Why does the refrigerator occasionally ring

The reason why the refrigerator occasionally rings: It is the sound of freezing and cracking on the condenser tube, the refrigeration program of the refrigerator is determined by the refrigerator thermostat, when the user adjusts the thermostat to 3-4 gear, the refrigerator starts to start the working program for refrigeration due to insufficient internal temperature.

Because the refrigerator will rest when the refrigeration reaches the set temperature, and wait until the temperature is higher than the set temperature before starting the refrigeration, which is what you call an occasional ring.

Why does the refrigerator occasionally ringThis is normal, this is the sound of the compressor.

In this case, you should have a certain fault in the refrigerator, and you had better have a professional repair to see what caused it? Because the refrigerator is better to notify the electronic thing, it is better to take a look.

When the refrigerator rings, the compressor starts working, so it starts.

That's the compressor running.

The temperature inside the refrigerator will slowly rise due to the refrigerated food in the refrigerator itself and the sealing of the refrigerator, when the internal temperature reaches the highest temperature point of the user's set temperature. The refrigerator starts the refrigeration program again, and when the refrigerator starts and stops, there will be a sound of the compressor working and stopping.

This cycle goes on and on, so the user will hear the refrigerator ring every once in a while, and that sound is the sound of the compressor starting or stopping.

The refrigeration program of the refrigerator is determined by the refrigerator thermostat, when the user adjusts the thermostat to 3-4 gears, the refrigerator starts to start the working program for refrigeration due to insufficient internal temperature. When the internal temperature is slowly reached by the system cooling to the temperature set by the user, it starts to stop working and is in standby mode.

What is the reason for the occasional ringing of the refrigerator Hello dear, this "bang" is the sound of thermal expansion and contraction of the plastic casing caused by temperature changes. The refrigerator is a process of compressor working and refrigerant circulation to reduce the temperature in the room, so as to ensure the freshness and nutrition of the food in the refrigerator. When the refrigerator is working, due to the change of temperature difference, the refrigeration evaporator, pipes and boxes make a "spurting" or "popping" sound due to thermal expansion and cold contraction.

This is a normal physical phenomenon. Please don't worry, it will not affect the use of the refrigerator. In daily life, some thin pipes or shells will also make similar sounds due to thermal expansion and contraction when they are slowly heated or exposed to the sun.

In addition, thermal expansion and contraction is the expansion of materials after being heated, and shrinking when they are cold. When the temperature of the object increases, the kinetic energy of the molecule increases, and the average free path of the molecule increases, so it is manifested as thermal expansion; In the same way, when the temperature of the object decreases, the kinetic energy of the molecule decreases, and the average free path of the molecule decreases, so it behaves as cold contraction. But there are exceptions, such as water, which is not to say that thermal expansion and contraction are not true for water, but that there are hydrogen bonds in water, and when the temperature drops, the number of hydrogen bonds in the water increases, causing the volume to increase as the temperature drops.

When the internal temperature of the refrigerator reaches the maximum temperature point set by the user. When the refrigerator starts the refrigeration process and stops again, there will be a sound of the compressor working and stopping. This cycle repeats itself, so every once in a while you will hear the refrigerator ringing, which is the sound of the compressor starting or stopping, which is a normal phenomenon.

Extended information: About the refrigerator fault detection method: 1. Look at the evaporator.

Surface frosting: If the evaporator surface frost is uneven or not complete, the refrigerant in the refrigeration system is indicated.

Insufficient, there are leakage points. If the frost layer on the surface of the evaporator is too thick, it should be defrosted or re-adjusted in time. 2. Look at the cooling rate of the freezer:

If the cooling rate is significantly lower than the original normal operation, it is due to the refrigerator door is not closed tightly, the refrigeration system lacks refrigerant, and the condenser.

It is caused by too much ash on the surface or too thick a frost layer on the surface of the evaporator. These will make the compressor work for a long time, and the temperature will drop very slowly. 3. Look at the outer surface of the refrigeration system (especially the joints and the surface of the evaporator):

If there are oil stains on the outer surface of the refrigeration system, it means that there is leakage, which will cause a decrease in refrigeration capacity, uneven or incomplete frost on the surface of the evaporator, and completely lose the refrigeration capacity of the refrigeration system. 4. Look at the suction line on the compressor: if there is frost or condensation on the gas pipeline, it may be that the refrigerant is overcharged, or the frost layer of the evaporator is too thick, resulting in the refrigerant liquid can not be gasified well in the evaporator and reach the suction pipeline for further heat absorption and gasification of frost and condensation.

In severe cases, frost and condensation may appear on the compressor.

The fridge sometimes suddenly pops What's going on:

1. This situation may be caused by not being placed flat, because if the refrigerator is in this uneven state, the compressor inside it will collide with the cylinder, which will make a gurgling sound, and only need to reposition it at the four corners.

2. It may be caused by the unstable voltage of the refrigerator, because if the voltage is not stable, there will be abnormal sound when the internal compressor is running. In this case, you need to ask a professional electrician to check the voltage.

3. It may also be caused by severe frost in the refrigerator room, if this situation is not dealt with in time, the drainage pipe at the bottom of the back wall will be blocked, resulting in an abnormal sound.

Refrigerator use tips:

1. Pay attention to the temperature.

The refrigerator should not be opened for too long, otherwise it will increase the temperature inside. Also, it is not advisable to store too much food in the refrigerator as this will obstruct the circulation of cold air. It is worth mentioning that it is not the right choice to put leftovers of food directly in the refrigerator with residual warmth, and let it cool before putting it in.

2. The inside of the refrigerator should be managed by partition.

In the refrigerator, vegetables and fruits can be placed at the bottom, eggs and dairy products can be placed on the top, and leftovers and leftovers can be placed in the middle layer. Dishes with soup should be placed in a bowl with a deep bottom to prevent the soup from leaking; Leafy greens cannot be left overnight; Once dairy products or sauces are opened, the bottle must be tightened when storing.

The refrigerator keeps ringing, first check whether the refrigerator is frozen, if not, the refrigerant leakage of the refrigeration system, no matter how hard the compressor works, it cannot reach the set temperature of the refrigerator. If the refrigerator has moved very thick ice and the refrigerator is still cooling, it means that the refrigerator thermostat is damaged, and you can replace one.

The refrigerator is the most indispensable household appliance in family life, but after a long time, some small problems will come out, such as the refrigerator keeps ringing, so what is the reason for this phenomenon? Let's take a look.

1. The refrigerator thermostat is faulty. If the refrigerator thermostat leaks fluorine or the temperature sensor cannot feel the temperature, it means that the control circuit board of the refrigerator is faulty, resulting in the refrigerator being in an uncontrolled state and working all the time.

2. Too much food is stored in the refrigerator. If there are too many things inside the refrigerator (especially around the thermostat), it can be a burden relative to the refrigerator because it has to work continuously to keep the refrigerator cool.

3. The temperature of the external environment is too high. This is because the outside temperature is too high, resulting in slow heat dissipation in the refrigerator, we know that the slower the refrigerator dissipates heat, the more it affects refrigeration, and the less easy it is to refrigerate, the refrigerator is likely to work all the time. In the same way, if the refrigerator door is not closed tightly, it may also cause the refrigerator to not stop.

Extended Information: Refrigerator Common Troubleshooting:

Fault script opening phenomenon: The refrigerator alarm keeps ringing.

1. Electrical failure.

Generally speaking, the refrigerator can be frozen to -21 degrees, and some can reach -30 degrees. If the temperature rises to -10 degrees alarm, there is a considerable amount of time to process the frozen food and avoid the loss caused by rotting.

2. The temperature controller is faulty.

When in hot weather, the thermostat of the refrigerator will also fail, resulting in the refrigerator not stopping, the main reason is that the thermostat thermostat head can not feel the temperature change inside the refrigerator and the fault of the control circuit board.

3. The ambient temperature is too high.

If the ambient temperature of the refrigerator exceeds 32 degrees, the refrigerator is prone to non-stop, which is caused by the low power of the refrigerator compressor or too little refrigeration capacity.

4. The refrigerator door is too tight.

After the refrigerator has been used for a period of time, it is not as easy to open the door as when it was first bought, and it takes a lot of force, and sometimes even the rubber sealing strip of the refrigerator door will be pulled out of the fixing slot. This phenomenon can easily occur during the summer months.

It mainly depends on the refrigeration performance of the refrigerator, and the phenomenon of icing indicates that the temperature of the refrigerator is too low or faulty. Often, don't worry.
