The refrigerator compartment in the Atlant refrigerator is not cold - what to do?

Did you open the refrigerator Atlantand instead of the usual chill, you felt room temperature? The refrigerator compartment has stopped freezing, the food is spoiling, and the freezer is working as if nothing had happened - or, on the contrary, is it also malfunctioning? This problem is familiar to many owners of Belarusian refrigerators, and its reasons can vary from a banal settings failure to a serious compressor breakdown.

In this article we will look at why the refrigerator compartment in all possible reasons, according to which the refrigerator compartment in Atlanta may not cool - from a clogged drainage until the electronic module fails. You will learn how to diagnose a malfunction yourself, what manipulations can be done without calling a technician, and in which cases, doing the repair yourself will only worsen the situation. We will pay special attention to models Atlant XM, MHM and NRM, where the problem occurs most often.

Before starting repairs, check the obvious: whether the lights were turned off, whether the installation location of the refrigerator was changed, whether it was loaded with food to capacity. Sometimes the reason lies in the little things that even experienced users miss.

1. Temperature violation: checking the settings

The first thing you need to do is make sure that the refrigerator correctly configured. In models Atlant with mechanical control (for example, Atlant XM 4021-000), the temperature is adjusted using a rotary switch, where the numbers 1–7 correspond to the cooling level. In electronic models (series NRM), configuration is carried out through the control panel with a display.

If the refrigerator compartment is not cold, but the freezer is working, check:

  • 🔹 Position of the temperature regulator —it could have gone astray when cleaning or rearranging. The optimal value for the refrigerator compartment: 3–4 (in mechanical models).
  • 🔹 Vacation mode - if it is activated (the indicator is on Vacation), the refrigerator compartment turns off, and the freezer continues to operate.
  • 🔹 Super Freeze function —in some models, when it is turned on, the main compressor switches to the freezer, temporarily “forgetting” about the refrigerator compartment.
⚠️ Attention: In refrigerators Atlant s system No Frost (for example, Atlant MXM 2835-90) failure of the settings can lead to icing of the evaporator. If after resetting the settings the problem does not disappear, do not try to defrost the unit with a hairdryer - this may damage the board!

How to reset the settings to factory:

  1. Disconnect the refrigerator from the network for 10-15 minutes.
  2. Turn it back on and set the temperature regulator to position 3.
  3. If the model is electronically controlled, press the button Super (or Mode) on 5–7 seconds before the sound signal.

2. Problems with the door seal: diagnosis and repair

A worn or dirty seal is one of the most common reasons why the refrigerator compartment does not cool well. The rubber loses its elasticity, gaps appear, and warm air penetrates inside, causing the compressor to wear out. As a result, the temperature in the chamber rises, and condensation or ice forms on the back wall. Atlanta doesn't cool well. The rubber loses its elasticity, gaps appear, and warm air penetrates inside, causing the compressor to wear out. As a result, the temperature in the chamber rises, and condensation or ice forms on the back wall.

How to check the seal:

  • 🔍 Visual inspection —look for cracks, tears or deformations. The corners of the door are especially vulnerable.
  • 📏 Test with a sheet of paper - close the door, holding the sheet between the seal and the body. If the sheet is easily pulled out, the seal is broken.
  • 💡 Check for light —in a dark room, shine a flashlight inside a closed refrigerator. If light is visible from the outside, the seal allows air to pass through.

If the seal is damaged, it can be restored or replaced:

  • 🛠️ Small cracks - treat with silicone grease (for example, WD-40 Specialist).
  • 🔥 Deformation - immerse the seal in hot water (not boiling water!) for 5-10 minutes, then shape it and secure the door with tape for a day.
  • 🔄 Full replacement - for models Atlant suitable seals marked A-40 (for single-chamber) or A-60 (for double-chamber). Average price - 1,200–2,500 ₽.

3. Clogged drain hole: why water accumulates in the refrigerator

If the refrigerator compartment is not cold, but ice forms on the back wall, and water accumulates under the vegetable drawers, there is a 90% chance that the drainage channel is clogged. data-i="136">Atlant drainage channel. In models Atlant with drip defrosting system (Atlant XM 4426-000, Atlant XM 6021-031) condensate flows down the back wall into the drainage hole, and from there into the container on the compressor. If the hole is clogged, the water freezes, forming an ice plug that blocks circulation. air.

How to clean the drainage:

  1. Unplug the refrigerator and defrost it for 10-12 hours.
  2. Find the drainage hole at the bottom of the back wall (in some models it is hidden by a plastic plug).
  3. Take a syringe with warm water or a wire with a diameter of 2-3 mm and carefully clean the channel. Do not use sharp objects - you can damage the plastic!
  4. Rinse the hole with a soda solution (1 tbsp per 200 ml of water) to remove mold and grease.
⚠️ Attention: If after cleaning the drainage the refrigerator still does not cool and the compressor runs without stopping, the problem may be in clogging of the capillary tube (see section 5). equipment!

In models with No Frost (for example, Atlant MHM 1708-01) the drainage hole is located behind the rear panel of the freezer. To access it, you will need to remove it. cover - this is more difficult than in drip systems, so if you are not confident in your abilities, it is better to call a specialist.

4. Malfunction of the thermostat or temperature sensor

Thermostat (in mechanical models) or temperature sensor (in electronic) - this is the “brain” of the refrigerator, which signals the compressor when to turn on or off. If the thermostat is broken, the compressor either works continuously or does not turn on at all. As a result, the refrigerator compartment does not cool, and the freezer can either freeze or thaw.

Signs of a thermostat malfunction:

  • 🔴 The compressor does not turn off or, on the contrary, is silent.
  • 🌡️ The temperature in the refrigerator compartment does not correspond to the set one (for example, it shows +8°C at setting +4°C).
  • 🔊 Clicks inside the case when turning the temperature regulator (in mechanical models).

How to check the thermostat:

  1. Disconnect the refrigerator from the network.
  2. Remove the thermostat protective cover (in models Atlant XM It is located inside the chamber, next to the lamp).
  3. Check the contacts with a tester in dialing mode:
    • At room temperature, the contacts 3 and 4 should be closed.
    • If you place the thermostat in ice, the contacts 3 and 4 should open.

If the thermostat does not respond to temperature changes, it must be replaced. models Atlant suitable thermostats K-59 (for single-chamber) or TAM-133 (for two-chamber). Average cost - 800–1,500 ₽.

How to temporarily bypass a faulty thermostat?

If the thermostat is broken and there is no way to replace it right away, you can connect the compressor directly, bypassing the thermostat. To do this:

1. Disconnect the refrigerator from the network.

2. Find the wires going from the thermostat to the compressor (usually brown and black).

3. Connect them together through the terminal (without twisting!).

⚠️ Attention: In this mode, the compressor will work constantly, which will lead to its overheating. Use only as a temporary solution!

5. Freon leakage or clogged capillary tube

If the refrigerator compartment does not cool, and the freezer works poorly or does not freeze at all, the problem may lie in refrigerant (freon) leakage or clogged capillary tube. This is one of the most serious malfunctions that requires professional repair.

Causes of leakage freon:

  • 🔧 Mechanical damage to the circuit (for example, during transportation or careless defrosting).
  • 🕳️ Corrosion of tubes (more common in older models Atlant with an aluminum circuit).
  • 🔥 Overheating of the compressor due to prolonged operation without shutting down.

Signs of a leak:

  • 🔊 The compressor works, but does not cool (or cools very little).
  • 🧊 The condenser (grid on the back wall) remains cold.
  • 💨 Frost appears in the freezer, but the temperature does not drop below 0°C.

Clogged capillary tube usually occurs due to moisture entering the system or oil decomposition. In this case, the compressor hums louder than usual, but does not produce cold. You can only diagnose a blockage using a pressure gauge - it is impossible to do this yourself.

⚠️ Attention: If you suspect a freon leak, do not turn on the refrigerator until repaired this can lead to failure of the compressor Freon in modern ones. models Atlant (for example, R600a) is fireproof, but its leak requires refueling the system by a specialist.
Symptom Probable cause Can I fix it myself?
The compressor runs non-stop, but does not cool Freon leak or clogged capillary tube ❌ No
The refrigerator compartment is warm, the freezer is working Thermostat or fan malfunction No Frost ✅ Yes (replace the thermostat)
On the back wall ice, water under the drawers Drain hole clogged ✅ Yes
The compressor does not turn on, the light inside is on Problems with the start relay or control board ⚠️ Partially (relay check)

6. Failure of the fan or No Frost system

In refrigerators Atlant with a system No Frost (for example, Atlant MHM 2808-60) The fan is responsible for air circulation. If it breaks, the cold stops flowing into the refrigerator compartment, and the freezer can continue to work (but not always). Reasons for fan failure:

  • 🍂 Freezing of the blades. due to icing of the evaporator.
  • 🔌 Fan motor malfunction (bearing wear, winding breakage).
  • 🔌 Power problems (fuse blown or contacts oxidized).

How to check the fan:

  1. Unplug the refrigerator and defrost it for 12 hours.
  2. Remove the back panel of the freezer (in most models Atlant it is secured with latches or screws).
  3. Try turning fan blades by hand - they should rotate easily, without squeaking.
  4. Connect the refrigerator to the network and listen - if the fan does not start, but voltage is supplied to it (checked by a tester), it means it has burned out.

If the fan is working, but the refrigerator compartment still does not cool, the problem may be in defrost heater or No Frost timer. These parts are responsible for automatic defrosting of the evaporator. When they break, the ice blocks the air circulation and the temperature in the chamber rises.

7. Malfunction of the compressor or start relay

Compressor - this is the “heart” of the refrigerator, and if it fails, the refrigerator compartment stops cooling. overheating or mechanical damage can cause them to fail ahead of schedule. Atlant compressors are used Danfoss or Secop (previously Embraco), which, if properly used, last 10–15 years. However, voltage surges, overheating or mechanical damage can cause them to fail ahead of schedule.

Signs of a compressor malfunction:

  • 🔇 The compressor does not turn on (no characteristic hum).
  • 🔥 The compressor housing gets very hot (above 90°C).
  • 💥 Protection is triggered (the refrigerator turns off a few seconds after starting).

Often the problem lies not in the compressor itself, but in start relay - a small box attached to the compressor. The relay is responsible for starting the motor, and if it burns out, the compressor will not work. You can check the relay as follows:

  1. Disconnect the refrigerator from the network.
  2. Remove the relay (it is attached with latches or screws).
  3. Shake it - if you hear it knocking, it means the contacts have come loose or burned out.
  4. Ring the contacts with a tester 1 and 2 (resistance should be 20–40 Ohm).

If the relay is faulty, it can be replaced with a new one (cost: 500–1,200 rubles). If the problem is in the compressor, its repair or replacement will cost 5,000–10,000 rubles, which is often comparable to the cost of a new refrigerator.

8. Problems with the electronic control module

In modern models Atlant with electronic control (series NRM, MHM) are responsible for the operation of all systems. If it fails, the refrigerator may behave unpredictably: the refrigerator compartment does not cool, the freezer operates jerkily, the display shows errors or does not turn on at all. control board. If it fails, the refrigerator may behave unpredictably: the refrigerator compartment does not cool, the freezer operates jerkily, the display shows errors or does not turn on at all.

Causes of board failure:

  • ⚡ Power surges in the network.
  • 💦 Ingress of moisture (for example, during defrosting).
  • 🔥 Overheating due to poor ventilation (the refrigerator is close to the wall).

Signs of a board malfunction:

  • 📛 Errors appear on the display (for example, E1, E2, E4).
  • 🔄 The refrigerator turns on/off spontaneously.
  • 🌡️ The temperature in the chambers does not correspond to the set temperature.

Independent repair of the board is possible only if you understand electronics. In most cases it is required flashing or replacement module. Average cost of a new board for Atlant — 3 000–6 000 ₽.

If the refrigerator is under warranty, do not try to repair the board yourself - this will lead to loss of warranty. Contact the service center Atlant (a list of official partners can be found on the manufacturer's website).

⚠️ Attention: Details of electronic boards in refrigerators Atlant may differ even within the same model. Before ordering a spare part, check its article number with the sticker on the back wall of the refrigerator or with a photo of the old board.

FAQ: Frequently asked questions about malfunctions of Atlant refrigerators

The refrigerator compartment does not cool, and the freezer works fine. What is the reason?

This is a typical symptom thermostat malfunction (in mechanical models) or No Frost fan (in systems with forced air circulation). Also, the cause may be clogged drain holes or freon leak in the refrigeration chamber circuit (if the freezer and refrigerator compartment have separate evaporators).

First, check the temperature settings, door seal and clean the drainage. If this does not help, call a technician to diagnose the thermostat or cooling system.

The Atlant refrigerator hums, but does not cool. What to do?

If the compressor is humming, but there is no cold, the following problems are possible:

  • 🔹 Clogged capillary tube —the compressor is working, but freon is not circulating.
  • 🔹 Refrigerant leak —the compressor is trying to bring in cold, but to no avail.
  • 🔹 Malfunction of the start relay —the compressor cannot start at full capacity.

You can check the relay yourself (see section 7). If the problem is not there, you will need the help of a specialist.

After defrosting, the Atlant refrigerator does not cool. Why?

Most often this is due to:

  • 🔹 Moisture getting on the electronic board (if defrosting was carried out incorrectly).
  • 🔹 Fan freezing No Frost —if you do not wait until complete defrosting, ice can block the blades.
  • 🔹 Settings failure - after disconnecting from the network, some models reset the settings.

Disconnect the refrigerator for 24 hours to dry completely, then turn it on and check the settings. If the problem persists, contact the service.

Is it possible to fill the Atlant refrigerator with freon yourself?

Noif you do not have special equipment and experience. Freon refilling requires:

  • 🔹 Vacuum pump for pumping air out of the system.
  • 🔹 Manometric manifold for pressure control.
  • 🔹 Knowledge about the types of refrigerants (in Atlant is used R600a or R134a).

Incorrect filling can lead to compressor explosion or poisoning (freon R600a flammable!). Contact the professionals.

How much does it cost to repair an Atlant refrigerator if the chamber does not cool?

The cost depends on the reason breakdowns:

Malfunction Repair cost (₽)
Replacing the seal 1 200–2 500
Cleaning the drainage 800–1 500
Replacing the thermostat 1 500–3 000
Repair of the control board 3 000–6 000
Freon refill + leak repair 4 000–8 000

Prices are indicated without taking into account the cost of spare parts. In the regions, repairs may cost 20–30% more.
