Why is condensation collecting on the back of the refrigerator?

Good evening. You did not specify the model of the refrigerator, and this is very important information for quality assistance. But I will try to answer you.

The cause of condensation is always the same - the temperature difference when warm air meets cold air and a dew point is formed. In the refrigerator, dew forms on the back wall, because there is an evaporator inside it, the function of which is to draw in warm air from the chamber and cool it.

Of course, condensation is not always the norm. But there are exceptions, for example, some modern models of refrigeration equipment, have a system of automatic self-freezing, which is why, periodically, condensation forms on the wall.

If you do not have such a function, I will assume several other possible reasons. As we have already found out, a dew point always forms at the place of collision of cold air with warm air. In the refrigerator, the reason may be:

1. The fact that you or your household put on the shelves unheated foods, especially often because of soups, stewed fruit, especially if they are without a lid and still soar. The solution is to defrost the refrigerator, dry it thoroughly from moisture, and continue to not place hot foods on the shelves.

2. In depressurization of the refrigerator (see photo). The seal on the door is responsible for the tightness, this is such an accordion-gum attached along its edges. If she leaves, you will notice it on a loose fitting door, air will flow into the refrigerator from the room and dew will drop out. The sealant usually deteriorates from old age, mechanical stress, or the expansion of frozen moisture.The solution is to replace the seal, if this is not possible in the near future, an attempt to temporarily repair it (drying and repairing cracks).

3. It is hot in the room or the refrigerator is leaning against the heating system having a high temperature mode. Because of this, the compressor of the device has to undergo serious stresses in order to maintain the established microclimate, and it can even fail. The solution is to move the refrigerator to a free wall that does not have heating radiators and other systems, because of which it heats up.

4. Food contains a lot of moisture. Which, after falling from a warm environment to a cold one, begins to freeze and settle with dew. The solution is that any refrigerator has a special freshness zone. Usually this is the bottom of the refrigerator, where the temperature is zero. It has compartments or plastic boxes designed to store fruit, vegetables and what is called chilled food, food that you thawed, but for some reason you still haven’t cooked. In order to prevent dew from falling on the wall, store vegetables, fruits and chilled in these compartments or in airtight containers, and always close soups, milk and other liquids with a tight lid for storage.

5. The drainage system of the fluid drainage is clogged (see photo). Please note that at the bottom of the camera is a hole that comes out of the back of the refrigerator with a tube. The solution is to rinse it or clean it very carefully. Typically, this problem occurs with refrigerators, which have a defrost know-frost system.

6. Very often open the door of the refrigerator. There is such a joke that social networks are like a refrigerator, like you know that nothing new appeared there, but you constantly look there. Accordingly, warm air from the room, in large quantities, enters the chamber and cools, condensation forms. The solution is to climb into the refrigerator less often. For example, I have just such a problem at home because of children.

7. Too low temperature is set on the regulator in the chamber. Solution - Take a look at the summary of your refrigerator. If you have lost documents for it, look on the Internet, usually the operating instructions can be easily found on the network. I would now advise you a lot of ways in setting the mode yourself, but it is best to do it according to the manufacturer's recommendations, they are the most optimal.

8. Do not defrost the refrigerator. Usually this is a disease of refrigerators without know-how, single-chamber. You know, when you do not defrost the model for a long time, the ice begins to stick out from the freezer compartment and, accordingly, the temperature regime inside the device changes. Solution - defrost the refrigerator according to the manufacturer's recommendations and a little secret that is rarely voiced by the manufacturer - do not freeze more than 4 kg at a time. It is better to do a gradual freezing, ideally, if it is chilled, so frost will not grow in huge quantities and it will be easier for the refrigerator to cope.

And finally, disappointing reasons because of which, you may have to apply for repairs.

1. As you know, in such a device there can be 1 camera with 2 compartments or 2 cameras - a refrigerator and a freezer. There are exceptions - 1-chamber hotel-type refrigerators without a freezer, but now we are not talking about these models. In a refrigerator with 1 chamber, with a freezer, often a very weak evaporation system. If for some reason it does not work to the full extent and the refrigerant does not have a sufficient temperature, droplets are formed that begin to flow down the walls. Failure or weakness of the evaporator, the problem is very serious and you cannot fix it yourself, contact the service if the warranty is valid or the repairman for refrigeration equipment.

2. The same applies if there is a problem with the violation of the tightness of the circuit, breakdowns in the housing, freon and so on.

Try to check the above reasons, if it doesn’t help, call the wizard or in the comments to the question, give us details - the model of the refrigerator, a photo of it from the inside.
