Refrigerator Maintenance

Frost is a poor conductor, conductivity is Al 1/350, frost-covered surface of the evaporator, as food in the evaporator box between the insulating layer, affecting heat exchange between the evaporator and inside the food so that the temperature inside the box does not fall, lower freezer refrigeration performance, increased power consumption, even the compressor runs for a long time to heat up, easily burned out compressor.
