A new refrigerator of the latest brand, which has a low degree of noise, began to buzz loudly, and this definitely creates discomfort. The question immediately arises, why does it make noise - is it absolutely new and does it still have a guarantee? How to be in such a situation? After all, only a faulty or disconnected refrigerator does not make sounds.
Features of the location of the refrigerator
It is possible that the refrigerator makes a lot of noise during operation, due to the wrong location in the kitchen. First you need to find out what is the reason for the noise. The main source of noise from the refrigerator is the compressor. It builds up a cold temperature, and it is he who makes a loud noise, buzzes and rattles. If it is equipped with two compressors, then the noise level is doubled, since each of the compressors will operate at different times in a relaxed manner.
In the case of a working refrigeration unit, the compressor noise level is quite bearable, here you just need to come to terms with it. If the refrigerator not only makes a lot of noise, but also emits irregular rattling sounds, then the problem lies in another reason, which is quite solvable. You will first need to check if your refrigerator is close to a wall or furniture. In addition, usually the vibration of the device can occur due to nearby objects. Be sure to make sure that refrigerator is installed correctly... If necessary, adjust the legs.
As for the camera, the inside of the camera needs to be cleaned up. If the refrigerator starts humming loudly and the sound of rattling and clinking dishes is observed, then the explanation lies in the products that adhere tightly to the walls. In particular, we are talking about glass jars and dishes with metal lids.
It is worth noting that before buying a new refrigeration unit, it is recommended to check it before turning it on so that the compressor tubes do not come into contact. Otherwise, unnecessary noise will be generated.
Why the refrigerator began to buzz loudly: the causes of the malfunction
- Defective shock absorbers. If earlier the new unit worked well, and then it began to make noise, you need to look at the compressor shock absorbers. If they are not firmly fixed, secondary noise will occur. Therefore, there is nothing to be surprised that the unit began to rattle and "bounce". Replace the defective compressor shock absorbers with a new one and then the problem will be solved.
- Refrigerant. A household appliance using refrigerant may start to make a loud noise due to the gas circulating in the frenzied tubes. There is nothing like that, this is normal. We'll have to get used to the humming of the refrigerator. Read also: How to fill the refrigerator with freon at home.
- No Frost. Chambers of units equipped with No Frost may experience noise generated by the rotation of the built-in fan. If the device suddenly began to hum a lot during operation, then this is due to ice that is frozen near the blades.Here, the salvation will be a complete defrosting of the refrigerator, which will take at least 10 hours.
The new refrigerator makes noise
According to GOST standards, the permissible noise level of the refrigerator is data up to 55 dB and this is the average sound. However, if you look at the manufacturer's attached instructions, most of the latest batches have it about 40 dB.
Note that when choosing a technique, you need to pay attention to the label on the front of the device. You will see the power consumption class, the volumes of each chamber and the decibel reading. If you want the refrigerator compartment to work almost silently, analyze the models and get the one that has the lowest noise reading.
And if, when choosing a quiet unit, there is still a strong hum? We do the following:
- check the removal of the shipping bolts. They fix the springs where the compressor is mounted. If you do not remove the bolts, the refrigerator will rattle and make a loud noise.
- let the refrigerator stand a little. Let it freeze a little - it will take a week for the device to return to normal functioning.
- third - check if the device is installed correctly. Is there any contact with objects or nearby furniture? For normal operation, it is required to leave a space of about 5 cm to the wall.
- pay attention to the loading of the refrigerator. By the way, this applies to new and old refrigeration units. It is possible that pots or cans are in contact with each other inside - this creates a ringing. Here you just need to properly distribute the contents on the shelves.
- Have you noticed that the hum of the refrigerator is only at the beginning of the compressor operation? This is normal! At the beginning of the start, the motor needs a large starting current, which is why you hear the short growl of the refrigerator.
