- 🧊 Mold in the drainage hole —if the refrigerator has a system No Frost, condensation flows into a special tank where fungus can grow.
- 🔌 Power outage —even a short shutdown leads to food spoilage and the appearance “ammonia” odor.
- 🧽 Improper cleaning —the use of aggressive detergents (for example, bleach) can leave a chemical odor that mixes with food.
Interesting fact: in refrigerators with ionization system (for example, Samsung Twin Cooling Plus or LG DoorCooling+) odors appear less frequently due to antibacterial air treatment. But even they require regular cleaning!

After washing the shelves you need dry thoroughlyotherwise condensation will remain on them, which will again become a source of odor. To speed up drying, use paper towels or leave the shelves in the sun (if they are not transparent, UV rays kill bacteria).
⚠️ Attention: Never wash the plastic parts of the refrigerator in dishwasher! High temperatures (60°C and above) can deform them and they will no longer fit. This applies even to models with. mark "washable in PMM" —manufacturers often mean only the top shelves.
How to prevent the appearance of odor in future?
The best way to combat odors is prevention. It is enough to follow a few simple rules, and the refrigerator will remain fresh for a long time.
- 📅 Cleaning schedule: Wash the refrigerator once a month (even if there is no smell). Use a solution of soda or vinegar.

- 🧊 Defrosting: In refrigerators with drip system defrost the freezer every 3 months, once every 6 months. No Frost - once every 6 months.
- 🌿 Natural absorbers: Keep the open pack in the refrigerator soda, lemon peel or a bag of rice - they absorb foreign odors.
- 🔍 Temperature control: The optimal temperature in the main chamber is
+4°C, in the freezer --18°C. At higher values, food spoils. faster.
