When faced with a pungent or musty smell in an LG refrigerator, owners often panic, believing that the equipment is out of order. However, in most cases, the reason lies not in a compressor failure or freon leak, but in a banal violation of operating rules or hygiene. Modern units, especially models with the No Frostsystem, are more complex than their predecessors and require a special approach to maintenance.
In this article we will look in detail at why the LG refrigerator stinks, and how to return freshness to the food storage room without calling a technician. You will learn about hidden places where bacteria accumulate, the peculiarities of the drainage system and chemical reactions that can occur inside the device if food is stored improperly.
Ignoring the problem can lead not only to spoilage of food, but also to the appearance of mold on the seals and internal walls, which will require more serious intervention. LG Electronics provides for various filtration systems, but they do not are omnipotent and need your help.
Primary diagnosis: products or equipment?
The first step should always be a thorough audit of the contents of the cameras. Often the source of the smell turns out to be a simply forgotten piece of cheese or spilled milk that has flowed into hard-to-reach corners of the shelves. The smell of rotting organic matter can permeate plastic interior elements in a matter of hours, creating a lasting aroma.
If the problem persists after completely unloading the food and washing the shelves, then the problem is in the refrigerator itself. In LG models with technology Total No Frost air circulation is forced, which can spread the smell throughout the entire volume if it originates in one of the compartments. It is important to check whether a foreign object has entered the ventilation openings.
⚠️ Attention! If you smell burning, rubber or plastic, immediately unplug your refrigerator. This may indicate overheating of the wiring or melting of the insulation, which requires urgent intervention by an electrician.
There is a common misconception that a new refrigerator should not smell of anything. In fact, the smell of new plastic is normal, but it should dissipate in a couple of days. If the smell of new equipment is sour or rotten, this is a defective seal or a violation of warehouse storage conditions.
Problems of the drainage system in No Frost models
One of the most common reasons why an LG refrigerator stinks is a clogged condensate drainage system. During operation, moisture forms on the evaporator, which must flow into a special tray above the compressor and evaporate. If the drainage hole becomes clogged with crumbs or mold, the water stagnates and begins to rot.
To clean the channel, it is often enough to use a special soft brush or a medical bulb with warm water. You need to move the tool carefully so as not to pierce the thin walls of the tube and damage the elements of the defrost system defrost.
In some cases, bacteria settle directly in the water collection pan, which is located above the motor-compressor. It is difficult to get to and often requires partial disassembly of the rear wall of the refrigerator compartment. The water that stagnates there turns into a foul-smelling slurry, the smell from which is drawn by the fan into the chamber.
☑️ Cleaning the LG drainage
Regular prevention of blockages will help avoid the appearance of a persistent smell of dampness and mustiness. If the water does not go away after flushing, it is possible that the ice plug has frozen deeper in the channel, and the unit will need to be defrosted within 24 hours.
Mold on seals and in hidden cavities
A rubber door seal is an ideal environment for the proliferation of microorganisms. Food debris, juice and moisture often accumulate in the folds of the cuff. If your LG refrigerator smells like dampness, carefully inspect the joints between the rubber and the metal body.
Mold can penetrate deep into the pores of the rubber, and simply wiping it with a rag will not help. It is necessary to use special antibacterial agents or a vinegar solution. It is important to treat not only the visible part, but also the area where the door meets the body.
In models with a zone Fresh Zone or zero chamber, the humidity can be increased, which accelerates the growth of mold in the corners of drawers and under the supports. Remove all plastic inserts and check the space under them - black dots of fungus are often found there.
| Localization location | Type of odor | Probable cause | Elimination method |
|---|---|---|---|
| Sealant doors | Musty, moldy | Fungus deposits in folds | Treatment with vinegar or special agent |
| Drainage hole | Sour, waste | Clogged, stagnant water | Cleaning with a brush, spilling water |
| Evaporator (behind the wall) | Rotten | Frozen products in the system | Defrost 24 hours, cleaning the master |
| Tray above the compressor | Swampy | Rotting of stagnant condensate | Access through the back panel, washing |
If mold has affected the rubber structure and after After cleaning, the smell returns, the seal may have to be replaced. The porous structure of old rubber becomes a breeding ground for bacteria that cannot be gotten rid of by washing.
Malfunctions of the defrost and evaporator system
A more serious reason why the LG refrigerator stinks is associated with a breakdown of the automatic defrost system. If the evaporator heating element, thermostat or timer fails, an excessive layer of ice will build up on the radiator. When periodically thawed, this ice, together with dust and bacteria, gives off an unpleasant odor.
In some cases, small pieces of food (for example, peas or lettuce leaves) may get into the ventilation system, which are drawn in by the air flow. Being on the fan blades or evaporator, they rot, and the smell spreads throughout the chamber every time the motor is turned on.
⚠️ Attention! Self-disassembly of the rear panel to access the evaporator may damage fragile plastic elements or break the tightness of the circuit. If you are not confident in your abilities, it is better to call a specialist.
This problem can be diagnosed by the presence of a “fur coat” on the back wall or uneven cooling. If the refrigerator stops freezing and an odor appears, the system most likely requires repair. No Frost.
Can an ozonizer be used?
Ozonizers are effective in neutralizing odors, but they do not eliminate the cause. Use them as an aid after mechanical cleaning. Prolonged exposure to ozone on rubber seals can shorten their service life.
Chemical absorbers and traditional methods
After eliminating the physical cause of the odor, it is necessary to neutralize the remaining aromas. Modern LG refrigerators are often equipped with carbon filters Hygiene Fresh+ or similar air purification systems. Check the service life of such a filter - if it is exhausted, it needs to be replaced.
If there is no standard filter or it cannot cope, you can use folk remedies. Activated carbon, soda, ground coffee or special odor absorbers from the pet store perfectly adsorb odor molecules. Place them on the shelves for 2-3 days.
To wash the internal surfaces, use a solution of baking soda (1 tablespoon per liter of water) or a weak solution of vinegar. It is not recommended to use chlorine-containing products, as they can damage the plastic and leave their own pungent odor, which will be difficult to remove.
If the source of the odor (for example, rotting food in the crack) is not removed, no tablets will not help.
Prevention and operating rules
To ensure that the question “why does the LG refrigerator stink” no longer bother you, you should follow simple rules for storing food. All liquid and odorous products must be covered or packaged in airtight containers. This will prevent aromas from mixing and particles from entering the ventilation.
Regularly, at least once a month, inspect your inventory and wipe the shelves with a damp cloth. Do not place hot foods inside the chamber - this creates excess condensation, which promotes the growth of bacteria.
Make sure the door is in good working order: if the seal does not fit tightly, warm air enters the chamber, which leads to more intensive operation of the compressor and the formation of excess moisture. Wipe the seal and check for cracks.
Compliance with the temperature regime is also important. If the refrigerator is too warm, food will spoil faster. Check the thermostat settings and make sure that they comply with the manufacturer's recommendations for the current season.
When you need to call a technician
There are situations when self-cleaning does not help. If after complete defrosting, disinfection and replacement of filters the smell persists, the problem may be inside the foamed housing or in the refrigerant circulation system (although freon itself has no smell, when the compressor winding burns, the smell will be specific).
Also, professional help is needed if the smell is accompanied by a change in the operation of the refrigerator: it begins to hum louder, does not turn off longer, or freezes worse. These are signs of a mechanical or electrical malfunction.
The technician will be able to conduct a full diagnosis, disassemble the unit, clean the air ducts and check the electrical circuits. Sometimes it is necessary to replace the evaporator or restore the seal, which cannot be done at home.
How often should you wash an LG refrigerator?
It is recommended to carry out a general cleaning of the refrigerator with defrosting (if there is No Frost) or thorough washing (for No Frost) at least once every 3-4 months. This will help prevent the accumulation of bacteria and the appearance of persistent odors.
Is it possible to wash the inside of the refrigerator with water?
Yes, you can and should, but only with a well-wrung out cloth. You cannot pour water in buckets into the chamber, as it can get into electrical contacts or behind the insulation, which will cause a short circuit or corrosion.
Why does the refrigerator smell like sewer?
The smell of sewer usually indicates a serious blockage of the drainage channel, where water has stagnated and the processes of rotting organic matter have begun. Also, the cause may be the entry of a foreign object (for example, a piece of sponge or food) into the drainage system.
Is the smell from the refrigerator harmful to health?
Yes, a constant unpleasant odor indicates the presence of bacteria, mold and their waste products in the air. Inhaling mold spores and volatile decay compounds can cause allergies, headaches and eating disorders.
