An unpleasant odor in the refrigerator is a common problem, which owners of LG equipment face, even if the model is equipped with an advanced system No Frost. The appearance of foreign aromas can be caused by many factors: from a banal forgotten piece of meat to violation of operating rules or technical malfunctions. Ignoring this problem not only creates discomfort when opening the door, but can also lead to the fact that products begin to absorb foreign aromas, losing their original taste.
Modern refrigerators of the South Korean brand are often equipped with carbon filters and antibacterial protection systems, but they are not omnipotent. If organic matter rots or products become moldy in the chamber, no amount of automation can completely neutralize the pungent aroma. Owners need to know the algorithm of actions to quickly localize the source and eliminate it.
In this article we will analyze in detail all the possible causes of odor in LG units, consider methods for deep cleaning of the evaporator and ventilation ducts, and also evaluate the effectiveness of various folk remedies and professional chemicals. You will understand when it is enough to wipe the shelves, and in which cases you will need to disassemble the back panel.
The main reasons for the appearance of an unpleasant odor
Before taking active steps to eliminate the odor, you need to accurately determine its source. In LG refrigerators, as in any other appliance, the most common culprit is spoiled food. A container with salad forgotten in the far corner, a cracked egg or a piece of fish wrapped in a leaky package can “flavor” the entire volume of the chamber in a matter of hours.
However, if you went through all the products and did not find anything suspicious, the problem may lie deeper. In models with a system No Frost odor may come from the drainage system. The condensate draining from the evaporator carries with it microparticles of food and bacteria into the pan, which is located above the compressor or in the lower part of the housing. There, this mixture heats up and begins to emit a musty smell, which is drawn back into the chamber by the fan.
It is also worth paying attention to the condition of the sealing rubber bands. They often accumulate plaque, which is an ideal environment for mold to grow. If the rubber has darkened or become sticky to the touch, it may be the source of the problem. In addition, the new LG refrigerator may have a specific plastic smell, which is normal for new equipment.
⚠️ Attention: If the smell resembles burnt wiring or scorched plastic and appears periodically while the compressor is running, immediately unplug the appliance. This may indicate overheating of the electric motor or a short circuit, which requires the intervention of a service center.
Primary treatment and defrosting of equipment
The very first and mandatory step in the fight against odors is to completely defrost the refrigerator. Even if your LG supports the automatic defrost function, for deep cleaning you need to disconnect it from the power supply for at least 12-24 hours. This will allow the ice on the evaporator (which is located behind the back wall) to completely melt and drain, taking with it any accumulated bacteria.
During defrosting, remove all shelves, vegetable drawers and containers. They must be washed separately in warm water using detergent. Pay special attention to plastic parts, since plastic has a porous structure and actively absorbs odors. If the boxes smell strongly, soak them in a solution of vinegar or soda for several hours.
After the ice has melted, wipe the inside of the chambers with a dry cloth. Do not use aggressive household chemicals with strong fragrances, as they can mix with the smell of the products and give an unpredictable result. It is best to use special means for washing refrigerators or a weak soap solution.
☑️ Defrosting algorithm
Mechanical damage to the evaporator or refrigerant tubes will lead to expensive repairs that will not be covered by the warranty.
Cleaning the ventilation and drainage system
In LG models with technology Total No Frost or Door Cooling+ air circulation occurs through special channels located on the back wall and in the door. If crumbs or liquid get into these holes, bacteria will begin to multiply there over time. To get to these areas, it is sometimes necessary to remove the plastic panel inside the chamber.
The drain hole through which moisture leaves the evaporator also requires cleaning. It often becomes clogged with mucus or food particles. You can clean it using a soft wire or a cotton swab dipped in a disinfectant solution. After mechanical cleaning, it is recommended to pour a little warm water into the hole to check the permeability.
If you are not confident in your abilities and are afraid of damaging the plastic latches when removing the panels, it is better to limit yourself to superficial cleaning of accessible areas. Disassembling the interior of an LG refrigerator can be difficult due to the fragility of the plastic at low temperatures.
How to remove the back panel in the freezer?
To remove the panel, you usually need to unscrew several screws (often they are hidden under decorative plugs) and carefully snap off the plastic clips around the perimeter. Do not use excessive force to avoid breaking the fasteners. Before removing, make sure that you do not touch the sensor wires if they are connected to the panel.
⚠️ Attention: The design of the internal panels may vary between different LG models (for example, GA, GC or GN series). Before removing any elements, check the user instructions for your specific modification.
Effective means for neutralizing odors
After mechanical cleaning and defrosting, the stage of using absorbents begins. These products help to completely remove residual odors and freshen the air. There are many folk and industrial methods, the effectiveness of which has been tested by time.
Among folk remedies, activated carbon is the leader. The tablets need to be crushed into powder, scattered into containers and placed on shelves. Coal has excellent absorbency. Baking soda has also worked well, which can be poured into an open jar or used as a wet paste to wipe the walls before the final rinse.
Natural coffee, brown bread, rice or silica gel balls also work as absorbents. It is better to use ground coffee, pour it into a sachet or an open cup. Rice and bread act more slowly, but are also effective against moisture and light odors.
Industrial absorbers, such as balls LG Clean Plus (if included) or analogues from other brands, contain special granules that not only absorb, but also neutralize ethylene, slowing down food spoilage. Their advantage is a long service life and aesthetic appearance.
Comparison table of cleaning methods
To make it easier for you to choose the best way to combat odor, we have prepared a comparison table of popular methods. It will help evaluate the time costs and effectiveness of each approach.
| Method | Efficiency | Time costs | Cost |
|---|---|---|---|
| Defrosting (24 hours) | High | Long | Free |
| Wash with soda/vinegar | Medium | Fast | Low |
| Activated carbon | Medium | Instantly | Low |
| Ozonator | Very high | Average | High |
| Special balls | Average | Instantly | Average |
As can be seen from the table, complete defrosting remains the most effective, but also the most labor-intensive method. However, for prevention it is enough to regularly use absorbents and monitor the freshness of products.
Prevention and operating rules
To ensure that the question “how to remove the smell in an LG refrigerator” no longer arises, it is important to follow the rules for storing food. All dishes with a strong odor (fish, smoked meats, spices) should be stored in hermetically sealed containers or cling film. It is better to additionally place open packages of milk or juice in separate containers.
Check your supplies regularly. Throw away expired products immediately, without waiting for mold to appear. Wipe shelves and drawers at least once a month with a damp cloth, even if there is no visible dirt. This will prevent the accumulation of bacterial plaque.
Watch the temperature. If the chamber is too warm, food will spoil faster. The optimal temperature in the main chamber should be from +2 to +4 degrees Celsius, and in the freezer - no higher than -18 degrees.
Technical faults as a source of odor
Sometimes a smell can be a symptom of a breakdown. For example, if your LG refrigerator smells plastic or burnt, it could indicate faulty wiring, an overheated compressor, or a problem with the start relay. In such cases, operating the device is dangerous.
The smell of rotten meat, which does not disappear after thorough cleaning and defrosting, may indicate that the drainage tube is completely clogged and water with bacteria has accumulated inside the housing. In this case, you may need to have the drain professionally cleaned by a technician.
It is also worth checking the condition of the lighting lamp. If it burns out and a short circuit occurs inside the base, a specific burning smell may appear. Replacing the lamp usually solves the problem, but if the smell remains, it is better to call a specialist.
⚠️ Warning: Repairing the electrical part of an LG refrigerator yourself may void the warranty and cause injury. If you smell a burning smell or see sparking, contact an authorized service center.
Is it possible to use chlorine-containing products to clean an LG refrigerator?
Using products with chlorine (for example, “Whiteness”) is highly not recommended. Chlorine has a very persistent and pungent odor, which the plastic of the refrigerator absorbs instantly. It will be almost impossible to ventilate it, and this smell will inevitably be transferred to the products. In addition, chlorine can damage plastic elements and seals.
How often should you change the carbon filter in an LG refrigerator?
In models where the carbon filter is replaced (usually it is located in the air circulation system), it is recommended to change it every 6 months or as needed if you feel that it has stopped working. In some models, the filter can be “regenerated” by heating it in the oven, but it is more effective to replace it with a new one.
Why does the smell return some time after cleaning?
If the smell returns, it means the source has not been completely eliminated. Most often, this is hidden mold in the seals, clogged drainage, or microparticles of food stuck in hard-to-reach ventilation areas. It is also possible that the smell has been absorbed into plastic parts (drawers, shelves), and they need to be soaked for a longer period.
Is it safe to use vinegar to wipe the internal walls?
Yes, a weak solution of table vinegar (9%) is safe for the plastic and rubber of LG refrigerators. It perfectly disinfects and neutralizes odors. The main thing is that after treating with vinegar, wipe the surfaces with a clean, damp cloth to remove the acid, and allow the camera to ventilate well before turning it on.
What to do if a smell appears in a new LG refrigerator?
The smell of new plastic is normal. To get rid of it, you need to wash the refrigerator with warm water and a mild detergent, wipe it dry and leave it with the doors open for a day in a ventilated area. You can spread lemon or activated carbon inside to speed up the process.
