Reasons and solutions for refrigerator not refrigerating:1Check if there is not enough refrigerant in the refrigerator, because refrigerator refrigeration relies on the support of refrigerant.

Therefore, when the refrigerant in the refrigerator is insufficient and the refrigerator can operate normally in time, there will be no refrigeration in the refrigerator, so when the refrigerator is not cold, it is best to ask a professional master to check whether it is because of the problem of refrigerant. If the refrigerant is insufficient, add the right amount of refrigerant in time. 2.

Check whether the refrigerator is not working properly due to too much food in the refrigerator. However, due to food clogging, cold air does not diffuse well in various parts of the refrigerator. In particular, the air outlet of the refrigerator is the main place where cold air is transmitted.

Therefore, if it is really caused by too much food in the refrigerator after the inspection, it is best to reduce the food in the refrigerator, so as to ensure the smooth flow of the air outlet and the gap between the food where cold air can circulate. 3.Check if there is a problem with the compressor of your refrigerator, as the compressor of your refrigerator is one of the most important parts of your refrigerator.

So, when the compressor of the refrigerator fails, the refrigerator will be poorly cooled and the inside of the refrigerator will not be cool. This requires professional home appliance maintenance personnel to check and repair in a timely manner. For example, if the fuse of the compressor is blown out, it is enough to replace the fuse with a new one in time.

Reasons why the refrigerator refrigerator is not refrigerated 1. The high-pressure output buffer pipe in the compressor is broken, or the screws fixing the tube are loose, resulting in the high-pressure pipe not exhausting and the low-pressure pipe not suctioning, so although the compressor is running, it is not refrigerated. 2. The refrigerator thermostat is installed in the refrigerator, and the temperature of the refrigerator does not reach the temperature required by the thermostat, so it does not stop. If the compressor does not work around the clock, the freezer compartment may cause the refrigerant to reach the maximum refrigeration temperature.

Most of this phenomenon occurs in air-cooled refrigerators. The reason is that the evaporator flower froster in the cold room is broken, which produces an ice blockage. It cannot be ruled out that the air cooling fan is broken, and there are too many items in the refrigerator to block the air outlet, causing poor cooling effect.

3. The refrigeration system leaks, the refrigerant runs out, and although the compressor is running, there is no refrigerant evaporation and heat absorption in the system, so the temperature in the refrigerator does not drop. 4. The temperature of the refrigerator is automatically adjusted with the temperature adjustment of the freezer, and the temperature of the freezer can be lowered. Generally, the temperature of the refrigerator room is 4-10 degrees Celsius.

Note that the higher the number of the temperature controller, the lower the temperature, the higher the number in summer and the smaller number in winter. In addition, the refrigerator door is often opened, and there are many items in the refrigerator, resulting in the refrigerator not being refrigerated or the refrigeration effect is not ideal. 5. If your refrigerator is intercooled, check whether the fan is working.

Open the door of the freezer compartment and press and hold the button at the edge of the box mouth with your hand (this button controls the indoor lighting and stops the fan from working when the door is opened) to see if the fan is working, as the fan does not work will cause the refrigerator to not refrigerate. In addition, too much food can also affect the refrigeration effect. 6. The reason why the refrigerator refrigerator is not refrigerated may also be that there is a problem with the refrigerator compressor.

The compressor can start, remove the return pipe and block the outlet with your fingers, check how much the pressure is, if it is too low, then there is a problem with the compressor The compressor can not be started, check whether the refrigerator power supply is plugged in. 7. Open the door of the refrigerator and see if the light in the box is on to determine whether the power of the refrigerator is turned on. If the light is not on, use a pen or multimeter to check whether there is electricity in the power socket and whether the power plug of the refrigerator is well plugged in.

8. Use a multimeter to check whether the power supply voltage is lower than 187 volts, because the normal use voltage of the refrigerator is 187V — 242V according to the national standard (unless otherwise stated by the manufacturer), and the compressor of the refrigerator below 187 volts cannot be effectively started normally. 9. When the ambient temperature is lower than the normal starting temperature of the temperature controller, check whether the low temperature switch of the refrigerator is turned on. Only when the low temperature switch is turned on can the temperature controller be forcibly turned on.

10. If the compressor can work, judge whether the refrigeration system has refrigerant (commonly known as potion). Let the refrigerator run for a few minutes before unplugging and listen carefully for the sound of liquid running inside the copper tube. If not, it means that the refrigerant in the system has leaked, or the compressor has lost its capacity.

The reasons may be:

1. The refrigerator freezer leaks cold and has poor sealing.

2. The refrigerant leaks slowly, and the refrigerant is not very sufficient, resulting in poor refrigeration capacity, and the refrigerator needs to work continuously, but it can also be refrigerated, and the refrigeration will be worse after a period of delay.

3. The air-cooled refrigerator may have too much ice in the freezer compartment and blocked the air inlet of the refrigerator, so it is recommended to try defrosting.

Types of refrigerators and corresponding refrigerator refrigeration principles:

1. Compression refrigerator: This kind of refrigerator provides mechanical energy by the electric motor and works on the refrigeration system through the compressor. The refrigeration system is made by using the principle of low boiling point refrigerant to absorb heat during evaporation.

2. Absorption refrigerator: This kind of refrigerator can use hot stove sources (such as gas, kerosene, electricity, etc.) as power. The ammonia-water-hydrogen mixed solution is used to achieve the purpose of refrigeration in the continuous absorption-diffusion process.

3. Semiconductor refrigerator: It is a refrigerator that uses the principle of direct current to produce the Peltier effect on the junction of the PN-type semiconductor.

4. Chemical refrigerator: It is a refrigerator that uses certain chemicals to absorb heat strongly when dissolved in water to obtain the refrigeration effect.

5. Electromagnetic vibrating refrigerator: It is a refrigerator that uses an electric leather magnetic vibrating machine as the main power to drive the compressor. Its principle and structure are basically the same as those of compression refrigerators.

If the upper level of the refrigerator is not cooling, there may be several reasons:

Incorrect refrigerator temperature setting: Check that the refrigerator's temperature setting is correct. If the temperature is set too high, it may cause the upper level to not refrigerate.

Poor refrigerator door sealing: Check the refrigerator door sealing. If the seal is poor, it will cause cold air to leak out, resulting in the upper layer not being cooled.

Blocked refrigerator drain holes: If the refrigerator drain holes are blocked, condensate will not be able to drain out, which will affect the cooling effect of the refrigerator.

Dust accumulation in the refrigerator radiator: If the refrigerator radiator is dusty, it will affect the heat dissipation effect, which will lead to chaos and cause the upper layer to not refrigerate.

Refrigerator refrigeration system failure: If the above situations are eliminated, then it is likely that the refrigerator refrigeration system is faulty. This condition may require repairs by a professional technician.

It is recommended that you check the above aspects first, if the problem still exists, it is best to contact professional and technical personnel for maintenance.

There are many reasons for not refrigerating, such as faulty wiring, poor door sealing, blocked capillary tube of the refrigerator, faulty compressor, no refrigerant in the refrigerator, broken defroster, faulty fan, and wrong thermostat adjustment. When there is no refrigeration, the first thing to do is to check whether there is a problem with the power supply and wiring. You can carefully check that the power connection of the refrigerator is normal, and then check that the light seepage cavity in the refrigerator is working properly.

If it is judged that it is indeed a problem with the line, it is recommended to find a professional to repair it.

Reasons why the upper level of the refrigerator may crack if it is not refrigerated includes:

1.There is a blockage or blockage on the inside of the refrigerator, resulting in poor air circulation.

2.The fan or air duct on the upper level is faulty, affecting air circulation.

3.The temperature regulator on the upper level is damaged or malfunctioning, and the temperature cannot be controlled.

4.Refrigerant leakage or refrigeration system failure, resulting in the upper layer not being able to cool normally.

It is recommended that you contact a professional maintenance personnel to inspect the refrigerator and repair the liquid attack to bury the stove.

1. It may be that there is a problem with the buffer tube that causes the top layer of the refrigerator to not refrigerate. 2. The low ambient temperature causes the top layer of the refrigerator to not refrigerate. 3. It may be that the refrigerator refrigerant leaks and the refrigerant is insufficient, resulting in the top layer of the refrigerator not being refrigerated.

4. It may be that the fan of the refrigerator is not operating normally, and the top layer of the balanced refrigerator is not refrigerated.

Suggested workaround:

1. The high-pressure output buffer pipe in the compressor is broken, or the screw fixing the tube is loose, which will cause the high-pressure pipe to not exhaust and the low-pressure pipe to not suction, which will cause the compressor to run but not refrigerated.

2. When the ambient temperature is lower than the normal starting temperature of the temperature controller, check whether the low temperature switch of the refrigerator is opened. The refrigerator thermostat is installed in the refrigerator, and the temperature of the refrigerator does not reach the temperature required by the thermostat.

3. If the indoor temperature is low at this time, the temperature of the refrigerator should be adjusted to 7, and the temperature compensation switch should be turned on, and then the professional maintenance personnel should add the refrigerator refrigerant.

4. Open the refrigerator door of the refrigerator, press and hold the small button at the edge of the box mouth with your hand (this button is to control the indoor lighting of the refrigerator and stop the fan when the door is opened), check whether the fan is working at this time, and the fan will not work will also cause the refrigerator to not refrigerate.

1. It may be due to the leakage of the refrigerant in the refrigeration system.

All run out, although the compressor is running, but there is no refrigerant evaporation and heat absorption in the system, so it will lead to the situation that the upper layer of the refrigerator is not refrigerated. 2. It may also be the thermostat of the refrigerator.

If there is a malfunction, if the thermostat is faulty, it will also cause the refrigerator to not refrigerate. 3. If the compressor of the refrigerator fails, it will also lead to this problem. 4. Or it is due to the failure of the power supply circuit of the refrigerator, resulting in the upper layer of the refrigerator not being refrigerated.

Suggested solutions: 1. First of all, check whether the refrigerator power plug is plugged in and the power socket.

Whether there is electricity, if the plug is not plugged in properly, the plug needs to be plugged in, if the power socket is out of power, then you need to replace it with a new power socket to try. 2. In addition to the problem of electric seepage source, it is the failure of the refrigerator itself, you need to check whether the thermostat of the refrigerator is faulty, if the thermostat is faulty, then you need to replace the thermostat with a new one. 3. Also check whether it is a leak in the refrigeration system, if there is a leak in the refrigeration system, then you need to find a professional maintenance personnel to fill the leak, and you need to add sufficient refrigerant after the leak, so as to solve the problem that the refrigerator is not refrigerated.

4. If these problems are eliminated, it may be that the compressor of the refrigerator is faulty and needs to find professional maintenance personnel to repair it.

The upper floor of the refrigerator is generally set up for the refrigeration compartment. Not for refrigeration.

The most likely thing is that there is some degree of refrigerant leakage in the piping of the refrigerator refrigeration system.

When the refrigerant leaks and the amount of refrigerant is insufficient, the low-temperature and low-pressure liquid refrigerant has evaporated in the freezer pipeline below, and the refrigeration and cooling effect can be very poor or even no when it reaches the refrigerator room pipeline.

It is recommended to carefully detect the leak of the refrigerator refrigeration system, find the refrigerant leakage point, braze and repair the leakage, vacuum pump vacuuming, and refill the standard amount of new refrigerant after the negative pressure is qualified.

The main causes of this problem are as follows: it may be that the evaporator in the cold room is faulty, which can be solved by asking a professional maintenance master to repair it; It is possible that the compressor of the refrigerator is faulty, you can check whether the power supply is plugged in or check the pressure of the compressor for repair. It may be that the power supply is not plugged in properly, and the power plug can be plugged in to solve the problem; It may be that the line voltage is not enough, so you have to move or replace a refrigerator with low voltage demand.

It is possible that the evaporator in the refrigerator room is faulty, so that the ice in the refrigerator is generated, and these ice cubes block the air outlet, so that the cold air of the refrigeration system can not be discharged to the upper layer of the refrigerator, and the evaporator of the refrigerator will fail over time.

It may be that the compressor of the refrigerator is faulty, and it is necessary to remove the return pipe and block the outlet with your fingers to facilitate the inspection of the pressure.

It is possible that the power supply is not plugged in properly, check the light of the refrigerator, if it is not on, it may be that the power supply is not connected, and you need to plug it in tightly.

If the voltage is not enough, check whether the power supply voltage is lower than 187 volts, and the compressor of the refrigerator below 187 volts will not start normally. The only way to do this is to replace the refrigerator with a smaller voltage demand.

But the pants sail can be caused by the following reasons:

1.The air duct on the top of the refrigerator is blocked or damaged, resulting in poor air circulation, which affects the cooling effect.

2.The temperature sensor on the top of the refrigerator is faulty, resulting in an inability to accurately sense the temperature, which affects the cooling effect.

3.The condenser on the top of the refrigerator is contaminated or damaged, resulting in reduced cooling efficiency.

4.The compressor on the top of the refrigerator is faulty, causing it to not function properly, which affects the cooling effect.

Workaround:1Clean the air duct on the top of the refrigerator to ensure good air circulation.

2.Replace the temperature sensor on the top of the refrigerator.

3.Clean the top of the refrigerator with a condenser, or replace a damaged one.

4.Replace the compressor on the top of the refrigerator.
