Setting the temperature in the DEXP refrigerator: instructions with photos and tips

Refrigerators DEXP gained popularity due to the combination of affordable prices, modern design and functionality. However, even in simple models, setting the temperature can raise questions - especially if this is your first time encountering electronic control or a two-chamber system. An incorrectly selected mode leads to freezing of food, excessive energy consumption, or, conversely, insufficient cooling.

In this article we will look at how to correctly set the temperature in the refrigerator DEXP —from basic models with a mechanical regulator to advanced devices with a touch screen. You will learn which values ​​are considered optimal for different types of products, how to reset the settings to factory settings, and what to do if the refrigerator does not maintain the set temperature. And for owners of models with the system No Frost we have prepared separate recommendations for setting up ventilation and defrosting.

Before you start changing the parameters, check whether the refrigerator is connected to the network for at least 2-3 hours - this time is needed to stabilize the operation of the compressor. If you have just bought equipment, let it stand for 4-6 hours turned off (especially in the cold season) to avoid condensation on the internal walls.

Types of control panels in DEXP refrigerators

Models DEXP are equipped with three types of control panels, on which the process of setting the temperature depends. You can determine the type of panel you have by its appearance:

• 🔘 Mechanical — rotary control (usually located inside the refrigerator compartment or on the top panel outside). Used in budget models, for example DEXP RF-100 or RF-120.
• 🖥️ Electronic with buttons - digital display and touch/physical buttons (DEXP RF-180, RF-200). Allows you to set the temperature separately for the refrigerator and freezer compartments.
• ☁️ Touch with display —full screen with touch control (DEXP RF-300, series Premium). Supports additional functions like “Vacation” or “Super Freeze”.

In models with two compressors (for example DEXP RF-250D), the temperature setting for the refrigerator and freezer compartments is carried out independently. In single-compressor options, changing the mode in one zone can automatically adjust the parameters in another - this is normal and is provided for by the design.

If you are not sure about the type of panel you have, pay attention to the markings on the sticker inside the camera or in the device passport. Models with an index D at the end of the name (for example, RF-160D) are usually equipped with electronic control.

Optimal temperature conditions for the refrigerator and freezer compartments

The manufacturer DEXP recommends the following temperature ranges for different refrigerator zones:

Important: in DEXP refrigerators with the No Frost system, the temperature in the freezer can automatically increase to −15°C during the defrost cycle (every 8–12 hours). This is normal and does not require intervention.

For most users, the optimal choice will be:

• 🥛 Refrigerator compartment: +4°C —a balance between energy consumption and food safety.
• ❄️ Freezer compartment: −18°C —standard for long-term storage.

If your model has a freshness zone (usually a drawer with a separate lid), set it to +1°C —this will extend the shelf life of meat and fish to 5-7 days without freezing.

How to set the temperature on a mechanical panel

Mechanical regulators in refrigerators DEXP usually represent a rotary dial with numbers from 1 to 7 (less often up to 9). The higher the number, the colder. However, there is no direct connection to degrees: position “3” can correspond to +5°C in one model and +3°C in another.

Step-by-step instructions for models DEXP RF-100, RF-120, RF-140:

1. Find the regulator - it can be located on the top panel inside the chamber or on the front side refrigerator.
2. Turn the dial clockwise to increase the cold, counterclockwise to decrease it.
3. For the refrigerator compartment, set the position 2–3 (this is approximately +4°C...+5°C).
4. If the model has a separate regulator for the freezer compartment (for example, in DEXP RF-160), set 4–5 (corresponding to −18°C...−20°C).
5. Wait 6-8 hours until the temperature stabilizes, then check it with a thermometer.

In some budget models (for example, DEXP RF-90) the regulator is combined with the on/off button. In this case:

• 🔌 Press the button to turn on the refrigerator (the indicator will light up).
• 🔄 Turn the dial to adjust the temperature.

The products on the upper shelves are not covered with frost|There is no condensation on the back wall|The door closes tightly without cracks|The temperature in the freezer is below −16°C-->

If, after setting the refrigerator compartment, ice forms on the back wall, reduce the value by 1 position. In models without No Frost light frost is normal, but a thick layer of snow indicates too low a temperature.

Setting the temperature on an electronic panel with buttons

Electronic control panels in refrigerators DEXP (series RF-180, RF-200, RF-250) allow you to set the temperature with an accuracy of 1°C. The interface may differ, but the general principle is the same:

The main buttons you will need:

• 🔺 ▲/▼ or +/− — change the temperature.
• 🔄 Mode or Select — switch between refrigerator and freezer cameras.
• 🏠 Home or Set —saving settings.
• ❄️ Super Freeze —activating super freezing mode.

Step-by-step instructions:

1. Press the button Modeto select the chamber for setting (the indicator will light up on the display Fridge for refrigeration or Freezer for freezer).
2. Use the ▲/▼ buttons to set the desired value (for example, +4°C for the refrigerator compartment).
3. Press Setto save the setting.
4. Repeat steps 1–3 for the second compartment, if necessary.

On models with a display (for example, DEXP RF-300) the current temperature is constantly displayed. If the screen is inactive, touch any button to wake it up. Some devices support automatic regulation —in this case, the indicator will flash on the display Auto.

What to do if the buttons do not respond?

If the control panel does not respond to presses, try:

1. Unplug the refrigerator for 1-2 minutes, then turn it on again.

2. Check whether the child lock mode is activated (in some models it is turned on by long pressing on Set).

3. Inspect the panel cable - if it has come loose, repairs will be required.

In refrigerators DEXP with the function Holiday (Vacation) when it is activated, the refrigeration the chamber maintains a temperature of about +12°C, and the freezer operates in normal mode. This allows you to save energy during a long absence.

Setting features in DEXP refrigerators with No Frost

Models with the system No Frost (for example, DEXP RF-220NF, RF-280NF) automatically regulate circulation. air, which affects the distribution of temperature. In such refrigerators:

• 🌬️ The temperature is distributed more evenly, but the upper shelves are always slightly warmer than the lower ones (the difference is up to 2°C).
• ❄️ In the freezer the temperature may briefly rise to −15°C during defrosting (this is not breakdown!).
• 🔊 The fan works periodically, making a slight noise - this is normal.

For models with No Frost it is recommended:

• Install in the refrigerator compartment +3°C (and not +4°C), since the system itself maintains uniform cooling.
• Do not load the chamber with products more than 70% - this disrupts air circulation.
• Once every 6-12 months manual defrosting (despite No Frost) to remove ice from evaporator.

If your refrigerator DEXP has a function Air Flow (air flow), turn it on for faster cooling after loading a large amount of food. In some models, this option is activated automatically when the door is opened more than 30. seconds.

Common errors and their elimination

Even after correctly setting the temperature in the refrigerator DEXP may deviate from the norm. Let's look at typical problems and ways to solve them:

⚠️ Attention: If the refrigerator does not cool to the set temperature, check if the mode is turned on Demo (demo). In this case, the compressor operates in a gentle mode, and the display shows fictitious values. To turn it off. data-i="182">, hold the button Demo, hold the button Super Freeze 5–10 seconds.

If the refrigerator DEXP suddenly stops cooling, check:

• 🔌 Is it connected to the network (sometimes the plug falls out of the socket due to vibration of the compressor).
• 🌡️ Is the mode activated Holiday (in this case, the refrigerator compartment practically does not cool).
• 📊 Are the settings lost after a power surge (try resetting to factory settings).

In models with a display, errors may be displayed in the form of codes. Explanation for refrigerators DEXP:

• E1 - problem with the refrigerator compartment sensor.
• E2 - malfunction of the freezer compartment sensor.
• E3 - fan malfunction (for models with No Frost).
• E4 —short circuit or open circuit of the compressor.

⚠️ Attention: If, after resetting the settings or turning off the power, the refrigerator DEXP makes uncharacteristic sounds (knocking, grinding), do not turn it on again - this may indicate a jammed compressor.

Resetting to factory settings and calibration

If you have experimented with the modes and want to return the refrigerator DEXP to its original settings, perform a reset. The method depends on the type of control panel:

For mechanical ones. models:

• Turn the regulator to position 0 (or OFF).
• Disconnect the refrigerator from the mains for 5 minutes.
• Turn it on again and set the regulator to position 3 (recommended factory value).

For electronic models:

1. Press and hold the button Super Freeze (or Mode) for 10 seconds until a beep is heard.
2. The display will show inscription rSt (Reset) - release the button.
3. The refrigerator will reboot and the default values will be set:
   • Refrigerator compartment: +5°C
   • Freezer compartment: −18°C

In some models (for example, DEXP RF-300), the reset is performed through the menu:

Press sequentially:
Setting → Factory Reset → OK (hold 3 seconds)

After resetting, let run the refrigerator for 12–24 hours before making new changes. This time is needed to stabilize the operation of the compressor and sensors.

How to calibrate the temperature sensor?

If it seems to you that the refrigerator DEXP is showing the wrong temperature, you can perform calibration (only for electronic models):

1. Place the thermometer in a glass of water and leave it in the center of the refrigerator for 12 hours.

2. Compare the readings of the thermometer with the display.

3. If the difference is more than 2°C, contact the service department - self-calibration of sensors is not possible in DEXP refrigerators.

Tips for saving energy

The refrigerator DEXP is one of the main consumers of electricity in the house, but the right settings will help reduce costs by 10-15%. Here's what you can do:

• 🌿 Set the temperature in the refrigerator to +5°C (instead of +3°C). This is safe for most products and reduces the operating time of the compressor.
• ❄️ There is enough in the freezer −18°C —a further decrease in temperature increases energy consumption by 5-7% per degree.
• 🔌 Turn off function Super Freeze, if you do not freeze a large amount of food. In constant mode, it increases energy consumption by 20-25%.
• 🚪 Check the door seals - if they are worn out, the refrigerator loses up to 30% of the cold.

Additional measures:

• Do not place the refrigerator next to the stove, radiator or on the sunny side - this makes the compressor work harder.
• Defrost the freezer if the layer of ice exceeds 5 mm (even in models with No Frost).
• Do not store hot foods in the refrigerator - this increases the temperature inside and increases the load on the system.

In refrigerators DEXP with the function Eco Mode (economy mode) the compressor operation is automatically optimized. To activate it, press and hold the button Setting 3 seconds until the leaf icon 🌿 appears on the display.

FAQ: Frequently asked questions about setting the temperature in DEXP

Is it possible to set different temperatures on different shelves of the refrigerator?

No, in refrigerators DEXP the temperature is regulated uniformly for the entire chamber. However, natural convection leads to the fact that the upper shelves are 1-2°C warmer than the lower ones. For sensitive products (for example, meat), use the lower compartments.

Why does the DEXP refrigerator not restore the previous one after turning off the light? temperature?

In most models DEXP when the power is suddenly turned off, the settings are reset and the refrigerator turns on in factory mode (+5°C in the refrigerator, −18°C in the freezer). To avoid this, use an uninterruptible power supply (UPS) or manually restore the previous settings after turning it on.

How often do you need to check and adjust the temperature?

Under normal conditions, it is enough to check the temperature once every 1-2 months. Exceptions:

• After a long power outage.
• When the season changes (in summer, you may need to lower the temperature by 1°C).
• After defrosting or rearranging the refrigerator.

Use a separate thermometer for monitoring - the built-in sensors may go astray over time.

Is it possible to turn off the freezer if it is not needed?

In most models DEXP the freezer cannot be turned off - it works synchronously with the refrigerator. The exception is two-compressor models (for example, DEXP RF-250D), where the cameras are controlled independently. In this case, press the button Freezer Off (if available) or set the temperature to −8°C —the compressor will turn on less often.

What should you do if the DEXP refrigerator beeps and the temperature indicator flashes?

This is a signal that the temperature in one of the chambers is outside the normal range. Reasons and solutions:

• 🔌 The door is open or not closed tightly —check the seal and distribution of products (they can block closure).
• ❄️ Fan icing (for models with No Frost) - defrost the refrigerator for 12 hours.
• 🌡️ Sensor failure — try resetting the settings to factory settings. If the squeaking does not stop, contact the service.

In models DEXP the signal is reset automatically after the problem is fixed.
