. We bought a refrigerator, turned it on, 10 hours later, when it's working. Or so it should be the first days? Why? Marat.

Just bought a refrigerator can make noise for several reasons considered below. In this case, you can eliminate troubles yourself.

Incorrect installation of the unit

This is the wrong vertical and horizontal position of the refrigerator. As a result, due to distortion, the compressor touches the metal parts of other parts of the unit. It also happens that one of the support legs just hangs in the air.

To eliminate this trouble, measure the position of the refrigerator through a building level or apply a plumb. It can be made from a fishing line or thick yarn, to which a small weight of 20-50 g is suspended. When everything is OK, do not forget to check the legs: the floor can be uneven.

A check can even be carried out by an unskilled person in an electrician

Incorrect operation of the compressor

Here we mean the lack of air for this refrigerator unit. A similar problem is typical for small apartments, as well as housing, heavily furniture. As a result, the compressor does not cool well, which leads to an excessive load, due to which the device begins to create a vibration, transferring it to other parts of the unit, and an additional knock give overheating valves. It is also possible to form an ice layer on the tube connected to the compressor. As a result, she begins to touch the metal parts and make noise.

Knock can make a tube covered with ice

To solve the problem, it is sometimes enough to simply remove the unit away from the wall (a minimum distance of 20 cm) and move the furniture next to it.

Compressor mounting

If the above methods do not work, then it makes sense to check the reliability of this element. In early models, it is suspended on the springs. If their fastening loosens, then the knot will move to the side and will graze the neighboring parts and the body of the unit itself. For example, a pipeline is simply an ideal resonator, which creates a sufficiently loud noise. Also inspect the rubber gaskets under the compressor supports: they may have jumped out during the transportation.

But there is also the opposite situation. The fact is that in some models there are compressor transport bolts (most often these are 12-12 mm diameter hardware) that protect the unit from splashing during transport. Usually in stores they are cleaned. If this is not done, the compressor operates in a non-free, as it were, stressed state and transmits vibration to the refrigerator body. It is enough to unscrew these bolts to make the unit work normal.

Some unlikely variants can also cause extraneous sounds.
