Why the freezer in the Atlant refrigerator does not work: reasons and repair

Have you opened the freezer Atlantand there, instead of the usual cold, it’s warm, the food has begun to thaw, or is the compressor generally silent like a fish on ice? Don’t rush to panic and take your equipment to service. In 70% of cases, the problem is solved on its own in 10–30 minutes if the cause is correctly identified. This article will help you understand why the freezer stopped working, even if the refrigerator compartment is functioning normally.

We analyzed hundreds of reviews from owners Atlant (models MHM-1705, MX-2824, NM-4421 etc.), typical complaints from craftsmen and technical documentation of the plant. It turned out that most of the malfunctions were related to five key nodes: thermostat, No Frost system, compressor, electronics and freon leak. Below is a detailed analysis of each reason with photographs, diagrams and instructions for elimination.

1. Checking the obvious: power supply, settings and external factors

Before disassembling the refrigerator, exclude trivial reasons that are often overlooked:

• 🔌 Power: Make sure that the plug is tightly inserted into the socket (sometimes the contacts oxidize). Try connecting another device to this outlet - does it work? If not, the problem is in the wiring, not in the refrigerator.
• ❄️ Defrost mode: On models with No Frost check to see if the forced defrost button (usually indicated by a snowflake) is activated. In mechanical models (Atlant MXM-1635), the defrost timer may have worked - wait 1-2 hours.
• 🌡️ Temperature range: The regulator on the control panel (or inside the chamber) could have gone astray. The optimal position for the freezer is between 3 and 4 (in models with a digital scale).
• 🚪 Closing tightness: Check the sealing rubber - if it is torn or deformed, warm air gets inside and The freezer can't handle it. Carry out a test with a sheet of paper: it should be pressed tightly against the door.

If all of the above is in order, but the freezer still does not freeze, proceed to diagnosing the internal components. Pay special attention to models with the No Frost system - in 40% of cases the problem lies in the failure of the defrosting system, which leads to icing of the evaporator and blocking of air circulation.

2. Thermostat (thermostat): how to check and replace

The thermostat is the “brain” of the freezer, which controls the temperature and sends signals to the compressor. If it fails, the compressor either does not turn on at all or works without stopping (which is also dangerous). Signs of a broken thermostat:

• ❌ The compressor does not start, although the light inside the chamber is on.
• ⚡ The compressor runs continuously, but the freezer does not cool.
• 🔄 The temperature in the chamber jumps from -5°C to +10°C without visible reasons.

To check the thermostat, follow these steps:

1. Unplug the refrigerator and remove the thermostat protective cover (usually located inside the chamber, under the plastic panel).
2. Disconnect the wires from the thermostat (take a photo of their location!) and short them together. If the compressor starts after this, the thermostat is faulty.
3. Test the thermostat with a multimeter in resistance test mode. At room temperature, the resistance should be about 0 Ohm, when cooled (for example, with ice) it should approach infinity.

If the thermostat is faulty, it needs to be replaced. For models Atlant thermostats are suitable K-59 (for freezer) or TAM-133 (universal). Cost - from 500 to 1500 rubles. Replacement takes 15–20 minutes:

Turn off the power and defrost the chamber|

Remove the temperature control knob|

Unscrew the fastening screws and remove the thermostat|

Connect the new thermostat according to the diagram (photo!)|

Install and check operation-->

⚠️ Attention: In models with electronic control (Atlant NM-6021, NM-4626) instead of mechanical The thermostat is used temperature sensor and a control board. Here the diagnosis is more complicated - you will need to check the resistance of the sensor (norm: 5–7 kOhm at +20°C).

3. Problems with the No Frost system: evaporator icing

If your Atlant equipped with a system No Frost (models MHN-1840, MHN-2831 etc.), then the most likely cause of freezer failure is evaporator icing. This occurs due to a malfunction of one of three elements:

To fix the problem:

1. Defrost the refrigerator for 12-24 hours (completely!).
2. Remove the back panel of the freezer (unscrew the screws).
3. If the ice on the evaporator has not melted, use a hairdryer (only at minimum power!).
4. Ring the heating element and sensor. Replace the faulty parts.

Critical error: if after defrosting ice forms again within 1-2 days, the problem is a freon leak or clogging capillary tube. Here you will need the help of a specialist.

What will happen if you ignore icing of the evaporator?

Without timely repair, the ice will completely block the air circulation, which will lead to:

1) Overheating of the compressor and its failure (replacement cost - from 5,000 rubles).

2) Corrosion of the evaporator and leakage of freon (repair will cost 8,000–12,000 rubles).

3) Spoilage of products due to unstable temperature.

4. Compressor: why it doesn’t start or overheats

The compressor is the “heart” of the refrigerator. If it doesn't work, the freezer won't cool. The reasons may be different:

• 🔋 The starting relay has burned out — the compressor hums, but does not start. The relay costs 800–1500 rubles, you can replace it yourself.
• 🔥 Interturn short circuit in the winding —the compressor heats up, but does not pump freon. Replacement is required (the price of a new one is from 4,000 rubles).
• ⚡ Breakthrough to the housing —if you touch the refrigerator with an electric shock, immediately disconnect it from the network!
• ❄️ Motor jamming —the compressor does not make sounds, but is hot. Often occurs due to overloads.

How to diagnose a compressor:

1. Turn off the refrigerator and remove the back cover (bottom).
2. Test the compressor windings with a multimeter:
   • Resistance between C (common) and S (starting) — 20–30 Ohm.
   • Resistance between C and R (working) — 10–15 Ohm.
   • The resistance between S and R is the sum of the two previous values.

If the resistance is equal 0 or ∞ —open or short circuit. If the resistance between the case and the contacts is not ∞ - breakdown.

⚠️ Attention: If the compressor is overheated (the case is hot, but does not work), do not turn on the refrigerator for at least 2 hours. Restarting may lead to permanent failure.

5. Freon leak: how to recognize and what to do

Freon is a refrigerant that circulates through the system and provides cooling. If it leaks, the freezer stops freezing and the compressor runs idle. Signs of a leak:

• ❄️ The compressor works without stopping, but there is no cooling.
• 🔍 Oil stains are visible on the back wall of the refrigerator (freon leaks along with the oil).
• 💨 You can hear the leak at the place of the leak (usually on pipes or soldering areas). light hissing.

It is impossible to eliminate a freon leak on your own - you will need to:

1. Find the location of the leak (using a leak detector or soap solution).
2. Repair the damage (solder the tube or replace the evaporator).
3. Evacuate the system and fill with new freon (usually R-134a or R-600a for modern models Atlant).

Repair cost: from 3000 to 8000 rubles (depending on the complexity of the leak). If a leak occurred in the evaporator (for example, due to corrosion), it will have to be replaced completely (price - from 5,000 rubles).

6. repair

In modern models Atlant (for example, NM-6021-080, NM-4626-100) the electronic board is responsible for the operation of the freezer. If it fails, the following symptoms are possible:

• 📛 An error flashes on the display (for example, E1, E2, E5 —the decoding is in the instructions).
• 🔄 The freezer turns on and off for no reason.
• 🖥️ The display does not respond to button presses.

Causes of board failure:

• ⚡ Power surges in the network (a common problem in rural areas).
• 💧 Moisture ingress (for example, during defrosting).
• 🔥 Overheating due to poor ventilation (if the refrigerator is close to the wall).

What you can do yourself:

1. Reset the settings to factory settings: turn off the refrigerator for 5 minutes, then turn on.
2. Check the fuse on the board (if it is blown, replace it with a similar one).
3. Inspect the board for blackened elements or swollen capacitors.

If the board is damaged, it can be:

• Repaired (cost - 2000–4000 rubles).
• Replace with a new one (price - 5000–9000 rubles).

⚠️ Attention: If you do not understand electronics, do not try to solder the board yourself. Errors can lead to a short circuit or fire.

7. Capillary tube clogged: how to clean the system

The capillary tube is a thin channel through which freon enters the evaporator. If it becomes clogged (for example, due to moisture or oil), freon does not circulate and the freezer does not cool. Signs of a blockage:

• 🔄 The compressor works, but the condenser (grid at the back) does not heat up.
• ❄️ The freezer does not freeze, but the refrigerator compartment works fine.
• 💨 The fan in the freezer blows, but there is no air cold.

To clean the capillary tube you will need:

1. Pump out the freon from the system.
2. Disconnect the capillary tube from the evaporator.
3. Blow it with nitrogen under pressure 15–20 atm.
4. If the blockage does not clear, replace the tube.
5. Evacuate the system and fill with new freon.

Repair cost: from 4000 to 7000 rubles It is not recommended to clean the tube yourself. - without special equipment, you can damage the system.

8. When to call a technician: 5 signs of a serious breakdown

Some breakdowns require professional intervention Contact the service center if:

• 🔥 The compressor gets very hot and turns off after 5-10 minutes of operation.
• ⚡ Voltage has appeared on the refrigerator body (electric shock).
• 💨 There is a sharp chemical smell coming from under the refrigerator (freon leakage).
• 🔊 The compressor hums, but does not start (perhaps the motor is jammed).
• 📛 The display shows an error that cannot be reset (E3, E4, E6 - usually indicates a faulty board or sensors).

Average cost of repairs in the service:

When selected service, please note:

• 📄 Availability of a warranty on work (minimum 6 months).
• 🔧 Use of original spare parts (ask for certificates).
• ⭐ Reviews on Yandex.Maps or 2GIS (especially about repair times).

⚠️ Attention: If your refrigerator Atlant is under warranty (usually 1-3 years), do not disassemble it yourself. This will void the warranty. Contact an authorized service center (the list is on the website Atlant).

FAQ: Frequently asked questions about the non-working freezer in the Atlant refrigerator

The freezer does not freeze, but the light inside is on. What's the matter?

Most likely, the problem is thermostat or compressorCheck:

1. Compressor sound - if it does not hum, check the thermostat (see section 2).
2. If the compressor works, but does not cool, it is possible freon leakage or clogging of the capillary tube.

In models with No Frost also check Defrost heating element - if it burns out, the evaporator will freeze up and the freezer will stop working.

Refrigerator Atlant MHM-1705: the freezer turns off after 5 minutes What to do?

This is a typical sign:

• Overheating of the compressor (possibly due to a dirty capacitor or a faulty relay).
• Clogged capillary tube (freon does not circulate, the compressor runs idle and is switched off by protection).
• Malfunction of the control board (in models with an electronic unit).

Turn off the refrigerator for 2 hours, then try to start it again. If the problem persists, call a technician.

After defrosting, the freezer does not turn on. What to check?

Probable reasons:

1. Moisture got on the control board (if defrosted with a hairdryer or warm water).
2. The defrost heating element has burned out (in models c No Frost).
3. The fan is jammed (check if it spins when turned on).

Try to dry the refrigerator for a day with the door open. If that doesn’t help, diagnose the board and. Heating element.

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

Theoretically, yes, but in practice it is dangerous and ineffective without experience. To fill freon you need:

• Special equipment (gauge manifold, vacuum pump).
• Knowledge of the type of freon (for Atlant usually R-134a or R-600a).
• Ability to solder with copper-phosphorus solder (to eliminate leaks).

Errors during refueling can lead to damage to the compressor or explosion of a freon cylinder. It is better to entrust this to professionals.

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

The cost depends on the breakdown:

• Replacement of the thermostat — 1000–2000 rubles. (with a spare part).
• Repair No Frost (heating element, sensor, timer) - 2000–4000 rubles.
• Replacement of the compressor — 5000–8000 rubles.
• Elimination of freon leaks — 3000–10000 rub. (depending on complexity).

In regions, prices may differ by 15–20%. The exact cost will be announced after diagnosis.
