Setting the temperature in the Samsung No Frost refrigerator: instructions for two-chamber models

Two-chamber refrigerators Samsung with the system No Frost are distinguished by ease of use and uniform cooling of products. However, even this technique requires the correct setting of temperature conditions - not only the safety of food, but also energy consumption, as well as the service life of the compressor, depend on this. If you have just purchased a model Samsung RB37J5230SA, RT38K6030S8 or a similar one, or simply want to optimize the operation of an old refrigerator, these instructions will help you understand all the nuances.

Unlike drip systems, where setting often comes down to turning a mechanical regulator, electronic control No Frost offers more possibilities - but also more questions. How to set the temperature in each chamber correctly? What values ​​are considered optimal for the freezer and refrigerator compartment? What to do if the refrigerator Samsung does not maintain the set mode? Answers to these and other questions - with step-by-step photos, tables of recommended values and analysis of typical errors.

Why is it important to correctly set the temperature in No Frost

System No Frost (translated as “no frost”) automatically removes moisture and prevents ice formation, but this does not mean that you can ignore the settings. An incorrectly selected mode leads to:

• 🥦 Food spoilage: if the temperature in the refrigerator compartment is too high, the milk sours faster and the meat becomes moldy. In the freezer, if there is insufficient cooling, ice crystals form, destroying the structure of the food.
• ⚡ Increased energy consumption: if the refrigerator operates at maximum power unnecessarily, electricity bills will increase by 15-20%.
• ❄️ Excessive load on the compressor: constant operation extreme modes reduces the service life of equipment. In models Samsung with an inverter compressor, this is especially critical.
• 💧 Education condensate: if the temperature difference between the chambers is incorrect, moisture may appear on the walls, despite the No Frost system.

The manufacturer states that the optimal temperature for the refrigerator compartment is +3…+5°C, and for the freezer - -18°C. However, these values may vary depending on:

• 📦 The load of the chambers (a full refrigerator takes longer to cool).
• 🌡️ Room temperatures (in hot weather the compressor works more intensely).
• 🍎 The type of stored food (for example, for greens need a temperature closer to +7°C).

Where the controls are located in Samsung No Frost refrigerators

Depending on the model Samsung the control panel may be located:

• 📱 On the outside of the door (for example, in series RB and RT with a display).
• 🔄 Inside the refrigerator compartment (mechanical regulators in budget models).
• 🖥️ On the top panel (touch buttons in premium lines, such as Family Hub).

Consider the two most common options:

1. Electronic control with display (models RB, RS, RT)

In refrigerators Samsung RB37J5230SA, RT38K6030S8 and similar settings temperature is carried out through the touch panel or buttons Fridge (refrigerator compartment) and Freezer (freezer compartment). Interface example:

• 🔹 Button Fridge —adjustment of the refrigerator compartment (usually from +1°C to +7°C).
• ❄️ Button Freezer — adjustment of the freezer compartment (from -14°C to -25°C).
• 🔄 Button Power Cool / Power Freeze —accelerated cooling (turns on for 2-3 hours).
• 🔕 Button Vacation —Vacation mode (turns off the refrigerator compartment, leaving the freezer to work).

2. Mechanical control (models with rotary controls)

In simpler models (for example, Samsung RT28K4030S8), instead of a display, rotary switches with numbers from 1 to 7 are used. The rule here is:

• 1–2 — minimal cooling (suitable for winter or light load).
• 3–4 — optimal mode for most conditions.
• 5–7 —maximum cooling (needed in hot weather or when fully loaded).

Step-by-step instructions: how to set the temperature

Let's consider the process using the example of a popular model Samsung RB37J5230SA with electronic control. For other models, the steps are similar, but the location of the buttons may differ.

1. Turning on the refrigerator and resetting the settings

If the refrigerator is new or after defrosting, perform a reset:

1. Connect the refrigerator to the power supply and wait until it starts (a flashing indication appears on the display).
2. Press and hold the button Power Cool + Power Freeze for 5 seconds until you hear a beep.
3. After the reset, the display will show the factory settings: +3°C for the refrigerator compartment and -18°C for the freezer.

2. Setting the refrigerator compartment

To change the temperature:

1. Press the button Fridge once - the current value will flash on the display.
2. Use the buttons + or - set the desired temperature (recommended value - +3…+4°C).
3. Wait 5 seconds - the setting will be saved automatically.

3. Setting the freezer compartment

Similar to the refrigerator compartment:

1. Press Freezer - the current temperature will start blink.
2. Set the value from -16°C to -20°C (optimal -18°C).
3. For quick freezing (for example, when loading a large number of products) activate Power Freeze to 2–3 hours.

Make sure the doors are tightly closed|

Check the temperature after 6-8 hours with a thermometer|

4. Additional modes

In refrigerators Samsung with the system No Frost special functions are available:

Optimal temperature conditions for different products

Even in a refrigerator with No Frost products require different storage conditions. The table below contains recommendations for the most common categories:

In Samsung refrigerators with a freshness zone (for example, FlexZone in models RF23) the temperature is regulated separately - usually in range 0…+3°C. This zone is ideal for meat, fish and delicacies.

For the freezer, general rules apply:

• ❄️ Quick freezing (-24…-30°C) - for fresh berries, herbs, meat (no longer than 2-3 hours).
• ⏳ Long-term storage (-18°C) - optimal for most products (up to 12 months).
• 🍦 Ice cream and semi-finished products — -16…-18°C.

What to do if the products freeze in the refrigerator compartment?

If ice appears on the products in the refrigerator compartment or they are freezing, check:

1. Location of products —do not place them close to the back wall where the evaporator is located.

2. Temperature mode —reduce the value to +4…+5°C.

3. Loading the chamber —if The refrigerator is almost empty, the compressor is working harder. Add several bottles of water to stabilize the temperature.

4. Door closure tightness - a worn seal can lead to uneven cooling.

Typical errors when setting the temperature

Many users make the same mistakes, which lead to product damage or breakdowns. Let's look at the most common ones:

⚠️ Attention: If, after changing the settings, the refrigerator Samsung does not cool to the set temperature within 24 hours, this may indicate a sensor malfunction or a freon leak. In this case, diagnostics from a service center is required.

1. Setting maximum cooling “just in case”

Many people believe that the colder the better. However:

• 🥬 When vegetables and fruits +1°C lose vitamins and become tasteless.
• ⚡ The compressor works without interruptions, which leads to increased wear.
• 💰 Electricity consumption increases by 20–30%.

2. Ignoring the mode Vacation during a long absence

If you are leaving for 1-2 weeks, do not turn off the refrigerator completely - this will lead to defrosting of the freezer and the formation of mold. Instead:

1. Activate the mode Vacation (turns off the refrigerator compartment, the freezer remains working).
2. Remove all perishable foods.
3. Leave the refrigerator door slightly open (for example, insert it between the seal and a wooden spatula with a body).

3. Frequent opening of the door in the heat

In the summer, when the temperature in the kitchen exceeds +30°C, each opening of the door causes the compressor to work at the limit. To reduce the load:

• 🕒 Plan loading/unloading food in advance.
• 🚪 Do not keep the door open for more than 10-15 seconds.
• 🌡️ On hot days, increase the temperature in the refrigerator compartment by 1°C (for example, from +3°C to +4°C).

4. Storing hot foods

Placing pots of hot soup or pans in the refrigerator leads to:

• 🔥 A sharp increase in temperature inside the chamber.
• ❄️ Formation of condensation and ice (even in No Frost).
• 🛠️ Compressor overload.

Cool food to room temperature before putting it in the refrigerator.

How to check if the refrigerator is working properly

Even if you set the temperature according to the instructions, the actual values may differ. Here's how to check them:

1. Using a thermometer

Place an outdoor thermometer (or a special one for refrigerators) in a glass of water and leave it on the middle shelf of the refrigerator for 6-8 hours. specified:

• 🟢 Norm: deviation no more ±1°C.
• 🟡 Acceptable: deviation ±2°C (adjustment may be needed).
• 🔴 Critical: deviation more ±3°C (diagnostics required).

2. Checking uniformity of cooling

Place thermometers on different shelves:

• 📊 Top shelf —usually the warmest (on 1–2°C above average).
• 📊 Middle shelf —reference zone.
• 📊 Bottom shelf —the coldest (maybe 1°C below average).
• 🥬 Vegetable tray —the temperature here is 2-3°C higher than on the middle shelf.

⚠️ Attention: In refrigerators Samsung with system Twin Cooling Plus (double fan) the temperature difference between the shelves is minimal. If you notice strong differences, this may indicate a malfunction of one of the fans.

3. Leak tightness test

The tightness of the door is checked as follows:

1. Take a sheet of A4 paper.
2. Place it between the seal and the body of the refrigerator.
3. Close the door and try to pull out the sheet.

Result:

• 🟢 Sheet is pulled out with force - the seal is working.
• 🔴 The sheet comes out easily - the seal needs to be replaced.

What to do if the Samsung No Frost refrigerator does not keep the temperature

If, after setting, the temperature in the chambers does not correspond to the set one, the reasons may be either incorrect operation or malfunctions. Let's figure it out in order.

1. Software failures

Sometimes the electronic board of the refrigerator Samsung fails. To reset the settings:

1. Unplug the refrigerator for 10-15 minutes.
2. Turn it back on and wait for initialization (the factory temperature will appear on the display).
3. Set the parameters again.

2. Contamination of the No Frost system

Although No Frost does not require defrosting, dust and grease can clog the ventilation vents. holes. Signs:

• 🌀 The fan is louder than usual.
• ❄️ Ice appears on the back wall of the freezer.
• 🌡️ The temperature in the refrigerator compartment rises.

Solution:

1. Unplug the refrigerator.
2. Remove all products and shelves.
3. Clean the ventilation grilles with a soft brush (do not use metal objects!).
4. Wash the back wall freezer with warm water and vinegar (1:1).

3. Malfunction of sensors or compressor

If after all the manipulations the problem remains, hardware failure is possible:

⚠️ Attention: If your refrigerator Samsung is under warranty, do not try to repair it yourself. Contact an authorized service center - the list can be found on the official website Samsung by model number.
