Modern household appliances require careful attention to basic operating parameters to ensure long service life of the products. Refrigeration equipment of the brand DEXP, presented in a wide range of models, is equipped with various climate control systems inside the chambers. Proper temperature setting is not just a matter of comfort, but a critical aspect of preserving the nutritional value of the contents and preventing the growth of bacteria.
Owners are often faced with a situation where standard factory settings do not meet current needs or external conditions, for example, in the summer heat or when the shelves are fully loaded. Temperature balance between the refrigerator and freezer compartments must be strictly observed to The compressor was not working properly. In this article, we will analyze in detail the setting algorithms for different types of control, from mechanical regulators to advanced electronic displays.
Understanding the principles of operation of your model will allow you to avoid common mistakes, such as the formation of excessive ice or, conversely, insufficient cooling. We will look at the nuances of system operation No Frost and static cooling, since approaches to their calibration may vary. Proper setup today means saving energy tomorrow.
Determining the type of control system of your model
The first step before starting any manipulations is to identify the control interface. Models DEXP can be equipped with both classic mechanical thermostats and electronic panels with digital display. Mechanical control is usually represented by a rotary knob inside the refrigerator compartment, marked with numbers from 1 to 5 or 7. In this case temperature adjustment it is done intuitively: turning clockwise increases cooling.
Electronic control systems located on the outer door or inside the chamber provide more precise control. Here you operate in specific degrees Celsius, which eliminates guesswork. Entering setup mode often requires a long press of a button or key combination. It is important to distinguish between models with a display and models with LED indicators, where modes are indicated by flashing lights.
⚠️ Attention: Before actively setting up the electronic panel, make sure that the refrigerator door is tightly closed. Some models DEXP block changes to settings if the door sensor detects a loose fit to avoid accidental activation of functions.
If you are not sure about the type of control, refer to the technical documentation or find the model sticker (nameplate), usually located inside the camera or on the back wall of the case. Knowing the exact model will help you find specific instructions if standard methods don't work. Electronics are sensitive to power surges, so it is better to set up when the network is stable.
Setting up a mechanical thermostat
In models with mechanical control, the setup process is as simplified as possible, but requires an understanding of the logic of the thermostat. The regulator is a device that opens the electrical circuit when the set temperature is reached. The numbers on the scale do not mean degrees, but indicate the cooling strength: the higher the number, the lower the temperature inside the chamber.
To set the optimal mode, turn the knob to value 3 or 4. This is considered the middle position, suitable for most situations. If the room is very hot or you have just loaded a large amount of warm food, you can temporarily increase the power to 5-6. However, it is not recommended to constantly keep the regulator at maximum, as this leads to freezing of the evaporator and increased load on the compressor.
There are nuances that should be taken into account when operating mechanical systems. For example, in winter, when the apartment is cool, the power can be reduced to 2-3. Sharp changes in values on the regulator are undesirable - change the position of the knob smoothly. After each change of position, give the system 4-6 hours to stabilize the temperature background before assessing the result.
- ❄️ Position Min (1-2): Recommended for the winter period or with a small load of products.
- ❄️ Med position (3-4): Standard operating mode for daily use under normal conditions.
- ❄️ Max position (5-7): Intensive cooling mode for quick freezing or hot weather.
Temperature adjustment on the electronic display
Electronic control in refrigerators DEXP allows you to set the temperature with an accuracy of one degree. Typically, the panel has separate buttons or touch zones for the refrigerator (Fridge) and freezer (Freezer) compartments. To change a value, you must press the corresponding button - the numbers will begin to flash, signaling that they are ready for entry. Use the arrow buttons + and - to select the desired value.
The optimal temperature for the refrigerator compartment is considered to be the range from +3°C to +5°C. At these values, products remain fresh for as long as possible without freezing at the back wall. For the freezer, the standard is -18°C. Reducing the temperature below -20°C usually has no practical meaning for household storage and only increases energy consumption, although it allows you to quickly freeze fresh food in the mode Super Freeze.
☑️ Checklist for setting up the electronic module
Some advanced models are equipped with a Eco or Smartmode, which automatically selects the optimal parameters depending on the frequency of door openings and room temperature. Activating this mode often disables manual adjustment, transferring control to the board's algorithms. If you need a specific temperature, make sure that automatic energy saving modes are turned off.
| Storage area | Recommended temperature | Acceptable range | Impact on food |
|---|---|---|---|
| Refrigeration chamber | +4°C | +2°C.. +5°C | Slowing the growth of bacteria |
| Freezer compartment | -18°C | -16°C.. -24°C | Complete stop of biological processes |
| Freshness zone (Zero) | 0°C | 0°C.. +1°C | Preservation of vitamins in meat and fish |
| Door shelves | +6°C.. +8°C | +5°C.. +10°C | Least cold zone for sauces |
Using the quick freeze mode
The quick freeze function (Super Freeze or Quick Freeze) is A powerful tool, but it must be used with caution. When this mode is activated, the refrigerator compressor DEXP works continuously, ignoring the readings of temperature sensors, until the temperature in the freezer drops to extremely low values (usually about -24°C..-26°C). This allows you to quickly freeze large volumes of fresh products, preserving their structure and cell tissue juice.
This mode should be turned on 3-4 hours before loading the products or immediately after placing them in the chamber, depending on the instructions for the specific model. The function automatically turns off after a certain time (usually 24-48 hours) or after reaching the target temperature. Long-term use of the fast freezing mode unnecessarily leads to hypercooling already frozen products and significant waste of electricity.
What happens inside during the Super Freeze mode?
In this mode, the freezer fan operates at maximum speed, and The compressor does not switch off even when the standard temperature reaches -18°C. This creates a powerful flow of cold air, which quickly takes heat away from warm products.
Therefore, the fast freezing mode is not just an “accelerator”, but a necessity for bulk purchases. If your refrigerator model does not automatically turn off this function, be sure to turn it off manually after a day.
- 🧊 Preparation: Turn on the mode a few hours before arriving from the store.
- 🧊 Loading: Lay out the products in one layer for quick access of cold air.
- 🧊 Control: Monitor the operating time of the function so as not to freeze watermelons or melons in the main chamber (if they accidentally ended up there).
Seasonal adjustment and external factors
Ambient temperature directly affects the efficiency of refrigeration equipment. In summer, when the temperature in the kitchen rises above +25°C, heat exchange from the condenser is difficult. In such conditions, it may be necessary to increase the cooling power by 1 notch (for mechanical) or by 1 degree (for electronics). However, if the room temperature exceeds +32°C, even the maximum setting may not cope with the task, and the refrigerator will work almost non-stop.
In winter, the situation is the opposite: in unheated rooms or when the kitchen is very cool, the efficiency may drop, especially for single-compressor models. Some older models are not designed to operate at temperatures below +10°C, as the oil in the compressor thickens and the sensors may not turn on the motor. Modern models DEXP often have an extended climate class, but checking this parameter in the device passport is mandatory.
⚠️ Attention: Do not install the refrigerator in close proximity to heating appliances, stoves or in direct sunlight. Local overheating of one side of the case can cause incorrect sensor readings and incorrect temperature settings.
It is also worth considering the frequency of door openings. In a large family, where the refrigerator is visited dozens of times a day, a lot of warm, humid air enters inside. In this case, it makes sense to keep the temperature slightly below average. If you rarely open the refrigerator, the standard settings will be more than enough.
Diagnostics of problems after setup
After changing the settings, you need to check the operation of the device. If you have set the correct values, but the expected effect does not occur, perhaps the problem is not in the settings, but in a technical malfunction. Signs of problems may include: constant operation of the compressor without entering the rest cycle, the formation of a “coat” of ice on the back wall of the refrigerator compartment (with the system No Frost this is unacceptable), or the appearance of puddles of water under the device.
A frequent mistake is violation of loading rules. If food blocks the vents tightly, cool air does not circulate and the temperature sensor does not register cooling, causing the compressor to run constantly. Make sure there is at least a 2-3 centimeter gap between the food and the back wall. Also check the tightness of the sealing rubber bands on the doors - up to 30% of the cold escapes through the cracks.
In electronic models, problems can be signaled by flashing indicators or sound signals signals. For example, a flashing temperature symbol often indicates that the actual chamber temperature is higher than the set temperature. This could be either a result of a recent load of warm food or a sign of a breakdown. Give the refrigerator a few hours to stabilize before sounding the alarm.
Why does the Dexp refrigerator hum after adjusting the temperature?
Increased noise may be due to the compressor switching to a more powerful operating mode if you have increased the cooling capacity. Also, the source of the sound may be the refrigerant circulating through the tubes, or the operation of the fan in the No Frost system. If the sound does not change to a metallic knock or whistle, this is normal.
How to reset the DEXP refrigerator to factory settings?
In most models, to reset, you need to hold down the settings button or a combination of buttons (for example, Lock + Mode) for 5-10 seconds until the sound signal. In mechanical models, just turn the knob to position 0 (off), wait 5 minutes and return to the desired value. The exact combination depends on the specific series.
Is it possible to change the temperature while the refrigerator is running?
Yes, electronic systems allow you to change settings on the fly. However, a sudden change in the target temperature (for example, from +4°C immediately to 0°C) will cause the compressor to work in forced mode. The electronics themselves will smoothly adjust the operation, but sudden changes in settings are not recommended unless absolutely necessary.
What to do if the display shows an error after setting?
If an error code appears on the screen (for example, E1, F2), this indicates a malfunction of the temperature sensor or defrost system. Try unplugging the refrigerator for 15 minutes to reboot the controller. If the error persists, contact the service center, as further operation may lead to damage to the food.
Does the fullness of the refrigerator affect the temperature setting?
A full refrigerator holds the temperature better (food acts as cold accumulators), but requires more energy for initial cooling. An empty refrigerator cools faster, but when the door is opened, the temperature in it fluctuates more. The adjustment should be made at an average load.
