Why does the refrigerator make a sound Why does the refrigerator make a sound all the time

This is a "running water" sound that is made when working in the system.

Refrigerators rely on refrigerants to refrigerate, and any refrigerator will emit the sound of refrigerant flow or eruption in the system when it is running, but due to the different structures and principles of refrigerators, the sound volume generated will also have certain differences. The refrigerant enters the evaporator after the capillary throttling and depressurization, because the capillary diameter is small, the refrigerant flows very fast in the capillary, and when it enters the evaporator, due to the larger diameter of the evaporator, the refrigeration will form an eruption sound at the capillary outlet, which is the normal sound of the refrigerant flow, and has no effect on the refrigerator.

No, that's normal, and most of them mean they're working. However, if you make some strange noises, you should be careful.

Why does the fridge keep buzzing.

The compressor sounds, and the older the machine, the more pronounced the sound becomes.

Tips for distinguishing the sound of the refrigerator from normal and faulty, simple and practical, do not look at it is a loss!

It is normal for the refrigerator to have a sound, if it is a hissing or gurgling running water, it may be the sound of refrigerant circulating in the refrigeration ducts of the refrigerator. If there is a rattle when starting or stopping, it is actually the sound of a hammer relay, thermal protector or defrost timer opening or closing the contacts.

It is normal for the fridge to have a sound

It is normal for the refrigerator to have a sound, and if the refrigerator makes a "hissing" sound or "gurgling" running water during use, it is a normal phenomenon, because the normal sound of the refrigerant circulating in the refrigeration pipe of the refrigerator will not affect the refrigeration effect.

If you hear a "popping" sound when the refrigerator is started or stopped, this is also normal. This is due to the sound of the contacts of hammer relays, thermal protectors or defrost timers opening or closing, and sometimes accompanied by a vibrating sound.

There is also a kind of inter-cooling refrigerator on the market, this kind of refrigerator is also called frost-free refrigerator, it sometimes makes a slight ticking sound during operation, this phenomenon is because of the sound made when the defrosting timing relay rotates, and some refrigerators will also make a slight blowing sound, which is actually the sound of cold air blowing when the evaporator small fan is running.

1. After the refrigerator is shut down, the refrigerant in the refrigeration system is restored from the gaseous state to the liquid state, and flows down the pipeline, and the sound of running water can be heard, which is generally a normal phenomenon.

2. The main reason for the phenomenon caused by the low humming electromagnetic sound emitted by the refrigerator:

1. The grid voltage is too low, and the compressor is difficult to start;

2. The connection points between fuses, sockets, plugs and other components and wires are loose, resulting in on-and-off breaks;

3. Capacitor capacitance is insufficient or deteriorates and fails. Elimination method of humming electromagnetic sound; Measure the power supply voltage, when it is less than 20% of the rated voltage, an automatic voltage regulator should be installed; Check the connection and contact status of fuses, plugs and sockets, and overhaul or replace them if they do not meet the requirements; Replace the capacitor.

3. The reason for the failure caused by the sound of the refrigerator is that the refrigerator stops running in winter and starts to use in spring. Starting the refrigerator without preheating caused the liquid to knock on the cylinder and make a clanging sound. For refrigerators that have been out of service for a long time, they should be started for 20 seconds before use, and then shut down, and repeated about 5 times before they can be put into normal operation.

4. The reason for the failure caused by the compressor vibration sound emitted by the refrigerator is that the back or side of the refrigerator is close to the wall, and the vibration sound of the compressor is transmitted through the wall. The installation position of the mobile refrigerator should be above the wall.

5. The reason for the squeaking sound of the refrigerator is that the condenser tube, the box and the low-pressure pipe of the refrigerator squeak when they collide during operation. After stopping and cooling, separate the collision with bamboo pieces, and stagger the weld joint, and the separation spacing is generally about 5mm if the force is not too large, otherwise there will be a resonance sound.

It should be that the compressor is working all the time.

It depends on the refrigeration performance of the refrigerator?

If the temperature in the refrigerator does not reach the temperature set and adjusted, it should be caused by the poor refrigeration effect of the refrigerator, and it is estimated that the refrigerant is lost due to the damage and leakage at a certain position of the system pipeline.

If the temperature in the refrigerator is lower than the adjusted temperature but the compressor continues to work without stopping, it should be caused by the abnormal performance of the thermostat, and the thermostat should be overhauled or replaced.

In addition, if the temperature in the refrigerator is adjusted too low, the position of the refrigerator is not conducive to power and heat dissipation, or the refrigerator door is deformed or the door seal is not tightly sealed, etc., it will also cause the compressor to work for a long time without stopping.
