The reason why refrigerators do not keep fresh
If the refrigerator wants to keep fresh, it can only operate in a certain environment. For example, if the surrounding environment is lower than 10 degrees, the compressor of the refrigerator will stop working, because when the outdoor temperature is lower than 10 degrees, there is no need to keep fresh the food in the refrigerator. If it is hard to keep fresh, then the winter temperature compensation switch and auxiliary switch are set on the temperature controller of the refrigerator. When the electric heater is turned on, the working environment of the compressor will return to normal state, so that it can work normally for refrigeration again.
