How to defrost the freezer in the Atlant refrigerator: a complete guide with tips 2026

A separate freezer compartment in refrigerators Atlant requires regular defrosting - even if the model is equipped with a system No Frost or Frost Free. Ice more than 5 mm thick impairs heat transfer, causes the compressor to wear out and increases energy consumption by 15–30%. In this article we will look at how to defrost a freezer Atlant quickly, safely and without consequences for equipment - from preparation to final cleaning.

Features of two-chamber models Atlant (for example, MHM 2835-080, MHM 1708-01 or MX 2826-06) - the ability to turn off the freezer compartment separately from the refrigerator compartment. This simplifies the process, but requires knowledge of the nuances: from the correct position of the temperature regulator to ways to speed up the melting of ice. We have collected proven methods that are relevant for models from 2018 to 2026, and added care tips that will extend the life of the equipment.

Why ice builds up in the Atlant freezer and when to defrost it

Even in models with automatic defrosting frost forms over time. Reasons:

• 🔹 Frequent opening of the door - warm air condenses on the evaporator, turning into ice. This is especially true for families with children or when storing food in loose bags.
• 🔹 A loose fit of the seal —if the Door Seal rubber is torn or deformed, moisture gets inside. Check the seal: there should not be a sheet of paper between it and the body.
• 🔹 Overload with food - disrupts the circulation of cold air. In the area near the fan (if any) ice accumulates faster.
• 🔹 High humidity in the room - relevant for kitchens without a hood or during the rainy season.

Defrost at:

• 📏 Ice thickness more than 5–7 mm (optimally - at 3–4 mm).
• ❄️ Appearance snow "coat" on walls or products.
• 🔊 The compressor noise increases - it starts working almost without interruption.
• 💡 The indicator is lit ALARM or HIGH TEMP (in models with a display).

In models Atlant s manual defrosting (for example, MX 2821-03) ice grows faster - it is recommended to defrost them every 3-4 months. For No Frost (MHM 2848-90, MHM 1843-80) 1-2 times a year is enough, but the procedure cannot be completely ignored: the system removes frost, but does not remove fat and bacteria.

⚠️ Attention: If ice forms unevenly (only in one corner or at the bottom), this may indicate freon leak or a thermostat malfunction. In this case, defrosting will not help - repair is needed.

Preparing for defrosting: what to do before turning off the freezer

Improper preparation can lead to food spoilage, kitchen flooding or equipment breakdown. Follow the checklist:

Remove all products and pack them in thermal bags|Unplug the freezer (pull out the plug, not just press the button)|Place a tray to collect water|Prepare rags and sponges|Check the room temperature (optimally 18–25°C)-->

Where store food during defrosting:

• 🧊 Thermal bag or refrigerator bag with cold batteries - will maintain the temperature for up to 12 hours.
• ❄️ Snow/ice in the basin - wrap the food film and place in a container with ice.
• 🏠 Balcony/loggia - only if it is winter outside and the temperature is below +5°C.
• 🚫 Do not leave meat, fish or dairy products at room temperature for longer than 2 hours!

If the freezer is Atlant two-chamber (for example, MHM 2835-080), the refrigerator compartment can be left running. To do this:

1. Find on the control panel a button or knob with an icon 🏔️ (freezer) or inscription FREEZER.
2. Turn the knob to position OFF or press freezer off button (in models with electronic control).
3. Make sure that the freezer indicator goes off and the refrigerator compartment continues to work (the light is on FRIDGE).

Step-by-step instructions: how to defrost an Atlant freezer

The process takes from 3 to 12 hours depending on the thickness of the ice and the chosen method. We will analyze natural. melting (the safest way) and accelerated methods.

Method 1: Natural defrosting (3–12 hours)

Suitable for all models Atlant, including old (MX 2820) and new (MHM 2848-90).

1. Disconnect the freezer from the network or turn it off separately (if a two-chamber model).
2. Open the door open and secure it (for example, with a chair).
3. Place the tray for water under the drainage hole (usually located on the back wall).
4. Wait until the ice has completely meltedDo not try to chip off the ice. with a knife - this will damage the evaporator!
5. Remove water with a sponge or rag, wipe the walls with a soda solution (1 tablespoon per 1 liter of water).

Method 2: Accelerated defrosting (1–3 hours)

To speed up, use:

• 💨 Fan — direct the air flow into the freezer (the door should be open) the ice will melt 2-3 times faster.
• 🧊 Containers with hot water — place pots or bowls with water (60–70°C) on the shelves. Change the water every 15–20 minutes.
• 🔥 Hair dryer - keep at a distance of 30 cm from the walls, use cold or warm (not hot!) mode. seal!

⚠️ Attention: Never use boiling water, sharp objects (knives, forks) or abrasive detergentsto speed up defrosting. This will damage the evaporator coating and lead to corrosion.

What to do if the water does not drain through drain hole?

If water accumulates at the bottom of the freezer and does not drain into the tray, the drain hole is clogged. Clean it with a cotton swab or soft wire. In models Atlant the hole is usually located on the back wall at the bottom. After cleaning, rinse it with warm water and citric acid (1 teaspoon per glass of water).

Cleaning and disinfection after defrosting

After the ice has melted, you need to not only wipe the water, but also disinfect the camera. This will eliminate odors and prevent the growth of bacteria (for example, Salmonella or Listeria).

Step-by-step cleaning:

1. Remove remaining water with a dry cloth or sponge.
2. Prepare a cleaning solution:
   • For degreasing: 2 tbsp. soda per 1 liter of warm water.
   • For disinfection: 1 tbsp vinegar (9%) or 1 tsp hydrogen peroxide per 1 liter of water.
   • For eliminate odors: a few drops of lemon or tea essential oil wood.

Wipe all surfaces, including seals, shelves and drawers. For hard-to-reach places, use a toothbrush.

Rinse with clean water and wipe dry.

Ventilate the freezer 15–20 minutes with the door open.

For models with with a fan (system No Frost) special Pay attention to the grill on the back wall - dust and grease accumulate there. Wipe it with a damp sponge soaked in soapy water, then dry it.

How to turn on the Atlant freezer after defrosting

Proper start-up after defrosting will extend the life of the compressor and prevent network overload. Follow the algorithm:

1. Close the door and make sure that the seal fits tightly.
2. Connect the freezer to the mains (insert the plug into the socket).
3. Set the temperature:
   • For mechanical regulator (for example, in MX 2826-06) turn the knob to 3–4 (middle position).
   • For electronic control (for example, in MHM 2848-90) press the button FREEZER and install -18°C.

Wait for the signal (in models with display the indicator will light up OK or go out ALARM).

Load food only after 1-2 hours, when the freezer reaches the desired temperature.

If the freezer does not turn on:

• 🔌 Check whether the plug is firmly inserted into the socket.
• ⏻ Make sure defrost button (if any) is returned to the original position.
• 🔋 Wait 5-10 minutes - the compressor protection against frequent switching may have worked.

⚠️ Attention: If after turning on the freezer Atlant it hums, but does not freeze., or an error flashes on the display (for example, E1, E2), do not try to repair it yourself. This may indicate compressor malfunction or refrigerant leak - contact a service center.

How often to defrost an Atlant freezer: recommendations for models

The frequency of defrosting depends on the type of system and operating conditions. The table below contains recommendations for popular models. Atlant:

Simple rules will help reduce the frequency of defrosting:

• 📦 Close food tightly —use containers with lids or cling film.
• 🚪 Do not keep the door open longer than 10-15 seconds.
• 🧴 Wipe the seal once a month silicone grease (for example, WD-40 Specialist).
• 🌡️ Do not put hot foods in the freezer —let them cool to room temperature temperature.

Typical mistakes when defrosting an Atlant freezer

Even experienced users sometimes make mistakes that lead to breakdowns or rapid re-icing Let's look at the most common ones:

1. Using sharp objects to chip ice

   A scratched evaporator loses thermal conductivity, and microcracks become centers of corrosion. Instead of a knife, use a plastic scraper or a wooden spatula.

2. Turning on the freezer immediately after washing

   Moisture on the walls will freeze, and ice will form within a few hours. Minimum drying time - 30 minutes (optimally - 1 hour).

3. Ignoring cleaning the drainage holes

   A clogged hole leads to the accumulation of water at the bottom and the appearance of mold. Clean it with a cotton swab after each defrosting.

4. Defrosting at high room temperatures

   If the kitchen is hotter than +30°C, the compressor will operate at maximum power after turning on. The optimal temperature for defrosting is 18–25°C.

5. Use of aggressive chemicals

   Bleach, acetone or abrasive powders destroy plastic and rubber. Use only baking soda, vinegar or special products (for example, Topperr 3101).

FAQ: Frequently asked questions about defrosting the Atlant freezer

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

Yes, in two-chamber models (for example, MHM 2835-080) the freezer can be turned off separately. For this:

1. Find a button or regulator with a freezer icon on the panel (usually 🏔️).
2. Turn it to position OFF or press the off button.
3. Make sure that the freezer indicator goes off and the refrigerator compartment is working (the light is on FRIDGE).

In single-chamber models (for example, MX 2820-01you will have to turn off the entire refrigerator.

How many How long does the Atlant freezer defrost?

Time depends on the method:

• Natural thawing: 6–12 hours (with ice thickness 1–2 cm).
• With a fan: 2–4 hours.
• With hot water: 1–2 hours.
• With a hairdryer: 1–3 hours (depending on power).

In models c No Frost ice melts faster - in 3-6 hours.

What to do if, after defrosting, the Atlant freezer does not freeze?

Check:

1. Power: the plug must be firmly inserted into the socket, and the mains voltage must be stable (220V ± 10%).
2. Thermostat: in mechanical models, turn the knob to maximum and listen - if the compressor does not start, the thermostat is faulty.
3. Door: it should close tightly. You can check it with a sheet of paper - if it falls out, the seal needs to be replaced.
4. Display: if the error is on (for example, E1), contact service. Possible freon leak or breakdown of the sensor.

If the freezer hums, but does not freeze, probably compressor jammed is needed repair.

Is it possible to use a steam generator to speed up defrosting?

No! The steam generator creates excess moisturewhich:

• Penetrates the insulation of the walls, worsening thermal insulation.
• Can cause a short circuit if it gets into electrical contacts.
• It will lead to rapid re-icing after switching on.

A safe alternative is hot water containers (not boiling water!) or a fan.

How defrost the Atlant freezer if you don’t have time to wait?

For emergency defrosting (for example, before leaving):

1. Take out all the products and pack them in thermal bags.
2. Place the pan in the freezer with hot water (70–80°C) on a wooden stand (not on plastic!).
3. Cover the pan with a lid - steam will speed up the melting.
4. Replace the water every 10 minutes.
5. After 30–40 minutes, remove the remaining ice with a plastic spatula.

This method reduces the time to 1–1.5 hours, but requires constant monitoring.
