When the refrigerator freezer reaches minus 20, the temperature no longer drops, what s going on, th

The freezer compartment of the refrigerator is severely frozen.

Superintendent Shao Hongyi.

1. The moisture in the refrigerator is relatively large, and the temperature of the inner wall of the refrigeration refrigerator is low, and the water vapor in the refrigerator will condense into frost or ice when it encounters the colder inner wall. 2. The drainage hole in the freezer compartment of the refrigerator is blocked, resulting in the defrosting water cannot be discharged smoothly out of the refrigerator, and the defrosting water freezes when the refrigerator cools down again. 3. The poor sealing of the refrigerator causes the water vapor in the air to enter the refrigerator, and the water vapor will freeze when it encounters the colder inner wall.

Solutions to freezing in the refrigerator freezer 1. Shut down the power regularly, open the refrigerator door to let the ice and frost melt naturally, and then wipe it with a rag to dry. 2. Check whether the drainage hole of the refrigerator can smoothly discharge the defrosting water, if not, you can add some hot water to the drainage hole to see if the drainage outlet is frozen and blocked, if it can't be solved, poke it with a thin wire. 3. Check whether the sealing of the refrigerator is good, you can test whether the door seal has suction power when opening the freezer, and whether there is dirt in the gap of the door seal that affects the sealing, and it is best to check and clean the door seal every other time.

Household refrigerators are generally set to minus 18 degrees at the factory, which is no problem for refrigerated food, if the temperature machine is still running, the refrigerator is cold and closes the door, or the box is not well sealed, quickly clean the sealing strip on the door.

After the refrigerator freezer is frozen to 20°C, it can no longer be cooled. This should be the refrigerator's own regulations, in fact, minus 20° should be able to play a good role in protecting the food, so that the food will not be corroded. So there is no need to lower the temperature again.

Look at how many stars the fridge is.

If the temperature setting of the freezer is correct, but the temperature in the freezer is only minus 2 degrees, it depends on how the compressor is working?

If the compressor does not stop working, it is estimated that the refrigerant is lost due to a breakage and leakage at a certain location in the system pipeline.

If the compressor starts and stops normally, it may be caused by abnormal performance of the control circuit or a faulty solenoid valve.

Abnormal performance of the automatic defrost circuit of an air-cooled refrigerator or damage to the defrost electric heater can also cause too much frost to accumulate and obstruct ventilation.

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

There are several possible reasons why the freezer compartment of the refrigerator is only minus 2 degrees:

Thermostat failure: The refrigerator's thermostat is responsible for controlling the temperature throughout the freezer compartment and freezer, and if it fails, it can cause the freezer compartment temperature to be too low. You can check if the thermostat is working properly.

Check the thermostatic pipes: The thermostatic pipes in the refrigerator can control the temperature in the freezer compartment, and if the thermostatic pipes are damaged or blocked, the freezer temperature will also be too low.

Fluoride leakage in the condensation pipe: If there is a fluorine leak in the condensate pipe, the temperature inside the freezer will become too low.

The ambient temperature is too low: If the ambient temperature is very low, such as in the cold winter season, the refrigerator will not be as good as in other seasons. At this point, you don't need to repair the refrigerator with a vertical machine, but you should place it in a warm room and keep the kitchen properly ventilated.

The freezer compartment of the refrigerator is only minus 2 degrees Celsius, which may be caused by the following reasons:

Improper temperature regulation: If you set the thermostat too high, or if the ambient temperature is high (e.g., during the summer season), the temperature in the freezer may be affected and the desired low temperature may not be achieved.

Internal Failure or Damage: If there is some internal failure or damage in the freezer, such as blocked freezing pipes, damaged compressors, or refrigerant leakage, it may cause the freezer to not reach the expected low reed temperature.

Excessive use: If your refrigerator has been used for a long time and has exceeded its design life, its performance and cooling effectiveness may gradually deteriorate, resulting in the temperature inside the freezer compartment not reaching the expected low temperature.

In view of the above situation, it is recommended that you take the following measures to solve the problem:

Adjust the temperature: adjust the temperature of the refrigerator and freezer according to the actual situation, and the temperature setting of the freezer can be appropriately increased.

Check for faults: If there is a suspicion of internal faults or damage, it is recommended to contact a professional electrical repair service for inspection and repair.

Replace your old refrigerator: If your refrigerator has been used for a long time and has exceeded its design life, it is recommended to buy a new refrigerator to ensure the effectiveness and quality of use.

Normal. From the perspective of refrigerator design, it is impossible to fix the temperature of a cabin at a point, if so, it cannot be controlled, the regular thing is, if it is set at -18 degrees, it may stop at -20 degrees, and turn on at -16 degrees, there is a temperature difference.

But the display design is unchanged, it's all -18. Most of the problems in your fridge are when the refrigeration temperature is too high, or a lot of stuff is put in. If the refrigeration time is too long, the refrigerant will have to flow back from the freezer, which may also be reduced, which is fine, after a while, the freezer will return to normal, don't worry.

Attention should be paid to the following when using the refrigerator:

1. Keep away from heat sources and keep gaps.

For every 5 percent increase in the temperature around the refrigerator, the inside of the refrigerator increases by 25%. Therefore, it should be placed away from heat sources as much as possible, and it is better to ventilate and shade the place. The distance between the refrigerator and the wall should be at least 10cm.

2. Do not put hot food directly in the refrigerator, and put it in when it reaches room temperature. The food in the freezer is best packaged in plastic bags, which can be frozen quickly, which is not easy to dry out, and prevents moisture from turning into frost.

3. The food should not be too full, and there should be a gap between the food and the refrigerator wall to facilitate the flow of cold air.

4. Before turning on the power of the refrigerator, check whether the voltage used by the refrigerator on the nameplate of the refrigerator is consistent with the voltage at home, and at the same time, arrange a separate socket for the refrigerator, and do not use the same socket with other electrical appliances.

You have to look at the original 18 degrees is the refrigerator freezer setting temperature or the actual temperature, and then check what the setting temperature is, if the setting temperature is 18 degrees, it will definitely not be normal.

I think plus or minus two degrees are normal, just fine-tune it.

There are positive and negative differences, which have been determined at the time of design.

When the ambient temperature is high in summer, it should be used in 2-3 gears of weak gear.

Reason: In summer, the ambient temperature is high, and at this time, it is difficult for the temperature in the box to drop by 1 degree, and the loss of cooling through the box insulation layer and door seal will also be accelerated, so that the start-up time is very long and the downtime is very short. Therefore, when the temperature is high in summer, the thermostat is set to a weak setting.

2. In winter, the general gear should be played to more than 4 gears.

The reason is: the purchased product has only one refrigerator room thermostat to control the temperature of refrigeration and freezing, under normal circumstances, if the ambient temperature is lower than 16 degrees, adjust to 5 gear, below 10 degrees, you can adjust to 6 or 7 gear. Sometimes because the ambient temperature is too low, such as 0 5 degrees, the gear is lowered and the frozen things are refrigerated, at this time, it is completely possible to store the food outside the refrigerator.

3. The recommended temperature for the fresh food area is -15 in the freezer. If there is a separate freezer for long-term storage of food, it is best to keep it at a temperature of -17. For example, the refrigeration temperature of fresh meat and fish is about -1 degree, the refrigeration temperature of eggs and milk is about 3 degrees, and the refrigeration temperature of vegetables and fruits is about 5 degrees.

1.The voltage is too low, the refrigerator compressor can not start Generally, the voltage of the refrigerator is 187V-242V, if the voltage at home is lower than 187V, the refrigerator compressor can not start normally, which is also the reason why the refrigerator is not refrigerated.

2.The temperature of the refrigerator does not reach the temperature required by the thermostat The refrigerator thermostat is generally installed in the refrigerator, and the temperature of the refrigerator is not reached.

3.Compressor Problems The compressor's internal high-pressure output buffer pipe is broken, or the screws holding the pipe loose, will cause the high-pressure pipe to not vent.

4.Refrigeration System Problems There is a leak in the refrigeration system, causing all the refrigerant to run out, and the compressor of the refrigerator is running, but inside the system.

If the temperature of the freezer can reach -10, it means that there is no major problem with the refrigerator itself, and it may be because there are a lot of frozen things. If the temperature of the freezer does not drop for a long time, it means that the refrigerator itself may have the cause of fluoride leakage.

Don't ask the reason, give the after-sales service ** repair, I'm really helping you look forward to it,

1) Analysis of the reasons why the refrigerator refrigerator is not refrigerated:

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 runs with a large head beam, it is not refrigerated.

2. Refrigeration system leakage, refrigerant.

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.

The temperature in the refrigerator does not drop. erected.

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. First find out the slag residue in the leakage part of the system, 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 rated temperature in the refrigerator is prevailing.

3. The capillary tube or dryer is blocked, and the outlet is heated.

For this reason, it is necessary 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.

Insufficient compressor exhaust pressure: 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.

The power is not connected: Open the refrigerator door and check whether the light in the box is on to determine if the power of the refrigerator is on. If the light is not on, check whether there is electricity in the power socket with a pen or multimeter and whether the power plug of the refrigerator is well plugged in.

Because the power supply is not plugged in, the refrigerator cannot be refrigerated normally, as long as the power supply is plugged in.

Temperature; In addition, the ambient temperature of the refrigerator is too high, the temperature of the food is too high or too much, and the frost in the freezer is too thick, which will also cause the temperature to not drop, etc., all of which will cause the temperature of the freezer room to not drop.

The temperature of the refrigerator freezer can't be lowered, according to your treatment, you should first see whether the ice on the back wall of the refrigerator is all or partial, if it is a part, it means that the refrigerant is leaking.

Observe the boot time again, if the boot time is very short and the downtime is too long, you can adjust it. If it doesn't stop, it's still faulty.

My refrigerator is insulated, and the temperature of the refrigeration is just right, but the freezing temperature has not been able to drop, what is going on?

The freezing temperature of the refrigerator cannot be reduced, either because the refrigerator runs out of refrigerant, or because the refrigerator refrigerant leakage will also cause the freezer compartment of the refrigerator to not refrigerate. If the refrigerant runs out or leaks, the compressor cannot use the refrigerant in time to work in normal work, and the freezer compartment of the refrigerator cannot be refrigerated normally, you can ask a professional to replace the refrigerant.
