Two-compressor refrigerators Atlant are valued for their independent control of the freezer and refrigerator compartments, but their defrosting has nuances that are often overlooked. If your freezer is covered with a thick layer of ice and the compressor starts working non-stop, it’s time to start the procedure. Unlike single-compressor models, here you can only turn off the freezer compartment without affecting the refrigerator compartment. This saves time and energy, but requires strict adherence to the algorithm.
Many users make critical mistakes: they turn on heating devices near the seals, use sharp objects to chip ice, or forget to dry the chamber after defrosting. This article contains step-by-step instructions taking into account the specific features of the models, tips for speeding up the process and answers to frequently asked questions. We will also look at how often you need to defrost a two-compressor freezer and what to do if the ice builds up too quickly. step-by-step instructions taking into account the features of the models Atlant, tips to speed up the process and answers to frequently asked questions.

Why is it important to defrost a two-compressor refrigerator Atlant correctly
A thick layer of ice in the freezer is not only an aesthetic problem. It worsens heat transfer, causing the compressor to work harder. In models Atlant with two compressors (MHM 2835-080, MHM 2844-90 etc.), an ice “coat” thicker than 5 mm increases energy consumption by 15–20% and reduces the service life of the equipment. In addition, ice can block ventilation holes, which leads to uneven cooling of products.
Feature of two-compressor systems — opportunity isolated shutdown of the freezer. This means that the refrigerator compartment will continue to operate as normal while you defrost the freezer. However, incorrect actions (such as abrupt mechanical deicing) may damage the evaporator or drainage system. In the most advanced cases, this leads to a freon leak and expensive repairs.
Another nuance - sealing rubber bands. In models Atlant they often stick to the body due to temperature changes. If they are torn off by force, the seal of the chamber will be broken, and the ice will grow even faster. Therefore, defrosting must be carried out carefully, taking into account the materials and design of a particular model.
Preparing for defrosting: what needs to be done in advance
Before turning off the freezer, prepare for the procedure. This will save time and prevent food spoilage. Start with emptying the chamber: take out all the products and place them in thermal bags or containers with ice. If it’s winter outside, you can temporarily take them out onto the balcony (at a temperature no higher than −5°C).
Next, check:
- 🔌 Availability of an outlet with grounding —after defrosting, the refrigerator will need to be plugged in, and it is better to use a working outlet.
- 🧊 Container for collecting water —a tray or large bowl for draining melt water (in models Atlant the drainage hole is located at the back, but some of the water can flow out from the front).
- 🧽 Soft rags and sponges — to remove moisture and clean surfaces. Do not use abrasive sponges!
- ⏱️ Time —defrosting naturally takes 6–12 hours, so it is better to start the procedure in the evening.
If your model has a function Super Freeze (super freeze), turn it off 1-2 hours before defrosting. This will reduce the load on the compressor when it is turned on again. Also check instructions for your model —some refrigerators Atlant (for example, MHM 2832-80) have recommendations for preparing the drainage system before defrosting.

Step-by-step instructions: how to defrost the freezer compartment in a refrigerator Atlant
In two-compressor models Atlant the freezer compartment can disconnect separately from the refrigerator compartment. To do this:
Find on the control panel (or inside the camera) freezer switch. In most models, it is indicated by a snowflake ❄️ or the inscription
Freezer.Turn the regulator to position
OFFor press the off button (in electronic models, for example, Atlant XM 6025-031). The refrigerator compartment will continue to work.Open the freezer door and fix it in the open position (you can use a stand or rope).
Wait until the ice begins to melt naturally by. Do not use a hairdryer, heaters or hot water - this can deform the plastic and damage the seal.
If the ice is thick (more than 1 cm), placing it on the freezer shelves will help speed up the process. The water needs to be changed every 20–30 minutes. For models with a system warm water in bowlsplaced on freezer shelves. The water needs to be changed every 20–30 minutes. For models with system No Frost (for example, Atlant MHM 2808-90), defrosting takes less time - usually 3-5 hours.
When the ice has completely melted, wipe the chamber with a soft cloth soaked in a solution of baking soda (1 tablespoon per 1 liter of water). Pay special attention to:
- 🧊 Evaporator (rear wall of the chamber) - dirt often accumulates here.
- 🕳️ Drainage hole - clean it with a cotton swab to avoid water stagnation.
- 🚪 Sealing rubber band —wash it with soapy water and dry it.
After cleaning, leave the door open for 1-2 hours so that the camera is completely dry. Only then can you turn the freezer back on.
How long does defrosting take: table by model
Defrosting time depends on the thickness of the ice layer, the room temperature and the type of cooling system. Below are approximate data for popular two-compressor models Atlant:
| Refrigerator model | Type of defrosting | Ice thickness, mm | Defrost time, h | Features |
|---|---|---|---|---|
| Atlant MHM 2835-080 | Drip | up to 5 | 4–6 | The drainage hole requires cleaning after defrosting |
| Atlant MXM 2844-90 | No Frost | up to 3 | 2–3 | Ice builds up only when the fan is faulty |
| Atlant XM 6025-031 | Drip | 5–10 | 8–12 | It is recommended to defrost at least once every 4 months |
| Atlant MHM 2808-90 | No Frost | up to 2 | 1–2 | Independent defrosting is required only if the system fails |
If defrosting takes significantly longer than indicated in the table, check:
- 🔌 Door closure tightness —the seal may be worn out.
- ❄️ Fan operation (in models with No Frost)—if it does not rotate, the ice will melt slowly.
- 🌡️ Room temperature —at +10°C and below, the process will take 30–50% longer.
Common mistakes and how to avoid them
Even experienced users sometimes make mistakes that lead to breakdowns or accelerated ice growth. Here are the most common:
Using sharp objects to chip ice. Knives, forks and other metal tools can puncture the evaporator or damage plastic parts. Instead, use plastic scraper or a wooden spatula.
Use of hot water or a hair dryer. Sharp temperature changes deform the seal and can cause cracks in the plastic. It is acceptable to use warm water (not higher than +40°C) in bowls.
Incomplete drying of the chamber. Remaining moisture will lead to rapid re-icing. After defrosting, wipe all surfaces dry and leave the door open for 1-2 hours.
Ignoring the drainage holes. If it is not cleaned, water will accumulate at the bottom of the chamber, creating ideal conditions for mold and bacteria.
Another typical mistake is turning on the freezer immediately after defrosting. The compressor needs time to adapt to the room temperature. In models Atlant it is recommended to wait at least 30 minutes before turning it on again.
⚠️ Attention: If after defrosting the freezer does not turn on or makes uncharacteristic sounds (knocking, grinding), immediately unplug the refrigerator. This may indicate water getting into the electrical components or a compressor failure.
How to care for the freezer after defrosting
To ensure that the next defrosting is required no earlier than 4-6 months later, follow these recommendations:
- 🧴 Lubricate the seal. Once every 2 months, apply a thin layer of silicone grease or glycerin to the elastic band. This will prevent it from cracking and sticking to the body.
- 📦 Store food correctly. Do not place hot foods or open liquids in the freezer - this increases humidity and accelerates the formation of ice.
- 🔄 Check the drainage regularly. Once every 3 months, clean the hole with a cotton swab dipped in vinegar (this will also eliminate unpleasant odors).
- ❄️ Control the temperature. The optimal mode for the freezer is −18°C. Lower values increase the load on the compressor and contribute to icing.
If your model has a function Auto Defrost (automatic defrost), do not turn it off manually. In refrigerators Atlant with this option (for example, MHM 1842-80), the system itself maintains the optimal ice level, and frequent forced defrosting can disrupt its operation.
For models with No Frost care is even easier:
- 🧹 Once every 6 months, wipe the ventilation grilles from dust.
- 🚫 Do not block the back wall with products - this interferes with air circulation.
- 🔄 Once a year, check the operation of the fan (with the refrigerator turned off).
⚠️ Attention: If, after defrosting, condensation remains in the freezer or new ice quickly grows, this may indicate freon leak or a malfunction of the thermostat. In this case, diagnostics are required at a service center.
What to do if the ice builds up too quickly
If you have to defrost the freezer more than once every 3 months, the problem lies not insufficient care, but in malfunction. Here are the most likely causes and ways to eliminate them:
| Cause | Symptoms | Solution |
|---|---|---|
| Wear of the seal | The door does not close tightly, there is ice on edges | Replace the elastic band or adjust the hinges |
| Clogged drainage hole | Water accumulates at the bottom, ice with an unpleasant odor | Clean the hole and rinse the drain hose |
| Thermostat malfunction | The compressor runs non-stop, the temperature is unstable | Replace the thermostat (a master is required) |
| Freon leakage | The freezer does not cool, the ice melts unevenly | Contact the service to refill the refrigerant |
In models Atlant with electronic control (for example, Atlant XM 6321-089) rapid ice formation can be caused by a firmware failure. Try resetting the settings to factory settings:
- Unplug the refrigerator for 5 minutes.
- Turn it back on and press the buttons at the same time
Super CoolandSuper Freezefor 10 seconds. - Wait for the sound signal - this is confirmation of the reset.
If the problem persists, check manufacture date of your model. In refrigerators Atlantmanufactured before 2018, sometimes there is a defect in the evaporator, leading to increased icing. In this case, it is recommended to contact an authorized service center for a free replacement of the part (if the warranty is still valid).
How to check the tightness of the door?
Place a piece of paper between the seal and the body. Close the door and try to remove the sheet. If it comes out without effort, the seal needs to be replaced.
FAQ: answers to frequently asked questions
Is it possible to defrost a two-compressor refrigerator Atlantwithout turning off the refrigeration compartment?
Yes, in two-compressor models the freezer and refrigerator compartments can be turned off separately. The refrigerator compartment will continue to operate normally while you defrost the freezer. The main thing is to remember to return the freezer regulator to position ON after the procedure.
What will happen if you do not defrost the freezer for years?
A thick layer of ice (from 2 cm) worsens heat transfer, forcing the compressor to work at maximum power. This leads to:
- an increase in energy consumption by 20–30%;
- overheating of the compressor and the risk of its breakdown;
- uneven cooling of products (in some areas the temperature can rise to −10°C);
- the proliferation of bacteria in hard-to-reach places under the ice.
In advanced cases, ice can block the ventilation holes, which will lead to system failure No Frost.
How to speed up defrosting if there is no time to wait?
Safe ways to speed up:
- Place bowls of warm (not hot!) water in the freezer. Change the water every 20 minutes.
- Use a fan pointing it at the open chamber (but no closer than 1 meter).
- Wipe the ice with a rag soaked in salt water (1 tablespoon of salt per 1 liter of water) - this will dissolve the top layer.
Do not use a hairdryer, heater or boiling water - this will damage the plastic and seal!
Is it necessary to defrost a refrigerator Atlant with the No Frost system?
Ideally - no, since The system No Frost prevents the formation of ice. However, defrosting may be required in two cases:
- If the fan or heating element malfunctions (ice builds up on the back wall).
- For general cleaning (every 1-2 years) to rinse the chamber and drainage.
If your freezer is with No Frost is covered with ice more than once every 6 months, this is a reason to contact the service.
Is it possible to wash the freezer with detergents containing chlorine?
No, chlorine-containing products (for example, "Whiteness") can:
- damage the plastic (it will become fragile);
- leave a persistent chemical odor that will be absorbed into the food;
- destroy the rubber seal.
For washing, use baking soda, vinegar solution (1:1 with water) or special detergents for refrigerators (for example, Topperr 3101).
