Question 2: How to keep the refrigerator from freezing?
First, try to reduce the number and time of opening the refrigerator;
Second, the refrigerator door must be closed tightly to prevent air leakage;
Third, there should be a certain gap in the refrigerator to put food. Try not to get close to the back wall of the refrigerator liner. Foods with high moisture content are best sealed with plastic wrap.
Fourth, pay attention to whether the drain is blocked by dirt. If it is blocked, it should be unblocked in time.
Five, in addition, refrigerator users should also pay attention to adjust the thermostat gear or temperature setting according to the temperature change, which is generally 5-7 in winter (temperature 2-4℃) and 1-3 in summer (temperature 6-8℃). The problem that there is frost in the freezer and there is nothing in it may be because the temperature range is too high.
Question 3: Why doesn't the refrigerator freeze? Hello, I think a little lack of refrigerant and fluoride can solve the fundamental problem. You can try to set the thermostat to the maximum position and work for a whole day to see if it is covered with frost. If it's still the same, you can add refrigerant directly as I said before. Secondly, the possibility of insufficient compressor exhaust is very small, but it is not ruled out. I hope you can solve the problem smoothly and wish you success.
Question 4: How to keep the refrigerator from freezing? You mean the freezer is frozen? Or the freezer?
If it is a cold room, maybe your temperature is not well adjusted and the refrigeration is too strong. You can adjust the temperature knob of the refrigerator according to the instructions to raise the temperature to about 6℃.
If it is a freezer, almost everything will freeze except frost-free ice, and the frozen water usually comes from air, so you can only try to reduce the time and frequency of opening the refrigerator door, and put less items with more water and high temperature in the refrigerator, maybe a dozen bags of moisture-proof beads will do. Then regularly remove the ice crystals in the refrigerator. If you want to avoid freezing completely, unplug the power supply and stop using the refrigerator, so it won't freeze.
Question 5: What if the refrigerator doesn't freeze? Does it still work? 1. If the refrigerator has no refrigeration, the first thing to consider is whether the power connection is normal. If that's the reason, that's the best way. Plug it in and it's done.
2. Check whether the refrigerator door is closed. If the refrigerator door is not closed properly, the air conditioner will run away, and the things in the refrigerator will naturally not freeze. Close the refrigerator door.
3. If the power supply is connected normally and the refrigerator door is closed, but the refrigerator is still not cooling, check the compressor of the refrigerator. If the compressor is normal, there will be a slight sound that normal people can hear, and there will be a slight vibration. If it is abnormal, only the compressor can be repaired or replaced.
4. If the refrigerator compressor works normally, unplug it, and then listen to whether there will be a sound like water flowing in the copper tube of the refrigeration system. If you hear this sound, it means that there is something wrong with the refrigerant in the refrigeration system of the refrigerator, which means that the compressor can no longer serve the refrigerator normally.
In addition, if we store too many things in the refrigerator, it may also cause the illusion that the refrigerator is not cooled. Try to slim down the refrigerator and say it works normally.
6. After the refrigerator works for a long time, there will be a thick box on the box wall. If this box is left untreated for a long time, it will also affect the refrigeration effect of the refrigerator.
Question 6: What if the refrigerator is not frozen?
Sometimes it's not the use or quality of the refrigerator. Maybe it's your power supply. Check whether the power connection is normal. Open the door of the box, observe whether the lighting in the box is on, or test whether your socket has electricity with an electric pen.
Compressor problem
If the power connection is normal, listen to whether the compressor works. When the compressor works normally, it will make a slight vibration motor sound (if you feel the vibration of the compressor with your hands, be careful not to burn it, because the temperature of the compressor is 40-50℃ in winter and 80-90℃ in summer).
Is the refrigerant leaking?
If the compressor can work, judge whether there is refrigerant in the refrigeration system. Let the refrigerator run for a few minutes, and then unplug it. Listen carefully to the sound of liquid flowing in the copper tube. If not, it means that the refrigerant in the system has leaked or the compressor has lost its working ability.

Fan problem
If the refrigerator is of indirect cooling type, check whether the fan works. Open the door of the freezer, press and hold the button on the edge of the box mouth by hand (this button controls the indoor lighting when opening the door and stops the operation of the fan) to see if the fan works. If the fan doesn't work, the refrigerator won't cool. In addition, too much food will also affect the cooling effect.

Influence of external temperature
The freezing chamber may lead to the extreme refrigeration temperature of the refrigerant. This phenomenon mostly occurs in air-cooled refrigerators. The reason is that the evaporator frost in the refrigerator is broken, which leads to ice jam. It is not excluded that the air-cooled fan is broken and the air outlet is blocked by too many items in the refrigerator, resulting in poor cooling effect. The temperature of the refrigerating chamber of the direct-cooling refrigerator is automatically adjusted with the adjustment of the freezing chamber temperature, and the freezing chamber temperature can be reduced. Generally, it is normal that the refrigerator temperature is 4- 10 degrees. Note that the larger the thermostat number, the lower the temperature, the larger the summer number and the smaller the winter number. In addition, the refrigerator door is often opened, and there are many items in the refrigerator, which leads to the refrigerator being unable to cool or the cooling effect is not ideal.
Question 7: Is the refrigerator frozen? What happened? There are several reasons why the refrigerator is not frozen: 1. The compressor is not stopped, and the refrigerator is not frozen. The reason is that the refrigerator doesn't cool because the freon in the pipeline leaks, or the compressor itself is broken, resulting in insufficient cooling capacity. 2. The compressor doesn't work because the thermostat is broken, the compressor starter is broken, the overheat protector is broken or there is something wrong with the power supply. The compressor itself can be broken, but the compressor is rarely broken. You can check whether the compressor is working. If you keep working, the first reason is that there is no heat dissipation, and maintenance is more troublesome. It is necessary to check the leakage or replace the compressor. If the compressor doesn't work, it won't cool, which is the second reason. This is a circuit problem that is easy to maintain.
Question 8: What's wrong with the freezer? For the direct-cooling refrigerator, when the refrigerator is in working condition, the back of the refrigerating chamber will freeze. There is an evaporator on the back of the inner container of the refrigerating chamber, and the temperature of the refrigerating chamber mainly depends on the evaporator to reach the set temperature. When the refrigerator compressor stops working, the temperature will rise. At this time, the ice on the back of the refrigerator will melt and become water droplets, which will drip down the back to the water outlet and then evaporate in the evaporating dish. Due to the opening times, the improvement of environmental temperature and humidity, the inaccurate control of food humidity and temperature, and the wrong setting mode (the low temperature compensator is turned on in "winter"), the ice and water behind the refrigerator cannot melt and flow out in time, and will freeze when working again.
The main reasons why the refrigerator does not freeze are as follows:
Power supply problem. Sometimes it's not the use or quality of the refrigerator. Maybe it's your power supply. Check whether the power connection is normal. Open the door of the box, observe whether the lighting in the box is on, or test whether your socket has electricity with an electric pen.
Compressor problem. If the power connection is normal, listen to whether the compressor works.

Whether the refrigerant leaks. If the compressor can work, judge whether there is refrigerant in the refrigeration system. Let the refrigerator run for a few minutes, and then unplug it. Listen carefully to the sound of liquid flowing in the copper tube. If not, it means that the refrigerant in the system has leaked or the compressor has lost its working ability.

Question 9: Why doesn't the refrigerator freeze? The refrigerator is not frozen, which is mainly related to fluorine leakage, compressor and thermostat.
