Reduced efficiency of refrigeration equipment is one of the most common problems faced by owners of household appliances. When there is no longer enough cold in the chamber, food begins to deteriorate faster, and an unpleasant odor or condensation may appear inside. The equipment of the Belarusian brand Atlant is characterized by high reliability, but even time-tested models require attention to details of operation.
Before calling a technician or looking for ways to forcibly increase the operation of the compressor, it is necessary to carry out primary diagnostics. Often the reason lies not in a breakdown, but in a banal violation of operating rules or lost settings. Understanding the principles of operation thermostat and air circulation will help you independently return the unit to its previous power.
In this article we will analyze all the available methods of increasing cooling capacity: from simple defrosting actions to complex technical interventions. You will learn how to set the parameters correctly, what to look for when inspecting seals, and when a situation requires professional intervention. A competent approach will extend the life of your Atlant refrigerator and preserve the freshness of products.
Primary diagnostics and leak testing
The very first step that needs to be taken if you notice that the refrigerator has stopped freezing is a thorough inspect the chamber for cold leaks. Even a microscopic gap in the door seal can negate the work of the most powerful compressor. Air from the room, getting inside, heats the food and causes the system to work in emergency mode.
⚠️ Attention: If the rubber door seal is deformed, cracked, or debris simply sticks to it, the tightness is broken. Do not ignore visual defects in the cuff, as they lead to freezing of the evaporator and failure of the compressor.
Checking the tightness can be carried out using a simple but effective folk method. Take a regular sheet of A4 paper and clamp it with the refrigerator door around the entire perimeter. If the sheet is pulled out easily and without resistance, it means that the seal does not fit tightly in this place. In some cases, it is enough to simply wash and degrease the rubber to restore its elasticity.
Particular attention should be paid to the corner where the temperature sensor is installed. It is in this area that gaps most often form due to the design features of the door. Also check the hinges: if the door is warped, it will not fit tightly and the cold will escape out. Adjusting the hinges is a simple procedure that you can often do yourself using a wrench. thermostat or temperature sensor. It is in this area that gaps most often form due to the design features of the door. Also check the hinges: if the door is warped, it will not fit tightly and the cold will escape out. Adjusting the hinges is a simple procedure that you can often do yourself using a wrench.
Make sure you are not overloading the shelves. If there are too many products, they may prevent the door from closing tightly. In addition, warm food placed in storage will sharply increase the internal temperature, forcing the unit to work at its maximum capacity. Allow the food to cool to room temperature before storing it in the chamber.
The next important aspect is the location of the unit. If Atlant refrigerator stands close to a wall or in a niche, the ventilation of the condenser is disrupted. The rear grille must breathe to effectively dissipate heat. The minimum distance from the back wall to the wall should be at least 5-7 centimeters.
Setting the thermostat and operating modes
The central element of temperature control in refrigerators Atlant is the thermostat. In older models this is a mechanical rotary switch with numbers from 1 to 7, in new ones it is an electronic control panel. Many users mistakenly believe that the number “1” means the most severe cold, although in fact the opposite is true: the higher the number, the lower the temperature inside the chamber.
If you want to add cold, you need to turn the knob towards the maximum value (usually 6 or 7). However, this must be done with caution. Setting the mode to maximum causes the compressor to work almost without stopping, which leads to increased energy consumption and accelerated wear of parts.
In models with a system No Frost or “Crying evaporator” the settings can be more subtle. Here it is important not only to set the overall temperature, but also to check the operation of the dampers that regulate the flow of cold air. If the damper is stuck in the closed position, the cold simply will not flow into the main chamber, even if the freezer is working perfectly.
Electronic models Atlant are characterized by the ability to set the exact temperature in degrees Celsius. The optimal value for the main camera is considered to be from +2 to +4 degrees. A decrease below +1 degree can lead to freezing of vegetables and spoilage of dairy products, so do not chase extreme values unnecessarily.
| Knob position | Temperature regime | Recommendation for use | Impact on the compressor |
|---|---|---|---|
| Minimum (1-2) | +5...+7 °C | In summer or at low load | Economy mode, rare starts |
| Average (3-4) | +3...+5 °C | Normal daily operation | Standard duty cycle |
| Maximum (5-7) | 0...+2 °C | With a large load of products | Intensive work, high wear |
| Shutdown (0) | Ambient temperature | Only during defrosting or washing | The compressor does not work |
There is a common misconception that constantly keeping the regulator at maximum extends the life of products. In fact, this puts unnecessary stress on the system. It is better to ensure proper air circulation and average settings than to keep the unit in stress mode.
The effect of defrosting on cooling performance
One of the most common reasons that the refrigerator stops freezing normally is the formation of an ice “coat” on the evaporator. Even in models with a system No Frost, where automatic defrosting is provided, failures may occur. In classic models with a “crying” wall, ignoring the need to defrost the unit leads to a catastrophic drop in efficiency.
Ice is an excellent heat insulator. When the evaporator is covered with a thick layer of ice, it stops effectively removing heat from the chamber. The compressor hums, trying to compensate for the lack of cold, but the result remains zero. In such a situation, the only correct solution is complete defrosting.
☑️ Rules for proper defrosting
The defrosting process takes time. Don't try to speed it up by using a hairdryer or hot water, especially if you have a model Atlant with an aluminum evaporator. Sudden temperature changes can deform thin tubes or damage the coating, causing refrigerant leakage. Let the ice melt naturally.
⚠️ Attention: Never use sharp objects (knives, screwdrivers) to chip ice. A broken evaporator is an expensive repair involving refilling it with freon, which can cost half the price of a new refrigerator.
After defrosting, be sure to wipe all surfaces dry and leave the refrigerator empty for a couple of hours. This will allow the system to stabilize and reach the desired temperature before loading food. Often after such a procedure Atlant refrigerator it starts working like new again, and the question “how to add cold” disappears by itself.
If you are the owner of a two-compressor model, remember that you can defrost the chambers independently of each other. However, if a problem with cold is observed in both chambers, most likely the problem is not ice, but a more serious malfunction, for example, a freon leak or a compressor breakdown.
Checking the ventilation and air circulation system
In modern models Atlant, especially in series with the system No Frost, proper air circulation is critical. The cold is generated in a separate compartment (usually behind the back wall of the freezer) and distributed throughout the freezer by a fan. If this process is disrupted, the cold simply does not reach the products.
The first thing to check is whether the ventilation holes are blocked. There are special grilles or holes on the back wall of the main chamber and in the freezer. They should not be crowded with pots, bags or bottles. The air must circulate freely.
The fan responsible for blowing cold air may fail or freeze. If you hear the compressor running, but the inside is quiet and there is no characteristic air flow noise, the fan may have stopped. In some cases, it may become jammed with ice due to a malfunction of the defrost system.
How to check the operation of the fan?
To check, remove the back panel in the freezer (after first unplugging the refrigerator). Visually inspect the fan for ice. If there is no ice, you can apply power briefly and see if the blade spins. Be careful with electricity!
It is also worth checking the condition of the air ducts. In rare cases, a foreign object (for example, a piece of product packaging) may become lodged in them, blocking the flow. Cleaning the air ducts often restores normal operation of the refrigerator without the need for complex repairs.
Pay attention to the location of the products. Do not put hot or warm food in the refrigerator. This not only disrupts the temperature regime, but also creates powerful upward currents of warm air, which can disrupt the operation of sensors and interfere with the normal circulation of cooled masses.
Technical reasons for reducing cold: freon and compressor
If all of the above methods did not help, and you are wondering how to add cold in the refrigerator Atlant, but the settings and cleanliness are normal, there was probably a technical malfunction. The most common reason is a refrigerant (freon) leak.
Freon is the working fluid of the refrigeration cycle. If its amount in the system decreases, cooling efficiency decreases. First, the refrigerator begins to freeze worse, then it stops turning off, trying to compensate for the shortage, and eventually stops cooling altogether. It is impossible to add freon yourself: specialized equipment is required to find leaks, solder and evacuate the system.
Another possible reason is a compressor malfunction. This is the "heart" of the refrigerator. If it works, but does not create the required pressure, or if one of the valves fails, the circulation of freon is disrupted. Symptoms may be a quiet hum, overheating of the compressor housing, or, conversely, its cold state when the engine is running.
Clogged capillary tube is another technical problem. An ice or oil plug may form in the freon circulation system, which blocks the flow of refrigerant. In this case, one part of the refrigerator may freeze normally, while the other may remain warm, or the unit will operate jerkily.
| Symptom | Probable cause | Solution method | Complexity |
|---|---|---|---|
| The compressor does not turn on | Malfunction of the start relay or thermostat | Replacement of the part | Average |
| It hums, but does not freeze | Freon leak or blockage | Call a technician, refill | High |
| Freezes only at the wall | Lack of freon | Search for leaks, refill | High |
| Gets very hot on the sides | Normal operation or condenser contamination | Cleaning the rear grille | Low |
Diagnostics of these problems at home is limited. You can listen to the operation of the motor, check the heating of the tubes (one should be warm, the other cold), but only a specialist with a manometric manifold will make an accurate diagnosis.
Seasonal characteristics and external factors
The efficiency of the refrigerator Atlant directly depends on environmental conditions. The temperature in the room where the unit is located plays a key role. If the kitchen is hot in the summer (+30°C and above), it is physically more difficult for the refrigerator to remove heat. The condenser overheats and the efficiency of the cycle drops.
In winter, the situation may be the opposite. If the refrigerator is located on an unheated loggia or in a cold corridor, where the temperature drops below +10°C, the oil in the compressor thickens, and the thermostat may not “see” the need to turn on the motor, since the room is already cold. This can lead to food defrosting.
Air humidity also affects the operation of the equipment. In very humid rooms (for example, in a private house without ventilation), condensation may form more actively on internal parts, which leads to faster accumulation of ice and the need for frequent defrosting.
Keep the rear grill clean. Dust, lint and pet hair settle on the condenser and act like a blanket, preventing heat from escaping. Regular (once every six months) cleaning the back of the refrigerator with a vacuum cleaner or brush is a great way to “add cold” without unnecessary settings.
⚠️ Attention: Technical characteristics and operating requirements may vary slightly depending on the specific series and year of manufacture of your Atlant refrigerator. Always check the official user manual for your model so as not to violate the terms of the warranty.
Frequently asked questions (FAQ)
Is it possible to add an additional fan inside the Atlant refrigerator to increase the cold?
It is strictly not recommended to make changes to the design of a household refrigerator. Installing third-party fans will disrupt the designed aerodynamics of air flow, can lead to freezing of food and create an extra load on the electrical network. In addition, this will void the warranty.
Why did the Atlant refrigerator stop freezing after defrosting?
If after defrosting the cold did not appear within 2-3 hours, the evaporator may have been damaged during cleaning (pierced with a knife) or water got inside, causing a short circuit in the control circuit. The thermostat could also have failed.
How can you tell if there is little freon in the Atlant refrigerator?
Signs of a freon shortage are: weak cold only near the back wall, compressor operation without stopping, only partially hot condenser (grid at the back), as well as the absence of characteristic gurgling or hissing during operation.
Does the amount of food in the refrigerator affect the cooling rate?
Yes, it does. An empty refrigerator cools faster, but also heats up faster when the door is opened. A fully stocked refrigerator stays cold longer, but requires more time and energy to initially cool down. The optimal load is about 70% of the volume.
Is it possible to use the "Super Freeze" mode constantly?
No, the "Super Freeze" (or Max) mode is designed for short-term freezing of large quantities of fresh food. Constant use of this mode leads to overheating of the compressor, increasing the electricity bill and reducing the service life of the appliance.
