Choose different gears to use in different seasons. The refrigerator thermostat is low in summer and high in winter. When the ambient temperature is high in summer, it should be used in weak gear 2 and 3, and when the ambient temperature is low in winter, it should be used in strong gear 4 and 5.

In summer, the ambient temperature is high (up to 30℃). If the freezing room temperature is below-18℃, the temperature difference between inside and outside is large, and it is difficult to reduce the freezing room temperature by 1℃. Moreover, it will accelerate the loss of cold air through the insulation layer and door seal of the cabinet, so that the startup time is long and the shutdown time is short.
