Why there is an unpleasant smell in the refrigerator: 7 main reasons

Before dealing with the smell, you need to understand its nature. Here are the most common reasons:

• 🥦 Spoiled food - even a small piece of meat or fish forgotten on the back shelf can become a source of stench.
• 🧊 Drainage blockage holes - if the water does not drain, it stagnates and begins to rot.
• 🧽 Untimely cleaning —food debris, spilled liquids and stains on shelves accumulate bacteria.
• 🔄 Improper air circulation —if the refrigerator is overloaded, air does not circulate and odors stagnate.
• 🦠 Mold and mildew —often appear in the door seals or on the back wall.
• 🔌 Fan failure —in models with No Frost this leads to disruption of air exchange.
• 🧴 Chemical reactions —some products (for example, onions, garlic, fish) emit volatile compounds when stored nearby.

If the odor appears suddenly and does not disappear after cleaning, this may signal o technical malfunction. For example, in refrigerators Samsung RB37** or LG InstaView there is often a problem with a clogged drain tube. In this case, defrosting and cleaning the system will be required.

⚠️ Attention: If the smell is accompanied by constant noise or unstable operation of the compressor, do not try to clean the refrigerator yourself - this can be dangerous. Contact the service center.

Quick ways to remove the smell without defrosting

If the smell has just appeared and has not yet had time to be absorbed into the plastic, you can do without drastic measures. Here 5 express methodsthat will help in 1-2 hours:

1. Airing. Unplug the refrigerator, remove all food and leave the door open for 30-60 minutes. During this time, most of the smell will disappear.
2. Soda or activated carbon. Place on each shelf a small container of soda (2 tablespoons per glass of water) or place charcoal tablets in saucers.
3. Lemon or vinegar. Wipe all surfaces inside with a solution (1 tablespoon vinegar or lemon juice per 1 liter of water). This will kill bacteria and neutralize the odor.
4. Coffee or tea. Pour dry coffee powder or tea leaves into a bowl and place on the middle shelf for 12 hours.
5. Essential oils. Place 2-3 drops of citrus or tea tree oil on a cotton pad and place it on the top shelf.

These methods are suitable for fresh odorsthat have not yet been absorbed into sealants or plastic. If the problem is old, more serious measures will be required.

Deep cleaning of the refrigerator: step-by-step instructions

If the smell is persistent and does not disappear after express methods, it’s time to do general cleaning. Here is a detailed algorithm:

1. Turn off the refrigerator unplug and remove all products. If it's hot outside, put them in a cooler bag or wrap them in a towel with ice.
2. Remove all shelves and drawers. Wash them with warm water and detergent (for example, Fairy or Sanox). For stubborn stains, use baking soda.
3. Clean the drainage hole. It is located on the back wall (in models with a drip system) or under the vegetable drawer. Use a cotton swab or a special brush.
4. Treat the seals. Wipe them with a solution of vinegar (1:1 with water) - this will kill mold and bacteria.
5. Rinse the inner walls. Use a solution of water and vinegar or a specialized product (for example, Topperr 3101 for refrigerators).
6. Dry the refrigerator. Leave the door open for 2-3 hours or use a fan to speed up the process.

After cleaning, return the shelves to their place and turn on the refrigerator. To prevent the smell from returning, put a bag of silica gel on the bottom (you can take it from shoe boxes) or a special odor absorber (for example, Bork K700).

⚠️ Attention: Do not use chlorine-containing products or abrasive powders to clean the refrigerator. They can damage the plastic and leave toxic fumes that will be absorbed into the food.

Folk remedies vs professional chemistry: which is more effective?

Many housewives prefer natural odor absorbers, but sometimes they are powerless against persistent aromas. We compared the popular ones. methods:

Ionic air purifiers (for example, Xiaomi Mi Air Purifier Mini) can remove odors from the refrigerator in 1-2 hours, but only if the model supports closed spaces mode. However, this is an expensive solution, and it is advisable to use it only if there are constant problems with odors.

How to prevent odors: 8 food storage rules

The best way to combat odors is prevention. Follow these rules, and your refrigerator will always smell fresh:

• 📦 Store food in containers. Use airtight boxes for meat, fish, cheese and vegetables with a strong odor.
• 🧊 Defrost the refrigerator regularly. Even models No Frost need defrosting 1-2 times a year.
• 🗓️ Keep an eye on expiration dates. Check the contents of the refrigerator once a week and throw away expired products.
• 🧼 Wash the shelves once a month. It is enough to wipe them with a solution of soda or vinegar.
• 🍎 Separate foods into zones. Store meat and fish on the lower shelves, dairy products on the middle shelves, fruits and vegetables in special drawers.
• 🔄 Do not overload the refrigerator. There should be space between the products for air circulation.
• 🧴 Use odor absorbers. Silica gel, soda tablets or carbon filters will help maintain freshness.
• 🚫 Do not store in the refrigerator onions, garlic and spices - they absorb foreign odors and give off their own.

In refrigerators with system Total No Frost (for example, Bosch KAN92VI30R) the air circulates more actively, so odors spread faster. In such models, it is especially important to monitor the tightness of the packages.

What to do if the smell is absorbed into the plastic?

Sometimes the smell penetrates so deeply that ordinary cleaning does not help. In this case, try:

1. Hydrogen peroxide treatment. Wipe all plastic surfaces with a 3% solution, then rinse with water. Peroxide kills bacteria and whitens yellowed areas.
2. Using soda paste. Mix soda with water to a paste, apply to problem areas, leave for 15 minutes, then rinse.
3. Ozonation. If possible, use a household ozonizer (for example, AirComfort Clean 10). It destroys odor molecules at the chemical level.
4. Replacing the seal. If the rubber on the door is saturated with odor and cannot be washed, it will have to be replaced. For models Indesit or Atlant seals are sold at service centers.

If none of the methods helped, perhaps the smell comes from evaporator (in models with drip system) or fan (in No Frost). In this case, professional cleaning will be required.

⚠️ Attention: Do not use for cleaning plastic acetone, gasoline or solvents —they can damage the surface and make it porous, which will only increase the absorption of odors.

• 💦 Water accumulates in the refrigerator, and it smells rotten - this is a sign of a clogged drainage system or a broken evaporator.
• 🔥 A burning or plastic smell appears - this may indicate an overheating of the engine or a short circuit.

On average, the cost of diagnostics in service centers is from 1,500 to 3,000 rubles, and cleaning the drainage system costs 2,000–4,000 rubles, depending on the model. For example, cleaning Samsung RL38** usually cheaper than repair Liebherr Premium.
