The appearance of an unpleasant odor in the refrigerator Atlant is always a signal that the balance inside is disturbed cleanliness or technical malfunction. Even if you regularly check expiration dates on your food, the smell can appear suddenly and should not be ignored. It not only makes cooking an unpleasant process, but may also indicate the growth of bacteria, mold or a breakdown of the water drainage system.
Owners of Belarusian equipment often encounter the fact that odors are absorbed into the plastic parts of the body, especially when it comes to models with the system No Frost. However, even in classical drip systems, problems with water stagnation may arise. The first step is to conduct a thorough diagnosis in order to understand the source of the stench before using aggressive chemicals.
In this article we will examine in detail all the possible causes, from basic stale cheese to a clogged drainage hole. You will learn how to properly defrost completely, how to wash internal surfaces, and when to call a professional. Proper care of the refrigerator Atlant will extend its service life and preserve the freshness of your products.
Primary diagnostics: products or equipment?
Before disassembling the unit, you need to exclude the most commonplace option - spoiled products. Sometimes the smell can come from a long-forgotten bag of vegetables that has rolled into the far corner of the freezer. In refrigerators Atlant with a ventilation system, odors spread instantly, so even one source can “aromatize” the entire volume.
Carry out a complete audit of the contents. Remove all shelves and drawers to gain access to hard-to-reach areas. Pay special attention to door seals and joints of plastic panels, where crumbs could get stuck or liquids could spill. If, after complete cleaning and airing, the smell returns after a few hours, the problem lies deeper.
- 🍞 Check baked goods and pastries - they often become a source of sour odor.
- 🥩 Inspect meat and fish, even if they are in the freezer; with frequent temperature fluctuations, they could begin to deteriorate.
- 🧀 Pay attention to soft cheeses and open jars of sauces that could have spilled.
- 🥦 Look in the vegetable compartment - rotting root vegetables gives a persistent earthy smell.
⚠️ Attention: If you smell burning or burnt plastic, immediately unplug the refrigerator! This may indicate overheating of the wiring or compressor, which requires the intervention of an electrician.
Often the cause is not the product itself, but its packaging. Poor quality plastic containers or plastic bags can absorb odors and store them for a long time, even if the product has already been thrown away. Therefore disinfection of all containers stored in the refrigerator is a mandatory diagnostic step.
Problems with the drainage system and melt water
One of the most common reasons for the appearance of a musty smell in refrigerators Atlant the drainage hole is clogged. In models with a drip defrosting system, condensate flows down the back wall into a groove and goes through a tube into the evaporator. If this path is clogged with crumbs, mold or mucus, the water stagnates and begins to rot.
It is not difficult to find the drainage hole - it is located in the lower part of the rear wall of the refrigerator compartment. Clean it carefully using a special brush, cotton swab or soft wire. Do not use sharp metal objects to avoid damaging the plastic or tube.
In models with No Frost the situation is more complicated: there the drainage removes water from the evaporator, which is hidden behind a plastic panel. If the smell is coming from the freezer or underneath the unit, ice may have blocked the drain and water has gotten under the casing. In this case, complete defrosting will be required within 24 hours.
| System type | Drain location | Cleaning frequency | Clogging symptoms |
|---|---|---|---|
| Drip | At the bottom of the back wall | Once every 3-4 months | Puddles at the bottom, the smell of dampness |
| No Frost | Behind the back panel | Once a year (prof.) | Ice in freezer, water under the drawers |
| Combined | In both compartments | Once every six months | Combined signs |
After cleaning, be sure to rinse the channel with warm water to make sure it is passable. If the water drains slowly, the procedure must be repeated. Stagnant moisture is an ideal environment for the growth of bacteria, which creates that same unpleasant “swampy” smell.
Features of the No Frost system and the smell of plastic
Refrigerators Atlant with technology No Frost (or Full No Frost) have a complex air circulation system. The fan constantly moves air masses between the freezer and refrigerator compartments. This means that any smell that appears in one compartment instantly spreads throughout the entire volume.
Often owners of new equipment complain about the specific smell of plastic. This is normal for the first weeks of use. However, if the smell does not disappear for months, perhaps the problem is poor-quality plastic of the internal panels or that dirt has gotten inside the ventilation system.
In the system No Frost the condition of the air filter is important, if it is provided by the model. Over time, the carbon filter becomes saturated and ceases to neutralize odors, and sometimes itself becomes a source of odors. Check the instructions for your model: if there is a filter, it needs to be changed every 6-12 months.
- 🌬️ Air circulation can carry the smell of rotten vegetables from the bottom drawer to the upper shelves.
- ❄️ An ice coat on the evaporator (if faulty) can give the smell a tint dampness and mustiness.
- 🔧 The fan can become clogged with dust and lint, which begins to smell when the motor heats up.
To eliminate odors in the system No Frost often requires disassembling the rear panel to access the evaporator. If you are not confident in your abilities, it is better to entrust this procedure to specialists, as there is a risk of damaging fragile plastic latches or pipes.
Mold and bacteria: complete sanitation
If simple methods did not help, it means that a colony of bacteria or mold has settled in the refrigerator. Mold spores can penetrate microcracks in plastic and rubber seals, from where they are difficult to wash with ordinary water. This requires disinfection using safe but effective means.
In no case use chlorine-containing products (for example, "Whiteness") in their pure form, especially in refrigerators Atlant with white plastic - it can turn yellow, and the smell of chlorine will be very difficult to remove. It is better to use baking soda, vinegar solution or special products for cleaning refrigerators.
☑️ Complete sanitization algorithm
Pay special attention rubber door seal. It is in its folds that black mold most often hides. Wipe the seal thoroughly, pulling it with your fingers to get to the inner folds. If mold has eaten deep into the rubber, the seal may need to be replaced.
⚠️ Attention: When using vinegar or citric acid, be sure to ventilate the room well. Acid fumes can be unpleasant for the respiratory tract, and their residual odor on products is undesirable.
After wet cleaning, all surfaces must be completely dry. Humidity is the main friend of bacteria. Leave the doors open for several hours (or overnight) so that the insides of the refrigerator Atlant dry and ventilate.
Faults that cause odor
Sometimes a smell is not the result of your carelessness, but a symptom of a technical breakdown. If you have tried all cleaning methods and the “aroma” remains, you should take a closer look at the operation of the unit. Some malfunctions can lead to the appearance of specific odors.
For example, if the defrost heating element in the system fails No Frost, the ice begins to melt unevenly, water can fall on the heating elements or into the pan, where the process of rotting of the organic matter that got there earlier begins. The smell can also be caused by an overheating compressor or melting wire insulation.
How to distinguish the smell of food from the smell of equipment?
The smell of food is usually organic (sour, rotten). The smell of equipment is often chemical, reminiscent of burnt rubber, smoke or overheated dust. If it smells like “electricity”, immediately contact a technician.
Another rare but possible reason is the ingress of freon. The refrigerant itself is often odorless, but oil may come out of the compressor along with it, which has a specific chemical odor. If you notice oily stains near the refrigerator and smell a chemical smell, this is a cause for alarm.
- 🔥 A burning smell indicates electrical problems or overheating of the motor.
- 💧 The smell of a sewer or swamp often indicates a problem with the drainage or siphon (if there is one).
- 🧪 A chemical smell may indicate a freon leak or plastic dissolution.
In such cases, independent repairs can be dangerous. It is better to call a specialist from the service center Atlantwho will diagnose the tightness of the system and electrical circuits.
Folk methods and odor absorbers
After the cause has been found and eliminated, and the refrigerator has been washed, you can use traditional methods to consolidate results and preventive measures. In refrigerators Atlant natural absorbents that do not require electricity and are safe for food work well.
The most popular and effective method is the use of activated carbon. Grind 10-15 tablets into powder, scatter into saucers and place on shelves. Coal perfectly absorbs foreign odors. You need to change such a “tablet” once a month.
They also do an excellent job:
- 🍞 A piece of black bread (leave overnight).
- 🍋 A slice of lemon or citrus zest (gives a pleasant aroma).
- ☕ Dry ground coffee in an open container.
- 🍚 Rice in a fabric bag.
Do not use strong-smelling chemical air fresheners - their smell can be absorbed into products, especially butter and milk. Natural products in this regard are much safer and more effective for the food area.
Is it possible to wash a refrigerator with soap?
Using regular toilet or laundry soap is not recommended. It leaves a greasy film, which itself can begin to smell over time, and is difficult to wash off from plastic. It is better to use special products or a soda solution.
How often does Atlant No Frost need to be defrosted?
Technically, the system No Frost does not require defrosting to remove ice. However, once a year (or at least once every six months), the refrigerator must be turned off, defrosted and washed for hygiene and checking the drainage system.
Why did the smell return after cleaning within a day?
Most likely, the source of the smell (mold or rotten water) remained in hidden cavities, for example, behind the back panel or in the drainage hose. A deeper cleaning with disassembly is required.
Is the smell of plastic in a new refrigerator harmful?
This is normal in the first weeks of operation. However, if the smell is strong and does not go away for more than a month, this may indicate poor quality materials. In this case, you should contact the store for warranty.
What is the best way to wipe the plastic inside?
The best option is a solution of baking soda (1 tablespoon per 1 liter of warm water) or a weak solution of table vinegar. They degrease, disinfect and do not leave harmful traces.
