What is the reason why the refrigerator freezer does not refrigerate

Reasons why the fridge is not cooling:

1.The high-pressure output buffer pipe in the compressor is broken, or the screw holding the pipe is loose, resulting in the high-pressure pipe not venting and the low-pressure pipe not suctioning. So, while the compressor is running, it is not cooling.

2.The refrigerator thermostat is installed in the refrigerator room, and the temperature of the refrigerator compartment does not reach the temperature required by the thermostat, and it will not stop. The reason was that the frosting device of the evaporator in the cold room was broken, which caused the ice to block.

It cannot be ruled out that the air cooler is broken, and too many items in the refrigerator block the air outlet, resulting in poor refrigeration effect.

3.The refrigeration system leaks and all the refrigerant is lost. Although the compressor is running, there is no refrigerant evaporation and heat absorption in the system, so the temperature inside the refrigerator does not drop.

4.The temperature of the refrigerator compartment of a direct-cooling refrigerator is automatically adjusted as the temperature of the freezer compartment is regulated. You can lower the temperature of the freezer.

Generally, the temperature of the refrigerator is 4-10 degrees. Note that the higher the number of the thermostat, the lower the temperature, the higher the number in summer and the smaller the number in winter. In addition, the refrigerator door is often opened, and there are many items in the refrigerator, resulting in the refrigerator cannot be refrigerated or the refrigeration effect is not ideal.

1. It may be that there is no refrigerant.

Finish. 2. It may be that there are many items in the refrigerator. 3. It may be caused by the failure of the inspection fan to work normally. 4. It may be a refrigerator compressor.

There is a problem. 5. It may be that the temperature of the refrigerator does not reach the thermostat.

requirements lead to non-refrigeration. Suggested solutions: 1. If the compressor can work normally, you should judge whether the refrigeration system still has refrigerant, that is, potion.

After a few minutes of operation, the power is cut off, listen for any flowing sound in the copper pipe, if not, the refrigerant in the system is leaking, or the compressor is no longer working. 2. The temperature of the refrigerator is adjusted with the freezer, and the temperature of the freezer is lowered. The higher the number of the temperature controller, the lower the temperature, with a large number in summer and a small number in winter.

Don't open the refrigerator door too often, and don't have too many items in the refrigerator. 3. Check whether the fan is working. Press and hold the button at the mouth of the box by hand to check whether the fan is working.

4. If there is a problem with the refrigerator compressor, remove the return pipe and block the outlet with your fingers, detect how much pressure it is, if the pressure is too low, then there will be a problem with the compressor, if the compressor can not start normally, check whether the power supply of the refrigerator is plugged in. 5. If the temperature of the refrigerator does not meet the requirements of the thermostat, the temperature is not refrigerated. If the compressor does not stop for a long time, it can cause the refrigerant to limit the refrigeration temperature, resulting in an evaporator in the cold room.

Damage, ice blockage, or the air-cooled fan is broken, or it may be that there are too many items blocking the air outlet.

1.If the compressor is not stopped, the freezer may cause extreme cooling temperatures for the refrigerant. Most of these problems occur in air-cooled refrigerators.

The reason is that the frosting device of the evaporator in the cold room is damaged, causing ice blockage. It cannot be ruled out that the air cooler is broken, and many items in the refrigerator block the air outlet, resulting in a poor refrigeration effect. 2.

It may be that the compressor high-pressure output buffer pipe is broken, or the screw that holds the high-pressure buffer pipe is not tightened, or it may be that the compressor has been working for a long time and the fuse has been blown at high temperature. Suggested workaround:1.

Open the refrigerator door and see if the lighting inside the refrigerator is on, making sure the refrigerator is powered on. If the light is not on, you can use an electric pen or multimeter to see if there is electricity in the power socket and whether the power plug of the refrigerator is plugged in. Because the original power supply was not plugged in, the refrigerator could not be cooled normally.

Just plug it in. 2.If it really doesn't work, you can find a professional to deal with it.

3.Use a multimeter to test whether the power supply voltage is lower than 187V. According to the national standard, the normal operating voltage of the refrigerator is 187V-242V (unless otherwise specified by the manufacturer), and the refrigerator compressor below 187V cannot be effectively started normally.

Reasons and solutions for refrigerator refrigerator cold room not refrigerating:

1) Analysis of the reasons why the refrigerator refrigerator does not refrigerate.

1. The high-pressure output buffer pipe in the compressor is broken, or the screw fixing the tube is 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 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. 3. The capillary is blocked, and the refrigerant cannot enter the evaporator to evaporate and absorb heat, and the temperature in the refrigerator does not drop.

2) Elimination method for the reason why the refrigerator refrigerator is not refrigerated.

1. Cut the casing, replace the buffer tube, or tighten the screws.

2. Find out the leakage part of the system first, and add refrigerant to a certain amount after passing the welding repair, pressure test and evacuation, usually according to the evaporator is full of frost or the refrigerator reaches the rated temperature.

3. The capillary tube or dryer is blocked, and the outlet is hot, so remove it to remove it! In addition, there are generally two types of household refrigerators: direct cooling and intercooling, which refers to the heat exchange between the evaporator (cooling pipe) and the freezing and refrigeration rooms 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.

Your refrigerator is not refrigerated, and the reasons why the refrigerator refrigerator is not refrigerated should be judged from the following aspects:

1: Check whether the power connection is normal. Open the door and observe whether the light in the box is lit, or test it with an electric pen.

2: If the power connection is normal, listen to whether the compressor is working. The compressor will emit a slight vibration motor sound when working normally (if you feel the vibration of the compressor by hand, you should be careful not to burn, because the compressor temperature is 40-50 in winter and 80-90 in summer).

3: The household refrigeration electrical appliance industry report shows that 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.

4: If your refrigerator belongs to the intercooled type, you should 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.

First, the power cord problem.

Test the power cord with an electric pen, the refrigerator power cord is broken is also a reason for not refrigerating, in this case we need to check whether it is a problem with the power supply, the general practice is to open the door of the box and observe whether the lighting in the box is lit. Look for signs of damage to the wires, such as being bitten by a mouse.

Second, lack of refrigerant.

Most of the capillary outlets of double-door refrigerators are advanced to the freezer to start circulation, that is to say, the refrigeration starts in the freezer At the end of the refrigerator, if the refrigerant is lacking, it is first reflected in the refrigeration room from the beginning of the refrigeration, and if the refrigerant is further insufficient, the freezer evaporator can not be frosted completely. When the outlet of the air pipe is blocked, it will cause the problem of not refrigerating.

3. Frost in the evaporator.

When the evaporator frost cannot be melted off, the air duct mouth is blocked, mainly because the air-cooled refrigerator usually has only one evaporator, 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.

1. The power supply is not connected: Under normal circumstances, the power supply of the refrigerator at home is connected, but there will be some accidents that may cause the plug to not be properly connected and the power supply not to be turned on. At this point, the freezer compartment of the refrigerator will not be cooled.

It is necessary to check if the light in the refrigerator is on to determine if the power of the refrigerator is turned on.

2. The voltage is too low: If the voltage is too low, it will affect the function of the refrigerator. Usually, the voltage of the refrigerator is 187 volts. The compressor of the refrigerator below 187 volts cannot start properly and effectively, and the cooling effect is naturally not good.

3. Low ambient temperature: The ambient temperature also affects the refrigeration of the refrigerator. When the ambient temperature is lower than the normal starting temperature of the temperature slag roundness controller, the refrigerator's thermostat will not start properly. The temperature can only be maintained when the cryogenic switch is turned on. The controller is forced to start.

4. The set temperature of the refrigerator is not reached: The temperature of the refrigerator is determined by the refrigerator thermostat, so if the temperature of the refrigerator does not meet the set requirements, it will not be shut down, and the freezer may cause the refrigerant to limit the cooling temperature. It is also impossible to rule out that the air cooling fan is broken, and too many items in the refrigerator will block the air outlet, resulting in poor cooling effect.

5. Refrigeration system leakage: A leak in the refrigeration system means a leak in the refrigerant. Although the refrigerator is still running, there is no refrigerant in the system, and it cannot absorb heat through evaporation, so the temperature of the refrigerator in the refrigerator does not decrease.

6. There are many items in the refrigerator, such as Zen collapse: There are many items in the refrigerator, and the refrigeration temperature is not set enough, which will make the refrigerator in the refrigerator not cool. At this time, the temperature of the refrigerator should be turned down. Note that the higher the temperature controller, the lower the temperature, the higher the number in summer and the lower the number in winter.

7. Compressor problem: The problem of the compressor in the refrigerator will also cause the freezer compartment of the refrigerator to not cool. Check if the compressor pressure is too high. If it's too low, there will be problems with the compressor.

8. If the fan does not work, the cold air will not enter the refrigerator room, and the refrigerator will not be cooled. If the fan is damaged, it needs to be replaced in time.

Summary. Dear Glad your question, the reason why the refrigerator refrigerator is not refrigerated is as follows: the refrigerant in the refrigerator refrigeration system is insufficient, and the refrigerant needs to be replenished in this case.

2. The capillary tube of the refrigerator is blocked, which will also cause the refrigerator to not refrigerate. 3. The fan of the refrigerator is also very important for refrigeration, if the fan does not work, it will also lead to the situation that the refrigerator room is not refrigerated. 4. It may be that the connection of the power supply is not normal, and the refrigerator will not be refrigerated if the power supply is disconnected.

5. If the compressor is not running normally, if the high-pressure output buffer pipe in the compressor is broken, resulting in the high-pressure pipe not exhausting and the low-pressure pipe not suctioning, then the compressor will run but not refrigerated. Personally, I think most of the failures are due to leaks in the refrigeration system and all the refrigerants are exhausted. Although the compressor is running, there is no refrigerant evaporation and heat absorption, so the temperature inside the refrigerator does not drop.

Solution: Listen carefully for liquid flow in the copper tube. If not, it indicates a leak of refrigerant in the system, or the compressor is incapacitated. Then you have to report for repair.

That's all for me, I hope mine can help you.

Xiang finger. Good. Thank you.

It's okay dear. Refrigerant go to ** buy.

Refrigerants can be purchased online, usually sold in shopping apps on your mobile phone or sold in offline air-conditioning refrigerators.

Buy it back and put it in**.

It is recommended that you eliminate the problem first, do not draw conclusions too early, and avoid working for half a day is not this problem, such as clearing the hole fruit you don't understand very well or it is recommended that you ask the after-sales service to repair it.

When I bought it, I bought it more than ten kilometers away, and people don't know if they will come over so far.

You can discuss with the other party, after all, you are the other party's customer, and the other party will definitely give you a pro to solve the after-sales problem.

It depends on whether the refrigerator is directly cooled or air-cooled, and how does the compressor work?

If it is a direct-cooled refrigerator, the compressor always works without stopping, but it does not refrigerate or the refrigeration effect is poor, and the temperature of the refrigerator is high, it should be a pure disorderly damage and leakage phenomenon at a certain position in the system pipeline, resulting in the loss of refrigerant.

Over time, the refrigeration effect of the freezer compartment of the refrigerator will slowly decrease until it is no longer cooled, but the compressor will always work more than shut down.

If the connecting pipe behind the refrigerator is damaged and leaking, it can be repaired by direct welding and plugging, and then vacuuming and fluoridation.

If the condenser leaks, it can be repaired by using a rear external condenser.

If it is an anti-dew pipe leakage, it can be discarded, so that it does not affect the refrigeration, but in rainy and humid weather, the refrigerator door frame will be made around the stall to produce condensation, which is prone to rust after a long time.

If it is a leak in the refrigerator, it can be repaired by recoiling the copper pipe.

But if it is a leak in the freezer, there is no need to repair it, because the repair must be too high, it is better to buy a new refrigerator.

If it is an air-cooled refrigerator, if there is no problem with the refrigerator fan, it is estimated that the performance of the automatic defrost circuit is abnormal, and the defrost electric heater is damaged, resulting in a large amount of frost accumulation and blocking the air duct of the refrigerator.

It is recommended to contact after-sales service or ask a professional for maintenance.
