Modern household appliances require careful attention to the initial settings, and brand refrigeration equipment DEXP is no exception. Correctly setting the temperature conditions immediately after purchase or defrosting allows the equipment to enter the operating cycle without overload, which directly affects the service life of the compressor and the safety of products. Many users encounter difficulties when turning them on for the first time, not knowing which values are standard and which require manual adjustment.
In this article we will analyze in detail the algorithms of actions for various series of refrigerators, including models with a system No Frost and the classic drip type of defrosting. You'll learn how to interpret the display, what flashing lights mean, and why it's important to follow the touch sequence. Ignoring basic adjustment rules can lead to food spoilage or the formation of excessive ice.
Before proceeding with adjustment, it is necessary to allow the unit to settle after transportation and warm up for several hours. This is a fundamental requirement that is often overlooked when trying to immediately set the minimum cold values. Let's look at the basic principles of operation of thermoregulation in the equipment of this manufacturer.
Principles of operation of the DEXP cooling system
Refrigerators DEXP are equipped with electronic control systems that replace old-style mechanical thermostats. The main control element is control modulelocated usually in the upper part of the refrigerator compartment or on the outer door panel. It is he who reads the sensor readings and issues commands to turn the compressor on or off.
The accuracy of temperature maintenance depends on the calibration of the internal sensors. Unlike mechanical models, where turning the knob only approximately changes the mode, electronics allow you to set the value with an accuracy of a degree. However, it is worth considering that the actual temperature in different zones of the chamber may differ slightly from the readings on the display due to air circulation.
⚠️ Attention: During initial setup, do not try to set extremely low values (below +2°C), as this will lead to freezing of vegetables and fruits in the main chamber.
The system distributes cold air through special channels, and it takes time for the mode to stabilize. This process usually takes from 4 to 8 hours depending on the volume of the chamber and the ambient temperature. During this period, the compressor can work almost without stopping, which is normal for reaching the mode.
Control panel interface and indication
The control panel can be located either on outside the door and inside the refrigerator compartment. Depending on the model, the interface can be touch or push-button. The main indicator is a digital display that displays the current temperature in degrees Celsius. For the refrigerator compartment, the standard setting range is from +1°C to +8°C, and for the freezer compartment - from -15°C to -24°C.
Next to the digital values there are often symbols indicating active functions. For example, a snowflake means fast freezing mode, and the image of a glass means a party mode or short-term storage of drinks. Understanding these symbols is critical for the correct operation of the device.
Let's consider the main symbols that you can find on the panel:
- ❄️ Snowflake —activation of the super-freezing mode, in which the compressor operates continuously.
- 🔒 Lock —locking the buttons from accidental pressing children.
- 🔊 Speaker —an indicator of a sound signal warning of prolonged opening of the door.
- 🌡️ Thermometer —blinking of this symbol often indicates an emergency increase in temperature inside the chambers.
Some models are equipped with separate indications for the upper and lower chambers. Switching between refrigerator and freezer compartment settings is accomplished by briefly pressing the appropriate zone selection button. After selecting a zone (usually the corresponding number starts flashing), the value can be changed using the arrow buttons or pressing the main key multiple times.
What to do if the display does not light up?
If the display is silent when you turn it on, check the tightness of the plug in the socket and the presence of voltage. In rare cases, it may be necessary to reset the settings by holding the button combination for a long time (more than 10 seconds), but this depends on the specific model.
Step-by-step instructions for setting the temperature
The process of setting the desired parameters requires sequential steps. You must first unlock the control panel if the lock indicator is on. To do this, most often you need to hold the button with the image of a lock for 3-5 seconds until a characteristic sound signal or the indication changes.
Next, you should select the adjustment zone. Press the mode button to switch focus between the refrigerator and freezer compartments. The active zone will flash. Using the Up or Down buttons, change the numerical value to the value you need. After the blinking stops (usually after 5-10 seconds of inactivity), the new settings are saved in the device’s memory.
For ease of understanding the algorithm of actions, we will make a checklist that will help you not miss a single step:
☑️ Setting the temperature
Dairy It is better to place products on shelves where the temperature is closer to +2..+4°C, and it is better to store vegetables and fruits that are sensitive to cold in special boxes, where the temperature may be slightly higher.
| Product type | Recommended zone | Optimal temperature | Shelf life (approximate) |
|---|---|---|---|
| Meat and fish (chilled) | Zero zone / Bottom | 0..+2°C | 1-3 days |
| Dairy products | Middle shelves | +2..+4°C | 3-7 days |
| Vegetables and fruits | Bottom drawers | +5..+8°C | 3-14 days |
| Ready meals | Upper shelves | +2..+5°C | 1-2 days |
Optimal modes for different seasons
External ambient temperature has a direct impact on the operation of refrigeration equipment. In summer, when the room is hot, the compressor requires more time and effort to remove heat from the chambers. In winter, on the contrary, the load decreases. Many users wonder whether it is necessary to change settings depending on the time of year.
For models DEXP with electronic control, manual seasonal adjustment is rarely required, since smart electronics itself adapts the operating cycles. However, if you notice that food is starting to thaw or, conversely, freeze, manually adjusting the temperature regime will be justified. In summer, it makes sense to set the values 1 degree lower than standard, and in winter - 1 degree higher.
There is also the concept of “holiday mode” or “Eco”. When this function is activated, the temperature in the refrigerator compartment rises to +10..+15°C, which prevents the appearance of odors and mold while saving energy while you are away. The freezer continues to operate normally.
⚠️ Attention: Do not install the refrigerator close to a wall or furniture. For effective heat exchange and correct operation of temperature sensors, a gap of at least 5-7 cm is required on all sides, especially at the back.
If you live in a region with a very hot climate, where the temperature in the kitchen in summer exceeds +30°C, you should consider installing additional ventilation or moving the refrigerator to a cooler place. Operating at the limit of capabilities reduces the life of the compressor.
Decoding error codes and malfunctions
The electronic control system not only regulates the cold, but also diagnoses problems. If alphanumeric codes appear on the display instead of numbers, this is a signal of a malfunction of the temperature sensors or defrost system. Ignoring these signals can lead to a complete stop of the refrigerator.
The most common codes for equipment DEXP are associated with a break or short circuit of the sensors. For example, a code indicating an error in the evaporator sensor indicates that the system does not see correct temperature data and goes into emergency operation mode.
List of common indications:
- 🚨 Flashing temperature —a signal that the current temperature in the chamber is higher than the established norm (often after loading warm products).
- 📡 Wi-Fi symbol (if any) - problems with connecting to the smart home, which does not affect the cold, but blocks remote control.
- ❄️+🔥 Combined indicator - possible malfunction of the No Frost system or defrost heating element.
If persistent errors appear that do not disappear after a reboot (disconnection from the network for 10–15 minutes), it is recommended to contact a service center. Self-repair of electronic circuit boards without qualifications can aggravate the situation.
Is it possible to use a refrigerator with an error?
If the error indicator is on, but the cold is produced, food can be temporarily stored. However, if the error is related to the sensor, the temperature may be incorrect, which is dangerous for perishable food.
Frequently asked questions (FAQ)
Why does the DEXP refrigerator take a long time to reach temperature after turning on?
Initial cooling of empty chambers can take up to 6-8 hours. If you downloaded products at once, the time will increase. Make sure the door is tightly closed and the seal is not damaged. Also check whether the unit is located next to a heat source.
What to do if ice freezes on the back wall in the refrigerator compartment?
In models with a drip system, this is a normal process: moisture flows into the groove during defrosting. If a fur coat forms, check the tightness of the door closure and the condition of the seal. There should be no ice in No Frost models - this is a sign of a malfunction of the defrosting system.
How to reset the settings to factory settings?
Usually, to reset, just unplug the refrigerator from the outlet for 15-20 minutes. In some models with an extended menu, you need to hold down a combination of buttons (for example, “Mode” and “Temperature”) for 10 seconds, but it is better to look for the exact combination in the instructions for the specific model.
Is it possible to install a refrigerator in an unheated country house in winter?
Most refrigerators DEXP are to climate class SN-T or N-ST, which implies operation at ambient temperatures from +10°C to +32°C (or +43°C). Operation at temperatures below +10°C can lead to thickening of the oil in the compressor and incorrect operation of the thermostat.
Why is the temperature indicator flashing in the freezer?
Flashing means that the temperature in the freezer is higher than safe (usually above -15°C). Check that the door is closed tightly, that the vents are not clogged with food, and that the compressor is running. If the blinking continues for more than a day with the door closed, call a technician.
