How to adjust the temperature of refrigerator freezer?

How to adjust the temperature of refrigerator? Refrigerator is a very common household appliance, which is used by almost every household now. The temperature in the refrigerator is very important, especially in the freezer. How to adjust the freezing room temperature?

How to adjust the temperature of the freezer 1 The refrigerator thermostat is installed on the inner wall of the refrigerator. When the user rotates the temperature control knob to determine the temperature range, the contact of the temperature controller will be closed or opened to control the operation of the compressor to reach the predetermined temperature. Specifically, when the temperature is higher than the predetermined temperature 1- 1.5 degrees, the contacts can be closed to make the compressor run for refrigeration. When the temperature is lower than the predetermined temperature 1- 1.5 degrees, the contact shall be disconnected and the compressor shall be stopped.

Some temperature controllers are marked with quick freezing position. When the temperature control knob is turned to this position, the contacts are closed and are no longer controlled by temperature. At this time, the compressor will not stop and continue to cool. If you can't achieve the desired effect, you can adjust it according to the situation.

In addition, adjusting the thermostat depends on the season. Don't turn the thermostat knob to the low position in summer, and don't turn the thermostat knob to the high position in winter, because the higher the gear, the faster the temperature drops.

Refrigerator temperature

Single-door refrigerator: only the cold room, no freezer. This kind of refrigerator appeared early and has been eliminated by the market now. The refrigeration temperature of the refrigerator is 0-5 degrees, and the effect is not bad.

Double-door refrigerator: the upper layer of the refrigerator is the refrigerating room and the lower layer is the freezing room. Because the cold air inside will sink after circulation, the temperature at the bottom is lower than that at the top. Usually the temperature of this kind of refrigerator is 0-5 degrees.

Three-door refrigerator: the refrigerating room is located on the upper and lower floors, and the middle floor is the freezing room. The upper refrigerating chamber is mainly used for storing meat and food, and the lower refrigerating chamber is mainly used for storing vegetables and fruits. The upper and lower evaporators are plate-type and rely on natural convection to complete temperature exchange.

Opposite refrigerator: the left is the refrigerating room, and the right is the freezing room. As soon as the door is opened, the cold air is easy to leak out, which consumes a lot of electricity and needs constant cooling. Usually after refrigeration, the temperature in the box is 0-5 degrees.

Freeze in the freezer

Ordinary refrigerators are single-door structures, and most of the space in the refrigerator is a cold room. Usually the temperature is controlled below 10 degrees. Only there is a freezer above the refrigerator, and the temperature is controlled between-18 degrees and-15 degrees, which can quickly freeze ice cubes and store low-temperature items and food.

This refrigerator has only one evaporator, so the refrigeration effect of the refrigerating room actually depends on the change of the specific gravity of the air in the upper and lower parts of the whole room, and the air in the refrigerator forms a natural convection cycle to cool the stored food.

There is an evaporator in the freezer above the refrigerator, which can put the ice box. There are many shelves under the freezer, on which fruit boxes, meat boxes and water boxes can be placed.

There is also a row of shelves in the refrigerator door, which can be used to place eggs, bottles, cans and so on. , easy to take. In order to facilitate observation, there is also a lighting lamp in the refrigerator, which is directly controlled by the micro switch. When opening the door, the lighting is on, and when closing the door, the lighting power supply is cut off.

If the freezer freezes, it is necessary to investigate the cause, because this is not a normal phenomenon and will affect the storage of food. Some people don't pay attention when there is little ice, but they should pay attention once there is more ice to avoid freezing food and causing adverse effects.

What if the refrigerator freezes?

If there is a thick ice layer inside the refrigerator, deicing measures should be taken immediately. Unplug the power supply, cut off the power supply, open the door of the box, take out all the food, then let the ice melt naturally and clean it up. You can also shovel directly with a deicing shovel, but be careful not to damage the refrigerator liner. Some people put a glass of water in the refrigerator to accelerate the melting of ice.

If the drain pipe of the refrigerator is blocked, which leads to freezing, under normal circumstances, the foreign bodies in the drain pipe should be cleaned first to make the drainage return to normal, and then the ice cubes in the refrigerator should be cleaned. If there are too many foreign bodies in the drainage tube, it should be opened with a thin flexible tube. Remember to operate in the case of power failure, otherwise safety accidents will occur and endanger your own safety.

If the temperature of the refrigerator is set too low, resulting in freezing, it is usually easy to deal with, and the fault can be eliminated by adjusting the thermostat gear to the correct position. In addition, measures have been taken to remove the ice on the inner wall and make it return to normal. In order to avoid similar situations in the future, remember not to adjust the thermostat at will.

How to adjust the temperature of refrigerator freezer 2 What are the reasons for the freezing of Haier refrigerator freezer?

The humidity in the freezer of Haier refrigerator is high, and the outer surface temperature of the evaporator on the inner wall of the freezer is very low when working, so the air moisture in the freezer gathers on the back wall of the freezer and condenses into ice beans or frost. When Haier's refrigerator stops working, because the temperature of the freezer rises, frozen beans or frost can turn into water and flow out of the water outlet, so this situation is normal. In summer, because of the high temperature and humidity, the frosting of Haier refrigerator freezer will be heavier.

One of the reasons why the freezer of Haier refrigerator freezes is that the constant temperature gear in the freezer is not adjusted correctly, which is similar to the situation of running water in the freezer. If the gear position is not adjusted properly, it is easy for the freezer to run out of water or it will be frozen. Nowadays, the higher the thermostat number, the lower the temperature. It is recommended to adjust the thermostat gear to 4th gear.

The second reason why the freezer of Haier refrigerator is frozen is that the thermostat in the freezer is abnormal, or there is a problem, and the temperature change cannot be accurately sensed, which makes the freezer of Haier refrigerator freeze bigger and bigger. At this time, it is enough to change a thermostat as needed.

There are three reasons why Haier's refrigerator freezes: the food in the refrigerator is placed in the back, close to the inner container at the back. If the condenser of Haier refrigerator is two-sided, there will be ice on the back of the refrigeration pipe. Pay attention to cold food not completely close to the back of Haier refrigerator, so as to avoid freezing of Haier refrigerator freezer.

The fourth reason for the freezing of Haier refrigerator is that the refrigeration pipe on the back of Haier refrigerator is too close to the gold lining, which leads to freezing. If this is the case, only professional maintenance personnel can be invited to check and repair.

What should Haier do if the refrigerator freezes?

1. First, let's see if there is a low temperature compensation switch in Haier refrigerator. Turn on the low temperature compensation switch when the indoor ambient temperature is lower than 16 degrees, and turn it off when the indoor ambient temperature is higher than 16 degrees. Otherwise, when the indoor environment temperature rises, the internal running time of Haier refrigerator is too long, which will lead to shutdown. After working for a long time, the refrigerator will frost too much, so it is necessary to adjust the low temperature compensation switch.

Secondly, see if the door sealing strip of Haier refrigerator can be intact. If the seal of the sealing strip is broken, the cold air in the refrigerator will easily leak out. In addition, when the temperature sensor inside Haier refrigerator senses that the temperature can't reach the required temperature, the compressor starts to operate, and the operation time is long, and there will be too much frost in the cold room of Haier refrigerator.

I can do the test at home. In the evening, I turn on the flashlight in the freezer of Haier refrigerator, then close the door of Haier refrigerator, and finally turn off all the lights at home. If the light source can be seen by the refrigerator door of Haier refrigerator, it proves that there is something wrong with the sealing strip of Haier refrigerator.

3. Thirdly, see if the water outlet hole at the bottom of the inner wall of Haier refrigerator can be blocked by foreign objects. After the outside temperature rises, the temperature difference between the inside and outside of Haier refrigerator increases, and doors are frequently opened. The frost on the inner wall of Haier refrigerator will turn into water. If it cannot be discharged from the water outlet in time, it will lead to frost, which can be treated with the through-hole pin provided by Haier refrigerator.

Finally, the most traditional way is to unplug the power supply after seeing the freezer of Haier refrigerator freeze. After the freezer of Haier refrigerator freezes, wipe the water droplets in the freezer with a dry cloth and plug them in after a while. Everything is settled.

However, this can only be solved in a short time. If Haier refrigerator is not used properly, it is still very easy to cause the freezer to freeze. If you want to completely solve the freezing phenomenon of Haier refrigerator, you must find Haier's after-sales careful maintenance.
