The situation when Atlant refrigerator stops freezing in the freezer always takes you by surprise. Food begins to melt, there is a risk of stock spoilage, and panic reigns in the kitchen. Most often, owners notice the problem too late, when the ice in the chamber has already turned into water, and there is defrosted meat on the shelf.
Before calling a technician or running to the store for new equipment, it is worth conducting an initial diagnosis. Many of the reasons why Atlant freezer loses cold can be eliminated yourself or the severity of the breakdown can be understood. It is important not to ignore the first signs: mild cold, the formation of a “fur coat” or, conversely, the complete absence of frost.
In this article we will analyze in detail the main components that are responsible for cooling. You will learn how to distinguish a simple operating error from a complex technical failure. Timely detection problems will save you money and nerves.
Primary diagnosis: why the cold disappeared
If you opened the door and felt that there It's warm, don't rush to sound the alarm. Sometimes the reason lies in banal things. Incorrect installation or incorrect settings could lead to this result. Check if the refrigerator is too close to the wall or radiator.
Pay attention to the thermostat. If it is set to the minimum position, the compressor may simply not turn on often enough to maintain a low temperature. It is also worth checking the tightness of the rubber seal ⚠️ Attention: If you recently transported the refrigerator lying down, you can turn it on no earlier than 4-6 hours later. The oil must drain into the compressor, otherwise the equipment will fail. to the body
⚠️ Attention: If you recently transported the refrigerator lying down, you can plug it into the network no earlier than after 4-6 hours. The oil must drain into the compressor, otherwise the equipment will fail.
Carefully inspect the back wall of the freezer. If there is no frost or ice and the unit itself is running quietly, there may be a refrigerant leak. If a huge lump of ice is frozen, but there is no cold, the problem is in the defrosting system.
Problems with the No Frost and defrost system
Modern models Atlant are often equipped with a system No Frost. If your refrigerator is of this type, but has stopped freezing, most likely the defrosting system has failed. Ice blocks the channels through which cold air should enter the chamber.
The main culprits in this situation are the evaporator heating element, defrost sensor or timer. When one of these elements breaks, the evaporator becomes coated with ice, the fan cannot move air, and the temperature in the freezer rises. In the refrigerator compartment, it may be normal, but the freezer will “cry.”
- ❄️ Defrost heating element - a heating element that could burn out and stop melting the ice.
- ⏱️ Timer - a mechanism that does not switch the unit to defrost mode at the right time.
- 🌡️ Temperature sensor - “lies” to the controller, claiming that there is no ice, although it has already blocked the air ducts.
For diagnostics, “old-fashioned defrosting” is often required. Leave Atlant refrigerator turned off for 10-12 hours with the doors open. If after turning it on it works normally, but after a couple of days the problem returns, the diagnosis is confirmed.
How to check the heating element with a multimeter?
To check the heating element, you need to remove the back panel of the freezer, find the heating element and ring it with the probes of the multimeter. The resistance should be within normal limits (usually 200-400 Ohms), if the device shows a break, the heating element has burned out and requires replacement.
Freon leakage and problems with the compressor
The most unpleasant scenario is refrigerant leak. Freon circulates in a closed circuit, and if a microcrack appears in the tubes or evaporator, the gas evaporates. Without freon, heat exchange does not occur, and the freezer ceases to perform its function.
Signs of a leak are often visible visually: there may be oily spots on the rear radiator grille (oil comes out along with gas). Also, the compressor may work non-stop, trying to gain temperature, but never turn off. In some cases, on the contrary, it is silent.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| The compressor hums, but does not start | Malfunction of the starting relay or wedge compressor | Average |
| The refrigerator works constantly | Freon leakage or compressor wear | High |
| It’s warm in the freezer, normal in the refrigerator | Clogged capillary tube or leak in the evaporator | High |
| A gurgling sound is heard | Remaining freon or air in the system | High |
If you suspect a leak, self-repair is impossible without special equipment. You need a vacuum pump, a pressure gauge station and a supply of the correct refrigerant. Attempts to simply “top up” the refrigerator without finding and eliminating the leak will only give a temporary effect.
⚠️ Attention: Freon used in household refrigerators can be explosive or toxic if mishandled. Work on finding leaks and refilling must be carried out by a certified specialist.
Clogged capillary tube
Another technical reason why the Atlant freezer does not freeze is a clogged capillary tube. This is the thinnest channel through which freon enters the evaporator under pressure. Over time, oil oxidation products or ice plugs may form in the system.
If clogged, the refrigerant circulation is disrupted. The pressure at the compressor inlet drops and the outlet pressure rises. The unit may hum, trying to push freon, but there will be no cold. Often, the condenser (grid at the back) only partially heats up.
It is difficult to diagnose a blockage at home. Typically, technicians try to “push” the system with increased nitrogen pressure. If this does not help, you need cleaning the capillary or replacing it, which is a labor-intensive procedure.
Malfunction of the thermostat and electronics
In models with mechanical control, the thermostat is responsible for turning the compressor on and off. This is a simple “twist” inside the camera. If its contacts are burnt or the sensitive element has lost its properties, the signal to start the motor simply does not arrive.
In more modern models Atlant with electronic control, the control module is responsible for all processes. Power surges often cause failure of electronic components. In this case, the refrigerator may behave chaotically: it either freezes too much, or stops cooling completely.
- 🔌 Problem with the wiring — oxidation of contacts or breakage of the wire going to the sensor.
- 💻 Board failure —reflashing or replacement of the control module is required.
- 🎛️ Thermostat malfunction —the compressor does not receive the start command.
You can check the thermostat by closing its contacts directly (for mechanical models). If after this procedure the compressor starts and gets cold, then the regulator needs to be changed. However, it is better not to experiment with electronics without knowledge.
☑️ Diagnostics before calling a technician
Operating errors and external factors
Technology is not always to blame. Often, users themselves create conditions under which the refrigerator cannot freeze. For example, loading a freezer with hot food causes the compressor to wear out, which can lead to overheating and stopping.
The location of the unit also affects it. If Atlant stands close to a wall or in a niche without ventilation, heat is not removed from the condenser. The cooling efficiency drops, and the freezer becomes warmer than normal.
Frequent and prolonged opening of doors in hot weather also disrupts the temperature regime. Moist air enters the chamber, which instantly turns into ice on the evaporator, blocking heat exchange.
⚠️ Attention: Do not place the refrigerator near the stove, oven, or in direct sunlight. This critically affects the operation of the cooling system and can lead to compressor failure.
When professional repairs are needed
If simple methods like defrosting and checking settings did not help, then the problem is deeper. The intervention of a professional is necessary when it is necessary replacing a compressorto search for a freon leak or repair an electronic board.
The master has tools for accurate diagnostics: leak detectors, pressure gauges and testers. He will be able to determine whether it is worth repairing the old unit or whether it is more economically feasible to buy a new one. Often, repairing the “heart” of a refrigerator can cost up to 70% of the price of new equipment.
Do not delay contacting service. If the freezer is warm, food spoils quickly, and an empty compressor consumes excess electricity and wears out.
Why is the Atlant freezer covered with ice, but does not freeze?
This is a classic sign of a malfunction of the defrost system in No Frost models. Ice froze on the evaporator and blocked the circulation of cold air. It is necessary to replace the heating element, sensor or timer.
How long should the refrigerator cool down after defrosting?
After complete defrosting (at least 10-12 hours) and turning on the network, Atlant refrigerator it takes from 2 to 6 hours to reach operating temperature. Do not load food into the freezer in the first couple of hours.
Is it possible to use a refrigerator if it does not freeze?
You can use the unit as a cabinet, but you cannot leave it on if there is a malfunction (especially if there is a freon leak or a problem with the compressor). This will lead to the final failure of the motor and a fire hazard.
What does it mean if the compressor clicks and does not start?
Clicks indicate attempts by the starting relay to start the motor. If they are not followed by a hum, the start relay may have burned out, the compressor has jammed, or the motor winding has burned out.
