Problem with shock absorbers


The refrigerator also becomes noisy after a certain period of service, due to wear and tear in the shock absorbers. Most often they are rubber rings with a spring, which absorbs the vibration created by the motors. There are such dampers under the fan and compressor. Over time, the rubber pads become stiff and the springs sometimes break. This breakdown is eliminated in the following way:


  1. It is necessary to disconnect the refrigerator from the mains and turn it around to access the compressor.
  2. With the help of a wrench or head on 10 unscrew nuts fixing shock absorbers.
  3. Remove the old shock absorbers and install the new ones in their place.
  4. Bolt the nuts in place. Don’t forget to grease the threads with graphite or other greases, so you can unscrew them another time.


Similar manipulations are performed with the fan. All actions must be performed carefully so as not to tear the threaded connections.


Refrigerant overdose


If the refrigerator makes a lot of noise after its charges, the cause of loud sounds in its work can be an overdose of freon. During its circulation, compression, and expansion, pressure is created. If the refrigerant is more than necessary, it grows significantly, and because of this, connections can burst. An excessive increase in pressure is accompanied by an amplified sound, usually a crackling sound.


To eliminate the defect, when the refrigerator makes a loud noise, it is necessary to drain some of the freon, controlling its pressure in the system. Without specialized equipment can not do without, it can be rented. It is enough to connect only a blue manometer to control the pressure in the system. Connection should be made through the Schrader valve.


Clogged piping


If you began to feel a strong hum and vibration, which comes from the radiator or pipes. You may also feel the crackling of the plastic due to the pipes hitting it. This may indicate a clog in the pipeline, resulting from the accumulation of small fractions in one of the places of transition from small to larger diameter. To fix this defect it is necessary to purge the system with nitrogen and then re-fill it with freon. It will require special equipment, which can be rented.


Faults in the elements of the electrical circuit


Sometimes the refrigerator is noisy due to a malfunction in the electrical circuits. In particular, crackling with hissing occurs as a result of bloating of electrolytic capacitors, which, in turn, occurs when the power supply fails. It can also be a trivial element defect. To fix the problem, it is necessary to repair the power board or the board. After that, mandatory diagnostics are required.


Psychological factor


The abnormal noise of the refrigerator is a reason to perform a comprehensive inspection of the device. It should be performed according to the nature of the sound because its source can be many elements. For example, the refrigerator thermostat is defective, due to which it is constantly gaining cold because there is no response signal to the compressor shutdown. In the process, there is a characteristic sound of freon circulation, gradually intensifying. It is important not to manically react to such defects, but to think rationally and act correctly.
