Failures of refrigerators are a consequence of improper use, incorrect installation or physical wear and tear of technical units. Many modules can be repaired by yourself, for example, changing the thermostat or seals. Larger scale repairs, say, replacement of freon or capillary system, should be trusted only to competent craftsmen, who not only correctly identify the cause of the defect, but also are able to fix it, using specialized equipment. Also, only specialists can carry out comprehensive maintenance of refrigeration equipment.
