Defrosting the freezer compartment of the Atlant refrigerator separately from the main one compartment: instructions 2026

Owners of refrigerators Atlant with a system No Frost or drip defrosting sooner or later face the need to clear the freezer compartment of ice - even if the main compartment is working properly. The peculiarity of the models Atlant (for example, MHM 2835-080, MX 2824-66 or XM 4626-000) is that their design allows you to defrost the freezer isolatedwithout interrupting the operation of the refrigerator compartment. This is convenient if you do not want to risk food or waste time on complete defrosting.

However, not all users know how to do this correctly without damaging the equipment. Errors are fraught: from thermostat breakdown due to a sharp temperature change to short circuit when handling moisture incorrectly. This article contains a step-by-step algorithm taking into account the nuances of specific models, a defrosting time table and answers to frequently asked questions. And also proven life hacks on how to speed up the process without a hairdryer and scrapers.

Let's immediately clarify: if your Atlant equipped with a system Full No Frost (for example, models XM 6025-031 or NF 3827-080), separate defrosting of the freezer may not be necessary at all - ice forms there only if there is a malfunction. In other cases (drip system or Frost Free), the procedure is relevant. You can check the type of your model by the marking on the sticker inside the chamber or in the product passport.

Why does the Atlant freezer need to be defrosted separately

In refrigerators Atlant with two compressors (for example MHM 2842-90) or one, but with independent control of the chambers (XM 4426-000), the freezer compartment can be turned off selective. This provides three key advantages:

• 🍎 Safety of food: the refrigeration compartment continues to work, which means that perishable products (dairy, meat, herbs) will not spoil after 2-4 hours of defrosting.
• ⚡ Saving energy: no need to turn off the entire device and waste time on re-cooling both compartments.
• ❄️ Prevention of breakdowns: frequent complete defrosting accelerates the wear of seals and the thermostat. Local thawing spares equipment.

In addition, in freezers Atlant ice often forms unevenly: a thick layer of ice accumulates at the back wall (where the evaporator is located), while on There are almost no shelves of it. If you try to remove ice mechanically (with a knife, spatula), you can damage the plastic or refrigerant pipes. Proper defrosting solves this problem without risks.

Important: if your model is equipped with one compressor (for example, MX 2821-66), but with a button Super Freeze, turning off the freezer separately may not be possible. In this case, you will have to defrost the entire refrigerator or use express methods (about them in the section on accelerating the process).

Preparing for defrosting: what needs to be done in advance

Despite its apparent simplicity, defrosting the freezer requires preparation. Here is a checklist that will help you avoid common mistakes:

Turn off the freezer with the button on the panel or the temperature regulator

Transfer the food to a thermal bag or another refrigerator

Put towels or a tray under the bottom of the chamber to collect water

Turn off the function “Super Freeze”, if it is active

Prepare containers with hot water (to speed up the process)-->

Pay special attention products. If you do not have a second refrigerator, use:

• 🧊 Thermal bags with cold accumulators (even frozen water bottles wrapped in a towel will do).
• 📦 Boxes with polystyrene foam (for example, from under appliances) - they preserve well cold.
• ❄️ Ice from the freezer: put it in bags and put it together with the food in the bag.

If there are products in glass jars in the freezer (jam, pickles), do not place them close to each other when defrosting - when thawing, they can burst due to temperature changes. The same applies to bottles with carbonated drinks.

⚠️ Attention: Do not use to collect melt water metal containers (basins, pans). When they come into contact with the cold walls of the freezer, they can freeze, and if you try to move them away, they can damage the coating.

Step-by-step instructions: how to defrost the Atlant freezer separately

The algorithm depends on the control type of your model. Below is a universal diagram suitable for most refrigerators Atlant 2015–2026 model years.

Step 1: Disabling the freezer

In models with mechanical control (for example, MHM 1708-01) turn the freezer temperature control to position OFF or 0. In refrigerators with electronic panel (XM 4626-000, NF 3827-080, press the button Freezer (or Freezer compartment) and hold for 3-5 seconds until the indicator goes off.

If the button does not respond, check:

• 🔌 Is the refrigerator connected to the network (sometimes the panels “freeze” during power surges).
• 🔄 Is the mode activated Vacation (in this case, the freezer may be blocked).
• 📄 Does your model correspond to the possibility of separate shutdown (see instructions).

Step 2: Removing ice

After turning off, wait until the ice begins to thaw naturally (usually this takes 1-2 hours). Do not try to speed up the process with a hairdryer or hot water at this stage - a sudden temperature change can damage the plastic.

When the ice becomes soft, remove it:

• 🧽 Plastic spatula (usually included with the refrigerator).
• 🧼 Warm sponge water (not higher than 40°C).
• 🧊 A special scraper (sold in hardware stores).

⚠️ Attention: If the ice does not come away from the walls, do not use knives or forks. In freezers Atlant the refrigerant pipes run close to the inner walls - they are easy to puncture.

Step 3: Cleaning and drying

After removing the ice, rinse the chamber warm soda solution (2 tablespoons per 1 liter of water) or with a special product for refrigerators. Avoid aggressive chemicals (for example, Domestos) - they can damage the seals.

Wipe the walls dry with a soft cloth and leave the door open for 15-20 minutes to allow the moisture to evaporate. In models with No Frost (XM 6025-031) this time is enough for the ventilation system to dry the chamber on its own.

Step 4: Turning on the freezer

Before turning on, check:

• 🔍 Sealant —it should be clean and fit snugly to the body.
• 📏 Shelves and drawers —they should fit into place without distortion.
• 🌡️ Temperature mode —install on -18°C (optimal for storage).

In models with electronic control, the indicator may light up after switching on Alarm —this is normal. It will go out after 10–15 minutes when the chamber reaches the desired temperature.

How long does defrosting take: table on models

Thawing time depends on the thickness of the ice, room temperature and type of system. Below are approximate data for popular models Atlant:

If the ice is thicker than 15 mm, the defrosting time can increase to 4-5 hours. In this case, use acceleration methods (about them in the next section).

⚠️ Attention: In refrigerators Atlant s one compressor (for example, MX 2821-66) Long-term defrosting of the freezer (more than 3 hours) can lead to motor overheating. Make sure that the refrigeration compartment does not turn off along with the freezer.

How to speed up the defrosting of an Atlant freezer: 5 safe ways

If time is short and the layer of ice is thick, you can shorten the process without risk to equipment. Here are proven methods:

• 💧 Containers with hot water: Place pots or bowls of water (temperature no higher than 60°C) on the freezer shelves. Change the water every 15–20 minutes. Do not place containers on the bottom of the chamber —this may damage the drainage hole.
• 🧂 Saline solution: soak a rag in a salt solution (3 tbsp. spoons per 1 liter of water) and place on ice. Salt speeds up the melting, but after the procedure the chamber must be rinsed thoroughly.
• 📰 Newspaper or paper towels: soak them in warm water and place them on the ice build-ups. Paper absorbs moisture and speeds up the process.
• 🌀 Fan: direct a stream of air (at room temperature!) into the open freezer. Do not use heaters —they dry out the seals.
• 🧊 Ice from the freezer: if there are pieces of ice in the chamber, put them in a bag and use them to cool the food in the thermal bag. This will make room for melt water.

What not to do:

• 🔥 Use hairdryer —a flow of hot air deforms the plastic and can melt the seal.
• ❄️ Chip the ice knife or fork —risk of puncturing the evaporator.
• 🧴 Apply defrosting products (for example, sprays) - they can damage the coating.

What happens if you interrupt defrosting halfway?

If you turn on the freezer until the ice is completely removed, the remaining moisture will freeze even more densely. In addition, uneven defrosting can lead to clogging of the drainage system (water will accumulate under the drawers). In the worst case - to evaporator corrosion due to constant humidity.

Common mistakes and how to avoid them

Even experienced users sometimes make defrosting errors. Here are the top 5 mistakes and their consequences:

• 🚫 Ignoring the drain hole: if it is not cleaned, melt water will accumulate under the drawers and then freeze, creating new ice. Clean the hole with a cotton swab after each defrosting.
• 🚫 A sharp change in temperature: if you put boiling water in the freezer or turn it on immediately after washing, the plastic may crack or be damaged thermostat.
• 🚫 Use of abrasive agents: powders and hard brushes scratch the coating, which subsequently accelerates the formation of ice.
• 🚫 Closing the door until completely dry: remaining moisture will lead to new ice within week.
• 🚫 Disconnecting the refrigerator from the mains (in models with one compressor): this interrupts the operation of the refrigerator compartment and can lead to food spoilage.

If after defrosting the freezer became makes more noise than usual or does not gain temperature, check:

• 🔌 Power —the contact in the socket may have come loose.
• 🌡️ Thermostat —if it is broken, the chamber will not cool.
• 💨 Fan (in models No Frost) - if it is blocked by ice, defrosting may not help.

⚠️ Attention: If your refrigerator Atlant was produced before 2018, it may be missing protection against voltage surges. After defrosting, do not turn on other powerful appliances (for example, a washing machine) at the same time as the freezer - this may cause a power surge and breakdown of the compressor.

What to do if the Atlant freezer does not defrosting

Sometimes even after turning off the ice remains in place. Causes and solutions:

• 🔌 The freezer did not turn off: check whether the indicator on the panel is on. If not, the button or electronic module may be broken. Solution: unplug the refrigerator for 10 minutes, then try again.
• ❄️ Ice “stuck” to the walls: this happens when it has been idle for a long time without defrosting (more than 1 year). Solution: use plastic spatula warm water, but without effort.
• 🧊 The drainage hole is clogged: the water does not leave, but freezes again. Solution: clean the hole with wire and rinse with a soda solution.
• 🌡️ The temperature sensor is faulty: the freezer “thinks” it has not yet warmed up. Solution: diagnostics by a technician is required.

If the ice does not melt for more than 4 hours, and the room temperature is above 20°C, the problem may be thermal insulation. Check:

• 🚪 Seal —it must be intact, without cracks.
• 🔍 Door —it must close tightly, without cracks.
• 💡 Backlight —if it does not turn off when closing, it means the door is not locked.

In models with electronic control (XM 6025-031, NF 3827-080) when the panel freezes, resetting the settings will help. To do this:

1. Disconnect the refrigerator from the network for 5 minutes.
2. Turn on and immediately press the buttons Super Cool + Super Freeze for 10 seconds.
3. Wait for reboot (indicators blink).

FAQ: Frequently asked questions about defrosting the Atlant freezer

Is it possible to defrost the Atlant freezer without turning off the refrigeration compartment?

Yes, in most models Atlant s two compressors or independent camera control (for example MHM 2842-90, XM 4626-000), the freezer can be turned off separately. The refrigerator compartment will operate as normal. The exception is models with one compressor (for example, MX 2821-66), where when the freezer is turned off, the main chamber also stops working.

How often do you need to defrost the Atlant freezer?

The recommended frequency depends on the type of system:

• Drip defrosting (models MHM 2835-080, MX 2824-66): once every 3–6 months.
• No Frost (XM 6025-031, NF 3827-080): once every 1–2 years (or when ice appears).
• Frost Free (XM 4626-000): once a year.

If ice forms faster, check seal and drainage hole - they can cause accelerated growth of ice.

Why after defrosting the Atlant freezer not freezing?

Possible reasons:

• 🔌 The compressor does not turn on —check if the light inside the chamber is on.
• 🌡️ Broken thermostat —if the motor is running, but there is no cold, the sensor needs to be replaced.
• ❄️ Freon leak —if the refrigerator did not freeze well before defrosting, the tube may be damaged.
• 💨 The filter drier is clogged (in models with No Frost) - cleaning required.

First turn off the refrigerator for 10 minutes and turn it on again. If the problem persists, call a specialist.

Is it possible to use the product for defrosting refrigerators in the Atlant freezer?

Not recommended. Most products (for example, Indesit, Sanocontain aggressive components that can:

• Damage plastic coating cameras.
• Corrode seal, which will lead to a violation of the tightness.
• Leave chemical smellwhich will absorb the products.

Better use warm water with soda or special napkins for refrigerators.

How to defrost an Atlant freezer if the ice has not melted for 5 hours?

If natural defrosting does not help:

1. Check whether the freezer has turned off (the indicator should go out).
2. Use warm compresses: soak towels in water (40–50°C) and place on ice.
3. If the ice is thicker than 2 cm, carefully separate it plastic scraperby prying from the edges.
4. Check drainage hole - if it is clogged, the water does not drain and the ice does not melt.

If all else fails, perhaps defective defrost heater (in models with No Frost). In this case, diagnostics are needed.
