The situation when the refrigerator Beko continues to work, but stops cooling food in the upper compartment, is one of the most common and alarming for owners of household appliances. Unlike a complete compressor failure, when the unit is silent, here the motor can hum, creating the illusion of normal operation until the food supplies in the freezer or refrigerator begin to spoil. Most often, the problem lies not in a breakdown of the compressor itself, but in a disruption in the circulation of the refrigerant or a malfunction in the control system.
Modern models No Frost are more complex than old two-chamber systems with drip defrosting, so the lack of cold from above often indicates problems with air removal or evaporator operation. It is important not to panic and not to try to pick the internal components with sharp objects, as this can lead to a freon leak. Primary diagnosis requires a calm analysis of symptoms and a consistent check of simple causes before calling a technician.
Owners often ignore the first signs of a malfunction, such as the rare start of the compressor or the appearance of condensation on the back wall, which ultimately results in expensive repairs. Understanding how your model works Beko will help you quickly identify the root of the problem. Below we will analyze in detail the algorithm of actions that will allow you to determine whether you can handle it yourself or whether you will need to replace expensive components.
Primary diagnostics and checking settings
Before disassembling the unit or looking for spare parts, it is necessary to eliminate the human factor and banal operating errors. It often happens that the refrigerator Beko does not freeze the upper compartment due to accidentally lost settings of the thermostat or operating mode. In models with electronic control, children or pets can press a combination of buttons that activates the "Vacation" mode or forcibly increases the temperature.
Check the control panel: if the indicator Eco Mode or the snowflake icon with a strikethrough is on, the system may be operating in an energy-saving mode, where the temperature in the refrigerator compartment is maintained at +14...+15°C, which is not enough for storing perishable products. It is also worth making sure that the door closes tightly and that the seal does not have cracks through which warm air enters, interfering with the operation of the sensors.
⚠️ Attention: If you notice that the rubber door seal is deformed or has tears, do not try to fix it with tape or glue. A loose door seal causes the compressor to work hard, trying to compensate for heat loss, which ultimately leads to its combustion.
Pay special attention to the location of the products. If you tightly pack the shelves at the very exit of the air ducts, the circulation of cold air in the system No Frost is disrupted. The cold simply cannot enter the upper part of the chamber, remaining blocked in the evaporator area. Clear space at the back wall and check that large packages (for example, three-liter jars) are not blocking the air holes.
For models with mechanical control, the position of the regulator is critical. If the knob is set to minimum, the evaporator will not reach the desired temperature. Try to smoothly move the regulator to the middle position and listen: after 15–20 minutes, the nature of the motor operation should change or the noise of flowing freon should appear.
Visual inspection of the back wall inside the refrigerator compartment can also give clues. If it is covered with a thick “coat” of ice, and the food is warm, it means that the defrosting cycle is broken. If the wall is dry and warm, and the compressor is hot and runs continuously, there is probably a freon leak or a clogged capillary tube.
Problems with the defrosting system No Frost
The most likely reason why the refrigerator Beko stopped freezing in the upper compartment when running compressor, lies in the malfunction of the automatic defrosting system. In the units No Frost frost accumulating on the evaporator is periodically thawed by a special heating element (heating element). If this process does not start, the ice coat grows, blocks the fans and blocks the cold supply channels.
The first suspect in this chain is Defrost heating element. It is a tube or spiral located directly on the fins of the evaporator. Over time, the spiral may burn out and the ice will stop melting. Checking the integrity of the heating element is carried out with a multimeter in continuity mode: if the device shows an open circuit, the part requires replacement. On models Beko Heating elements are often integrated into the plastic evaporator box, which requires careful disassembly.
The second important element is the defrost sensor (defroster). It is he who tells the control board that there is a lot of ice and it’s time to turn on the heating. If the sensor is stuck in the “ice has melted” position, the heating will never turn on. As a result, within a week or two, the evaporator becomes overgrown with a monolithic piece of ice, the fan begins to hum, touching the ice with its blades, and stops moving air.
- 🔍 Symptom: The fan in the freezer hums or crackles, but the refrigerator compartment is warm.
- 🔍 Symptom: A layer of ice or frost is visible on the back wall, although there should be a dry surface.
- 🔍 Symptom: The compressor runs longer than usual, trying to reach the temperature, but to no avail.
Third element systems - timer or control module. In older models Beko there were mechanical timers that could get stuck in the cooling cycle, ignoring the defrosting phase. In modern units, an electronic board is responsible for this, but it can also malfunction due to voltage surges. If the heating element and sensor are working, but defrosting does not occur, the problem may be in the control electronics.
⚠️ Attention: Do not try to break off the ice with a knife or screwdriver! The plastic of the evaporator in refrigerators Beko is very fragile in the cold. One awkward movement will lead to a breakdown of the freon channel, after which repairs will become economically unfeasible.
For diagnostics, you must completely defrost the refrigerator within 24 hours. If after turning it on it starts to freeze normally, but after 5-7 days the problem returns, it means that one of the elements of the defrosting system (heating element, sensor, timer) is faulty and requires replacement.
☑️ Diagnostics of the No Frost system
Fan malfunctions and air circulation
In refrigerators Beko with a system No Frost cold is generated in the freezer compartment, and it is forced into the upper compartment (refrigerator compartment) using a fan. If this fan stops, the cold air simply does not reach the food, remaining below. This is one of the most common reasons for the complaint “the refrigerator hums, but does not freeze.”
The reason for the fan stopping may be simple icing. When the defrost system does not work correctly, ice binds the blades and the fan motor burns out or becomes blocked. In this case, you may hear a characteristic crackling or humming sound from the freezer, which periodically subsides. Disassembling the back wall of the freezer will allow you to visually assess the condition of the unit.
The fan may also fail electrically. The motor winding could have burned out, or the plain bearings may have jammed due to exhaustion. The test is carried out by applying 220V voltage (or the corresponding DC voltage, depending on the model) directly to the fan contacts. If, when connected to the network, it does not rotate or make sounds, the part must be replaced.
It is also important to check the air channels. In some models Beko there are situations when the plastic damper that regulates the air flow gets stuck in the closed position. This could be a mechanical failure of the damper drive or a foreign object (for example, a label from a bag) getting into the channel.
If the fan is working properly and is spinning, but there is still no cold, it is worth checking the tightness of the air ducts. Sometimes, at the junctions of plastic boxes, gaps form through which cold air flows back into the freezer, bypassing the refrigeration compartment. Sealing the joints with sealant or foil tape can solve the problem.
How to replace a fan in Beko?
To replace the fan, you need to remove the back cover of the freezer, unscrew the motor mount, disconnect the power supply and install a new part. It is important to choose a fan with similar dimensions and direction of rotation of the blades, otherwise air circulation will be impaired.
Freon leakage and problems with the compressor
If defrosting did not help, and the fan is spinning properly, the undesirable scenario is a refrigerant leak or a compressor malfunction. Freon circulates in a closed loop, and if a microcrack forms in the tubes or connections, the gas gradually evaporates. Without a sufficient amount of refrigerant, the refrigerator cannot transfer heat from the chambers to the outside.
Detecting a leak visually is difficult, since freon is colorless and odorless. However, an indirect sign is the condition of the capacitor (grids on the back or sides). In a working refrigerator it should be evenly warm. If the grille is cold or only partially warm (for example, only at the beginning), this is a sure sign of a lack of freon.
The compressor is the “heart” of the refrigerator Beko. If it turns on, makes several strokes and turns off with a click (the thermal protection relay is triggered), this may indicate an interturn short circuit of the winding or jamming of the piston group. Also, the cause of such symptoms may be a faulty starting relay, which is inexpensive and easy to change, unlike the motor itself.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| The compressor is humming, but not starts | The starting relay is faulty or the compressor is jammed | Medium / High |
| The motor runs constantly, there is no cold | Freon leakage or capillary system clogged | High (requires a technician) |
| The refrigerator rarely turns on | The thermostat or temperature sensor is faulty | Low |
| A whistling or hissing is heard | Freon leak at the junction of the tubes | High (soldering required) |
It is impossible to eliminate a freon leak on your own, since this requires special equipment: a vacuum pump, a pressure gauge station and a supply of refrigerant. In addition, it is necessary to find the leak, solder it and correctly charge the system, observing the dosage. Attempts to “refuel” the refrigerator without eliminating the cause of the leak will only give a temporary effect.
A clogged capillary tube is another technical malfunction that manifests itself with similar symptoms. A plug from oil or moisture breakdown products forms in the system, preventing the circulation of freon. Cleaning requires disassembling the circuit and purging it with nitrogen, which is also a task for the service center.
Failures in the operation of electronics and sensors
Modern refrigerators Beko are stuffed with electronics that control all processes. If the main control module (board) receives incorrect data from the sensors, it may not command the compressor or fan to turn on. Most often, temperature sensors (NTC thermistors) located at different points in the chambers fail.
The temperature sensor in the refrigerator compartment can “lie”, telling the board that it is already -5°C inside, although in fact it is +15°C. Having received such a signal, the control module simply does not turn on the cooling. You can check the sensor by measuring its resistance with a multimeter and comparing the readings with a table of resistances for a specific temperature.
It is also worth paying attention to the condition of the control board itself. Power surges in the network often lead to failure of capacitors or controller firmware. Visually, this can manifest itself in the form of swollen capacitors, blackened tracks, or lack of response from indicators on the panel.
In some cases, rebooting the electronics helps. To do this, you need to unplug the refrigerator for 15–20 minutes. This will clear errors in the controller memory. If after switching on the system worked normally, a one-time software failure may have occurred.
⚠️ Attention: Manufacturers of household appliances can change the circuitry and location of sensors in different batches of the same model. When ordering spare parts, always use the full article number from the nameplate of your refrigerator, and not just the model.
If you do not have the skills to work with electronic components and a soldering iron, it is better to entrust board repair to specialists. Incorrect replacement of elements can lead to a short circuit and complete failure of the unit.
Algorithm of actions when a malfunction is detected
If you find that the refrigerator Beko does not freeze the upper compartment, act consistently so as not to aggravate the situation. Eliminate simple causes first, then move on to complex ones. Do not rush to call a technician for money if the problem can be solved by defrosting or replacing a cheap sensor.
The first step should always be complete defrosting. Even if you suspect a freon leak, defrosting will allow the system to rest and allow the compressor to cool. Leave the doors open for at least a day, preferably two. During this time, all hidden ice in the channels and on the evaporator will have time to melt.
After defrosting, turn on the refrigerator without food. Let it run for a few hours. If the cold appears and remains stable, it means that the problem was in the system No Frost (frozen channels). If the situation repeats after a week, look for a fault in the heating element, sensor or fan. If the cold does not appear even after defrosting, there is a likely leak or breakdown of the compressor.
- ✅ Step 1: Checking the settings and tightness of the door closure.
- ✅ Step 2: Complete defrosting within 24 hours.
- ✅ Step 3: Idle start and temperature monitoring.
- ✅ Step 4: Diagnostics of components (heating element, fan, sensors) if the problem repeats.
Remember that timely maintenance extends the life of equipment. Periodic cleaning of the drainage hole, checking the cleanliness of the condenser at the back and monitoring the condition of the seal will help avoid serious damage in the future.
Frequently asked questions (FAQ)
Is it possible to operate a Beko refrigerator if it does not freeze the top, but freezes the bottom?
Operation is possible temporarily, but is not advisable. The compressor will work harder, trying to cool the upper chamber, which will lead to overheating and shorten its service life. In addition, the food in the upper compartment will quickly deteriorate.
How long should defrosting last if the refrigerator is frozen?
For high-quality defrosting of the system No Frost a minimum of 24 hours is required. Ice in hidden channels and behind plastic panels melts slowly. An attempt to turn on the unit earlier may result in the remaining ice blocking the system again.
Why did the refrigerator start working after defrosting, but a week later it stopped again?
This is a classic sign of a malfunction of the automatic defrosting system. Most likely, the heating element of the evaporator burned out, or the defroster sensor or timer failed. Ice had accumulated again and was cutting off air circulation. The faulty part needs to be replaced.
Is it possible to replace the compressor on a Beko refrigerator yourself?
Theoretically, it is possible if you have the skills to solder copper pipes, evacuate the system and refill with freon. However, without special equipment (pump, station, scales) it is impossible to perform this work efficiently. An error in freon dosage will lead to breakdown of the new compressor.
What does the flashing temperature indicator on the Beko panel mean?
A flashing indicator usually signals that the temperature in the chamber is above normal. This can be either a consequence of a breakdown or a reaction to loading warm products or a door that is not tightly closed. If the blinking does not stop after the operation has stabilized, diagnostics are needed.
