The situation when the Atlant refrigerator starts to freeze too much is familiar to many owners of this equipment. Products in the freezer are covered with a thick crust of ice, and vegetables in the refrigerator compartment are frozen or covered with frost. This is not just an inconvenience, but also a direct risk of spoilage of supplies, as well as a signal that the temperature control system is not working correctly.
The main reason lies in the imbalance between the operation of the compressor and the heat removal system. Thermoregulator it may give incorrect readings, or the ventilation ducts are clogged, which leads to uneven distribution of cold. Users often notice that the problem grows gradually: first, ice appears on the back wall, and then the contents of the shelves begin to suffer.
Before calling a technician, you need to conduct independent diagnostics. In most cases, Atlant refrigerators allow you to adjust the temperature manually or remove simple mechanical obstacles to air circulation. Ignoring the problem can lead to increased energy consumption and accelerated wear of the compressor.
Diagnostics of the causes of excessive cooling
The first step should always be a thorough check of the operating conditions. Owners often forget that densely loading shelves blocks the escape of cold air. If food is placed close to the back wall, it blocks access to evaporatorwhich causes the temperature sensor to “think” the chamber is warmer than it actually is and causes the compressor to run non-stop.
⚠️ Warning: Never place hot or warm food inside cameras. This causes a sharp jump in humidity and forces the unit to work at its limit, which often leads to the formation of a “fur coat” and erroneous sensor readings.
It is also worth checking the condition sealing rubber on the door. If it does not fit tightly, warm air from the room constantly enters. The cooling system reacts to this by increasing its operating intensity, trying to compensate for the heat gain. As a result, excess cold forms inside, and condensation forms on the walls, which immediately freezes.
Particular attention should be paid to the model of your device. In single-compressor models with a No Frost or drip defrosting system, the reasons may differ. For example, in models with manual defrosting, excess cold often indicates that the owner simply forgot to defrost the unit in time, and the ice crust began to act as an insulator for the sensor.
Setting the thermostat and control panel
The most obvious, but often ignored, way to solve the problem is to adjust the settings. In older Atlant models, this is done by a mechanical mechanism, located inside the chamber or outside on the body. Its scale usually has divisions from 1 to 7 (or from Min to Max). If the regulator is set to the maximum value, the compressor will operate almost continuously. thermostat, located inside the camera or outside on the housing. Its scale usually has divisions from 1 to 7 (or from Min to Max). If the regulator is set to the maximum value, the compressor will work almost continuously.
For mechanical regulators, the optimal position is considered the middle of the scale, usually division 3 or 4. Turn the handle toward lower values should be done smoothly, with an interval of several hours, so that the system has time to stabilize. An abrupt change of mode can lead to false triggering of the protective mechanisms.
In modern electronically controlled models, the settings are made through the display on the door. It is important here not to confuse the temperature in the refrigerator and freezer compartments. Standard values at which products are stored safely, but do not freeze, are:
- 🌡️ +3...+5°C for the main compartment;
- ❄️ -18...-20°C for the freezer;
- 🥩 0...+2°C for the zero zone (if any).
It is worth noting that in the summer, when the temperature in the kitchen is high, slightly more intense operation of the compressor may be required, but this should not lead to freezing of food in the refrigerator compartment. If even at the minimum settings the cold does not decrease, the problem lies deeper.
Problems with the defrosting system and sensors
If a simple setting does not help, one of the elements of the automatic defrosting system has probably failed. In Atlant refrigerators, the evaporator heating element, defrost timer and defrost sensor are responsible for heat removal and moisture removal. If the heating element is burnt out or the timer is “stuck” in cooling mode, ice builds up on the evaporator. No Frost The evaporator heating element, defrost timer and defrost sensor are responsible for heat removal and moisture removal. If the heating element is burnt out or the timer is stuck in cooling mode, ice builds up on the evaporator.
This ice lump blocks the air supply channels. As a result, cold air does not circulate normally, and the temperature sensor, located far from the cold source, does not see changes and does not give a command to stop the compressor. Visually, this manifests itself as severe cold at the bottom or at the back wall, despite the fact that the upper shelves may be warmer than normal.
⚠️ Attention: Replacing the heating element or timer yourself requires disassembling the rear panel of the freezer. If you do not have the skills to work with electrical circuits, it is better to entrust this procedure to a specialist, as there is a risk of damaging fragile plastic or wiring.
In models with a drip system ("crying evaporator"), it often fails itself thermostat. It may "stick" in the "On" position, constantly supplying voltage to the compressor. You can check it by disconnecting the refrigerator from the network, removing the regulator and ringing its contacts with a tester at different temperatures, but this will require removing the device from the case.
How to check a temperature sensor with a multimeter?
To check the sensor (thermistor), you need to know its resistance at a certain temperature. Typically at room temperature (+25°C) the resistance is several kOhms. When cooling (for example, if you hold the sensor in your hand with ice), the resistance should change. If the readings do not change or are equal to zero/infinity, the sensor is faulty.
The influence of refrigerant and compressor
Sometimes the cause of excess cold lies in the disruption of refrigerant circulation. If a micro-clog occurs in the system or a freon leak occurs (which is paradoxical, but possible), the compressor may not work properly. However, most often, when there is a leak, the cold, on the contrary, disappears. Excessive cold with a faulty compressor is a rare case associated with a malfunction of the motor or start relay.
If compressor it hums continuously, without turning off for hours, and at the same time there is “polar cold” inside the refrigerator, this is a sure sign that the cooling cycle is not completed. The system does not receive a signal that the target temperature has been reached. This may be due to either a freon leak (in some circuits) or problems in the electronic control module.
| Symptom | Probable cause | Solution |
|---|---|---|
| Ice only on the rear wall | Faulty defrost sensor or heating element | Replacement of No Frost system elements |
| Refrigerator does not turn off | Thermostat stuck | Replacement thermostat |
| Food freezes at the door | Loose seal seal | Replacing or restoring the rubber band |
| Noisy operation and cold | Fault fan | Lubricating or replacing the fan |
It is important to understand that intervention in the circulation circuit refrigerant requires special equipment. If you suspect a leak or clogged capillary tube, independent repair is impossible without a vacuum pump and a pressure gauge station.
Mechanical obstacles and equipment care
Even a working Atlant refrigerator will freeze too much if the rules of its operation are violated. Often, users do not notice that the egg cup or vegetable container is not installed correctly and is blocking the air flow. As a result, cold air blows directly onto the food lying nearby, freezing it.
Regular defrosting is a mandatory procedure. Even models with Full No Frost require prevention at least once a year. Dust accumulation on the condenser (the grill at the back of the refrigerator) also impairs heat transfer. The unit is forced to work longer and more intensely in order to release heat, which can lead to malfunctions in temperature conditions.
☑️ Check-up of the refrigerator
Cleaning the drainage hole is another important point. If the water does not drain, it freezes in the channel, creating an ice plug. This disrupts the operation of the moisture removal system and can indirectly affect the temperature background in the lower part of the refrigeration chamber.
When you need to call a specialist
There are a number of signs in which independent attempts to reduce the cold can lead to equipment breakdown. If you have gone through all the settings, checked the seals and defrosted, but the situation has not changed, professional diagnostics are required. The symptoms are especially alarming when the refrigerator operates cyclically, but the cycles are becoming longer.
A master is needed if:
- 🔧 The compressor works without breaks for more than 12 hours;
- 💧 There is a lot of water inside the refrigerator or, conversely, everything is dry and frozen;
- 🔌 The relay clicks are heard, but the compressor does not start or runs jerkily;
- 👃 A specific smell of burnt wiring or chemicals has appeared.
⚠️ Attention: If your refrigerator is under warranty, any independent opening of the seals on the compressor or control unit will result in to loss of warranty obligations. In such cases, contact only an authorized service.
A specialist will be able to accurately determine whether the problem lies in electronic modulethat is sending incorrect commands, or whether expensive components such as a compressor need to be replaced. Do-it-yourself repairs in such cases are often more expensive due to the risk of aggravating the malfunction.
Why did the refrigerator start to freeze even more after defrosting?
After defrosting, the system starts in maximum power mode to quickly gain temperature. This is a normal process. However, if the super freeze mode is not turned off automatically or manually, the cold will increase. Check if the quick freeze indicator is on.
Is it possible to seal the hole in the seal with tape?
Temporarily - yes, but this is not a solution to the problem. The tape breaks the elasticity of the elastic band and will begin to let air through even more over time. It is better to order a new sealing rubber for your Atlant model, since this is a consumable item.
Does the location of the refrigerator affect the strength of the cold?
Yes, if the refrigerator is too close to the wall or heating appliances, the ventilation of the condenser is disrupted. The unit overheats and may not operate correctly, including producing temperature errors. Leave a gap of at least 5-10 cm from the walls.
What to do if bottled water is frozen and the thermostat is at minimum?
If the regulator is at minimum (the warmest mode) and the water freezes, it means the thermostat is faulty and does not open the circuit. It needs to be replaced. You cannot operate the equipment in this mode for a long time - the compressor will burn out.
How often do you need to change the thermostat in Atlanta?
The service life of the thermostat is not strictly regulated, but usually it is 5-7 years of active use. Frequent power surges in the network can shorten this period. If you notice that the temperature “floats”, check this unit first.
