Owners of combined refrigerators Samsung often face the need to accurately calibrate the microclimate inside the chambers to ensure the safety of food. The model RL28DBSI belongs to the class of devices with a system No Frost, which implies the absence of ice and requires a specific approach to adjusting thermostats. Correctly set parameters will not only extend the shelf life of food, but will also save energy by preventing the compressor from running idle.
Many users mistakenly believe that it is enough to simply turn a knob or press a button, however, the electronics of this model has its own nuances. Digital control allows you to set values accurate to a degree, but requires an understanding of the logic of the display panel. Incorrect installation can lead to melting ice cream or, conversely, freezing of vegetables in the main chamber.
This manual will help you understand the intricacies of operating your device. We will look at both standard modes and hidden functions available through button combinations. Understanding the principles of operation of the cooling system Samsung will allow you to become a real expert in controlling household appliances in your kitchen.
Control and display panel designThe control panel in the model RL28DBSI is usually located on the outside of the freezer door or on the upper end part. The display shows the current temperature values for the upper and lower compartments. It is important to distinguish between the indicators: they are often indicated by snowflake symbols for the freezer and a drop or sun symbol for the refrigerator compartment. Pressing the corresponding button activates the editing mode, which is indicated by flashing numbers on the screen.
Some modifications of this series use touch control, while others use physical buttons under the plastic. If you press the button but there is no response, the child lock feature may be activated. To disable it, you usually need to hold the lock button or key combination for 3-5 seconds. Locking the panel is a common reason why users cannot change settings, thinking that the electronics have broken down.
The indicator light also indicates the operating status. Lights up green - normal mode, flashes or lights up red - temperature alarm. The model RL28DBSI may have a compressor operation indicator that lights up during active freezing. Understanding these signals allows you to quickly respond to changes in the operation of the unit.
Adjusting the temperature in the refrigerator compartmentThe main compartment is designed for storing products that require cooling, but not freezing. The optimal value for this zone is considered to be from +3°C to +5°C. To change the settings, press the button responsible for the refrigerator compartment (often labeled as Fridge or has a corresponding icon). The numbers will begin to flash, and by successive presses you can select the desired value.
Remember that the system No Frost distributes cold air evenly, but the areas near the rear wall are always colder. Therefore, it is not recommended to place perishable foods close to the air flow outlet. If you set the temperature too low, for example +1°C, the vegetables in the lower drawers may lose moisture and wilt faster than usual.
☑️ Checking the refrigerator compartment settings
When loading a large number of products at room temperature, the electronics can temporarily increase the fan speed. During this period, there is no need to panic and change the settings: the system itself stabilizes the climate. If you are planning a party and need to quickly cool drinks, you can temporarily lower the value to +2°C, but do not forget to return it back.
Setting the freezing mode in freezerThe freezer in RL28DBSI is capable of maintaining temperatures down to -18°C and below. The button Freezeris used for control. Standard storage mode requires a setting of -18°C or -20°C. At this temperature, bacteria do not multiply, and products retain their properties for up to 12 months. The adjustment is carried out similarly to the refrigerator compartment: selecting a function, blinking the indicator, setting a value.
There is a function Super Freeze (Super Freeze), which is activated by a separate button or by long-holding the regulator. This mode causes the compressor to work continuously, reducing the temperature to -24°C or -25°C. This is necessary when loading a large volume of fresh products so that they quickly pass through the “crystallization point” and do not lose their tissue structure.
⚠️ Attention: Do not keep the Super Freeze mode on for longer than 24-48 hours unless necessary. Long-term operation at maximum power can lead to accelerated wear of the compressor and an increase in energy consumption by several times.
After fresh food has completely frozen (usually within a day), the function Super Freeze needs to be turned off so that the refrigerator returns to the normal mode of maintaining -18°C. In some firmware versions, shutdown occurs automatically after a specified period of time, but it is better to control this process manually.
Use of intelligent modes and functionsModern refrigerators Samsung are often equipped with a set (preset) of modes that optimize operation for specific situations. For example, mode Eco sets the temperature to about +7°C in the refrigerator compartment and -15°C in the freezer, which significantly reduces energy consumption. This is ideal for holidays or when the refrigerator is almost empty.
Mode Vacation (Vacation) works in a similar way, but with a nuance: in the refrigerator compartment the temperature rises to +15°C or +17°C to prevent the appearance of mold and odor when the door is closed, while the freezer continues to operate normally. This allows you not to defrost the lower sector and preserve supplies of meat or vegetables while you are away.
Hidden capabilities of electronics
In some models of the RL28DBSI series, it is possible to switch between operating modes of the inverter compressor through the service menu, but this requires an engineering combination of buttons and may void the warranty. It is not recommended to do this unless absolutely necessary.
It is also worth mentioning the fast freezing mode, which we have already touched upon, and the panel lock mode. The combination of these functions allows flexible control of the device. For example, by activating the lock, you can be sure that children will not accidentally change the settings while you are busy cooking.
Table of recommended temperatures for different productsTo maximize the benefits and taste, it is important to know where in the refrigerator and at what temperature it is best to store different types of products. Below is a reference table to help you optimize your space.
| Product type | Recommended zone | Optimal temperature (°C) | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat / Poultry | Bottom shelf (freshness zone) | +2... +4 | 1-2 days |
| Dairy products | Middle shelves (not against the wall) | +3... +5 | 3-5 days (after opening) |
| Vegetables and fruits | Bottom drawers (Crisp Box) | +5... +8 | 3-7 days |
| Ready meals | Upper shelves | +3... +6 | 24-48 hours |
Please note that the data is relevant for a properly functioning refrigerator. If you notice that products are deteriorating faster than the specified time limits even with the correct settings, you may need defrosting (although the No Frost system does not require this often) or checking the door seals.
Diagnostics of problems with temperature conditionsIf You have set the correct settings, but the refrigerator does not hold the temperature, you need to carry out initial diagnostics. First of all, check the tightness of the door. Gaps in the seal lead to a constant flow of warm air, and the compressor simply does not have time to pump out the heat. Also make sure that the ventilation holes inside the chambers are not blocked by food - air circulation is critical No Frost.
A common problem is evaporator freezing, even in systems with automatic defrosting. This can happen if the defrost sensor or heating element is faulty. In this case, the refrigerator may hum, but not generate cold. If “snow” or an ice crust appears on the back wall inside the refrigerator compartment, and the settings are correct, this is a signal of a malfunction.
⚠️ Attention: If you hear the relay clicking, but the compressor does not start, or vice versa, it runs without stopping, do not try to disassemble the back panel yourself. This could be life-threatening and will void your warranty.
In cases where the display shows an error code (for example, flashing lights or symbols like 88, E with a number), you must check the instructions. Frequently, flashing of both temperature indicators indicates defrosting after a long outage or power surge. In this case, you just need to wait a few hours until the system stabilizes.
Frequently asked questions (FAQ)
Why a Samsung refrigerator Is the RL28DBSI very noisy after adjusting the temperature?
An increase in noise immediately after changing the settings or turning on the Super Freeze mode is normal. The compressor and fans start working at maximum speed to quickly achieve the set parameters. If the noise does not subside after a few hours or is accompanied by vibration, check whether the refrigerator is level on the floor.
Is it possible to turn off the display so that it does not glow in the dark?
Most models of the RL28DBSI series do not have a function to completely turn off the display backlight in the standard menu, since it serves as an operation indicator. However, the brightness may decrease automatically some time after the last button press. Complete extinguishing is only possible when the Vacation mode is activated or the power is turned off.
What temperature should the freezer be for storing breast milk?
For long-term storage of breast milk, it is recommended to set the freezer temperature to -18°C or lower. With this mode, milk retains its properties for up to 6-12 months. It is important to use special sterile bags for freezing and sign the date of pumping.
What to do if the settings are reset after a power surge?
During a power surge, the controller's memory can be cleared and the refrigerator will return to factory settings. You need to manually reset the desired temperature settings. If surges occur frequently, it is recommended to connect the refrigerator through a surge protector or voltage stabilizer.
