Understanding exactly how your a household assistant often becomes the key to its long life. When you know what is happening inside the steel case, it is much easier to diagnose strange sounds or temperature problems. Beko refrigerators They have earned popularity due to their reliability, but even the most reliable equipment requires proper operation.
The operation of any unit is based on a closed cycle, where the refrigerant circulates through a system of pipes, changing its state of aggregation. In models Beko this process is optimized for minimal energy consumption. Knowing the basic principles will help you avoid common mistakes that often lead to costly repairs.
Modern models may differ significantly from those produced ten years ago. If you're interested in a specific design for the 2010 model, keep in mind that technology has moved on. However, the fundamental physics remains the same: heat always moves from a warm object to a cold one, and the task of technology is to forcibly remove this heat.
The main elements of the refrigeration circuit
The heart of the system is compressorwhich creates the necessary pressure for the movement of freon. Refrigerators Beko most often use piston or inverter motors, each of which has its own design features. It is the quality of operation of this unit that determines how quiet and efficient the entire unit will operate.
After compression, the gaseous refrigerant enters condenser. This is the grille that can often be seen on the back of the device. Here the gas cools and turns into liquid, releasing heat to the environment. It is important that this element is always clean and well ventilated with air.
Then the flow passes through capillary tube or an electronic expansion valve. Here there is a sharp drop in pressure, which leads to cooling of the substance. This throttling principle is critical to creating low temperatures in the chamber.
⚠️ Attention: The capillary tube has a microscopic diameter. Any attempt to clean it yourself without a vacuum pump and special tools will lead to irreversible damage to the system.
In the evaporator, the refrigerant boils at low temperatures, actively absorbing heat from the internal space of the chambers. The cycle closes when freon gas returns to the compressor again. Full no-frost systems use one common evaporator, hidden behind the rear panel, unlike drip systems, where there are two.
Specifics of the No Frost cooling system
The technology No Frost, which is actively being implemented in the models Beko, completely eliminates the formation of ice on products. The air in the chamber is constantly circulated, passing through the evaporator, where it is cooled and dried. The flows are then evenly distributed across the shelves through special channels.
The key element here is the defrosting system. Periodically, based on a signal from a timer or electronics, it turns on The defrosting heating element. It melts the ice accumulated on the evaporator. The resulting water flows into a special pan located above the compressor, where it safely evaporates.
The fanplays an important role, which drives the air. If you hear that the motor is running, but there is no cold, it is possible that this particular unit has stopped or the air supply channel has frozen over. In such cases, diagnostics of defrost sensors is often required.
- 🌀 Uniform distribution of cold across all tiers of the chamber.
- 💧 No need for manual defrosting every six months.
- ❄️ Quick temperature restoration after loading products.
- 🔊 Possible increase in noise level due to fan operation.
It is worth noting that in some budget models Beko a mixed system is used: in the freezer - No Frost, and in the refrigerator compartment - drip. This allows you to reduce the cost of the device while maintaining the comfort of using the freezer.
Electrical circuit and controls
Responsible for intelligent control of the operation of all components control module. In older models it could be a simple mechanical timer, in new ones it could be a complex electronic board with a microprocessor. It is she who reads the sensor readings and makes the decision to turn on the compressor or heating element.
Temperature control is carried out using thermostats or thermistors. These elements constantly transmit data about the current climate inside the chambers. If you set the value +4°C, the electronics strives to maintain exactly this mode, adjusting the duration of the motor.
The electrical circuit also includes a starting relay and a protective thermal relay. They protect the compressor motor from overloads and power surges. If these components malfunction, the motor may hum, but not start, or turn off after a few seconds of operation.
| Component | Function | Typical malfunction |
|---|---|---|
| Thermostat | Adjustment temperature | Contact sticking, incorrect readings |
| Defrost heating element | Evaporator heating | Circle breakage, burnout |
| Defrost sensor | Evaporator temperature control | Change in resistance, open circuit |
| Defrost timer | Switching modes (in mechanics) | Stopping the mechanism, burning contacts |
Diagnostics of the electrical part requires the use of a multimeter. Checking the integrity of the circuits and the resistance of the sensors allows you to accurately determine the failed element without guessing on coffee grounds.
☑️ Electrical diagnostics
Design features of chambers and insulation
Internal volume of the refrigerator Beko divided into zones with different temperature conditions. The chamber walls are made of impact-resistant ABS plastic, which is resistant to low temperatures and easy to clean. Between the outer metal sheathing and the inner plastic there is a layer of thermal insulation.
Polyurethane foam is most often used as insulation, which is pumped in liquid form and hardens, forming a monolithic structure. The quality of foaming directly affects energy efficiency. If the insulation is damaged or defective, the refrigerator will operate without interruption.
The doors are equipped with magnetic seals around the perimeter. Their job is to ensure tightness. Even a small gap will lead to a constant flow of warm, humid air, which will cause abundant condensation and ice formation. Regular checking of seals is part of proper care.
⚠️ Attention: When replacing sealing rubber, it is important to warm up the new cuff with a hairdryer before installation. Cold rubber does not stretch well and may not fit into the groove, leaving gaps.
The shelves are made of tempered glass or strong wire. Some models have a system Multi Air Flowwhere the holes for the outlet of cold air are located at different levels. This prevents food from freezing at the back wall and ensures the same temperature on all shelves.
Types of compressors and their impact on operation
The compressor is the most expensive and important component. In refrigerators Beko you can find classic piston models that operate in a cyclic mode: turned on, cooled, turned off. They are quite noisy, but repairable and cheap to maintain.
More modern models are equipped with inverter compressors. They do not turn off completely, but only reduce the speed to maintain the temperature. This ensures silence, no temperature changes and significant energy savings. However, such motors are sensitive to voltage drops in the network.
The service life of inverter models is stated by the manufacturer to be up to 10 years or more. But it is worth remembering that their repair is often impractical: if they break down, they usually replace the entire assembly, which is expensive. If desired, a classic motor can be rebuilt in a workshop.
Why is a new refrigerator humming?
A new compressor may be louder than the old one due to the grinding in of parts. Also, increased hum may be caused by improper installation - check whether the body is touching furniture or walls.
When choosing between a conventional and an inverter model, it is worth weighing the advantages of silence and the price. If the refrigerator is in the kitchen-living room, where you spend a lot of time, overpaying for the silence of the inverter is quite justified.
Frequent problems associated with the device
Knowledge of the device helps to understand the causes of breakdowns. For example, if ice freezes in the freezer and the food in the freezer melts, the drainage hole is most likely clogged. The defrosting water does not leave, freezes and blocks the operation of the fan. No Frost Ice freezes, and the food in the freezer melts; most likely, the drainage hole is clogged. The defrosting water does not leave, freezes and blocks the fan.
If the refrigerator Beko stops freezing, but the motor runs constantly, this may indicate a freon leak. There is no pressure in the system, and the refrigerant simply circulates without cooling. It can only be treated by calling a technician with equipment to find leaks and refill them.
An extraneous knock or vibration often indicates problems with the compressor shock absorbers or that the refrigerator is not level. Adjusting the legs is the simplest procedure that you can do yourself using a level.
- 🔊 Loud hum - a problem with the compressor or fan.
- 💧 Water on the floor - clogged drainage or disconnected tube.
- 🌡️ Low cold - wear of the seal or lack of freon.
- 💡 The light does not come on - the lamp is burned out or the door switch is faulty.
You should not ignore the first signs of a malfunction. Timely contact with specialists often allows you to get away with easy prevention, instead of replacing expensive components.
FAQ details: answers to questions about the device
Where is the evaporator in the Beko No Frost refrigerator?
The evaporator is hidden behind a plastic panel on the back wall of the freezer. To access it, you need to unscrew several screws and remove the panel. It is on this element that ice freezes, which is then removed by the heating element.
Is it possible to replace the thermostat yourself?
Technically, this is possible if you have skills in working with electricians and tools. However, after replacement, fine tuning or calibration is often required, which is difficult to perform without special equipment. An error can lead to spoilage of food.
Why does the back wall of the refrigerator become covered with ice?
In drip models this is a normal process: moisture freezes and flows down when the compressor is turned off. If the ice does not melt and turns into a fur coat, check the tightness of the door closure and the integrity of the seal. The thermostat may also stick.
How often should defrost occur?
In models with a timer, defrost usually occurs every 8-12 hours of compressor operation. In electronic models, the interval may vary depending on the algorithm embedded in the control board and the frequency of door opening.
What is a freshness zone and how is it designed?
This is a separate compartment (usually in the lower part of the refrigerator compartment), where the temperature is maintained at about 0°C and high humidity. Structurally, this can be implemented with a separate air supply damper or an insulated container with its own circulation system.
