Refrigeration The brand's equipment Dexp is distinguished by its affordable price and functionality, however, setting the temperature regime often raises questions among new owners. Correctly adjusting the climate inside the chambers is not just a matter of comfort, but a necessity for maintaining food freshness and saving energy. Many users mistakenly believe that it is enough to simply turn the knob, but in different models this process has its own nuances, depending on the type of control.
In this article we will analyze in detail the mechanics of the operation of thermostats and electronic modules used in the equipment of this brand. You will learn which values are optimal for the freezer and refrigerator compartments, as well as how to avoid common mistakes when starting up the device for the first time. Understanding the operating principles of your model will help extend the life of the compressor.
It is worth noting that temperature stability directly affects the taste of the products. Incorrect settings can lead to overfreezing of vegetables or, conversely, to spoilage of meat products due to insufficient cold. Therefore, it is important to carefully study the instructions and features of the specific modification of your unit.
Types of temperature control in Dexp refrigerators
All models of refrigerators produced under the brand Dexpcan be divided into two main groups according to the type of control: mechanical and electronic. Mechanical control is achieved using a rotary control, usually located inside the refrigerator compartment. Electronic control implies the presence of a display on the outer or inner wall of the case, where parameters are set by buttons or a sensor.
In mechanical models you will not see exact degree numbers. Instead, a scale from 1 to 7 or marking Min/Maxis used. It is important to understand here that the number does not indicate the temperature, but the work intensity compressor. The higher the value, the colder it will be inside the chamber. This is a fundamental point that beginners often miss.
Electronic systems, such as Smart Cooling or standard digital panels, allow you to set precise values in degrees Celsius. Such systems are often equipped with sensors No Frostthat automatically distribute cold air. This eliminates the need for the user to defrost the unit manually and provides a more uniform temperature background.
- 🌡️ Mechanical regulators: simple design, reliability, lack of precise calibration of degrees.
- 💻 Electronic panels: fine tuning, presence of a display, ability to select special modes.
- ❄️ No Frost systems: automatic defrosting, air circulation, which requires consideration when loading shelves.
⚠️ Attention: In mechanical models, setting the regulator to the maximum value (7 or Max) does not mean instant freezing. The compressor will operate continuously, which can lead to its overheating and the formation of an ice crust on the rear wall.
The choice between control types often depends on the price segment and year of manufacture of the model. Budget lines are often equipped with mechanics, while more expensive options with inverter compressor have electronic control. Regardless of the type, the principle of maintaining cold remains the same, only the setting tools change.
Optimal temperature conditions for different products
To ensure long-term storage of products, it is necessary to maintain certain temperature ranges. In the refrigerator compartment, the optimal value is between +2°C and +5°C. It is under these conditions that bacteria multiply slowest, and products do not lose their properties. Freezing of vegetables or the formation of condensation indicates a violation of the regime.
In the freezer, the standard temperature is -18°C or lower. With this mode, products can be stored for up to 12 months without loss of quality. If you plan to store supplies longer, it makes sense to lower the temperature to -20°C or -24°C, but this will increase energy consumption. Some modern models are equipped with a “freshness zone” or zero chamber. This compartment maintains a temperature of about 0°C...+1°C and special humidity. This is an ideal place for storing fresh meat, fish, cheeses and herbs, which quickly spoil or wither in a conventional chamber.
Some modern models Dexp equipped with a “freshness zone” or zero chamber. This compartment maintains a temperature of about 0°C...+1°C and special humidity. This is an ideal place to store fresh meats, fish, cheeses and herbs, which would quickly spoil or wither in a regular storage room.
| Product type | Recommended temperature | Shelf life (approximate) | Placement area |
|---|---|---|---|
| Fresh meat/Fish | 0°C... +2°C | 1-3 days | Zero chamber / Bottom |
| Dairy products | +2°C... +4°C | 3-7 days | Middle shelves |
| Vegetables and fruits | +4°C... +6°C | 5-10 days | Drawers below |
| Frozen semi-finished products | -18°C... -24°C | up to 12 months. | Freezer compartment |
It is important to consider that the temperature on different shelves may vary. The top shelves are usually warmer than the bottom shelves due to the physics of cold air movement. The door is the warmest place, so it is better to put sauces, drinks and foods with a long shelf life there, rather than milk or eggs.
Setting up a mechanical temperature controller
If your refrigerator Dexp is equipped with a rotary knob inside the chamber, the setup process is as follows. Typically, the regulator has a scale from 1 to 5, 1 to 7, or simply designations Min and Max. For initial setup, it is recommended to set the knob to the middle position.
After turning on the device to the network and loading the products, you must wait 6-8 hours. During this time, the compressor will return to operating mode and the temperature will stabilize. If you notice that food is freezing at the back wall, you should turn the knob towards a lower value (closer to Min or 1).
In the hot season or when the chamber is fully loaded, you may need to increase the cold. To do this, turn the knob towards large numbers. However, you should not set the regulator to maximum unless absolutely necessary, as this leads to the motor working without interruption.
☑️ Setting the mechanical thermostat
A common mistake made by users is an attempt to suddenly change the temperature. The mechanical thermostat responds slowly. If you turn the knob, give the system at least a couple of hours to react before making any more adjustments. Sudden changes in settings can disrupt the compressor's operating cycle.
Adjusting electronic controls and display
In models with electronic control, adjustments are made through a panel on the door or inside the chamber. To enter editing mode, you often need to press and hold the Lock or Temp button for 3 seconds. After unlocking, the numbers will begin to flash on the display, indicating readiness for input.
Using the + and -buttons, set the desired value. For the refrigerator compartment the standard is +3°C or +4°C. For the freezer - -18°C. After selecting the value, you need to confirm the action with the button OK or simply wait a few seconds until the system saves the settings automatically.
Some models Dexp have a function Super Freeze (Super Freeze) or Super Cool. These modes temporarily put the compressor in maximum power mode. They should only be used when loading large quantities of fresh food, so that they cool faster without heating up existing supplies.
⚠️ Attention: Do not leave the Super Freeze mode on for more than 24 hours. This places extreme stress on the compressor and can lead to premature failure.
If the display stops responding to touches, the child lock may be activated. In this case, the lock icon lights up on the screen. Unlock (long press) the corresponding button, as indicated in the instructions for your specific model.
What to do if the display is blinking?
Flashing temperature indicators often indicate that the chamber is too warm (for example, after defrosting or loading warm food). This is not a malfunction. Give the refrigerator 4-6 hours to cool, and the blinking will stop on its own.
Special modes and functions of Dexp
Modern refrigerators Dexp can be equipped with additional functions that affect the temperature regime. The "Vacation" mode (Holiday) puts the refrigerator compartment into an economical operating mode (about +15°C), preventing the appearance of mold and odor while the freezer continues to operate normally. This is useful if you are leaving for a long time.
Function Smart Control (in models with Wi-Fi) allows you to control the temperature from your smartphone. Using the app, you can remotely turn on the super freeze before guests arrive or check if the door is open. However, for this function to work, a stable network connection is required.
There is also an “Eco” mode, which optimizes the operation of the compressor for minimal energy consumption. In this mode, the temperature can fluctuate slightly more widely, but the food remains fresh. This is a good choice for everyday use if there are no perishable specific products in the house.
- 🏖️ “Vacation” mode: energy saving, freezer operation only.
- 📱 Smart control: setting via the application on the phone.
- ⚡ Eco mode: balance between food safety and electricity consumption.
The use of special modes requires careful attention. For example, turning on the "Vacation" mode when the refrigerator is full will spoil the food in the main chamber. Always check the current operating status of the device before activating additional functions.
Common problems and their solutions
Sometimes users are faced with a situation where the set temperature does not correspond to the real one. Food in the refrigerator compartment may freeze, or, conversely, ice may melt in the freezer. Most often, the reason lies not in a breakdown, but in improper operation or external factors.
One of the common reasons is a loose door fit. If the seal (rubber band) is dirty or damaged, cold air escapes and the compressor wears out, trying to compensate for the losses. Also, the temperature in the chamber increases if you load it with hot products.
In models with No Frost temperature problems may arise due to blockage of the ventilation holes. If you crowd the shelves tightly with pots and bags so that air does not circulate, the sensors will show incorrect data and the cold will not be distributed evenly.
⚠️ Attention: If you hear a constant hum from the compressor and the temperature does not drop to the set temperature, there may be a freon leak or a faulty thermostat. In this case, self-adjustment will not help - you need to call a specialist.
Also check the location of the refrigerator. If it stands close to the wall or next to the radiator/stove, heat exchange is disrupted. For normal operation, the rear radiator grille requires free air flow. The minimum distance to the wall should be 5-10 cm.
Why does ice freeze in the Dexp refrigerator even though it is set to No Frost?
Most often this happens because the drainage hole is clogged with crumbs or ice. The water does not leave from thawing, freezes and blocks the circulation channels. The refrigerator needs to be defrosted when turned off for 24 hours.
Frequently asked questions (FAQ)
What temperature should the Dexp refrigerator be in normal mode?
The optimal temperature for the refrigerator compartment is considered to be the range from +3°C to +5°C. For the freezer, the standard value is -18°C. These parameters ensure the best preservation of food.
Why does the Dexp refrigerator freeze very much at the back wall?
This is typical for a drip defrosting system. Water flows down the back wall and freezes, forming an ice crust that then melts. If food touches the back wall, it may freeze. Try to move the products away from the wall by 1-2 cm.
How to reset the temperature settings to factory settings?
In most Dexp models, a full reset of the settings (Reset) is performed by long pressing the button combination (often “Lock” + “Temp”) or by disconnecting the device from the network for 10-15 minutes. For the exact combination, see the instructions for your model.
Is it possible to change the temperature when the refrigerator is running?
Yes, you can change the settings at any time. However, the system will not enter the new operating mode instantly, but within several hours. Do not turn the regulator too often, give the compressor time to stabilize the cycles.
What does the flashing temperature indicator on the display mean?
A flashing indicator usually signals an alarm. This may mean that the door has been open too long, the temperature in the chamber has risen above normal, or a system malfunction has occurred. If the blinking does not stop after closing the door and cooling, contact service.
