A situation often arises when food in the refrigerator Samsung begins to freeze, and vegetables lose their structure and become watery. This is a sure sign that the current temperature setting is too low for the current operating conditions or chamber load volume. Equipment owners are faced with the need to change settings in order to maintain the freshness and taste of products.
Modern models of the South Korean brand are equipped with complex electronic control systems that can confuse an inexperienced user. In order to properly add temperature, that is, to make the air in the chambers warmer, you need to understand the logic of the operation of your specific interface. In some cases, one click is enough, in others you will need to enter the service menu or reset the settings.
In this article we will analyze in detail the algorithms of actions for different types of control panels, explain the difference between the concepts of “cooling” and “temperature”, and also consider the features of the operation of inverter compressors. You'll learn why your display may not respond to touch and how to avoid common calibration mistakes.
Understanding the interface: control panel and display
The first thing you need to do before changing settings is to identify the type of control panel on your device. Models Samsung are divided into several categories: with an external display on the door, with an internal panel (often hidden behind a decorative strip) and mechanical controls (in older or budget models). The sequence of actions directly depends on this.
If you have a model with an external display, you will see numbers indicating the current degree. It is important to understand: most refrigerators Samsung display exactly the current temperature inside the chamber, and not the desired one. However, in setting mode, the flashing numbers indicate the target value. To enter editing mode, you usually need to press and hold the button of the corresponding camera (Freezer or Fridge) for 3 seconds.
⚠️ Attention: If the “Lock” indicator is lit on the display or a padlock is shown, the panel is locked from accidental pressing by children. Before attempting to change the temperature, you must unlock the panel by holding the “Lock” button or a combination of buttons (often “Freezer” + “Fridge”) for 3-5 seconds.
For models with an internal panel located on the upper inner wall of the refrigerator compartment, the algorithm may differ. Touch buttons that respond to a light touch are often used here. In models such as Samsung RB30 or RB37, the setting is made by repeatedly pressing the “Fridge” button until the desired value appears. The numbers on the internal display may only show the set mode, not the actual temperature in real time.
Algorithm for increasing the temperature in the refrigerator compartment
The main task is to increase the degree value in the main compartment. The standard recommended temperature for storing prepared foods and drinks is +3...+4°C. If your temperature is set to +1°C or +2°C, food may freeze. To add temperaturefollow the logic of the interface: you need to select a larger numerical value.
Press the button Fridge (Refrigerator). The display will start flashing the current value. Each subsequent press of the same button will change the number. Unlike some other brands, where there are separate “+” and “-” buttons, Samsung often uses cycling. You need to press the button until the desired number appears (for example, +5°C or +6°C).

Fridgesequentially until the display shows the desired value (for example, +5 or +6). - ✅ Stop pressing the buttons and wait 5-7 seconds. The system will automatically save the new settings and the flashing will stop.
After confirming the settings, the compressor may not start immediately. The system Digital Inverter analyzes the load and current temperature before changing the operating mode. Don't panic if the engine noise doesn't change in the first 10-15 minutes. The electronics give a command to change the operation of the dampers and fan, which is quieter than starting the compressor.
☑️ Checking the refrigerator settings
Setting the freezer: nuances No Frost
The freezer requires special attention, since here the processes of moisture crystallization occur more intensely. The standard temperature for long-term storage of meat and semi-finished products is -18°C...-20°C. If you notice that the ice in the chamber has become too hard or, conversely, the food is covered with frost, adjustments may be required.
To change the parameters in the freezer, use the button Freezer. The operating principle is similar to the refrigerator compartment setting, but the range of values is negative. To increase the temperature (to make the mode “warmer”, for example, from -23°C to -18°C), you need to choose a number that is mathematically larger (smaller in absolute value). That is, -18 is warmer than -24.
⚠️ Attention: Do not set the temperature in the freezer above -15°C. At such values, the shelf life of products is sharply reduced, and some bacteria may remain active. The optimal range for domestic needs is from -18°C to -20°C.
Special mode - Fast Freeze (Fast freezing). If your indicator light is on, the refrigerator is running at maximum cooling, ignoring the degrees you set. To return to normal temperature, you must forcefully disable this mode. This is usually done by long (3 seconds) pressing the button Freezer until the corresponding indicator on the display disappears.
What are Power Cool and Power Freeze modes?
These are intensive cooling functions. Power Cool quickly lowers the temperature in the refrigerator compartment after loading food. Power Freeze does the same for the freezer. When these modes are active, manual temperature adjustment is temporarily disabled or ignored by the system until the task is completed. Disable them if you want to manually set the degrees.
Specifics of Side-by-Side and Multi-Zone models
Owners of large refrigerators Samsung Side-by-Side or models with a zone Flex Zone are faced with a more complex interface. There can be up to four independent temperature zones. Control is often carried out via a touch panel with additional zone selection buttons.
In such devices, it is important not to confuse the zone for which you are changing the settings. Button Select or Zone allows you to switch between the main refrigerator, freezer and additional chamber. The display will show which compartment is currently active for configuration. Be careful: by changing the parameter in the zone Flex Zone, you will not affect the main camera.
| Camera type | Recommended temperature | Setting range (approximate) | Button controls |
|---|---|---|---|
| Refrigerator (Fridge) | +3°C ... +4°C | +1°C ... +7°C | Fridge |
| Freezer (Freezer) | -19°C ... -20°C | -15°C ... -25°C | Freezer |
| Flex / Cool Select zone | 0°C (for meat/fish) | -23°C ... +3°C | Flex / Zone |
| Wine compartment | +10°C ... +12°C | +5°C ... +15°C | Wine / Select |
In models controlled via an app SmartThings (Wi-Fi module), configuration can be done remotely from a smartphone. This is convenient if the control panel on the refrigerator is located high or inconveniently. However, data synchronization may take up to 1-2 minutes. Make sure the refrigerator is connected to a Wi-Fi network.
Why the temperature does not change: diagnosing problems
There are situations when you have completed all the steps, but the desired result is not achieved. The display shows one thing, but the food freezes, or the numbers on the display do not change at all. This may indicate technical malfunctions or operating features of the system.
One of the common reasons is a malfunction of the temperature sensor. If the sensor “lies” and tells the controller that the chamber is +10°C, when in reality it is +1°C, the compressor will not turn off. In this case, a simple temperature setting through the panel will not help, since the system blindly executes commands based on false data.
- ❄️ Evaporator freezing: In No Frost systems, the damper that regulates the supply of cold air may get stuck in the open position due to ice. The cold will blow constantly, regardless of the settings.
- 🔌 Power surge: After a power outage, the electronics may freeze. A complete reset is required (see section below).
- 🛠️ Faulty defrost heating element: If the heating element is burned out, the ice does not melt, the damper is blocked, and the temperature drops below normal.
Also It is worth considering the “empty refrigerator” factor. If you have just turned on the device or loaded it with a small amount of food, the temperature may drop faster and below the set temperature. Empty space has no thermal inertia. Fill the chambers with bottles of water (approximately 60-70%) to stabilize the thermal conditions.
⚠️ Attention: If more than 24 hours have passed after changing the settings and the temperature has not stabilized, or error codes have appeared on the display (for example, “15C”, “22C”, “35C” - flashing numbers often indicate a fault code sensor), you need to contact a service center.
Resetting settings and rebooting electronics
Electronic control units of refrigerators Samsung, like any computers, can experience software failures. If the buttons do not respond, the display shows incorrect values, or the system ignores your commands, a forced reboot will help.
To perform this procedure, you do not need to reach inside with a screwdriver. It is enough to turn off the power to the device. Unplug the power cord from the outlet. This is a critically important point: simply turning off the button (if there is one) is not enough, you need to break the physical power circuit.
Reset algorithm:1. Disconnect the refrigerator from the power supply.
2. Wait at least 5-10 minutes (to discharge the capacitors).
3. Plug in the refrigerator.
4. Wait until the compressor starts and the display lights up.
5. Try setting the temperature again.
After switching on, the system may make clicking noises - this is when the relays and dampers are activated. During the first hour of operation, do not open the doors frequently, allow the system to cool down and calibrate the sensors. If after a reboot the problem with the inability to change the temperature persists, a hardware failure of the control board or display cable is likely.
Frequently asked questions (FAQ)
Why does a Samsung refrigerator show the temperature, but does not cool after setting?
This may be due to the compressor's protection interval. If you have just turned off the refrigerator or changed settings, the system may wait 5-10 minutes before starting the engine to avoid water hammer. Also check if the “Vacation” (Eco) mode is activated, which minimizes the operation of the unit.
Is it possible to set the temperature to +8°C or +10°C in the main chamber?
In most household models, the range is limited to +7°C. Above this value, food begins to spoil too quickly. If you need a temperature of +10°C...+14°C (for example, for storing chocolate or some fruits), use a special zone Cool Select or Flex Zoneif it is provided for by the design of your model.
What does flashing numbers on the display mean (for example, 18 or 22 is flashing)?
Flashing numbers on Samsung displays are most often not a temperature, but an error code. For example, a flashing “22” or “22C” often indicates an error in the refrigerator compartment temperature sensor. Flashing “15” or “15C” indicates a freezer sensor error. In this case, diagnostics of the sensors is required.
How often do you need to change the temperature settings in winter and summer?
Modern inverter refrigerators themselves adapt to the room temperature. However, if the refrigerator is located on an unheated balcony or next to a radiator, manual adjustment may be required. In summer, when it’s hot, you can slightly lower the temperature (make it colder), and in winter you can increase it (make it warmer), but usually this is not necessary if the equipment is in good working order.
