The Atlant refrigerator does not cool enough: how to make it colder?

Has your refrigerator Atlant become worse at cooling, and are food spoiling faster than before? The problem may lie in either incorrect settings or technical faults. Before calling a technician, try to figure out the reasons yourself and eliminate them.

In this article we will look in detail at how to increase cooling capacity refrigerator Atlant —from basic temperature settings to diagnosing the compressor and thermostat. You will learn what manipulations you can do yourself, and in which cases you cannot do without professional help. We will pay special attention to models with a system No Frost and drip defrosting, as they require a different approach.

Important: if the refrigerator Atlant stops freezing completely (temperature in the chambers is above +10°C), this may indicate a serious breakdown. In this case, it is better to immediately contact the service center. Our recommendations are relevant for situations where there is cooling, but it is insufficient.

1. Checking the current temperature settings

The first thing you need to do is make sure that the refrigerator is set to the optimal setting. In models Atlant temperature control is carried out using a mechanical thermostat (in old models) or an electronic panel (in new ones).

For most household refrigerators Atlant recommended values:

• 🥶 Refrigerator compartment: +2...+5°C (optimally +3...+4°C).
• ❄️ Freezer compartment: −18...−24°C (for long-term storage).

If the regulator is set to the minimum value (for example, "1" or "Min"), the compressor will turn on less often, which will lead to insufficient cooling.

How to change the settings:

• 🔄 In models with mechanical control (for example, Atlant XM-4021-000) turn the thermostat knob clockwise one or two notches. Typically, the scale has values from “1” (warmest mode) to “7” (maximum cold).
• 📱 In refrigerators with electronic display (for example, Atlant NM 6204-100) press the button Temp or Fridge, then set the desired value using the "+"/"−" arrows.

After change settings, wait 6–12 hours - during this time the temperature will stabilize.

⚠️ Attention: If the temperature in the freezer is set below −24°C, this increases the load on the compressor and increases energy consumption. Optimal balance for Atlant — −18°C.

2. Diagnostics of the door sealing rubber

One ​​of the most common causes of poor cooling is wear or contamination of the seal. If the rubber band does not fit tightly to the body, warm air penetrates inside the chamber, causing the compressor to work in increased mode. Over time, this leads to overheating and reduced cooling efficiency.

How to check the seal:

1. Close the refrigerator door.
2. Take a sheet of A4 paper and try to push it between the rubber band and body.
3. If the sheet passes freely or falls out, the seal requires replacement or repair.

Also inspect the elastic band for cracks, tears or traces of mold. In models Atlant older than 5 years, the seal often loses its elasticity.

What to do if the seal is faulty:

• 🧼 Cleaning: Wipe the rubber with warm soapy water, then lubricate with silicone grease (for example, WD-40 Specialist). This will temporarily restore elasticity.
• 🔥 Repair: If the seal is deformed in only one place, you can heat it with a hairdryer (temperature 60–70°C) and give it the correct shape.
• 🛠️ Replacement: For models Atlant fit original seals with article numbers 54.01.001 (for single-chamber) and 54.02.001 (for double-chamber). Cost - from 800 to 1500 rubles.

3. Optimizing product loading

Many users do not realize that improper placement of products can impair the circulation of cold air. In refrigerators Atlant with a system No Frost the air is distributed throughout the chamber using fans, and in models with drip defrosting, the cold comes from the back wall. If products block these zones, the temperature rises.

Loading rules:

• 🥦 Do not place products close to the back wall - leave a gap of 2-3 cm for air circulation.
• 🥛 Do not overload the shelves: in models Atlant with a volume of up to 200 l, the maximum load on the shelf is 10 kg.
• 🍖 Separate hot and cold foods: if put a warm pan in the refrigerator, place it on the bottom shelf (it’s colder there).
• 🧊 Do not store liquids in open containers - this increases humidity and load on the evaporator.

Pay special attention to the freezer: if ice or a snow coat covers the evaporator thicker than 5 mm, this impairs heat transfer. In models Atlant with manual defrosting (MHM-1708, MX-2824), it is recommended to defrost every 3-4 months. In systems No Frost 1-2 times a year is enough.

⚠️ Attention: If ice forms in the freezer despite the system No Frost, this may indicate a malfunction of the evaporator heater or defrost sensor. In this case, diagnostics are required.

4. Cleaning the condenser and ventilation grilles

The condenser (the grille on the back wall of the refrigerator) is responsible for removing heat from the refrigerant. If it is clogged with dust, fluff or dirt, heat transfer deteriorates and the compressor starts working without stopping, without having time to cool the chambers. In models Atlant the capacitor is located at the back (in old models) or at the bottom (in new ones, for example, Atlant NM 6021-080).

How to clean the capacitor:

1. Unplug the refrigerator and move it away from the wall.
2. Take a vacuum cleaner with a narrow attachment or a soft brush and carefully remove dust from the grille.
3. Wipe the surface with a damp cloth, then dry.
4. Check that there is a gap of at least 5 cm between the condenser and the wall.

In refrigerators with the system No Frost you also need to clean the ventilation holes inside the chambers (usually they are located on the back wall or between the shelves).

Also make sure that compressor (black cylinder at the bottom) does not overheat. Normally it should be warm, but not hot. If a strong hum or vibration is heard during operation, this may indicate wear of the motor.

What will happen if you do not clean the condenser?

If the condenser is heavily soiled, the refrigerator compressor Atlant begins to operate in mode overload, which leads to:

• Increased energy consumption by 20-30%.
• Reduced compressor service life (risk of breakdown after 3-5 years instead of 10-15).
• Deterioration of cooling by 3–5°C even with maximum thermostat settings.

In critical cases, the refrigerator may turn off due to overheating (thermal protection is triggered).

5. Checking the operation of the thermostat and sensors If the refrigerator does not cool despite the correct settings and cleanliness, the problem may be (in mechanical models) or (in electronic models). These elements are responsible for turning the compressor on/off. If they malfunction, the motor either works without stopping or turns on too rarely.

If the refrigerator Atlant does not cool despite correct settings and cleanliness, the problem may be thermostat (in mechanical models) or temperature sensors (in electronic). These elements are responsible for turning the compressor on/off. If they malfunction, the motor either runs non-stop or turns on too rarely.

How to diagnose a thermostat:

• 🔧 In models with a mechanical control (Atlant XM-4424-000) the thermostat is located inside the chamber, behind the plastic panel. To check it, you need to:
1. Disconnect the refrigerator from the network.
2. Remove the thermostat protective casing (usually secured with latches).
3. Ring the contacts with a tester in resistance testing mode. At room temperature, the resistance should be close to zero.

📊 In electronic models (Atlant NM 6205-100), a sensor malfunction is displayed on the display as an error E1, E2 or a flashing light. For the exact error value, see the instructions.

If the thermostat is faulty, it must be replaced. For models Atlant thermostats are suitable K59-L1433 (for single-chamber) and Danfoss 077B6340 (for double-chamber). The average cost is 1200–2500 rubles. You can do the replacement yourself, but if you are not confident in your skills, it is better to contact a specialist.

6. Checking the refrigerant and compressor If all the previous steps did not help, the problem may lie in Freon or freon. Refrigerators

If all the previous steps did not help, the problem may lie in refrigerant leak (freon) or compressor wear. In refrigerators Atlant use freons R134a (in new models) and R12 (in old ones). If there is a leak, gas escapes through microcracks in the tubes, and the system stops cooling.

Signs of a freon leak:

• 🔊 The compressor works non-stop, but there is no cold.
• ❄️ The condenser (grid at the back) remains cold.
• 💧 An oily liquid appears on the back wall of the refrigerator (this is oil leaking from the system).

It is impossible to eliminate the leak on your own - special equipment for vacuuming and filling is required. The average cost of the service in service centers is 3500–6000 rubles.

If the compressor buzzes, but does not start, this may indicate:

• 🔋 Faulty start relay (the part costs 800–1200 rubles).
• 🔌 Problems with the motor winding (replacement of the compressor is required, price - from 5000 rubles).
• 📉 Reduced voltage in the network (less than 200 V).

To diagnose the compressor, the master uses tester and pressure gauge. Models Atlant most often install compressors Danfoss or Secop, which are considered reliable, but also wear out over time.

⚠️ Attention: If a refrigerator Atlant turns off 1-2 minutes after startup, this may be triggered thermal protection due to overheating. The cause is often a fan malfunction (in models with No Frost) or a clogged capillary tube. Do not try to start the refrigerator again - this may lead to a fire.

7. Additional ways to improve cooling

If your refrigerator is working properly, but you need to temporarily increase its cooling capacity (for example, in hot weather or when loading a large amount of food), use these tips:

• ❄️ Super Freeze mode: Models Atlant with electronic control (NM 6205-100, NM 4626-100) have an accelerated cooling function. Activated by button Super Freeze for 2–6 hours.
• 🌡️ External temperature: Do not place the refrigerator next to the stove, radiator, or on the sunny side. The optimal room temperature is +16…+32°C. At +35°C and above, cooling efficiency drops by 30–40%.
• 🔄 Ventilation: Make sure that there is a gap of at least 5 cm between the refrigerator and the wall. Built-in models Atlant require forced ventilation (you can install a small fan).
• 🧊 Ice in the freezer: If there is little food in the freezer, put 2-3 bottles of water there. They will act as cold accumulators.

For models with the system No Frost it is useful to clean the drainage hole (located on the back wall of the refrigerator) once every six months. A clogged vent causes water to accumulate and humidity to build up, which impairs cooling. For cleaning, use a cotton swab or a syringe with warm water. If the refrigerator does not cool despite all measures, the reason may be a thin channel through which freon circulates. This problem requires professional repair using hydraulic equipment. Independent attempts at cleaning can lead to complete breakdown of the system.

FAQ: Frequently asked questions about Atlant refrigerators

❓ Why does the Atlant refrigerator work non-stop, but not freezing?

This is a typical sign freon leaks or thermostat malfunctions. If the compressor is hot and humming, but there is no cold, there is likely not enough refrigerant in the system. Another possibility is that the capillary tube is clogged. In both cases, diagnostics by a specialist is required.

❓ What temperature regime is optimal for the Atlant refrigerator in the summer?

In the summer it is recommended to install it in the refrigerator compartment +2…+3°C, and in the freezer −20…−22°C. If the room is hot (above +30°C), you can temporarily lower the temperature by 1-2 degrees, but do not forget to return the settings back so as not to overload the compressor.

❓ Is it possible to fill freon into the Atlant refrigerator yourself?

No, it is dangerous. Charging refrigerant requires special equipment (vacuum pump, gauge manifold) and skills. Incorrect filling can lead to hydraulic shock the compressor or explosion of the freon cylinder. Contact the service center.

❓ Why does ice build up in the Atlant refrigerator with No Frost?

In systems No Frost ice on the evaporator is a sign of a malfunction defrost heater or defrost sensor. Also check to see if the fan is blocking ice or food. If after defrosting the problem repeats, parts need to be replaced.

❓ How much does it cost to repair a compressor in an Atlant refrigerator?

The cost depends on the model and type malfunctions:

• Replacement of the start relay - 1000-1500 ₽.
• Repair of the compressor winding - 2500-4000 ₽.
• Complete replacement of the compressor - 5000-8000 ₽ (including work and refilling freon).

In service centers Atlant fixed prices apply, but prices may vary depending on the region.
