Any refrigerator can make noise and buzz during operation, regardless of the period of operation. The question is how much noise is above normal. Some users complain of a whistle in the refrigerator. The reasons for its origin may be different. Pay attention to exactly when the whistle is heard: when you open the door or at another time.
What should I do if the sounds during the operation of the equipment interfere with sleep?
Why the refrigerator whistles and makes noise
All household appliances are humming and noisy at work. But if we are ready to put up with the temporary work of a vacuum cleaner or a blender, then it is impossible to live with the strong constant noise of the refrigerator.
You can find out how much the equipment is noisy when working, even in the store - it is not necessary to open the instructions. There is a sticker on the case where the energy saving class is indicated, as well as the noise level in dB. At home, the sound of the equipment may differ from the declared ones, since testing is carried out in the factory. But if the refrigerator whistles during operation, then a malfunction has occurred.
The main reason for whistling is in the refrigerator fan (LG or another brand). The installed No Frost system provides for a fan that drives cold air.
Sometimes the fan blades are covered with a layer of ice, which causes extraneous sounds during operation. Then you need to defrost the equipment. But if after a defrost you hear a whistle, grease the fan with spindle oil. This is engine oil that does not freeze at low temperatures.
Another cause of whistling is the circulation of refrigerant throughout the system. This is generally considered a normal symptom. You can hear gurgling, gurgling and other "incomprehensible" sounds. The environmentally friendly refrigerant in the system moves faster, so you can hear the whistle.
What other details cause extraneous sounds in the refrigerator?
Motor compressor
The compressor periodically turns on and off. You can add to the sounds of a running motor:
- rattle of dishes, if it is closely located to each other;
- vibration of the cabinet with furniture or battery nearby.
Therefore, it is important to even install the equipment, maintaining a distance of at least 5 cm from the wall and furniture.
The noise of the motor will be heard more often if the refrigerator is two-compressor, since each compressor operates separately.
Start relay
When the relay starts and stops, clicks are emitted. This is the normal operation of the device, so do not worry.
No Frost Cooling System
Despite all the advantages, the “Without Hoarfrost” system works louder than the usual drip installation. The reason for this is two fans, in the refrigerator and freezer compartment. Add to this the noise of the refrigerant through the pipes.
Of course, not everything is so simple. The noise level depends on the manufacturer. Even a large refrigerator equipped with the latest technology can be quieter than a small and compact one if the manufacturer has thought through all the details and developed high-quality sound insulation.

Refrigerator installation rules
To avoid extraneous sounds that will cause irritation over time, follow simple rules:
- Do not put the refrigerator close to other furniture, leave a gap of 5-10 cm.
- Do not install near heaters or gas stoves.
- Connect only to a grounded outlet. It is advisable to install a mains fuse.
- Make sure that the refrigerator is installed in level, with a slight deviation back - otherwise the door will open.
- Leave space at the rear of the appliance for proper ventilation.
Be attentive to the operation of the refrigerator. If for a long time you are bored with loud noise, it is better to call the wizard. When the new equipment is noisy, you can go to the store where the purchase was made.
