The commonly used gear position of the freezer is 1-7. The freezer gear is set to 1-2 in summer, 4-5 in winter and 3 in spring and autumn. In short, the freezer is generally set at a low grade in summer, at a middle grade in spring and autumn, and can be raised a little in winter.

In order to keep the best fresh-keeping effect of the freezer, fresh fish, meat and other foods should be packed in plastic bags and stored in the freezer, while vegetables and fruits should be dried and placed in the lower part of the freezer, and the best storage temperature should be above zero. If you want to prolong the service life of the freezer, you should try to reduce and shorten the opening time and times.

Temperature represented by refrigerator 1-7.

The freezer 1-7 is a thermostat with a maximum temperature of 1 and a minimum temperature of 7. The control temperature of 1 gear is about 9℃- 10℃, which is also the highest temperature of refrigerator. Usually, when the indoor temperature exceeds 32 degrees in summer, the source needs to set this gear. The second gear temperature is around 8℃, which is also a common gear in summer.

The third gear temperature is 6-7℃, and the fourth gear temperature is about 5℃. These two gears are suitable for spring and autumn, and the indoor temperature is set at 20-25℃. The control temperature of the 5th gear is about 4℃, and that of the 6th gear is about 3℃. These two gears are generally set when the indoor temperature is lower than 15℃ in winter. The 7th gear is strongly cold, the temperature is generally around 2℃, and it is rarely set in this gear. Generally, a lot of food is put in the freezer. When refrigeration is urgently needed, set this gear, and the compressor will probably work all the time without stopping.
