Disconnecting the freezer in a two-chamber Atlant refrigerator: instructions with photos and nuances

Two-chamber refrigerators Atlant are known for their reliability, but sometimes situations arise when the freezer compartment needs to be temporarily or permanently turned off. For example, if you are leaving for a long time and want to save energy, or the freezer is out of order and repairs are being postponed. Unlike single-chamber models, where turning off the compressor stops the operation of the entire unit, in double-chamber refrigerators with two cooling circuits you can deactivate only the freezer section, leaving the main compartment to function.

However, the process of turning off the freezer in Atlant has its own characteristics depending on the model, year of manufacture and type of control system (mechanical or electronic). In this article we will look at all possible methods - from simply turning the knob to disconnecting the sensors in models with No Frost. You will also learn what consequences a long shutdown of the freezer can have and how to properly prepare the refrigerator for this operating mode.

Before you begin manipulations, make sure that your model supports separate shutdown of the chambers. This function is not available in all series Atlant —for example, in budget models with one compressor (Atlant MXM 1705-80, Atlant XM 4021-000), the freezer cannot be turned off without completely turning off the refrigerator. At the same time, in two-compressor versions (Atlant MXM 2835-90, Atlant XM 6025-031) or models with a system Full No Frost this is easier to do.

1. How to determine whether you can turn off the freezer in your model Atlant

The first step is to find out whether your refrigerator supports separate shutdown of chambers. This depends on three key factors:

• 🔧 Number of compressors: In two-compressor models (Atlant MXM 2835-90, Atlant XM 6321-100), each compressor is responsible for its own chamber, so the freezer can be turned off independently. In single-compressor units - only together with the refrigeration compartment.
• 📟 Type of control system: Electronic panels (with display) often have the option Holiday Mode or Fridge Only. Mechanical regulators usually only allow you to set the temperature to a minimum.
• ❄️ Defrosting system: In models with No Frost turning off the freezer may require additional actions (for example, disconnecting the fan). In drip systems, the process is simpler.

To accurately identify your model, look at nameplate (metal plate) inside the refrigerator compartment or on the back wall. It contains full markings, for example: Atlant XM 6025-031 N. The first numbers after the letters indicate the series, and the last ones indicate the modification. If the plate is worn out, check the documentation or find the model by serial number in official catalog.

⚠️ Attention: If your refrigerator was manufactured before 2010, even if there are two compressors, the control system may not support separate shutdown. In this case, an attempt to turn off the freezer through the regulator will stop the entire refrigerator.

2. Turning off the freezer in refrigerators Atlant with mechanical control

Mechanical temperature controllers are the most common type of control in budget and mid-budget models Atlant. They are rotary knobs (usually two: one for the refrigerator, the second for the freezer) with gradation from 0 (off) to 7 (maximum cold). To turn off the freezer:

1. Locate the freezer control - it is usually located inside the freezer compartment or on the top panel of the refrigerator (depending on the model).
2. Turn the knob counterclockwise until it stops at the mark 0 or OFF.
3. Wait until the freezer compressor stops working (this will take 5-10 minutes). You will hear the refrigerator stop humming.

In some models (for example, Atlant XM 6025-031), the mechanical freezer regulator may be hidden under a decorative panel. To get to it:

• 🔨 Carefully pry the panel with a flat screwdriver (usually it is secured with latches).
• 🔧 Under the panel you will see a regulator knob - turn it to position OFF.
• 🔒 Secure the panel back, making sure that the latches are in place.

Important: In single-compressor models (Atlant MHM 1705-80), the mechanical freezer regulator actually controls damper, blocking the flow of cold air. When you turn to 0 the freezer will stop cooling, but the compressor will continue to work on the refrigerator compartment. However, in some cases this can lead to overheating compressor due to load balance imbalance —monitor the temperature in the main compartment.

3. Disabling the freezer compartment in models with electronic control

Refrigerators Atlant with an electronic panel (for example, Atlant XM 6025-031 N, Atlant MHM 1842-90) offer more customization options. Here the freezer can be turned off in two ways: through Vacation mode (Holiday Mode) or Manual shutdown in the menu. Let's consider both options.

Method 1: Activating the mode Holiday Mode

This mode is intended for long absence of owners. It maintains the temperature in the refrigerator compartment at +12...+15°C (enough to prevent mold), and completely turns off the freezer. To activate it:

1. Press the button Menu (or Set) on the electronic panel.
2. Use the buttons ↑/↓ find the item Holiday Mode (in some models - Vacation).
3. Confirm the selection by pressing OK or holding Set for 3 seconds.
4. Wait until the mode indicator appears on the display (usually the 🏖️ or HOL).

Features of the mode:

• ⏳ Activation time: 5–10 minutes (the freezer compressor does not stop instantly).
• 🔄 Automatic shutdown: after 2 weeks the refrigerator will return to normal mode (in models after 2018).
• ⚡ Energy savings: up to 40% compared to normal mode.

Method 2: Manually turning off the freezer through the menu

If there is no mode Holiday Mode you can turn off the freezer manually:

1. Press the button Freezer (or Fridge/Freezer) for 5 seconds until the freezer indicator flashes.
2. Use the buttons ↑/↓ set the temperature to 0°C or select item Off.
3. Confirm your choice with the button OK. The freezer indicator (🏔️ or snowflake ❄️) should go off on the display.

In models with touch controls (for example, Atlant XM 4426-100 ND), the path may be different:

Settings → Operating modes → Freezer → Turn off

⚠️ Attention: In refrigerators Atlant with a system No Frost when manually turning off the freezer, the fan can continue to operate for 1-2 hours for ventilation. This is normal and does not indicate a malfunction.

What to do if, after turning off, the freezer continues to freeze?

If after all the manipulations the freezer does not turn off, check:

1. Temperature sensor — in models with No Frost it may be shorted (replacement required).

2. Control board — firmware failure is possible (reset to factory settings is required).

3. Mechanical damper —in single-compressor models it may jam in the open position.

In these cases, the intervention of a specialist will be required. Independent repair of the board or sensors without experience is fraught compressor failure due to incorrect voltage supply.

4. Disabling the freezer in refrigerators with a system No Frost

Models Atlant with technology No Frost (for example, Atlant XM 4426-100 ND, Atlant MXM 2842-97) require a special approach. Here, the freezer is cooled by circulating cold air from the evaporator, so simply turning off the compressor may not work. You will need:

1. Turn off the power supply to the freezer through the regulator (as described above).
2. Forcibly stop the fan No Frost:
   • Remove the back panel of the freezer (by unscrewing 4–6 screws).
   • Locate the fan power connector (usually a white or black block with 2-3 wires).
   • Carefully disconnect the connector. The fan will stop working and the freezer will begin to defrost.

Close the cold air damper (if equipped). In some models, it is located in the upper part of the freezer and is closed manually.

Important: After the fan is turned off No Frost the refrigerator compartment may begin to cool worse, since some of the cold air stops circulating. Monitor the temperature in the main compartment using a thermometer.

If you plan to leave the freezer unplugged for a long time, it is recommended:

• 🧊 Completely defrost the freezer and dry it (to avoid mold).
• 🧽 Rinse the internal surfaces with a soda solution (1 tablespoon per 1 liter of water).
• 🚪 Leave the freezer door ajar (for example, placing a wooden block) for ventilation.

5. Possible problems and their solutions

When turning off the freezer compartment in refrigerators Atlant users often encounter typical problems. Let's look at the most common of them and how to eliminate them.

If, after turning off the freezer, the refrigerator begins to make unusual sounds (for example, hissing or clicking), this may indicate:

• 🔥 Overheating of the compressor —check is air access to the rear wall blocked?
• ⚡ Short circuit in the fan circuit - disconnect the refrigerator from the mains and check the wires.
• ❄️ Icing of the evaporator - defrost the refrigerator completely (at least 12 hours).

⚠️ Attention: If, after turning off the freezer, the refrigerator compartment begins to heat up (temperature above +10°C), immediately return the freezer to operating mode. In single-compressor models Atlant long-term operation without load on the freezer compartment can lead to compressor breakdown due to pressure imbalance in the system.

6. How to properly turn the freezer back on

If you have temporarily turned off the freezer, before turning it back on you need to follow several steps to avoid breakdowns:

1. Defrost the freezer completely (if it has been turned off for more than 2 days). Frost and ice can damage the evaporator when restarting.
2. Dry the chamber —wipe the walls with a dry cloth and leave the door open for 1-2 hours.
3. Check the drainage hole (at the bottom of the freezer) - it should not be clogged with ice or debris.
4. Turn on the freezer in minimum cooling mode (set the regulator to 1–2) and let it run for 2-3 hours before loading food.

For models with electronic control:

Settings → Freezer → Turn on → Set temperature -12°C

If after turning on the freezer does not cools:

• 🔌 Check whether the freezer compressor is connected to the network (in two-compressor models).
• ⏱️ Wait 6-12 hours - the first cooling after defrosting takes longer.
• 📞 If the freezer does not freeze after day, call a technician - there may be a freon leak or a compressor breakdown.

7. Common mistakes and how to avoid them

Many users make mistakes when turning off the freezer, which leads to breakdowns or ineffective operation of the refrigerator. Here are the most common of them:

• ❌ Disconnecting the refrigerator from the network without first defrosting —this can cause icing of the evaporator when turned on again.
• ❌ Using sharp objects to remove ice —it is so easy to damage the evaporator tubes, which will lead to freon leakage.
• ❌ Closing the ventilation holes in refrigerators No Frost - this disrupts air circulation and leads to overheating of the compressor.
• ❌ Long-term storage of a refrigerator with the freezer turned off in a damp room - this provokes corrosion of metal parts.

To avoid problems:

• 📋 Keep log shutdowns - write down the dates and reasons so as not to forget to turn the freezer back on.
• 🌡️ Use external thermometer to control the temperature in the refrigerator compartment.
• 🔧 Check regularly sealing rubber bands on the door freezers - they can dry out and crack without use.

⚠️ Attention: If you turn off the freezer because it is broken (for example, the compressor does not start or the freezer does not freeze), do not leave the refrigerator in this condition for a long time. In single-compressor models Atlant this can lead to refrigerator compartment overload failure of the only compressor.

Frequently asked questions

Is it possible to turn off the freezer in a refrigerator Atlant with one compressor?

In most single-compressor models (Atlant MXM 1705-80, Atlant XM 4021-000) you cannot completely turn off the freezer - the compressor works on both chambers. However, you can minimize its cooling by setting the freezer control to 0 and closing the damper (if there is one). In this case, the refrigeration chamber will operate normally, but the compressor may wear out faster due to load imbalance.

How much electricity can be saved by turning off freezer?

Savings depend on the model and operating conditions:

• In two-compressor refrigerators - up to 40–50% (freezing compressor consumes ~300–400 W/day).
• V single-compressor - up to 15–20% (the compressor still works, but turns on less often).
• In mode Holiday Mode —up to 30% (due to an increase in the temperature in the refrigerator compartment).

For an accurate calculation, use wattmeter or check the meter readings before and after shutdown.

What will happen if you leave it for a long time freezer turned off?

Long-term shutdown of the freezer (more than 1 month) can lead to:

• 🦠 Appearance mold on seals and walls (especially if the chamber is not dried).
• 🔋 Drying of grease in fan bearings (in models No Frost).
• 🧊 Corrosion metal parts due to condensation.
• 🔧 Stuck dampers (in single-compressor models).

To avoid these problems, turn on the freezer for 1-2 hours every 2 weeks for prevention.

How to turn off the freezer in a refrigerator Atlant with a display, if the buttons do not respond?

If the electronic panel does not respond to presses, try:

1. Disconnect the refrigerator from the network for 10-15 minutes (full reset).
2. Press and hold the button Menu (or Set) for 10 seconds to force a reboot.
3. If the display still does not work, check fuse on the control board (disassembly required).

In 80% of cases, full helps de-energization. If not, the board needs to be repaired.

Is it possible to turn off the freezer without defrosting it?

Technically yes, but this is fraught:

• 💧 Education puddles due to melting ice.
• 🔌 Short circuitif water gets on the electrical contacts.
• 🦠 The appearance of an odor due to rotting organic residues under the ice.

If the freezer is very icy, defrosting is required. In extreme cases, place towels and monitor the process.
