Should the back of the refrigerator be hot?

Stages of diagnostics and repair of equipment

Fixing problems on your own will not be easy. Cleaning the drainage system, diagnosing the state of the compressor, measuring the level of freon is possible only with the use of professional equipment. Particular attention should be paid to situations where moisture accumulates in the freezer. This may indicate a valve breakdown or a general decrease in the efficiency of the equipment.

  • Checking for possible minor faults. The master will check whether the seal fits snugly to the seat, if there are any gaps.
  • Detection of technical reasons why condensate may collect inside the refrigerator.
  • Inspection of the condition of the drainage system. Usually in such situations, the drainage system is purged to ensure its effectiveness.
  • Diagnostics of functional equipment. Problems may arise due to low freon levels, loss of oil properties.
  • Repair of the refrigerator in accordance with the problems found. The cost depends on the specifics of the detected problems.

Serious and expensive to fix, condensation rarely shows. It is worth urgently calling the master if moisture accumulates outside. Also, in the event of the appearance of strong condensate, you should carefully consider the issue of diagnostics. This may be a sign of violations in the freon circulation system. The refrigerant does not pass through the entire system and ineffectively distributes cold. Over time, a lot of frost and ice can freeze, which will lead to a complete loss of efficiency of the equipment.

hot wall! Sound the alarm?

The problem in which the wall of the refrigerator heats up is one of the common. From a technical point of view, a refrigerator is a unit whose work is aimed at pumping thermal energy, according to the principle of a heat pump. If heat is felt during tactile contact with the wall of the unit, then there is still no reason to panic, since it is in the wall that the manufacturer embeds the capacitor.

When heating and moving the necessary heat flow for the freezer and chamber, the surface can become very hot. Such a process for a number of models is a common operating point. Therefore, consumers should take this fact into account when installing the unit. Space should be left between the back wall of the refrigerator, and the device itself should not stand close to furniture.

Wrong location

The reason for the strong heating of the side and back walls of the refrigerator may be its incorrect location. According to technical standards, the distance from them to the walls of the room and furniture should be at least 10 cm. If the appliance is built-in, then the top shelf should be more than 20 cm. Although some models may have different requirements.

If the gaps are smaller, there will be problems with air circulation. It will stagnate, so the heat exchangers will not be able to quickly release heat. Freon will heat up, transferring thermal energy to the walls.

Another side effect of improper installation of the refrigerator is the rapid wear of the compressor. To maintain a normal temperature in the chambers, it will start working at a higher speed, turning on more often. This will lead to a decrease in its resource and failure.

Forgot to turn off or set up?

In older models and inexpensive refrigerators, the superfreeze function is controlled manually. It doesn‘t turn off automatically. If ice suddenly begins to form and accumulate on the walls of the freezer, check if SuperFrost is turned off.

The most common reason why the refrigerator is covered with ice and snow inside is the wrong temperature. If you set the chamber temperature to 5°C, the evaporator will always be colder.

If the temperature is too low, the evaporator can cool the back wall below 0 degrees. because of this, the back wall will freeze over. The solution to the problem is simple. defrost the refrigerator and set the temperature 1 degree higher. if this does not help, repeat the procedure.

True or False: It isn’t safe to put hot food directly into the refrigerator

What to do with excessive heating of the walls

Normally, the compressor runs for about 20 minutes, and then turns off for the same period of time. Accordingly, during these periods, the walls of the refrigerator heat up and cool down. If the surfaces are equally warm all the time or their temperature sometimes becomes too high, this is a reason to be wary.

Situations that do not require intervention

In some cases, the intensive operation of the compressor is a normal reaction of the device to your recent activities:

To quickly reduce the temperature to operating temperature, the motor will turn on more often, and the walls will heat up more.

Problems that you can solve yourself

When figuring out why the side walls of the refrigerator are heating up, first of all, make sure that the rules for its operation are not violated.

  • Super Freeze/Super Cool permanently on. They only need to be installed for a short time after loading the freezer or refrigerator compartment.
  • The refrigerator is installed too close to a heat source: a radiator or a stove. In summer, overheating can also cause prolonged exposure to direct sunlight.
  • Hot food was placed in one of the cells. You can’t do this: this both overloads the compressor and provokes the appearance of ice. Read our article on how to properly store food in the refrigerator.
  • The door is not tightly closed, and warm air constantly enters the compartment.
  • A thick layer of frost has accumulated in the freezer, and the appliance needs to be defrosted.
  • Normal cooling is hindered by a thick layer of dirt and dust accumulated on the rear grille. Remove it with a vacuum cleaner or a soft bristle brush.

Proper placement of products in a weeping refrigerator

If you have a refrigerator with a drip system (the so-called crying), look at how food is placed in it. In such models there is no forced airflow, as in No Frost. Therefore, you can not force the back of the camera.

If the products are located close to it, cold air will not enter the rest of the chamber. Get a temperature difference. The temperature sensor will receive incorrect data and give the command to turn on the compressor more often, or increase its speed.

How does a refrigerator work and what is a heat pump

People who are at least a little familiar with technology know that a refrigerator, at its core, is a device called a heat pump. That is, special equipment that pumps the thermal energy of a substance from one place to another. In the case of a refrigerator, such pumping occurs in the direction from the refrigerator (freezer) chamber to the outside. That is, a lower temperature inside is achieved due to the fact that the temperature somewhere outside becomes high.

Why does the compressor heat up

Compressor overheating can be caused by the following reasons:

  • Cameras overloaded with products. If overfilled, the circulation of refrigerant and air is disturbed. As a result, the compressor overheats.
  • Placement of uncooled food on the shelves of the refrigerator. In order to cool the air inside the unit to the optimum temperature under such conditions, the motor will have to work much longer. Its temperature will rise significantly.
  • The refrigerator door remains open for a long time. Modern models have special indicators that give the appropriate signal in a timely manner. The main thing is to hear him and immediately close the door. If you leave the refrigerator wide open every day, then you can not count on the long and efficient operation of the compressor.
  • Defrost not done properly. It would be more accurate to say out of time. A thick layer of snow on the walls of the chambers is one of the most common causes of motor overheating.
  • The dishes in the refrigerator are placed incorrectly. Containers made of glass, metal or plastic are not recommended to be leaned against the back wall. After all, the compressor at the same time begins to cool the dishes themselves.
  • Faulty heat exchanger.
  • Refrigerant leak. If the pipes of the cooling system are deformed and damaged, freon begins to be released outside.
  • Temperature sensor failure. When a certain temperature is reached, the compressor does not turn off. It works non-stop and, as a result, overheats.
  • Incorrect unit position. The compressor will certainly overheat if the refrigerator is near heating appliances. If it is pushed too close to the wall, ventilation will be disturbed, which will also lead to an increase in temperature.
  • Depreciation of the electric motor after the allotted time. The material from which the elements of the system are made gradually wears out. Damaged parts must be replaced with new ones.

Important! Even the highest quality equipment after 10-15 years of operation needs to be repaired.
