Why an unpleasant odor appears in the refrigerator: the main reasons

Before dealing with the smell, you need to understand its source. Most often, the problem lies in:

• 🥛 Spoiled products —milk, meat, fish, cheeses, vegetables with a high water content (cucumbers, tomatoes), if stored improperly, begin to rot and release ammonia, hydrogen sulfide.
• 🦠 Bacteria and mold —a humid environment and food debris on the walls create ideal conditions for reproduction microorganisms. Mold may be hidden under rubber seals or in the drainage hole.
• 🧼 Insufficient hygiene - infrequent washing of shelves, containers and walls leads to the accumulation of fat, protein deposits and sauce residues.
• 🔌 Equipment malfunctions —if the refrigerator does not freeze well, food spoils faster. Also, the smell can come from burnt wiring or plastic parts (for example, in new models Samsung RB37A5200 or LG GA-B489).
• 🧀 Odor absorbersthat have not been replaced for years - over time, they themselves become a source of unpleasant odor.

An interesting fact: in refrigerators with a No Frost system, the smell can spread faster due to air circulation. And in models with drip defrosting water often accumulates in the pan, which leads to mold.

What not to do when eliminating odor

Many make mistakes that only aggravate the problem. This is what is strictly prohibited:

• 🧴 Use scented air fresheners (for example, Glaver or Ambi Pur). They only mask the smell, but do not eliminate its cause.

How to prevent odor: rules of prevention

The best way to deal with odor is to prevent its appearance. Follow these tips:

• 📅 Regular cleaning — wash the refrigerator at least once a month. For models No Frost wiping is enough, for drip models - complete defrosting every 3-6 months.
• 🥩 Proper storage of food:
  • Store meat and fish in airtight containers or vacuum bags.
  • Fruits and vegetables - in special boxes (humidity is regulated there).
  • Dairy products - only in closed containers.
• 🧊 Temperature control - there should be +2…+5°Cin the main chamber, in the freezer - -18°C. At higher temperatures, food spoils faster.
• 🔄 Ventilation —do not fill the refrigerator to capacity with food. Air should circulate between them.

Useful life hack: put it on the bottom of the refrigerator baking soda in an open package. It will absorb foreign odors and prevent the formation of mold. Change the soda every 1-2 months.

Features of caring for different types of refrigerators

Cleaning methods may vary depending on the type of refrigerator. Let's consider the nuances for the most popular systems.

Refrigerators with the No Frost system

In such models (Samsung RB30J3000, Indesit DF 4180, Bosch KGE39XW25R) no need to defrost the freezer manually the fan does this. However:

• Ventilation openings require regular cleaning of dust (once every 3 months).
• After washing, be sure to dry all surfaces - moisture can disrupt the operation of the system.
• Do not use sharp objects to remove ice (if it does appear) - this can damage the evaporator.

Refrigerators with a drip system

The main thing here is proper defrosting:

1. Turn off the refrigerator and take out all the food.
2. Wait until the ice melts naturally (not break it off with a knife!).
3. Rinse the drainage hole and pan (usually located at the bottom at the back).
4. Wipe all surfaces with a solution of soda or vinegar.

In models like Atlant MX 2824 or Birusa 130 after After defrosting, condensation may remain on the back wall - this is normal. It will evaporate after 1-2 hours of operation.

Built-in refrigerators

They have their own characteristics:

• Before washing mandatory turn off the water supply (if there is a dispenser).
• Do not use abrasive products - they can scratch the decorative panel.
• Check ventilation gaps (usually 2-3 cm on the sides). If they are clogged, the refrigerator overheats, which can cause an unpleasant odor.

⚠️ Attention: It is not recommended to use aggressive detergents in refrigerators with freshness zones (for example, Liebherr CBNes 4855). These compartments have a special antibacterial coating that can be damaged.

What to do if the smell remains after all the procedures

If you have tried everything, but the smell has not disappeared, perhaps the problem is deeper:

• 🔍 Mold in the drainage system - the tubes need to be flushed. Some models (Samsung RL34E) have a special brush for this.
• 🧲 Magnetic seals - if they come out, warm air gets into the cracks, which leads to condensation and odor. Check the tightness with a piece of paper: close the door if the sheet pulls out without effort, the seal needs to be replaced.
• 🔧 Compressor malfunction —if the smell is like burning, call a technician. Self-repair can be dangerous!

In rare cases, the smell may come from thermal insulation material (for example, in old models ZIL or MinskThe only thing that will help is replacing the seal or completely disinfecting the internal panels (this is done in service centers).
