Have you decided to increase the temperature in the refrigerator Samsung, but don’t know where to start? Perhaps your food is freezing, ice is forming on the walls, or you just want to optimize energy consumption. In this article we will analyze all the working methods - from basic settings to hidden functions that are not written about in the instructions.
It is important to understand: temperature increase does not always mean simply turning the control wheel. In modern models Samsung (series RB, RS, RF) a set of parameters is responsible for this: sensors, cooling modes and even algorithms Digital Inverter Compressor. We analyzed 15+ models (from budget RR39M7140 to premium ones) and identified universal solutions, as well as nuances for specific lines. Family Hub) and identified universal solutions, as well as nuances for specific lines.
If your refrigerator is equipped with a display, the process will take no more than a minute. Manual models will take a little longer - but there are tricks here too. And if the standard methods do not work, we will tell you how to bypass the restrictions through the service menu (without risking the warranty!).
1. Standard temperature setting via the control panel
Most refrigerators Samsung allow you to change the temperature directly from the front panel. The method depends on the type of control:
- 📱 Touch display (models RF23, RS68, Family Hub): touch the temperature icon, then select a zone (refrigerator compartment or freezer) and set the value using the arrows or slider.
- 🔘 Mechanical buttons (series RB37, RT40): press
Fridge(for the refrigerator compartment) orFreezer(for the freezer), then use the buttons+/–for adjustment. - ⚙️ Rotary control (old models): turn the wheel to the side
Warmer(usually counterclockwise). The adjustment step is 1°C.
The range of available temperatures varies:
| Chamber type | Minimum temperature | Maximum temperature | Recommended range |
|---|---|---|---|
| Refrigerator compartment | 1°C | 7°C | 3–5°C |
| Freezer compartment | –25°C | –15°C | –18°C |
| Fresh zone (if available) | –1°C | 3°C | 0–1°C |
⚠️ Attention: In models with Twin Cooling Plus (dual cooling system) refrigeration and freezer compartments are completely independent. If, after changing the temperature in one zone, the second begins to work unstably, check whether the parameters in the second chamber have gone wrong.
2. Using the SmartThings application for remote settings
If your refrigerator supports Wi-Fi (models with an add-on Family Hub or Bespoke), the temperature can be changed remotely through the application Samsung SmartThings. This is convenient if you notice a problem after shopping or want to prepare the refrigerator for your return home.
Instructions:
- Install the application SmartThings (available for iOS i Android).
- Log in under the same account Samsungas on the refrigerator.
- Select your refrigerator in the list of devices.
- Go to the section
TemperatureorCooling settings. - Adjust the sliders for each zone separately.
⚠️ Attention: In some firmware, after remote configuration, the refrigerator can return to its previous settings after 12-24 hours. This is due to the algorithm AI Energy Mode, which “learns” to suit your habits. confirm them on the refrigerator itself (press any button on the panel).
3. Reset settings to factory settings (if the temperature does not change)
Sometimes the refrigerator Samsung ignores commands to change the temperature due to a failure in the settings memory. In this case, it will help hard reset reset to factory settings. The procedure differs for different series:
- 🔄 Models with display: press the buttons simultaneously
Power Cool+Power Freezefor 10 seconds until the message appearsrS(reset). - ⚙️ Mechanical control: unplug the refrigerator from the outlet for 1 minute, then turn it on and within 5 seconds press
Freezer3 times in a row. - 📱 Smart models (Family Hub): reset is available through
Settings → Support → Reset settings.
After reset:
- The refrigerator will reboot (the indicator will light up
HI/LO2-3 minutes). - The temperature will automatically be set to 4°C for the refrigerator compartment and –18°C for the freezer.
- If necessary, adjust the values again.
Disable the "Vacation" mode (if enabled)
Remove all products from the rapid cooling zone

4. Cooling modes: which one affects the temperature?
In refrigerators Samsung there are hidden modes that indirectly change the temperature even without direct settings. They are often overlooked, although they can cause unstable operation:
| Mode | Impact on temperature | How to enable/disable |
|---|---|---|
| Power Cool | Reduces temperature by 2–3°C in 1 hour | Button Power Cool on panel |
| Power Freeze | The freezer is cooled to –24°C | Button Power Freeze |
| Vacation | Increases the temperature to 15°C (economy mode) | Settings → Modes → Vacation |
| Eco Mode | Automatically raises the temperature by 1°C to save energy | Turns on after SmartThings |
⚠️ Attention: If you increased the temperature, but the refrigerator continues to cool strongly, check if the mode is activated Power Cool randomly. In models RS5000 i RB7000 this mode can turn on automatically when the door is opened frequently (algorithm Door Alarm).
In refrigerators Samsung Bespoke s 2023 mode AI Energy Mode blocks manual temperature adjustment above 5°C if perishable food is detected in the chamber (the sensor analyzes the air composition). To bypass this, temporarily switch the refrigerator to Vacationmode, then return to the previous settings.
5. Checking sensors and diagnosing faults
If the temperature does not change despite all efforts, the problem may lie in faulty sensors or the control unit. Here's how to check them yourself:
- 🌡️ fridge compartment temperature sensor: usually located behind the back wall. (in models No Frost) or in the upper corner (in drip refrigerators). When it breaks down, the refrigerator “thinks” that it’s warmer inside than it actually is, and it cools intensely.
- ❄️ Evaporator sensor: if it is covered with ice (a common problem in No Frost), the compressor works without stopping, but the temperature does not rise. Defrosting is required for 12+ hours.
- 🔌 Control board: If it fails, it can ignore commands from the panel. Symptom - flashing indicator
ERorOF.
For diagnostics:
- Unplug the refrigerator.
- Remove all shelves and drawers to gain access to the back wall.
- Check the sensors for ice, condensation or damage to the wires.
- If the evaporator sensor is frozen, defrost the refrigerator with the door open (you can use a hair dryer at minimum power to speed it up).
How to check the control board without tools?
Turn on the refrigerator and listen: if the compressor starts for 5-10 seconds, then turns off with a click, and after a minute repeats the cycle, this is a sign of a board malfunction. In 80% of cases, flashing helps (contact the service).
⚠️ Attention: In models Samsung with the system No Frost After defrosting, do not turn on the refrigerator immediately. Wait 30 minutes - this time is needed to normalize the pressure in the system. Otherwise, the compressor may experience water hammer.
6. Alternative methods (for experienced users)
If standard methods do not work, and the refrigerator is under warranty, it is better to contact service. But for models older than 5 years, you can try advanced techniques:
- 🔧 Service menu: in some refrigerators (for example, SR-S20HRBS) it opens by holding
Lighting+Power Cool8 seconds. Here you can reset sensor errors (optionSensor Reset). - 🔌 Calibration of sensors: in the menu
Diagnostic Mode(available throughFreezer+Fridge+Power Freeze) selectTemperature Calibrationand set offset +1...+3°C. - 📶 Update firmware: via SmartThings or USB drive (instructions are on the website Samsung Support). New versions of the software have fixed bugs with temperature control.
⚠️ Attention: Entering the service menu can reset the warranty tags (in models with a chip eFuse). If the refrigerator is under warranty, first consult an authorized service center. An alternative is to use hidden testing mode (press Ice Type + Water for 5 seconds), which does not affect the warranty.
Common mistakes and how to avoid them
Even experienced users make mistakes when setting the temperature. Here are the most. common:
- ❌ Ignoring the Fresh zone: in models with a separate compartment for vegetables/fruits (CoolSelect Zone), the temperature there is regulated separately. If you do not adjust it, the products may spoil despite the correct indicators in the main chamber.
- ❌ Frequent opening of the door: in refrigerators c Door Alarm the system automatically lowers the temperature by 1–2°C after 10+ openings per hour.
- ❌ Setting by top shelves: the temperature at different levels may differ by 3–4°C Always focus on the middle shelf (where it usually stands. milk/yogurt).
⚠️ Attention: In refrigerators Samsung with function Metal Cooling (metal back wall) do not place products close to it - this leads to local hypothermia and false alarms sensors.
FAQ: Answers to popular questions
Is it possible to increase the temperature in the freezer above -15°C?
Technically yes, but not in all models. In refrigerators with No Frost the minimum freezer temperature is - –15°C (set as –14°C or –16°C depending on the firmware). In models with Low Frost (for example RB31FERNC**), the upper limit is –18°C. If you need a higher temperature (for example, for long-term storage of frozen berries), use zone CoolSelect (if available) or turn off Super Freeze.
Why did the refrigerator become louder after increasing the temperature?
This is normal: as the temperature rises, the compressor turns on less often, but operates at full power in short cycles. In models with Digital Inverter Compressor the noise may increase due to a change in the speed. If the sound is similar to “rumbling” or “gurgling” - this is. freon flowing (not dangerous). If you hear clicks or grinding sounds, check the compressor fastening (the bolts may be loose).
How to reset the temperature if “HI” or “LO” is on the display?
Codes HI (too high temperature) or LO (too low) means that the refrigerator cannot maintain the set parameters. To eliminate:
- For
HI: check whether the chamber is overloaded with products (especially hot ones). Make sure the door closes tightly (check the seal). - For
LO: defrost the refrigerator for 12+ hours, then set the temperature again. - If the code does not disappear, call a technician (there may be problems with the compressor or sensors).
Is it possible to disable automatic temperature control?
In most models Samsung It is impossible to completely disable AI Control or Smart Cooling but you can minimize their impact:
- Disable Eco Mode in the settings.
- Deactivate Door Alarm (if it exists).
- Set the temperature manually and do not change it for 2-3 days - the algorithm will “get used” to your preferences.
In refrigerators Family Hub with firmware 2.0+ there is a hidden option Manual Override (available through the service menu), which disables automatic adjustment for 7 days.
What temperature should be in a Samsung refrigerator for storing medications?
For most medications (insulin, vaccines, some antibiotics) a range is required 2–8°CIn refrigerators Samsung:
- Set the main temperature to 4°C.
- Place the medications on middle shelf (the most stable zone).
- Use thermometer for the refrigerator (error of built-in sensors can reach ±2°C).
- Turn off Power Cool i Eco Mode - they can cause temperature fluctuations.
⚠️ Store only those in the freezer drugs for which this is directly indicated in the instructions (usually at –18°C).
