For the direct-cooling refrigerator, when the refrigerator is in working condition, the back of the refrigerating chamber will freeze. There is mainly an evaporator on the back of the inner container of the refrigerating chamber, and the temperature of the refrigerating chamber mainly depends on this evaporator to reach the set temperature. When the refrigerator compressor stops working, the temperature will rise. At this time, the ice on the back of the refrigerator will melt and become water droplets, which will drip down the back to the water outlet and then evaporate in the evaporating dish. Due to the opening times, the improvement of environmental temperature and humidity, the inaccurate control of food humidity and temperature, and the wrong setting mode (the low temperature compensator is turned on in "winter"), the ice and water behind the refrigerator cannot be melted in time and will freeze when working again.

Under special circumstances, please ask the service outlets to check the refrigerator temperature at the back of the refrigerating room when the refrigerator is started or stopped, so as to distinguish between normal and abnormal icing.
