The "jingle" sound of the refrigerator is often produced at the moment when the compressor starts or stops, sometimes it rings, sometimes it rings two or three times, and it will not affect its normal use. ;

If there is a "banging" metal pipe vibrating in the refrigerator compressor, it is the sound of the high-pressure muffler pipe cracking and should be repaired in time. ;

If there is a "boom" sound in the refrigerator, and the sound is made in the running refrigerator compressor, it is the sound made by the fracture or dislocation of the suspension spring in the compressor, which should be repaired in time;

The refrigerator makes a "giggle" or "click" sound accompanied by obvious compressor vibration. This is because the compressor parts are damaged or loose, causing impact and should be repaired in time. ;
