Modern household appliances of the brand DEXP are becoming increasingly popular due to the successful combination of affordable price and functionality. However, after purchase, many users are faced with the question of what temperature the unit should be set to for optimal food storage. Correct thermostat calibration directly affects the shelf life of food and the energy consumption of the device.
An incorrectly selected operating mode can lead to rapid spoilage of perishable foods or, conversely, to their freezing. In this article, we will analyze in detail the technical features of climate control in models DEXP and determine the ideal parameters for various operating conditions.
It is important to understand that electronic control and mechanical regulation require a different approach. If your device is equipped with digital display, the settings will be more precise, while the rotary controls work on the principle of gradations of compressor power.
Optimal temperature conditions for the main chamber
The main compartment is designed for storing products that do not require deep freezing, but need constant cold. For most models DEXP, regardless of the type of control, gold standard the range is considered to be from +2°C to +5°C. It is at these indicators that bacteria multiply slowest, and the structure of products is not destroyed.
If you set the value below +2°C, you risk freezing vegetables, fruits and dairy products, which will lead to a loss of their taste after defrosting. On the other hand, increasing the temperature above +6°C creates a favorable environment for pathogenic microflora, which is especially dangerous in the summer.
⚠️ Attention: On hot summer days, when the temperature in the kitchen exceeds +25°C, a short-term reduction in the setting to +1°C or +2°C, but only when the refrigerator is fully loaded.
Let's consider the main areas of the main compartment, where the temperature can vary:
- 🥛 Top shelves: Here the temperature is most stable and corresponds to the set values, ideal for ready-made food.
- 🥩 Bottom shelves: Usually here a little colder, which is great for storing raw meat and fish in packaging.
- 🥬 Drawers for vegetables: A special area with high humidity, where the temperature can be 1-2 degrees higher to prevent freezing of cell juice.
Owners of devices with No Frost system should take into account that air circulation can slightly dry out food, so sealed packaging is required.
Setting the freezer compartment
Freezer compartment in refrigerators DEXP usually require lower temperatures to ensure long-term storage of supplies. The standard recommendation for long-term storage is -18°C. With this indicator, products can be stored for up to 12 months without loss of beneficial properties.
Some users mistakenly believe that the colder the better, and set it to -24°C or lower. This leads to excessive load on compressor unit and increased energy consumption without any real benefit to the quality of freezing. Modern refrigerants operate effectively in normal mode.
Particular attention should be paid to the fast freezing mode, which is often designated as Super Freeze. It allows you to quickly cool fresh food to the desired temperature, preventing the formation of large ice crystals inside the cells.
- 🧊 Super Freeze mode: Reduces the temperature to -24°C...-26°C for a certain time.
- ⏱️ Duration: Automatically turns off after 24-48 hours or manually.
- ❄️ Application: Ideal for freezing fresh berries, meat and semi-finished products in large portions.
Differences between mechanical and electronic controls
Model series DEXP includes devices with both mechanical regulators and electronic panels. Understanding the difference between the two is critical to getting the setup right. The mechanical control is a rotary switch with divisions from 1 to 7 (or Min/Max).
It is important to remember the rule here: the higher the number, the lower temperature inside the camera. That is, position “1” is the minimum cooling (warm), and “7” is the maximum power (cold). For everyday use, it is recommended to set the regulator to value 3 or 4.
Why can’t you set the mechanics to maximum?
Constant operation at maximum power (division 7) leads to the fact that the compressor does not turn off. This causes the motor to overheat, the evaporator to freeze and a sharp increase in electricity bills. Use the maximum only for quick freezing or in very hot weather.
Electronic control, represented by a display on the door or inside the chamber, allows you to set precise degrees. There is no need to guess what the number "5" means. You see a specific value, for example +4°C. The accuracy electronic thermostat is usually higher, which ensures a more stable climate.
In models with inverter compressor the electronics themselves smoothly regulate the power, maintaining the set parameter with minimal fluctuations. This extends the service life of the equipment and reduces the noise level.
Seasonal adjustment and external factors
The temperature in the room where the refrigerator is installed has a direct impact on its operation. In winter, when the apartment is cooler, the load on the unit is reduced. In the summer, especially if the kitchen is on the sunny side, heat inflows they make the compressor work harder.
If the refrigerator is located next to a stove, radiator, or in direct sunlight, the standard settings may not be enough. In such cases, the device will try to compensate for external heat, working for wear. It is recommended to reconsider the location of the equipment or temporarily increase the cooling mode.
| Operating conditions | Recommended setting (Main chamber) | Recommended setting (Freezer) |
|---|---|---|
| Standard (summer/winter) | +4°C ... +5°C | -18°C |
| Indoor heat (>26°C) | +2°C ... +3°C | -20°C (or Super Freeze) |
| Indoor coolness (<18°C) | +5°C ... +6°C | -16°C ... -18°C |
| Full load of products | +3°C ... +4°C | -18°C ... -20°C |
It is also worth considering the number of products. An empty refrigerator cools down faster, but holds the cold worse when the door is opened. A loaded unit operates more stably, since the products themselves act as a heat accumulator.
Use of special functions and modes
Many modern models DEXP are equipped with additional functions that help optimize operation. For example, the Vacation mode is designed for long periods when you do not use the main camera.
In this mode, the main camera goes into an energy-saving mode with a temperature of about +12°C...+15°C, which prevents mold and odors, but saves energy. At the same time, the freezer continues to operate as normal, preserving supplies.
Another useful function is Intelligent control. Some models are able to independently adapt to the frequency of door opening. If you often look inside, the system will temporarily increase cooling to compensate for the loss of cold.
- 🏖️ Vacation mode: Saves energy when you are not at home.
- ⚡ Eco Mode: Optimizes operation for minimum consumption.
- 🔇 Quiet mode: Reduces fan and compressor speed (if supported).
These functions are usually activated through the control panel. It is better to find detailed instructions for your specific model in the user manual, since the interfaces may differ.
Diagnostics of temperature problems
Sometimes it happens that even with the correct settings, the refrigerator DEXP does not hold the temperature. This may be due to a malfunction thermal sensor, a freon leak, or a worn door seal. The first sign of problems is often the frequent turning on of the compressor or the formation of ice.
If you notice that the food in the main chamber has begun to deteriorate faster than usual, and the ice is melting in the freezer, you need to check the tightness of the door. A dirty or damaged seal seal lets warm air in, upsetting the balance.
⚠️ Attention: If, after defrosting and correct adjustment, the temperature does not stabilize within 24 hours, a professional repair may be required by replacing the refrigerant or thermostat.
It is also worth checking whether the ventilation holes inside the chamber are not blocked by products. For correct operation of the system No Frost or Total No Frost free air circulation is required. Clogged air ducts lead to local overheating.

Frequently asked questions (FAQ)
Why DEXP refrigerator Is it very cold even at minimum settings?
This may be due to a malfunction of the thermostat, which has stopped reading the temperature correctly, or sticking contacts. Also, in mechanical models, division “1” does not always mean complete shutdown of cooling, but only minimum power. If the problem persists, contact the service center.
How often do you need to defrost a DEXP refrigerator with the No Frost system?
The system No Frost implies automatic moisture removal, so regular defrosting to remove ice is not required. However, it is recommended to turn off the device once every 6-12 months for general cleaning, washing and disinfecting internal surfaces.
Is it possible to change the temperature in the refrigerator while it is working?
Yes, you can change the settings at any time. However, remember that the compressor will take time (from 2 to 12 hours depending on the volume and load) to reach a new temperature regime. You should not turn the regulator every 10 minutes in search of the ideal.
What does a flashing temperature indicator on the display mean?
A flashing indicator usually signals an alarm. This may mean that the temperature inside the compartment has risen above a safe level (for example, after opening the door for a long time or loading warm food). If the flashing does not stop after cooling, the sensor may be faulty.
