in winter, it is most appropriate to set the refrigerator to the 4th to 5th grade. There are 7 gears in refrigerator 1 * *, and we can adjust the gears according to different seasons. The larger the gear number, the greater the refrigeration intensity of the refrigerator. In spring, the gear can be adjusted to 2~3, and in summer, it can be adjusted to 1~2. In winter, it is adjusted to the middle and high grade because the ambient temperature is low, and the compressor will start slowly when the gear is in the low grade, leading the refrigerator to melt ice in the freezer.

The switch for adjusting the gear position of the refrigerator is the thermostat, and its working time and power consumption are greatly affected by the ambient temperature, so we need to choose different gears to use in different seasons. The thermostat of the refrigerator should be turned on at low gear in summer and at high gear in winter.

when the ambient temperature is high in summer, it should be used in the weak gear 2 and 3, and when the ambient temperature is low in winter, it should be used in the strong gear 4 and 5. The reason is that if the ambient temperature is high in summer, if the temperature in the freezer is set in the strong gear (4 and 5), it will reach below -18℃, and the temperature difference between inside and outside will be large, so it is difficult for the temperature in the freezer to drop by 1℃.

if you change to the weak gear (2nd and 3rd gear) at this time, it will obviously shorten the starting time of the refrigerator, reduce the wear of the compressor and prolong the service life. Therefore, when it is hot in summer, the temperature control should be adjusted to weak gear, on the contrary, it should be adjusted to high gear in winter.
