Refrigerators sometimes refrigerate normally, sometimes refrigerate abnormally, and even difficult to cool down, and the compressor keeps running for a long time. If the refrigerator is not used for a few days, it will be normal again when it is used again. This is due to a problem with the defrosting circuit, which prevents the evaporator from defrosting normally. When the frost layer on the evaporator becomes thicker, it blocks the circulation of cold air and reduces the heat absorption efficiency of the evaporator, making it difficult and difficult for the refrigerator to cool down. Long-term operation of the compressor.
