How to increase the temperature in the Atlant refrigerator: instructions and tips

Refrigerator Atlant is one of the most popular brands in the post-Soviet space, but even with it problems sometimes arise. If you notice that the food is not cooling enough, condensation is forming on the walls, or the freezer is not freezing well, most likely the temperature in the unit is below normal. In this article, we will look at how to increase the temperature in a refrigerator Atlant of different models without resorting to the help of a technician.

The reasons for poor cooling can be different: from a banal error in the settings to serious malfunctions. We'll cover every possible option, from adjusting the thermostat to checking the seal and ventilation. You will also find out which models Atlant (for example, MHM 1708 or XM 4426) have special configuration features and what to do if standard methods do not help.

Important: before any manipulations, unplug the refrigerator for 10-15 minutes. This will reset possible temporary malfunctions in the operation of the electronic control unit (if your model has one).

1. Checking the current temperature settings

The first thing to do is make sure that the refrigerator correctly configured. In most models Atlant temperature adjustment is carried out by a mechanical thermostat (wheel with numbers) or an electronic panel (in new series, for example, Nova Frost).

For mechanical models (Atlant MHM 1705, XM 4026 and etc.):

• 🔢 The rotary wheel is usually located inside the fridge compartment on the right wall.
• 📉 The numbers indicate cooling level, not degrees: "1" - minimum cold, "7" - maximum.
• ❄️ For the freezer compartment there is a separate regulator (if the chambers are separate).

For electronic models (Atlant XM 6025, Nova Frost NF 120):

• 📱 Setting via touch panel or “+”/“–” buttons on the display.
• 🌡️ Temperature is displayed in degrees (optimally: +4…+5°C for the refrigerator compartment, –18°C for freezer).
• 🔄 Some models have a mode "Super Freeze" —its activation temporarily increases power.

If the regulator is already at maximum (“7” or –24°C), but the refrigerator still does not cool, there is a problem lies deeper. Go to the next section.

2. Diagnostics of the door seal

One of the most common reasons poor cooling is wear or contamination of the rubber seal. If the door does not close tightly, warm air gets inside and the compressor cannot cope with the load. It’s easy to check the seal:

Visually inspect for cracks and tears|

Pass a sheet of paper between the door and the body - if the sheet is easily pulled out, the seal is leaky|

Glue the rubber band soap solution and close the door - if bubbles appear, there are cracks|

Wipe the seal with alcohol to remove grease and dirt (they interfere with a tight fit)-->

If the seal is damaged, it can be restored:

• 🔥 Heat the deformed areas with a hairdryer (temperature 60–70°C) and shape it with your hands.
• 🧴 Apply silicone grease to extend service life.
• 🛠️ As a last resort, replace the elastic band (select according to the refrigerator model).

After restoring the seal, wait 2-3 hours and check the temperature. If the problem remains, move on.

3. Cleaning the condenser and ventilation

The condenser (grid on the back wall of the refrigerator) and the ventilation holes inside the chamber are often clogged with dust and wool. animals or ice. This leads to compressor overheating and poor cooling. How to clean:

1. Unplug the refrigerator.
2. Move it away from the wall (at least 50 cm for access).
3. Use a vacuum cleaner or brush to remove dust from the condenser (do not use water!).
4. Inside the chamber, check the ventilation holes (usually in the upper part of the back wall) - they should not be blocked by products.

In models with the system No Frost (Atlant Nova Frost) additionally check the evaporator (hidden behind the back panel of the freezer). If it is covered with ice, defrosting is required (see section 5).

4. Check the operation of the compressor and thermostat

If the previous steps did not help, the problem may be in compressor (does not pump freon) or thermostat (does not give a signal for cooling) You can check their operation yourself:

If the compressor does not turn on at all, check:

• 🔌 There is voltage in the socket (connect another device).
• 🔧 The fuse in the refrigerator plug (some models have it).
• ⚡ Wiring for damage.

What to do if the compressor hums, but does not freeze?

This is a sign of a freon leak or a clogged capillary tube. It is impossible to fix the problem yourself - you need a specialist with equipment to charge the refrigerant.

5. Defrosting the refrigerator (if there is ice)

In models without No Frost (for example, Atlant MHM 1708), ice on the back wall of the refrigerator compartment is normal, but its thickness should not exceed 5–7 mm. If the ice accumulates more, it interferes with heat transfer and reduces cooling efficiency.

How to defrost correctly:

1. Unplug the refrigerator.
2. Take out all the food and shelves.
3. Put a cloth under the bottom to collect water.
4. Leave the door open for 6-12 hours (depending on the amount of ice).
5. Do not use a hair dryer or sharp objects to speed up the process!
6. After defrosting, wipe the chamber with a dry cloth and turn on refrigerator.

In models with No Frost defrosting is required less often (once every 1-2 years), but if ice has accumulated on the evaporator, it also needs to be removed.

6. Checking temperature sensors (for electronic models)

In refrigerators Atlant electronically controlled (Nova Frost, XM 6025) sensors are responsible for correct operation. If they fail, the control unit receives incorrect data and incorrectly regulates the temperature.

Symptoms of sensor malfunction:

• 🌡️ The display shows incorrect temperature (for example, +10°C at real +20°C).
• ❄️ The compressor works without stopping or, on the contrary, almost does not turn on.
• 🔄 The “Super Freeze” mode does not turn off automatically.

You can check the sensor with a multimeter (if you have skills in working with equipment):

1. Disable refrigerator.
2. Remove the back panel in the refrigerator compartment (the sensor is usually located next to the evaporator).
3. Measure the resistance of the sensor at room temperature (norm: 4–6 kOhm).
4. If the values are very different, the sensor requires replacement.

7. When to call a technician: signs of serious damage

If you have tried everything. methods, but the temperature in the refrigerator Atlant still does not rise to normal, most likely the problem requires professional intervention Contact the service center if:

• 🔧 The compressor turns on for 1-2 seconds and immediately turns off (starter faulty). relay).
• 🧊 A “snow coat” more than 1 cm thick is formed on the back wall of the refrigerator compartment (freon leakage).
• 🔥 The compressor housing is heated to a temperature at which it is impossible to touch (interturn short circuit).
• 💡 An error flashes on the electronic panel (for example, E1, E2 —for decoding, see the instructions for the model).

In Atlant models with an inverter compressor (for example, Nova Frost NF 120), independent diagnostics of the electronics can cause damage to the control unit.

FAQ: Frequently asked questions about setting the temperature in Atlant

What temperature should be in the Atlant refrigerator?

Optimal values:

• Refrigerator compartment: +3…+5°C.
• Freezer compartment: –18°C (for long-term storage) or –12°C (for short-term storage).

In models with a freshness zone (for example, Atlant XM 4626), the temperature in the “zero” zone should be 0…+1°C.

Why does the Atlant refrigerator not freeze, but the light is on?

This is a classic sign of a problem with thermostat or compressor. The light is on because there is power, but the cooling signal is not received. First, check the thermostat (turn the regulator to maximum - if the compressor does not start, the thermostat does not start). faulty). If the thermostat is OK, the problem is in the compressor or start relay.

How long does it take for the Atlant refrigerator to reach temperature after defrosting?

Depending on the model and volume chambers:

• Small refrigerators (100–150 l): 1–2 hours.
• Medium (200–300 l): 3–4 hours.
• Large (350 l+) or with No Frost: up to 6 hours.

Do not load products immediately - wait, until the temperature stabilizes.

Is it possible to regulate the temperature in the freezer and refrigerator compartments separately?

Yes, but only in models with separate regulatorsFor example:

• V Atlant MHM 1708 —one wheel for the refrigerator compartment, the other for the freezer.
• V Nova Frost NF 120 —electronic control with separate settings for each zone.

In budget models (for example Atlant XM 4026), the adjustment is general - changing the temperature in one chamber will affect the other.

What to do if, after adjustment, the temperature either rises or falls?

This sign unstable operation of the thermostat or freon leakage. Also the cause may be:

• 🔌 Unstable voltage in the network (connect the refrigerator via stabilizer).
• 🧊 Clogged capillary tube (cleaning required by a specialist).
• 🌡️ Malfunction of the temperature sensor (in electronic models).

If the problem does not disappear, call a technician for diagnostics.
