Cold and Coldest modes in the refrigerator: decoding, setting and practical tips

Have you ever looked into the settings of your refrigerator and noticed mysterious inscriptions Cold and Coldest? These modes are found in models LG, Samsung, Indesit and other brands, but not all users understand their meaning. Meanwhile, the right choice between them directly affects the freshness of products, energy consumption and even the service life of equipment.

In this article we will analyze in detail:

• 🔍 what Cold and Coldest really mean (and why it’s not just “colder/more colder")
• 📊 how these modes are related to the actual temperatures in the chambers
• ⚡ how the choice of mode affects power consumption and compressor wear
• 🥦 which products require Cold, and which ones - Coldest
• ⚙️ step-by-step instructions for setting up (with photos of interfaces of popular models)

You will be surprised, but in 60% of cases users choose Coldest "just in case", although this is not only unnecessary, but also harmful to technology. Let's fix this!

1. What do Cold and Coldest mean? temperature

Let's start with the main thing: Cold And Coldest - This not absolute temperatures, A operating modes of the refrigeration chamber, which determine:

• 🌡️ Target temperature (range to which the system strives)
• ⏱️ Cooling intensity (how often the compressor turns on)
• ❄️ Cold distribution (uniformity across shelves)

In most modern refrigerators (for example, LG InstaView or Samsung RB Series) these modes correspond to the following parameters:

Critical detail: in Coldest mode, the freezer compartment cools more intensely than the refrigerator compartment! This is due to the fact that the main load goes to maintaining ultra-low temperatures in the freezer, and the refrigerator compartment is cooled “by the residual principle.”

🔹 Cold is the optimal mode for most users. It provides a balance between food safety and energy savings.

🔹 Coldest — temporary mode for emergency situations (for example, after defrosting or loading a large volume of warm food). Keeping it constantly means reducing the life of the compressor.

2. When to choose Cold and when to choose Coldest: practical cases

The choice of mode depends not on your preferences, but on current loading of the refrigerator and type of stored products. Here are clear recommendations:

✅Cold is suitable for:

• 🥛 Dairy products (kefir, sour cream, cottage cheese) - at +4°C they do not freeze and store consistency
• 🥚 Eggs (in the main compartment, not on the door!) - at +4...+5°C the yolk will not dry out
• 🍎 Fruits and vegetables (except tropical) - prevents the formation of condensation
• 🍗 Ready-made dishes (soups, main dishes) - enough for storage 2-3 days

❄️Coldest is necessary for:

• 🐟 Fresh fish and seafood - at +2°C the growth of bacteria slows down by 30%
• 🥩 Raw meat (if you do not plan to freeze) - safe storage up to 48 hours
• 🧀 Soft cheeses (Brie, Camembert) - prevents premature “ripening”
• 🍦 Ice cream in the refrigerator (if the freezer is full)

⚠️ Attention: Mode Coldest activates intense air circulation (in models with No Frost). This can lead to:

• 🌬️ Drying out of unpackaged products (greens, sliced fruits)
• 💧 Formation of excess condensation on the back wall (in drip systems)
• 🔊 Increased noise level (the compressor operates almost without pauses)

3. How to switch between modes: step-by-step instructions

The setup process depends on the refrigerator model. Let's look at the most common options:

📱 Refrigerators with a touch screen (LG Door-in-Door, Samsung Family Hub)

1. Press the button Temp Control or Fridge on the panel.
2. Use the arrows ↑/↓ to select between Cold/Coldest.
3. Confirm your choice with the button OK or Set.
4. Wait for the sound signal (in some models - the indicator blinks).

⚙️ Refrigerators with mechanical control (Indesit, Atlant)

1. Turn the temperature control (usually located inside the refrigerator compartment).
2. The marks 1-2 correspond to Cold, 3-4 — Coldest.
3. On models with separate controls for the refrigerator and freezer compartments, adjust both.

Make sure that the door is tightly closed|

Check the temperature after 6-8 hours|

Adjust the shelves for the new mode (for example, move the meat to the coldest zone)|

Clean the drainage hole (with a drip system)

-->

📌 Important: After changing the refrigerator mode required 4-6 hours to stabilize the temperature. Do not load warm foods in the first 2 hours!

⚠️ Attention: In refrigerators with inverter compressor (for example, Hitachi R-W660PUC6) switching to Coldest may cause a short-term shutdown of the display. This is normal - the system resets the cooling algorithms.

4.Coldest: when this mode is dangerous for a refrigerator

Continuous use Coldest is one of the main reasons for premature wear of the refrigerator. Here are the specific risks:

🔧 Technical consequences:

• 🔋 Compressor overload: in the mode Coldest it works on 80-90% of power, which reduces the resource by 20-30%
• ❄️ Evaporator icing: even in systems No Frost ice can form on hidden elements
• 💡 Overheating of the starting relay: in budget models (Beko CNK 335220) this is a common cause of breakdowns

💰 Economic losses:

According to laboratory data Roskachestvo, the refrigerator in the Coldest mode consumes 18-22% more electricity. For a family of 4 people this is:

• +120-150 kWh per year
• ≈ +500-700 rubles to bills (according to 2026 tariffs)

What happens to the compressor with constant Coldest?

During prolonged operation at maximum power, the oil in the compressor loses viscosity, which leads to increased piston friction. As a result, after 3-4 years extraneous noise may appear, and after 5-6 years - complete failure of the unit. Repairs cost 60-80% of the cost of a new refrigerator.

🔹 Exceptions: Mode Coldest is justified in the following cases:

• 🏝️ Heat outside the window (>30°C) + frequent opening doors
• 🍖 Loading a large volume of warm products (for example, after shopping)
• 🦠 Suspicion of food spoilage (unpleasant odor, mold)

5. Alternatives to Coldest: how to cool food without risking equipment

If you need to quickly cool food or maintain a low temperature, but do not want to use Coldest, use these methods:

🧊 Express cooling without Coldest:

• 🥶 Ice in containers: place ice packs on the shelves for 1-2 hours
• 🍷 Cold water: place a container of ice water on the top shelf (heat exchange will accelerate)
• 🔄 Ventilation: in models c Air Flow turn on forced circulation

⚙️ Setting up cooling zones (for multi-chamber refrigerators):

In refrigerators Liehberr and Bosch Serie 8 you can set the temperature by zone:

Menu → Temperature → Custom Cooling
Select a zone (for example, "FreshBox")
Set +1°C (instead of standard +4°C)

🔹 Advantage: Local cooling of only the desired zone without loading the entire system.

6. Common mistakes when using Cold and Coldest

Even experienced users make mistakes that lead to product damage or breakdowns. Here are the top 5 of them:

1. 🔄 Frequent switching of modes
   

   The compressor needs 6-8 hours to stabilize. If you change Cold to Coldest and back several times a day, this leads to:

   • Voltage surges in the motor windings
   • Uneven distribution of freon
2. 🥬 Storing vegetables in Coldest
   

   Cucumbers, tomatoes and peppers at +2°C lose vitamins and become “woolly”. The optimal temperature for them: +5...+7°C (use the compartment Fresh Zoneif there is one).

3. ❄️ Ignoring defrosting
   

   In Coldest mode, the ice in the freezer grows 2 times faster. Recommended defrosting frequency:

   • No Frost: once every 6 months
   • Drip system: once every 2-3 months

⚠️ Attention: If, after switching to Coldest the refrigerator does not cool below +5°C, this may indicate on:

• 🔌 Thermostat malfunction (check the error code on the display)
• 🧊 Freon leak (sign: the compressor runs without stopping)
• 🌡️ Clogging capillary tube (a common problem in refrigerators older than 7 years)

FAQ: Answers to frequently asked questions

❓ Is it possible to keep Coldest permanently if the refrigerator is new?

No, even in new models (Samsung RS50N3513SA, LG GC-B247JLUV) permanent Coldest reduces compressor life by 25-30%. Manufacturers recommend this mode for temporary use only (up to 48 hours). For long-term storage of food at low temperatures, it is better to set freezer mode to -24°C, and leave the refrigerator in the Cold.

❓ Why does the freezer work normally in the Coldest mode, but the refrigerator does not?

This is a feature of the cooling system. In Coldest mode, priority is given to the freezer compartment: up to 70% of the compressor power is spent on maintaining -24°C. The refrigerator compartment is cooled “according to the residual principle.” If you need intensive cooling of both compartments, use the mode Power Cool (if available) or temporarily reduce the freezer load.

❓ Which mode should you choose for storing baby food?

For most baby formulas and purees, the mode is optimal Cold (+4°C). The exception is milk formulas in open packaging: it is better to store them at +2...+3°C (temporary Coldest) for no longer than 24 hours. Always check the manufacturer's recommendations on the packaging!

❓ Why did the refrigerator begin to make noise after Coldest?

In Coldest mode, the compressor operates at maximum power, which leads to:

• 🔊 Increased vibration (especially in models with linear compressor)
• 💨 Increased fan speed (in systems No Frost)
• 🔧 Possible resonance with furniture (if the refrigerator is located close to the cabinet)

If the noise does not disappear after returning to mode Cold, check:

• Evenness of installation (use a level)
• Tightening of the compressor fastenings
• Absence of foreign objects near the ventilation racks

❓ Is it possible to store wine in Coldest mode?

No! Wine requires a stable temperature of +10...+14°C. In mode Coldest (+2°C):

• 🍷 Red wine loses its bouquet due to slower oxidation processes
• 🥂 Sparkling wines may lose gas (especially if the cork is imperfect)
• 🍾 White wines become overly “sour”

To store wine, use:

• Special wine refrigerators
• The lower shelves of the main refrigerator (there warmer)
• The compartment for vegetables (if the temperature there is regulated separately)

Now you know about the modes Cold more than 90% of users! Remember: the right choice not only keeps food fresh, but also prolongs the life of your refrigerator. If you have any doubts - start with the mode Coldest more than 90% of users! Remember, making the right choices not only keeps food fresh, but also extends the life of your refrigerator. If you have any doubts, start with the mode Cold and adjust according to the situation.
