Two-chamber refrigerators Atlant are known for their reliability, but sometimes owners encounter a problem: the freezer is working fine, but in the main compartment the temperature is higher than the recommended +4°C. Or vice versa - the food in the refrigerator freezes slightly, although the regulator is set to the minimum value. In this article we will look at how to properly intensify cooling in the refrigerator Atlant without the risk of breakdown, what settings are responsible for the temperature regime and when you should contact a specialist.
It is important to understand: simply turning the thermostat knob to maximum is not always the solution. In models Atlant with mechanical control (for example, MHM 1705 or MHM 2835), temperature control is associated with the operation of the compressor and the refrigerant circulation system. And in electronically controlled refrigerators (XM 6025, XM 4626), the cooling algorithm depends on sensors and software settings. We will look at both options, and also touch on typical reasons why a refrigerator may not freeze well - from a clogged condenser to a worn seal.
If you notice that the motor is running without stopping, and the temperature in the chambers does not drop, or vice versa - the compressor turns on too rarely, first check simple points: whether the door is closed correctly, whether the shelves are overloaded, whether there are heat sources nearby. Often the problem is solved without calling a technician.
1. Temperature control in mechanical Atlant models
In refrigerators Atlant with a mechanical thermostat (for example, series MHM or HM), the temperature is regulated by a rotary knob located inside the refrigerator compartment. Usually it has 7 positions: from 1 (warmest) to 7 (maximum cold). The optimal position for most conditions is 3-4.
To increase cooling, turn the knob clockwise one or two divisions. For example, if it was on 3, install it on 4-5. Important: after changing the settings, wait 6-8 hours - the compressor needs time to stabilize the temperature. Do not leave the regulator on 6-7 for a long time: this increases the load on the motor and can lead to icing of the evaporator.
- 🔄 Position 1-2: minimum cooling (suitable for winter or if the refrigerator is in a cool room).
- ❄️ Position 3-4: optimal mode for most conditions (+4...+5°C in the refrigerator compartment).
- ⚠️ Position 5-7: maximum cold (use temporarily, for example, to quickly cool a large volume of food).
In models with two compressors (for example, Atlant MHM 2832), the freezing and refrigerating chambers are adjusted separately. For the freezer, positions from -12°C to -24°Care usually provided. If you need enhanced cooling in the main compartment, and the temperature in the freezer is already low, check whether the flow of cold air is blocked (for example, due to ice on the back wall).
⚠️ Attention: In mechanical models Atlant when turning the knob to 6-7 the compressor can work without stopping, which will lead to icing of the evaporator and increased energy consumption. If after 12 hours the temperature has not dropped, the problem is not in the settings - diagnostics are required.
2. Setting up electronic models (display and buttons)
Refrigerators Atlant with electronic control (series XM, NM) allow you to more accurately control the temperature. The display shows the current values for the refrigerator and freezer compartments, and parameters can be changed using buttons +/– or touch keys. Standard factory settings:
- 🧊 Refrigerator:
+4°C. - ❄️ Freezer:
–18°C.
To make it colder:
- Press button
Setting(orMenudepending on the model). - Select section
Refrigerator compartment temperature(orFridge Temp). - Use the buttons
+/–set the value+2...+3°C. - Confirm the changes (in some models you need to press
OKor wait 5 seconds).
In models with the function Super Cool (for example Atlant XM 6021-080), you can activate the intensive cooling mode for 2-6 hours. To do this:
Press and hold the "Super Cool" button for 3 seconds.
until the indicator lights up.
Electronic refrigerators Atlant are often equipped with sensors that block the temperature from being set too low. If the display shows an error (for example, E1 or H), this may indicate a faulty sensor or compressor.

3. Checking the seal. doors: why the cold goes away
If the refrigerator Atlant works without stopping, but the temperature in the chamber does not drop, the first reason is damaged or dirty seal. The rubber around the perimeter of the door loses its elasticity over time, cracks or moves away from the body:
- Take a sheet of A4 paper.
- Place it between the seal and the refrigerator body.
- Close the door and try to pull it out sheet.
If the paper comes out without effort, the seal is faulty. Check it around the entire perimeter, especially in the corners.
Common causes of problems with the seal:
- 🧽 Pollution: fat, crumbs or sticky residues prevent a tight seal.
- 🔥 Deformation: from high temperatures (if the refrigerator is located next to the stove) or mechanical damage.
- 🕳️ Cracks: in older models, the rubber “shrinks”, forming gaps.
To restore the tightness:
- Clean the seal with warm water and soap, then wipe with ammonia (1 tablespoon per 1 liter of water).
- If the rubber comes off, carefully glue it with silicone sealant (for example, Moment Crystal).
- For a temporary solution, use a hairdryer: heat the seal in problem areas (temperature 50-60°C) so that it takes shape.
⚠️ Attention: If the seal is cracked or lost its shape, it needs to be replaced. For refrigerators Atlant the original ones are suitable. rubber gaskets (the article depends on the model, for example, for MHM 1840 — 54.010.01). Do not use non-original seals - they may not provide a tight fit.
How to remove the seal for replacement
1. Open the door and look for the mounting screws under the decorative panel (they may be hidden by plugs).
2. Carefully pry the seal with a screwdriver in one of the corners and pull it towards you - it rests on the grooves.
3. The new seal is inserted into the groove and secured with screws. Heat it with a hairdryer before installing for a better fit.
4. Cleaning the condenser: why the refrigerator does not cool
The condenser (radiator on the back wall of the refrigerator) removes the heat generated by the compressor. If it is clogged with dust, wool or cobwebs, heat exchange is disrupted and the refrigerator Atlant begins to freeze worse. In severe cases, the compressor overheats and turns off due to protection.
Signs of a clogged condenser:
- 🔥 The compressor runs for a long time (more than 20 minutes) and gets very hot.
- 📈 Energy consumption has increased (the counter spins faster).
- ❄️ Ice forms in the freezer, but it is warm in the refrigerator.
How to clean the condenser:
- Unplug the refrigerator and move it away from the wall (minimum distance - 50 cm).
- Remove the bottom protective panel (it is secured with latches or screws).
- Use a vacuum cleaner with a narrow attachment to remove dust between the radiator fins. For severe dirt, use a soft brush.
- Wipe the fins with a damp cloth, then dry.
In models Atlant with a system No Frost (for example, XM 4626-100) capacitor can be located on the side or bottom. If access to it is difficult, do not disassemble the case yourself - contact the service.
| Refrigerator model | Condenser location | Cleaning frequency |
|---|---|---|
| Atlant MXM 1705 | Back wall, bottom | 1 time every 6 months |
| Atlant XM 6025 | Back wall, along the entire height | 1 time every 3 months (due to No Frost) |
| Atlant MHM 2832 | Bottom, under the compressor | once a year (if there are no pets) |
⚠️ Attention: When cleaning the condenser, do not use metal brushes or sharp objects - they can damage the tubes with refrigerant. If you notice signs of corrosion or oil leakage, immediately turn off the refrigerator and call a technician.
5. Checking ventilation and loading of products
Even a working refrigerator Atlant will cool poorly if the air circulation inside the chambers is disrupted. Common mistakes:
- 🥦 Overloading the shelves: if the products are close together, cold air does not pass.
- 🧊 Blocking the ventilation holes: in models with No Frost (for example, XM 4626) on the back wall there are grates for circulation.
- 🔥 Hot foods: placing pots of soup or fried food increases the temperature in the chamber.
Loading rules:
- 📦 Place products so that there is 2-3 cm of free space between them.
- 🍖 Place meat and fish on the lower shelves (it’s colder there).
- 🥛 Dairy products and drinks - on the middle ones shelves.
- 🍎 Fruits and vegetables - in special boxes (there is high humidity).
In refrigerators Atlant with a system No Frost a fan distributes cold air throughout the chamber. If it is blocked (for example by a grocery bag), the temperature will rise. Check if something is interfering with its operation - usually the ventilation holes are located on the back wall of the refrigerator compartment.
6. Diagnosis of faults: when you need a specialist's help
If all of the above methods did not help, the problem may be in technical malfunction. Let's look at typical refrigerator breakdowns Atlant and their symptoms:
| Malfunction | Symptoms | Possible solution |
|---|---|---|
| Failure of the thermostat | The compressor does not turn on or runs without stopping | Replacement of the thermostat (part cost - from 800 ₽) |
| Leakage refrigerant | The freezer does not freeze, the compressor is hot | Finding the leak and refilling with freon (from 2500 ₽) |
| Clogged capillary tube | The refrigerator is weak cools, the condenser is cold | Purge the system or replace the tube (from 3000 ₽) |
| Faulty compressor | The motor hums, but does not start | Replacement of the compressor (from 4000 ₽) |
To diagnose some problems, disassembling the refrigerator is not required. For example, to check the thermostat:
- Disconnect the refrigerator from the network.
- Remove the thermostat protective casing (usually it is located next to the adjustment knob).
- Short the two wires going to the thermostat together (take a photo of the connection diagram first!).
- Turn on the refrigerator. If the compressor works, the thermostat is faulty.
⚠️ Attention: If a refrigerator Atlant with electronic control shows an errorE3orE4, this indicates a problem with the temperature sensors. Self-repair may lead to failure of the control board. In this case, contact an authorized service center.
7. Additional ways to improve cooling
If the refrigerator Atlant is working at maximum capacity, but the temperature is still above normal, try these methods:
- 🌡️ Use an external thermometer: place it on the middle shelf to accurately control the temperature. In mechanical models, the regulator scale is conditional.
- 🔌 Check the voltage in the network: if it is below 200V, the compressor does not develop full power. Use a stabilizer.
- ☀️ Move the refrigerator: if it is located next to a battery, stove or in direct sunlight, the heat load increases.
- 🧊 Defrost the refrigerator: in models without No Frost Ice on the evaporator impairs heat transfer. Complete defrosting takes 12-24 hours.
In Atlant refrigerators with one compressor (for example, MXM 1840), when the freezer operates intensively, the temperature in the refrigerator compartment can rise to +8...+10°C. This is normal if the freezer is cooled to -18°C. To balance the modes, set the refrigerator compartment control 1-2 notches higher than the freezer one.
For models with No Frost (for example, XM 4626) it is useful to clean the drainage hole in the refrigerator compartment every six months. It is located on the back wall and is often clogged with crumbs. For cleaning, use a cotton swab or a syringe with warm water.
Frequently asked questions about setting up Atlant refrigerators
❓ Why does the freezer freeze in the Atlant refrigerator, but the refrigerator compartment does not?
In models with one compressor, the cold first enters the freezer, and then - into the refrigerator compartment. If the freezer is working and the main compartment is warm, check:
- If the cold air supply channel is blocked (in models with No Frost).
- If the fan is working (in refrigerators with forced circulation).
- If the refrigerator compartment regulator is set to the minimum value.
If the problem persists, there may be a refrigerant leak in the refrigeration chamber circuit.
❓ What temperature should be in the Atlant refrigerator?
Optimal values:
- fridge compartment:
+2...+5°C. - Freezer compartment:
–18...–24°C. - Freshness zone (if any):
0...+1°C.
In mechanical models, the exact temperature can only be measured with a thermometer. In electronic models, it is displayed on the display.
❓ Is it possible to place the Atlant refrigerator on the balcony in winter?
No. At temperatures below +10°C:
- The oil in the compressor thickens, which leads to its wear.
- The thermostat may not work and the motor will not turn on.
- The seal loses its elasticity.
If the refrigerator was still standing in the cold, before turning it on, keep it for 12 hours at room temperature.
❓ Why does the Atlant refrigerator constantly work and does not turn off?
Possible reasons:
- High temperature in the room (more than 30°C).
- Malfunction of the thermostat or temperature sensor.
- Refrigerant leak (the compressor tries to compensate for the loss of cold).
- Dirty condenser.
First check the seal and ventilation, then call a technician for diagnostics.
❓ How to reset an Atlant refrigerator with electronic control?
To reset to factory settings:
- Press and hold the button
Setting(orMenu) for 10 seconds. - The display will show
rStorCLr. - Confirm reset button
OK.
After resetting, the temperature will be set to +4°C (refrigerator) and –18°C (freezer).
