What s going on with a popping sound when the refrigerator is running

The sound of ice crackling. That is, the moisture in the refrigerator seeps into the foam layer, and when it cools down or heats up, it freezes or melts, due to the change in volume, it produces stress, and it cracks after a certain extent, and the sound is generated.

There are mainly the following reasons why refrigerators emit noise:

1. The placement level is not adjusted: the simple method is that the left and right sides are not obviously tilted, and the front and rear doors will not be opened and closed naturally.

2. All four feet do not land: pay attention to the adjustment level at the same time.

3. The compressor itself is noisy: if there is an obvious knocking sound, it is a fault.

4. Other parts are fixed and loose: what can be seen is the pipeline in the box.

5. The slightest sound of water flow and gas: normal.

6. Resonance of bottles and boxes in the refrigerator: move the position of the items.

7. Environmental resonance: move the refrigerator a little bit, or put some appropriate heavy objects on the top.

8. The sound of ice cracking after the ice melts and pops open between the refrigeration pipelines.

It is normal for some refrigerators to pop or knock when the compressor is first in operation, or when the compressor is shut down for a short time. It is usually caused by deformation of certain parts caused by changes in the temperature of the condenser. Built-in condensers (flat-back) are sometimes seen, and this sound is also generated in the evaporator.

Don't panic. Now, with the continuous progress of scientific and technological means, the phenomenon of material renewal occurs less often.

No problem, the temperature is low in winter, the refrigerator is too lazy to start, causing a large temperature difference and a sound from a sharp drop in temperature.

It is recommended to play until winter, and then turn the thermostat a little bigger, but do not adjust it to the end...

Normally, the popping sound caused by the freezing of the box during refrigeration. You can use it with confidence. There is no danger.

1. Noise caused by compressor:When the top of the compressor is pressed by hand, the noise is still unreduced, usually the noise caused by the gap between the piston and the cylinder inside the compressor is too large, and the compressor should be replaced. In addition, when the refrigerator is not opened, if the sound of boiling or interval sizzling can still be heard about 3 meters away from the refrigerator, it means that the refrigeration pipeline is aging or malfunctioning.

A professional should be asked to replace the compressor.

2. Noise caused by uneven placement of the refrigerator:Place a piece of hard rubber at the foot of the refrigerator, such as an old cloth sole, not too thick, and properly raise the four corners of the refrigerator to increase the air convection space at the bottom of the box. In this way, the compressor noise and other lower noises can come out of the bottom of the box, which reduces the noise coming out of the sides and upper parts of the refrigerator.

Precautions for refrigerator use.

1. When the refrigerator is in use, it is necessary to keep it powered on all the time, if it is not powered for a long time, the refrigerator is easy to be damaged.

2. When the refrigerator door is opened, it should be closed immediately to ensure that the air conditioner runs away and causes electricity consumption.

3. The sealing ring of the refrigerator should be observed, and if it cannot be completely adsorbed, or if it is not sealed and leaking, it should be replaced.

4. When storing fish or fishy food in the refrigerator, cover it with plastic wrap to prevent the fishy smell from affecting other foods.

This is the reason why the compressor is broken, the anti-vibration hook inside the compressor is off, or it is broken, and the compressor can be used, but the sound will be very loud when it starts and stops! It will also be louder than usual during operation It is recommended to replace the compressor!

You're probably exaggerating a little bit, but it's probably caused by uneven floors and compressor work.

The problems caused are: 1. There are foreign objects next to the compressor for a long time, resulting in short circuits. 2。

There is a problem with the compressor. 3. The location of the refrigerator is uneven [such may be very small] It is strongly recommended: it is very dangerous to use this way, please report for repair as soon as possible, and let professional after-sales personnel come to maintain it!

When this sound occurs, it may be that the lubricating oil of the refrigerator compressor is insufficient, if there is not enough lubricating oil inside the compressor, this sound will be produced when the shutdown is carried out, when this situation occurs, you can ask a professional refrigerator maintenance master to add some lubricating oil to the refrigerator compressor, which can solve the noise problem.

In addition to this, the following conditions can also cause the refrigerator to make occasional noises:

1. If the refrigerator is not completely horizontal, then the internal rotor may hit the inner wall of the compressor when the refrigerator is running, and then produce a sound, in this case, it is only necessary to adjust the refrigerator to the horizontal state as soon as possible.

2. If the compressor of the refrigerator is not fixed, then there will be a loud sound when the compressor is stopped and started, and when this is the case, the screws of the compressor need to be fixed again.

3. When the refrigerant of the refrigerator is only very small, the refrigerant will occasionally make a banging sound when it refluxes in the pipeline, and there will be no problem after adding a sufficient amount of refrigerant to the refrigerator at this time.

4. The refrigerator generally runs intermittently, when the temperature in the refrigerator is higher than the set temperature, the thermostat spring blade of the refrigerator will spring back to connect the circuit, and this process may also produce loud sound, which is a normal phenomenon and generally does not need to be worried.

Summary. What is the problem with the sound of ice cracking in the refrigerator?

The main reason for the ice cracking sound of the refrigerator is that water enters the thermal insulation foam of the refrigerator, at the junction of freezing temperature and room temperature, when refrigerating, the water becomes ice, and when it is shut down, the ice turns into water, due to the characteristics of water, it will expand after freezing, and the sound of stress changes.

1. Generally, it is caused by the refrigerator not being placed horizontally. 2 is that the four corners do not have good contact with the ground. There are empty corners. 3. The compressor fixing screw is not tightened. 4. The shockproof rubber block on the exposed pipe of the refrigerator has fallen off.

Check whether the devolution is flat.

No problem with this.

**The situation is difficult to appear, the temperature is high in summer, the compressor starts frequently, the sound is made when the compressor is running, it generally doesn't matter, but you need to pay attention to whether there is too much ice in the refrigerator, and whether the sealing strip is closed and complete, so it will not be **. If you're scared, find someone to fix it.

The reason may be that the refrigerator is not placed on a flat ground, which causes the rotor inside the refrigerator to collide with the inner wall of the compressor when it is stopped, so there is a noise, and the positioning attitude of the refrigerator can be adjusted to the level; The reason may be the lack of lubricating oil inside the compressor of the refrigerator, and the compressor makes a noise during the shutdown of the refrigerator, so you can contact the after-sales maintenance personnel to supplement the lubricating oil for the compressor of the refrigerator to avoid the serious failure of the refrigerator compressor due to the lack of lubricating oil.

In addition, there may be a situation similar to the fact that the compressor of the refrigerator has not been fixed firmly, resulting in a bursting noise when the refrigerator starts, in this case, we need to fix the screws of the refrigerator compressor after investigation, and it is also best to lay a rubber pad to absorb the shock. In the process of using the refrigerator, if it is found that the refrigerant of the refrigerator is insufficient, then when the refrigerator is stopped, the reflux of the refrigerator refrigeration system can hear the sound, and then only need to add refrigerants such as freon to the refrigerator. At the same time, during the operation of the refrigerator, intermittent rolling and tease occasionally occurs, especially when the ambient temperature outside is higher than the refrigeration temperature set by the refrigerator, the spring of the temperature controller of the refrigerator will bounce back, so as to turn on the circuit, at this time we can also hear the noise, so if you encounter this situation, you generally do not need to worry.
