Generally, there are seven gears on the knob, and the numbers from 0 to 7 indicate different temperature gears. 0 is non-working, and the larger the number, the stronger the refrigeration. In order to adapt to the indoor temperature and reduce the temperature difference between the inside and outside of the refrigerator, when it is cold indoors in winter, the refrigerator is set to 4-6 grades; When the indoor temperature is high in summer, the refrigerator should be set to 1-3 and 3-4 in spring and autumn.
If you use an artificial intelligence refrigerator at home, you don't need to set it yourself. The refrigerator will automatically adjust the temperature of the cold room. If artificial intelligence is not turned on, use the artificial intelligence button to make the refrigerator enter the artificial intelligence state.
Of course, many artificial intelligence refrigerators can also be adjusted manually. The temperature of the refrigerator is between 3℃ and 7℃. Adjust the temperature to about 7℃ in summer. If the temperature is too low, in order to meet the temperature requirements, the compressor will be started frequently, which will not only waste electricity, but also shorten the service life of the refrigerator.

Common faults of refrigerator:
Fault symptoms: the refrigerator is cold inside and hot outside.
1. The high-pressure pipes on both sides of the refrigerator cause heat outside the refrigerator.
When designing the refrigerator, high-pressure heat pipes were buried on both sides of the refrigerator for beauty and convenience of cleaning. Because the high-pressure heat pipe is hot, it is normal for both sides of the refrigerator to heat up.
2. The heat outside the refrigerator is caused by the operation of the compressor.
The refrigerator is cooled by compressor and frozen by circulating freon. When the refrigerator compressor is running, Freon circulates and the radiator takes away heat. The radiator of the old refrigerator is exposed. You can see a row of black pipes behind the refrigerator. Now the refrigerator is built in for beauty. You can't see it, but you can still feel the heat, so it's very hot outside the refrigerator.
3. The heat emitted by the running refrigerator leads to the heat outside the refrigerator.
You should know that any substance will give off heat after liquefaction and absorb heat when it is gasified. This is the most common physical phenomenon. Air-conditioned refrigerators use this principle to liquefy refrigerants and release heat, and then let them evaporate and absorb heat.
The position where liquefaction heat is released and the position where evaporation absorbs heat cannot be in the same place, otherwise it will not work. In the refrigerator, the radiator is outside the refrigerator. The purpose is to dissipate heat, but you can still feel it when you dissipate heat, so it is hot outside the refrigerator.
