The temperature adjustment function of Xiaoya brand small refrigerator is realized by seven gears: 123456, and each gear represents different temperature and compressor power. The larger the number, the stronger the freezing capacity of the refrigerator, and the lower the internal temperature. If the gear is selected as 0, the compressor will stop working and the internal temperature of the refrigerator will be consistent with the external environment.

These seven gears actually control the operation intensity of the compressor. As the number increases, the refrigeration efficiency increases, but at the same time, the power consumption will also increase. Specifically, gear 1 is the highest temperature setting in the fresh-keeping room, while gear 7 is the lowest freezing setting, which is suitable for foods that need to be frozen. When adjusting, users should choose the appropriate gear according to their needs to achieve the best effect of energy saving and food preservation.
