The situation when the refrigerator Beko suddenly stops freezing, always takes you by surprise, because it threatens food spoilage. The owner begins to panic, not knowing whether the problem can be fixed on his own or whether it’s time to call a repairman. Often the problem lies not in a complex breakdown of the compressor, but in a simple electronics failure or contamination of the system.
In this article we will analyze in detail why the unit does not gain temperature and what to do first. We will look at both simple causes that can be eliminated without tools, as well as complex technical faults that require professional intervention. It is important to act consistently so as not to aggravate the situation.
Modern models Beko are equipped with complex electronics that are sensitive to power surges. That is why the first step should always be a basic diagnosis that excludes external factors. Only after this should you proceed to checking the internal components.
Primary diagnostics: checking power and settings
Before disassembling the unit, make sure that it is turned on at all. It sounds trivial, but often the problem lies in a loose plug or a tripped circuit breaker in the panel. Check whether the operation indicator on the control panel or inside the camera is lit. If the light does not light up when the door is opened, it means there is no power supply.
The second important point is the thermostat settings. In models with mechanical control, the temperature regulator may have accidentally moved to the "0" or "Min" position. In digital models Beko the operating mode could be lost due to a power surge in the network. Try to set average values, usually 3-4 degrees Celsius for the refrigerator compartment.
It is also worth paying attention to the position of the door. If the rubber seal is worn out or ice is frozen, the door will not fit tightly. Warm air enters the chamber, and the cooling system simply cannot cope with its removal. In this case the compressor runs without stopping, but there is no cold.
⚠️ Attention: If you notice that the refrigerator body is electrifying, immediately unplug the appliance and check the grounding of the outlet. The operation of such equipment is dangerous to life.
Don't forget to check if the "Vacation" or "Demo" mode (demonstration mode) is blocked. In demo mode, the refrigerator works, the light is on, but the compressor does not turn on, creating the appearance of operation in a store window. To disable this mode on different models Beko use different combinations of buttons, which you need to look for in the instructions.
Problems with the No Frost system and defrosting
If your Beko is equipped with a system No Frost, the lack of cold is often associated with a violation of the defrost cycle. In such models, the evaporator is hidden behind a plastic panel in the freezer. If the defrosting system fails, the evaporator becomes overgrown with ice, and air stops circulating through the chambers.
Symptoms of such a malfunction are that the compressor works, but there is no cold, and the fan in the back of the freezer may hum or the cracking of ice can be heard. The main elements that fail in the defrost circuit:
- ❄️ Defrost heating element —a heating element that could burn out.
- 🌡️ Defrost sensor—a thermistor that does not give a command to turn on the heating.
- ⏱️ A defrost timer or electronic module is a device that controls operating cycles.
To check these elements, you will need a multimeter. It is necessary to ring the heating element for an open circuit. If the resistance is infinitely high, it means the element is burnt out and requires replacement. The integrity of the sensor is also checked; its resistance should change depending on the temperature.
☑️ Diagnostics of the No Frost system
Often owners try to chip off the ice with a knife, which is strictly prohibited. Damage to the evaporator tubes will lead to freon leakage and costly repairs. It is best to let the ice melt naturally, leaving the doors open for a day.
Faults of the compressor and start relay
The compressor is the heart of the refrigerator. If it does not start or works intermittently, there will be no cold. A characteristic sign of a malfunction is a clicking sound when trying to start or a humming sound that ends abruptly. This indicates problems with starting relay or the motor itself.
The starting relay is a small plastic block that fits onto the contact group of the compressor. Inside there is a posistor or mechanical switch. Over time, the plastic cracks and the contacts burn. Replacing the relay is one of the simplest operations that you can do yourself.
If after replacing the relay the situation has not changed, and the compressor still clicks and does not start, there may be a problem in the motor windings or its mechanical jamming. In this case, the compressor needs to be replaced, which is a complex procedure that requires evacuation of the system and refilling the refrigerant.
Is it possible to replace the compressor yourself?
Replacing the compressor requires special tools: a burner, a pressure gauge station and a vacuum pump. Skills in soldering copper pipes and knowledge of types of refrigerants are also required. Without experience, there is a high risk of damaging the system or creating an explosive situation.
Pay attention to the temperature of the compressor housing during operation. If it is cold and does not vibrate, it will not start. If it is hot to the point where it is impossible to touch, but there is no cold, there may be an interturn short circuit or a problem with the valves.
Freon leakage: signs and consequences
Freon is a working fluid that circulates through the system, taking away heat. If a microcrack has formed in the circuit, the gas gradually evaporates. The main sign of a leak is the compressor runs constantlytrying to gain temperature, but there is no cold or it is very weak.
It is difficult to visually determine a leak, since freon is colorless and odorless. However, you may notice swelling in the rear wall of the refrigerator compartment or oily spots near the condenser tubes (black coil at the back). Oil escapes along with gas through the damage site.
If the leak occurred recently, repair may involve finding the damage site, sealing it and refilling it. If the refrigerator is old and the tubes are rotten, you often have to change the entire evaporator or overcook the circuit, which is not economically feasible.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| The compressor is humming, but does not start | Faulty start relay | Low |
| The refrigerator turns on for 5 minutes, then turns off | Thermal protection relay has tripped | Medium |
| Compressor is hot, no cold | Freon leak or capillary clogged | High |
| There is ice in the freezer, heat in the refrigerator | No Frost system malfunction | Average |
⚠️ Attention: Freon, although considered safe for the ozone layer in modern models, can cause suffocation when concentrated in a closed room. Do not solder pipes in a closed room without ventilation.
Clogged capillary tube
The capillary tube is a thin copper pipeline where freon is throttled. Over time, blockages may form in it due to oil oxidation products or moisture entering the system. This phenomenon is called "hydraulic blockage".
Signs of a blockage are similar to a leak: the compressor runs for a long time and overheats, the condenser (grid at the back) is only partially warm or cold. In this case, the pressure in the system is disturbed. It is almost impossible to clean the capillary on your own; purging with nitrogen under high pressure is required.
Often the blockage is accompanied by freezing of moisture at the narrowing of the tube. Tapping the tube may change the sound, but this is a temporary measure. The filter drier and capillary need to be professionally cleaned or replaced.
Faults in the electronic control module
In modern refrigerators Beko the electronic module is responsible for all processes. Voltage surges, moisture, or simply a manufacturing defect can damage it. Symptoms can be very different: the refrigerator does not turn on, one of the chambers does not freeze, the indicators blink chaotically.
Specific elements on the board often burn out, for example, a compressor control triac or a fan. Visually, this may look like blackening of the tracks or swelling of the capacitors. Repairing the module requires knowledge in electronics and the availability of soldering equipment.
In some cases, a complete reset (reboot) helps. To do this, you need to unplug the device from the outlet for 15-20 minutes. If the problem was a software glitch, this may help. If the module is physically burned out, it will need to be replaced or re-soldered.
⚠️ Attention: Electronic modules are sensitive to static electricity. Before touching the board, always remove the static charge by touching a grounded metal object.
When you need to call a technician
Not all faults can be fixed at home. If you checked the power supply, settings, defrosted the unit, but the problem remained, most likely the problem is in the technical part. A call to a specialist is necessary if it is required:
- 🛠️ Replacing the compressor or capillary tube.
- 🔧 Searching for and eliminating freon leaks followed by refilling.
- ⚡ Repair or replacement of the electronic control module.
- 🔩 Restoring the tightness of the circuit.
An attempt to independently repair complex equipment without experience can lead to the final failure of the unit. The master possesses special equipment: leak detectors, vacuum pumps, pressure gauges, which are inappropriate to buy for one-time use.
In addition, professional repairs provide a guarantee. If a leak occurs a month after your DIY soldering, there will be no one to blame. The certified service is responsible for the quality of the work performed.
Is it worth repairing an old refrigerator?
Repair is advisable if the cost of the work does not exceed 50-60% of the price of a new analogue. If you need to replace the compressor and refuel in an old refrigerator, it is often easier to buy a new one, since the resource of other components is also limited.
Prevention of breakdowns of the Beko refrigerator
In order for the refrigerator Beko to serve for a long time and not stop freezing, it is important to follow the operating rules. Regularly, at least once a year, defrost the unit (even the No Frost system) for prevention. Wipe the rubber seals and check their tightness.
Do not place hot pots inside the chamber - this creates an extra load on the compressor and leads to the formation of ice. Also, do not fill the refrigerator with food to capacity; air should circulate freely between them.
Keep the condenser grille at the back clean. Dust and animal hair act as a thermal insulator, preventing heat transfer. Vacuum the back wall once every six months, and the compressor will thank you by working in a gentle mode.
Frequently asked questions (FAQ)
Why does the Beko refrigerator hum, but does not freeze?
The humming means that the motor is trying to start. If there is no cold, the start relay may be faulty, the compressor is jammed, or there is a freon leak. Also, the cause may be a clogged capillary system.
How long should the No Frost system defrost?
It takes at least 24 hours to completely defrost the hidden evaporator in the No Frost system. If you defrost less, the ice may remain inside and the problem will not be solved.
Is it possible to use a refrigerator if it does not freeze well?
You can use it, but the food may spoil. However, operation of a faulty unit leads to overload of the compressor, which can permanently damage it. It is better to eliminate the cause.
What does a flashing indicator on a Beko refrigerator mean?
A flashing indicator usually indicates an increased temperature in the chamber. If after defrosting and setting it continues to blink, this is an error code, the decoding of which depends on the specific model (flashing sensors, problems with the fan, etc.).
Why is it warm in the refrigerator compartment, but normal in the freezer?
This is a classic sign of a malfunction of the defrost system (in No Frost models) or a freon leak. In the first case, the ice blocks the channels for supplying cold air to the upper chamber, in the second, there is not enough gas for the full cooling cycle.
