The bottom of the refrigerator is not cooling | Learn the causes and suggested solutions

The refrigerator consists of two main parts, the upper part and the lower part. The upper part is the freezer that freezes food, and the lower part is responsible for the cooling process, but often we face the problem that the lower part of the refrigerator does not cool, without knowing the reasons that This leads to this happening, and therefore we do not know how to act and solve the problem, but in the following article we learn about the reasons for not cooling the bottom, and the appropriate solutions to deal with it. 
Stages of the cooling process
The refrigerator works to cool foods and food products for the longest possible period, and from here the refrigerator acquires its importance, and imposes itself as an indispensable device in any home, but its problems do not end, and revolve around its inability to cool as required, but before addressing the reasons, it is necessary to Knowing the four stages of the cooling process, and we will learn about all the stages that the cooling process goes through step by step below, and those stages are: 
The first stage
The motor, or what is known as the compressor, introduces the coolant in the form of gas to the refrigerator, and the compressor transfers the coolant, at a high temperature, to the external condenser, which takes over the task of transferring it to the next stages. The gas compressor is located at the back of the refrigerator, which is the most energy-consuming part. Electricity in the refrigerator, by the electric motor. 
The second stage
After the gas is transferred to the condenser, which is located at the back of the refrigerator, it works to absorb the high temperature that characterizes it, and expel it outside the refrigerator into outer space, to allow the gas to pass to the next stage, through the network of pipes for the condenser, so it is always recommended to put the refrigerator in A relatively empty place, in addition to having a suitable space between it and the wall or wall in front of it, so as not to damage the refrigerator from the temperature that it expels.
The third stage
The fluid passes through the thermal expansion valve, or the so-called capillary, which is a thin capillary tube, consisting of several coils of copper, through which the fluid that passed through the condenser passes, stripping it of the great pressure on it as it passes through the capillary tubes, until It arrives at the evaporator, which are coils of copper and aluminum tubes, which take on the final task of the cooling process.
Fourth stage
The liquid enters the evaporator located inside the refrigerator, and begins to move to the upper part that is characterized by cold and frost, because the freezer is characterized by greater heat exchange than the lower part of the refrigerator, and then turns into gas by passing through the evaporator, and the fan inside the refrigerator helps the heat exchange
