The larger the number of thermostat knobs in the refrigerator, the lower the set temperature and the longer the refrigeration time of the compressor.

When it is adjusted to the maximum end, which is the non-stop point of the thermostat, the refrigerator will work continuously. If it is the knob of 1 to 5, it is generally selected at 1 to 2 in summer, 3 in spring and autumn, and 4 to 4.5 in winter. If there is a temperature compensation switch, when the room temperature is lower than 15 degrees, turn it to the "on" position. The temperature is between 15 and 19 degrees, just choose 3 to 4.

0 means off, and 5 means coldest. If you are in a coastal area, your refrigerator should be set like this, 3 to 4 in summer and 1 2 in winter. If you are in the mainland, such as Sichuan, your refrigerator should be set like this, 2 to 3 in summer and 3 to 4 in winter.

Generally, when the refrigerator is used for the first time, the thermostat knob should be set to the number 1, and then the knob should be set to the middle number after the refrigerator works for a period of time. After about 2 hours, the temperature in the refrigerator has stabilized.
