, causing abnormal noise. Dust tends to accumulate under the refrigerator, so remove it with a broom or the like. If it has casters, it may be quicker to move it and clean it. If the inside of the refrigerator is too dirty, it may affect the cold air outlet, so keep it clean.©︎https://www.photo-ac.com/
The dirt in the refrigerator is hardened by the cold air, but if you put baking soda water dissolved in hot water in a spray bottle and use it to wipe it off, the dirt will come off easily and it will also have a deodorizing effect. Clean with a clean cloth, as cleaning with a worn-out cloth will rub in germs. If the rubber packing is clogged with dirt, the refrigerator will not close properly, causing the temperature inside the refrigerator to rise and frost to form. Clean it up with baking soda spray. It is convenient to use a cotton swab for fine details. After cleaning with the baking soda spray, wipe it off with a clean, dry cloth.©︎https://www.photo-ac.com/
・Defrost
Refrigerators that do not have an automatic defrost function must be defrosted. If you leave it alone, the frost will grow and you will have to turn off the refrigerator to melt the frost. Remove frost as often as possible when it reaches 1 cm or more.©︎https://www.photo-ac.com/
Take out the food in the freezer once and put a wooden spatula in the gap between the refrigerator and the frost. If it does not come off easily, apply a little wind from the dryer to make it easier to remove. After removing everything, wipe it off with a dry towel.©︎https://www.photo-ac.com/
・Replacing the fan
Fan parts are sold online. If you look at the model number of your refrigerator and find the corresponding fan on sale, you can replace it yourself. How to exchange is introduced in blogs and videos on the Internet. However, since it is necessary to disassemble the inside and install parts, it may take a long time or fail if you are not used to it. If you are uneasy or troublesome, it is faster to ask the trader to replace it. If you know that the fan is definitely broken and you are good at handling machines, it may be a good idea to try.©︎https://www.photo-ac.com/
・Use anti-vibration sheets and anti-vibration mats
If you are concerned about the vibration noise of the refrigerator, it is recommended to use anti-vibration sheets or anti-vibration mats under the legs of the refrigerator. is. It is easily available at mail-order sales and home centers, so if you are concerned about the noise of a refrigerator that is not malfunctioning, please try it.©︎https://www.photo-ac.com/
Another way is to raise the fridge. If you raise the height, the refrigerator does not touch the ground directly, so you can reduce the noise. You can raise the height by placing blocks with adjusted heights, or try making a DIY platform, but if there is no problem with the weight and size, you can use a commercially available raising platform. It is convenient to use. The raised table also has casters, so it is easy to clean. Refrigerators are heavy, so two or more people should work together when installing a raising stand. If the work is difficult, you can also ask a professional contractor, although it will cost money.©︎https://www.photo-ac.com/
・Contact the manufacturer or repairer
If the above solutions do not fix the problem, contact the manufacturer or repairer for more professional advice.

・Purchase a new refrigerator
As a result of the inquiry, if the refrigerator is old, it may not be possible to repair it because there are no parts. Also, even if you can repair it, the repair fee may be unexpectedly high. You may be in a situation where you can buy a new product in a little while. And while it's being repaired, the refrigerator won't be there, so it will affect your life. If the repair fee is high or if you feel that the life is about to expire, it may be a good idea to consider purchasing a new one. If you buy a new one, the time without a refrigerator will definitely be shorter.©︎https://www.photo-ac.com/
■ Is it noisy because of the location of the refrigerator?
In rare cases, if the refrigerator is placed in a bad location, the side of the refrigerator that normally does not touch the floor may hit the floor and cause abnormal noise or vibration. If you haven't been able to solve the problem with the previous solutions, we recommend that you check it once.©︎https://www.photo-ac.com/
・Refrigerator is tilted
If the refrigerator is tilted when installed, the door will also be tilted, making it difficult to close or making noise when it hits the floor. If the floor on which the refrigerator is to be installed is slanted, try adjusting the height of the legs of the refrigerator on the left and right or laying down a vibration-proof mat. You can check the legs of the refrigerator by removing the front lower cover.©︎https://www.photo-ac.com/
・The refrigerator is wobbly
The height of the legs of the refrigerator can be adjusted, so if the height is different during installation, it will wobble. It is transmitted and feels like a loud sound. You can adjust the height by turning the legs of the refrigerator.©︎https://www.photo-ac.com/
・Move if it has casters
If the floor is damaged, heavily dented, or slanted badly, etc., if the above two things do not work, you will need to move the refrigerator itself. I have. Because it is heavy, it is difficult to move it alone, but if it has casters, it can be easily moved, so we recommend that you check it once. You can check if the casters are attached by pulling the front cover under the refrigerator to remove it. If you can confirm that there are casters, they will loosen when you rotate them, so turn them. You can easily move it by pulling it out slowly.©︎https://www.photo-ac.com/

When the refrigerator is noisy and you can't sleep because of the noise, you want to find the cause and deal with it as soon as possible. In such a case, please refer to the workaround introduced this time. I would like to deal with it without sending it to repair as much as possible, but if I deal with it incorrectly, it may cause further damage, so if you can't figure out the cause, one way is to ask a professional. In addition, it is no exaggeration to say that the refrigerator is the most closely related part of our lives, so it is a good idea to deal with even the slightest abnormality without overlooking it. If you feel that there is even a slight noise, you should check each part of the refrigerator frequently and take care of it so that it can be used for a long time.©︎https://www.photo-ac.com/
