What is the best temperature for general refrigerator freezing? .

Below minus 18 degrees, but the temperature of the refrigerator can be adjusted by itself, so it is appropriate to adjust it to minus 18 degrees.

Generally, there will be an adjustment button 1-7 in the freezer. The button can be set to 2-3 in summer and 6-7 in winter, mainly because the outside temperature will affect the performance of the refrigerator. This differential displacement makes the inside and outside of the refrigerator have a good integration. Generally speaking, the temperature of the refrigerator is kept at about 5-8 degrees.

Extended data:

The temperature control button of the refrigerator will be marked with a number representing the control range of the internal temperature of the refrigerator. The nominal figure of refrigerator temperature adjustment refers to the refrigeration intensity of refrigerator, so the larger the displayed figure, the lower the temperature. The zero gear is standby. When the compressor is not working, the seventh gear is the lowest temperature. There is a temperature sensor in the cold room of the refrigerator. The higher the outside temperature, the greater the difference with the temperature inside the refrigerator. In winter, if the thermostat doesn't feel the temperature difference, it is necessary to jump up the number, usually 6-7.
