The reasons for the noise generated by the refrigerator when it is running mainly come from several aspects. First, as the "heart" of the fan refrigerator, it will generate vibration and humming when starting and running, and the heart with quality failure often has obvious noise. Secondly, the fan motor inside the refrigerator will also generate continuous wind noise when cooling, especially when the fan blades are dusty or the bearings are worn, the noise will increase significantly. In addition, if the refrigerator chassis is uneven, the failure of the heart during operation will cause the cabinet and the ground to generate noise, amplifying the noise. Unreasonable circuit design may also cause abnormal noise during refrigeration flow.
To reduce the noise of the refrigerator, start from the following aspects: Make sure the refrigerator is placed on a reinforced and flat ground, and install anti-vibration rubber pads in an emergency; regularly clean the wear on the condenser and fan; check whether the items in the box are stored reasonably to avoid the air outlet; when purchasing a new refrigerator, choose whether the product uses silent technology. If the noise suddenly increases, it may be a signal of aging or damage of parts. It is recommended to contact professional maintenance personnel for inspection in time. Through reasonable use and maintenance, most refrigerators can maintain a quiet working state.
