How to repair the refrigerator if it is not refrigerated, how to repair the refrigerator if it is no

What to do if the refrigerator does not refrigerate: first, check the power supply, open the door, check whether the light is on, or test with an electric pen to see if the socket is energized. Second, check the compressor, if the power connection is normal, listen to whether the compressor is working.

Third, whether the refrigerant is leaking. Fourth, the issue of temperature setting. Finally, if you really can't find the problem, ask a professional master to check it.

How to repair the refrigerator without refrigeration:

1. Refrigerant runs out or leaks.

If the compressor can run normally, the next step is to check whether the refrigerant in the refrigeration system is used up: you can let the refrigerator run for 3-5 minutes, cut off the power supply, and listen to whether there is a sound of water flowing. If there is no sound.

This means that the refrigerant in the refrigeration system has been used up or is leaking. It could also be that the compressor is incapacitated.

Solution: If there is a system leakage, by finding the leakage part of the system, after welding repair, pressure test, and evacuation are qualified, add refrigerant to a certain amount, usually according to the evaporator is full of frost or the refrigerator reaches the rated temperature.

Second, the compressor screw is loose.

If the power connection is normal, you can monitor whether the compressor is working properly. The compressor emits a small motor vibration sound during normal operation. When the high-pressure output buffer pipe in the compressor is broken, or the screw fixing the tube is loose, the high-pressure pipe is not exhausted, and the low-pressure pipe is not suctioned, so the compressor is running, but it is not refrigerated.

Solution: Open the casing, replace it with a new one, or tighten the screws.

3. The capillary of the refrigerator is now blocked.

The blockage of the refrigerator capillary will also cause the refrigerator to not refrigerate. When the capillary tube in the refrigerator is blocked, the refrigerant cannot enter the evaporator to absorb heat and exert its effect, resulting in the temperature of the refrigerator remaining high.

Depending on the type of refrigerator, the refrigeration situation will also vary. If the refrigerator belongs to the inter-cooling type and there is no ice failure, you can check whether the fan of the refrigerator is working normally: open the refrigerator door of the refrigerator, press and hold the button at the edge of the box mouth with your hand to check whether the fan is working, and the fan will not work will also cause the refrigerator to not refrigerate.

Solution: The capillary or dryer is clogged, and the outlet is hot, so remove it to remove it! In addition, household refrigerators generally have two types: direct cooling type and intercooling resistant auspicious group type, direct cooling type refers to the evaporator (cooling pipe) directly with the refrigeration, refrigeration room for heat exchange to achieve the purpose of cooling; Intercooling means that the evaporator (cooling pipe) is separated from the freezing and refrigeration room, and the cold air is blown into the freezing and refrigeration room by a fan to achieve the purpose of cooling.

It may be because the compressor fuse is blown out because the temperature is too high, and the problem is solved by replacing the fuse in the refrigerator; It may also be caused by the fact that the refrigerator stores more food, which can be solved by reducing the amount of food in the refrigerator; It may also be that the refrigerator defroster is damaged, which can be solved by replacing it with a new defroster; It could also be that the fan in the refrigerator is malfunctioning. If the compressor of the refrigerator works for a long time, resulting in an increase in the internal temperature of the compressor, if the heat is not dissipated in time, the fuse will break, resulting in the refrigerator not refrigerating, and the fuse in the refrigerator needs to be replaced again, and the compressor is cooled down. If the refrigerator stores a lot of food, some food is leaning on the inner wall of the refrigerator, which causes the refrigerator freeze and does not refrigerate, take out the food in the refrigerator, melt the ice in the refrigerator, and pay attention to the food not to be close to the inner wall of the refrigerator when placing it in the later stage.

If the defroster in the refrigerator is damaged, and the ice in the refrigerator is not cleaned up in time, the ice in the refrigerator will block the ice clearing box, resulting in its refrigeration, so it needs to be replaced with a new defroster, and the ice in the refrigerator should also be cleaned up. If the fan in the refrigerator is faulty, resulting in the refrigerator not being able to dissipate heat in time, or even blocking the air outlet because there is more food in the refrigerator, you need to repair the exhaust fan first, and dredge the air outlet.

First of all, it is necessary to find out the main reason why the refrigerator is not refrigerating, check whether the compressor of the refrigerator is normal, you can unplug the refrigerator, and then listen to the sound of liquid activity in the copper pipe. The compressor failure must be repaired in time, otherwise it will affect the normal use of the refrigerator. It is best to ask a local professional master to come to your door.

The manufacturer who buys the refrigerator will give a three-year warranty, which means that if the refrigerator fails within three years, you can contact the manufacturer and ask the manufacturer to arrange staff for on-site maintenance. Refrigerator repairs during the warranty period are free of charge.

Reasons why the refrigerator does not refrigerate

1. Line problems: When there is no refrigeration, the first thing is to check whether there is a problem with the power supply and line. You can carefully check whether the power connection of the refrigerator is normal, and then check whether the lights in the refrigerator are working normally, and if necessary, you can use an electric pen to detect, after all, the line is the most prone to failure, resulting in no refrigeration.

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

2. The door seal is not tight: when there is no fault in the line of the refrigerator, then the next thing to see is whether the refrigerator door is tight. Some families may put too much food in the refrigerator, and frequent opening of the door or poor sealing of the door will lead to the problem of not cooling.

3. Blockage of the capillary tube of the refrigerator: In fact, the blockage of the capillary tube in the refrigerator will also cause the refrigerator to not refrigerate. Because once the capillary is blocked, the refrigerant will not be able to enter the evaporator, and the heat cannot be effectively absorbed, so that the temperature of the refrigerator cannot be lowered.

If the capillary or dryer is clogged, the solution is simple, just remove it and remove it.

4. There is a problem with the refrigerator compressor: if there is a problem with the compressor of the refrigerator, it will also cause the refrigerator to not refrigerate, how to judge that the compressor is faulty? Some methods can be used, for example, if the compressor can be started, then you can remove the rotten skin of the return pipe, and then block the outlet by hand, if it is too low, then there is a problem with the compressor, which needs to be replaced or repaired in time.

5. Refrigerator without refrigerant: refrigerant, in fact, is what we call refrigerant in daily life, if the compressor can work normally, there is no problem in all aspects, then it depends on whether the refrigerator is free of refrigerant. You can unplug the refrigerator after running for a few minutes, listen to the sound of liquid flowing in the copper tube, if not, there is no refrigerant, you need to re-add it.

Refrigerator not refrigerating repair:

1. Check the power supply.

First, check that the power plug is plugged in securely and check that the refrigerator door light is on to determine if the refrigerator is plugged in. If the power plug is fine, test the power outlet with an electric pen. Hebi.

2. Check the compressor.

At normal ambient temperature, when the refrigerator is started, if the compressor makes a "hum" sound, and the compressor stops working for about half a minute, it is because the power supply voltage is too low and the compressor cannot start.

If the compressor makes a "grace" sound followed by a "pop" sound, this situation is caused by the supply voltage being too high or the compressor working continuously for too long. When the mains voltage returns to normal or the compressor housing temperature decreases, the refrigerator will work normally.

3. Check the defrosting system.

Air-cooled refrigerators usually have only one steaming trace, when the evaporator frost can not melt away, the air duct is blocked, and the cooling capacity cannot go out, resulting in the refrigerator not refrigerating. At this point, the defrosting system needs to be checked, it may be that the defrost timer is faulty, or the heating element has burned out.

If the refrigerator is not refrigerated,First of all, check whether the power plug and power cord are well connected, check whether the power is off or the fuse is burned out, and solve the power supply problem.

The thermostat is a key component in regulating the temperature of the refrigerator, and if the thermostat fails, it can cause the refrigerator to not refrigerate. The thermostat needs to be replaced. The compressor is the core component of the refrigerator, and if the compressor fails, it may lead to a decrease in the refrigeration efficiency.

The compressor needs to be replaced. Refrigerant leaks may cause the refrigerator to not refrigerate. The leak needs to be found for repair or replacement of cold media.

The radiator is the heat dissipation part of the refrigerator, and if the radiator fails, it may cause the refrigerator to not refrigerate. The radiator needs to be cleaned or replaced. Such as fan failure, leakage, etc., may also cause the refrigerator to not refrigerate.

Before repairing, it is necessary to determine the cause of the failure and then find the corresponding repair method. If you are not sure how to repair it, it is recommended to consult a professional maintenance personnel or after-sales service to avoid greater losses.

Precautions for choosing a refrigerator

1. Volume size: When purchasing a refrigerator, it is necessary to choose the appropriate volume size according to the family population and food storage capacity.

2. Brand and quality: Brand and quality are important considerations when choosing a refrigerator, and it is recommended to choose well-known brands and guaranteed products.

3. Energy efficiency: The higher the energy efficiency of the refrigerator, the lower the energy consumption, it is recommended to choose products with an energy label of A+ and above.

4. Refrigeration technology: refrigeration technology is one of the key factors that determine the refrigeration effect and energy consumption of the ice nucleus sensitive box, and the common refrigeration technologies include direct cooling, air cooling and dual circulation.

5. Storage function: The storage function of the refrigerator includes the size of the freezer and refrigerator room, the design of the compartment and the number of storage compartments, etc., which need to be selected according to your own needs.

The repair method of refrigerator not refrigeration is: clean the exhaust port of the refrigerator, check the compressor, check the refrigerator door seal, clean the refrigerator cooler, and check the refrigerator maintenance cycle.

1. Clean the exhaust port of the refrigerator: first turn off the power of the refrigerator, and then use a vacuum cleaner or brush to clean the exhaust port and radiator on the back and bottom. Dust and dirt can block air circulation, resulting in inadequate refrigeration.

2. Check the compressor: If the refrigerator does not refrigerate, it may be due to a problem with the compressor. Check the compressor for odors or noise, and if so, it may need to be replaced.

3. Check the refrigerator door seal: If the refrigerator door seal is not tight, air will leak out from the side of the door, resulting in insufficient refrigeration. Check whether the seal is dry and broken, and if so, the seal needs to be replaced.

4. Clean the cooler of the refrigerator: The cooler is an important part of the refrigeration system, if the cooler accumulates dust or dirt, it will cause the refrigerator to not refrigerate. Cleaning the cooler can enhance the cooling effect.

5. Check the refrigerator maintenance cycle: The maintenance cycle of the refrigerator is very important, if it is not cleaned or maintained for a long time, the refrigeration effect will decline. Regular cleaning and maintenance can prolong the life of the refrigerator and ensure the refrigeration effect.

Causes and elimination methods for compressors not working due to low indoor temperature in winter and refrigeration:

Now the ambient temperature in the season is still very low, you can pour a cup of hot water into the refrigerator, after a while if the compressor starts to work without high tremor, it means that the indoor temperature of the refrigerator is too low, or the winter temperature compensation switch in the refrigerator is not opened, or the automatic compensation circuit performance is abnormal, or the compensation electric heater is damaged.

Temporary emergency can be adjusted to the highest gear many times a day in the morning, noon and evening, so that the compressor can be forced to start the work and then a little more.

You can also buy a refrigerator companion online, also called the refrigerator bosom friend, adjust the boot time to the shortest, about 5 minutes, and then adjust the shutdown time to the longest, about two hours, plug the power plug of the refrigerator into the power socket on the refrigerator bosom friend, and then plug the refrigerator bosom friend into the power socket on the wall, and adjust the gear in the refrigerator to the highest gear.

If you pour a cup of hot water and put it in the refrigerator and the compressor does not start, it is estimated that the starter on the left side of the compressor is damaged.

If the refrigerator light is not on, it means that the refrigerator power supply is not on, and you should check whether the refrigerator plug is not plugged in properly or the socket is not powered. Otherwise, it is estimated that the compressor starter is damaged.

If the compressor does not work without stopping but does not refrigerate, it should be due to damage and leakage at a certain position in the system pipeline, resulting in the loss of refrigerant liquid.
