Situation when the refrigerator compartment stops cooling food, while the freezer compartment continues to operate normally, this is a classic breakdown scenario for equipment Beko. The user can observe that the ice in the freezer is hard, the compressor is humming, but in the upper compartment the temperature rises to room temperature. This causes panic and the risk of spoilage of a large number of products. However, before calling a technician, it is necessary to carry out an initial diagnosis, since in half of the cases the problem lies in simple settings or a temporary failure of the electronics.
Modern models, whether Beko CN 327 or older series, often use a common refrigerant circulation system or separate circuits controlled by a single unit. Temperature imbalance indicates that the cooling capacity of the unit is partially preserved, but the distribution of cold is disrupted. It is important to understand that ignoring the first symptoms can lead to failure of an expensive compressor or a complete replacement of the system No Frost.
In this article we will analyze in detail the mechanical and electronic causes of the malfunction, and consider the specifics of the operation of dual-circuit systems and single-compressor models. You will learn how to decipher the indicator signals and when DIY repairs are safe and when intervention by a certified specialist is required. Don't rush to throw away food - start by checking simple parameters.
⚠️ Attention: If you hear a loud knocking, cracking sound or smell a burning smell, immediately unplug the device. Further operation may lead to a fire or complete destruction of the compressor.
Checking settings and operating modes
Before looking for mechanical failures, make sure that the problem is not caused by an accidental change in control settings. In models with electronic control, such as Beko RCNK, a network failure or power surge could reset the parameters to factory settings or activate special modes. Often, users themselves switch the equipment to the “Vacation” or “Eco” mode, without realizing the consequences for the temperature of the main camera.
Check the display or control panel. If the "Vacation" indicator is on (often indicated by a palm tree or a letter V), then the refrigerator compartment operates in economy mode with a temperature of about +15°C, which is not enough to store perishable foods, but prevents the formation of mold. The freezer works normally. It is also worth checking whether the temperature mode is set to maximum, which in hot weather can lead to cyclic shutdown of the compressor before reaching the set parameters in the freezer, ignoring the upper chamber.
To reset the settings, try disconnecting the device from the power supply for 10-15 minutes. This will allow the control board to reboot and clear any possible software errors. After turning on, set the standard values: usually this is -18°C for the freezer compartment and +4°C for the refrigerator compartment.
Faults in the defrosting system (No Frost)
The most common technical reason for the situation when the freezer freezes but the refrigerator does not is a failure in the automatic defrosting system No Frost. In a working unit, the evaporator, located behind the rear wall, periodically heats up to melt frozen frost. If this process is disrupted, the evaporator becomes overgrown with an ice “coat”, which blocks the channels for supplying cold air to the fridge compartment. As a result, the fan circulates air inside the freezer, but no cold enters the upper compartment.
The key elements of this system are a defrost heating element, a defrost sensor and a timer (or electronic control module). If the heating element burns out, the ice does not melt. If the sensor is faulty, it does not give a command to turn on the heating or, conversely, does not turn it off in time. In models Beko often it is the defrost sensor that fails, which stops correctly reading the evaporator temperature.
For diagnostics it is necessary to defrost the refrigerator completely (at least 24 hours with the doors open). If after switching on the unit worked normally, but after 5-7 days the problem recurred, this is a guaranteed sign of a malfunction of the defrosting system components. Ice will block the air channels again.
How to check the defrost heating element with a multimeter?
To check, you need to remove the back panel in the freezer, get to the heating element and “ring” its contacts. The resistance of a working heating element is usually from 200 to 400 Ohms. If the device shows a break (one or zero depending on the tester model), the element requires replacement. Remember that replacement requires disassembling the case and having skills in working with electrical equipment.">
Problems with the fan and air circulation
In systems No Frost cold air is forced by a fan from the freezer into the refrigerator through special air ducts. If the fan stops, the cold remains at the bottom, while in the top the compartment becomes warm. This is the second most common reason after problems with defrosting.
The reasons for the fan stopping can be different. Mechanical blocking of the blades with ice is a common occurrence of a faulty defrosting system. It is also possible that the fan motor bearings wear out, which is accompanied by a characteristic hum, creaking or complete absence of noise from the motor. Beko a break occurs. wiring going to the motor due to constant vibration or kinks during assembly.
To check the operation of the fan, open the door of the refrigerator compartment. In most models, when the door is open, the fan should stop (the limit switch is activated). Press this switch with your finger (simulating a closed door) and listen. works.
⚠️ Warning: Never try to check the operation of the fan or other electrical components without unplugging the refrigerator. The risk of electric shock from contact with wet parts inside the chamber is extremely high.
Refrigerant leaks and problems with the compressor
If the defrost system and fan are working, but the cold does not flow into the refrigeration chamber, the problem may lie in a freon leak. In two-chamber refrigerators with one compressor, the refrigerant first passes through the freezer chamber, releasing some of the cold there, and then enters the refrigeration chamber circuit. If there is a small leak in the freon pressure, it may only be enough to freeze in the first circuit (freezer), and the gas simply does not reach the second circuit (refrigerator) or does not have time to cool. evaporator.
Leakage symptoms often appear gradually. At first, the refrigerator starts to work longer, then the compressor starts to turn on less often or, conversely, works without stopping, trying to increase the temperature. On modern models with linear compressors, areas with different temperatures may appear, a leakage can lead to sensor errors that block the operation of the unit.
Another reason could be capillary tube cloggedOil breakdown products or moisture entering the system form a plug that prevents the circulation of freon. The pressure at the inlet of the compressor drops, and the cooling capacity decreases sharply. It is impossible to eliminate the leak or blockage on your own without special equipment (vacuum pump, pressure gauges, freon supply). data-i="87">clogged capillary tube
Failure of the damper and thermostat
In some models Beko, especially with technology Dual Cooling or an improved air distribution system, the cold supply is regulated by a special damper (throttle valve). This is a mechanical or electromagnetic element that opens and closes the channel between the freezer and the refrigerator. If the damper is stuck in the closed position, cold air cannot physically enter the upper chamber.
It is also worth considering the possibility of a malfunction of the thermostat (thermostat). that the freezer is not cold enough, it will not give the command to switch modes or will continue to run the compressor only to freeze, ignoring the needs of the refrigerator compartment. However, more often, if the thermostat breaks down, the refrigerator either does not turn on at all or freezes all compartments excessively.
Diagnostics of the damper requires partial disassembly of the internal panel of the refrigerator compartment. It is necessary to visually inspect the mechanism: is there any ice interfering with the movement, and is the control rod intact? In electronic models, when the damper motor breaks down, the corresponding error code often lights up on the display.
Error codes and electronics diagnostics
Modern refrigerators Beko are equipped with a self-diagnosis system. If a malfunction occurs, indicators or alphanumeric codes may light up on the display. Understanding these signals greatly simplifies troubleshooting. For example, a flashing Alarm light or a red temperature light often indicates a long period of high temperature, which confirms our diagnosis.
Common error codes can indicate:
- 🔴 Sensor error evaporator: Most often indicates a problem in the No Frost system (open or shorted sensor).
- 🔵 Damper error: Failure of the air damper motor or its mechanical jamming.
- 🟡 Error communications: Failure of communication between the control board and the display or inverter module.
- 🟢 Inverter error: Problems with starting the compressor or its operation at low speeds.
To accurately decipher the codes of a specific model Beko (for example, CNE 460 or RCNE 520) you must refer to the technical documentation or service manual, since the blinking combinations may differ. The electronic control module is the “brain” of the refrigerator. Voltage surges could damage its elements, causing it to incorrectly control the heating elements or fan. Board repair requires professional soldering and circuit design.

⚠️ Attention: Design details and location of components in different series of refrigerators Beko may vary. Always check the instructions for your specific model before starting disassembly.
Recommendations for prevention and operation
To extend the life of the refrigerator and avoid situations where it stops freezing, it is important to follow the operating rules. Regular defrosting at least once a year (even for No Frost systems) helps prevent the formation of dense ice plugs in hard-to-reach places and reduces the load on the defrosting system.
Keep the condenser grill at the back of the refrigerator clean. Dust and pet hair act as a heat insulator, causing wear and tear on the compressor, which can lead to overheating and failure. Also, do not overload the chamber with products by blocking the ventilation holes, as this interferes with air circulation.
☑️ Primary diagnostic checklist
If you notice that the rubber door seal has lost its elasticity or does not fit tightly, replace it. The constant influx of warm, humid air leads to increased formation of ice on the evaporator, which ultimately blocks the system. No Frost.
Frequently asked questions (FAQ)
Can I use a Beko refrigerator if the refrigerator compartment does not work, but the freezer does?
Use the unit in This mode is only possible temporarily (1-2 days) while you wait for the technician or carry out defrosting. Long-term operation with a blocked evaporator or a freon leak will lead to overload and combustion of the compressor, which will make repairs economically unfeasible.
How long does it take to defrost the refrigerator to remove the ice plug?
It takes at least 24 hours for the ice in the hidden channels and on the evaporator to completely melt. Defrosting for 2-3 hours is often insufficient, since the ice deep in the air ducts remains solid. It is recommended to leave the doors open for a day.
Why did the refrigerator start working after defrosting, but after a week it stopped again?
This is a classic sign of a malfunction of one of the components of the automatic defrosting system (heating element, sensor or timer). Ice builds up again because the ice removal mechanism does not work. Diagnostics and replacement of the faulty part is required.
Is it possible to replace freon in a Beko refrigerator yourself?
No. Replacing the refrigerant requires evacuation of the system, precise dosage of gas and special equipment. In addition, modern types of freons require compliance with environmental standards. An independent attempt to refill will only damage the compressor.
What does it mean if the compressor is hot, but the refrigerator does not freeze?
A hot compressor in the absence of cold usually indicates that it is running idle due to a freon leak or a clogged system. The gas circulates, but does not participate in heat exchange effectively. Urgent repairs are needed.
