Correct setting of the temperature mode is the fundamental basis for the long service life of household appliances and maintaining food freshness. Owners of DEXP equipment are often faced with the need for precise calibration, since the factory settings may not correspond to the current load or seasonal changes in the room. An incorrect microclimate inside the chambers leads to rapid spoilage of food, the formation of ice, or, conversely, excessive energy consumption due to wear and tear of the compressor.
Modern DEXP models are equipped with electronic control, which allows you to adjust parameters with an accuracy of a degree, while simpler versions may require mechanical adjustment of the thermostat. Understanding how your specific model works will help you avoid common mistakes. In this article we will analyze all the nuances of setting, from basic values to fine calibration for different seasons.
Before taking active steps, you need to make sure that the device is connected to the network and operating normally. Temperature balance is not a static indicator, but a dynamic process that depends on many factors. Proper adjustment will extend the life of the compressor and provide ideal storage conditions.
Optimal temperature conditions for different chambers
Each zone of refrigeration equipment is designed for storing certain types of products that require specific conditions. In a DEXP refrigerator, the ideal range is considered to be +2 to +5 degrees Celsius. It is at these indicators that the growth of bacteria slows down, but the products do not freeze, maintaining their structure and taste.
The freezer requires more extreme values. The standard setting for storage is -18°C or lower. If you plan to freeze large volumes of fresh food at the same time, it makes sense to temporarily turn on the mode Super Freeze, which will lower the temperature to -24 degrees, providing rapid freezing without the formation of large ice crystals that destroy the cellular structure.
⚠️ Attention: Setting the temperature below -24 degrees in normal mode has no practical meaning and leads to a significant increase in energy consumption without improving the quality of storage.
In models with a freshness zone (zero chamber), the parameters may differ. It is usually maintained around 0 degrees and high humidity. This is an ideal place for meat, fish and vegetables that you plan to cook in the coming days.
Electronic control: setting via display
Most modern DEXP refrigerators are equipped with a control panel with an LED display located on the outside of the door. The interface may vary depending on the series, but the logic remains the same. To start setting up, you usually need to press and hold the button with the image of a lock for 3-5 seconds to unlock the control panel from accidental changes.
After unlocking, the indicator of the selected camera lights up on the screen. Use the arrow buttons or the “+/-” symbol to change the value. The compressor takes time, usually from 30 minutes to 2 hours, to stabilize climate inside the chamber to new parameters.
- 🔹 Press the button
Lockto unlock the panel. - 🔹 Select a zone adjustments (refrigerator or freezer).
- 🔹 Use the setting buttons to change the numerical value.
- 🔹 Confirm your choice or just wait a few seconds until the indicator stops flashing.
Some models support a function Smart Controlthat allows you to control temperature via an application on a smartphone if the refrigerator is connected to Wi-Fi. This is a convenient way of monitoring, but the basic setting is still duplicated on the device itself.
Mechanical thermostat adjustment
In classic DEXP models without a digital display, adjustment is carried out using a mechanical thermostat. It is a rotary switch located inside the refrigerator compartment, often on the side wall or under the ceiling light. The scale can be marked with numbers from 1 to 7 or words like “Min” and “Max.”
A simple rule applies here: the higher the number, the colder it is. However, you should not blindly trust the numbers, since they do not indicate degrees, but the degree of intensity of the compressor. Position "3" or "4" usually corresponds to factory recommendations for most situations. Moving the regulator to the maximum position makes the motor work almost without stopping.
Why can’t you set the mechanics to maximum?
Constant operation of the compressor at maximum loads leads to its rapid wear, overheating and a significant increase in electricity bills. In addition, food near the back wall may freeze.
For precise adjustments in mechanical models, it is better to use an external thermometer. Place it in a glass of water on the middle shelf and leave it overnight. In the morning, check the readings and, if necessary, adjust the position of the regulator. This is the only way to obtain objective data about the real temperature inside.
Seasonal adjustment and influencing factors
The temperature in the room directly affects the operation of the refrigeration unit. In the summer, when the kitchen is hot, heat transfer occurs more slowly and the compressor requires more time and energy to maintain the set parameters. In winter the situation is reversed. Owners should take these nuances into account when operating DEXP equipment.
During the hot period of the year, it is recommended not to set the regulator to the minimum values (maximum cold) unless there is an urgent need for it. It is better to ensure good ventilation of the rear radiator grille. In winter, if the refrigerator is in an unheated room or near a cold wall, standard settings can lead to insufficient cooling, since the thermostat will “think” that it is already cold inside.
| Season | Recommended setting (Mechanics) | Recommended setting (Electronics) | Features |
|---|---|---|---|
| Summer | 3-4 (average) | +4°C (cold), -18°C (frost) | Keep an eye on ventilation |
| Autumn/Spring | 3 (standard) | +3..+4°C | Optimal mode |
| Winter | 4-5 (closer to maximum) | +2..+3°C | Control of operation in unheated premises |
The number of products also affects the load. A full refrigerator holds the cold better, but requires more energy for initial cooling. An empty unit reacts faster to opening the door, losing cold.
☑️ Checking operating conditions
Quick freezing and super-cooling modes
Functions Super Freeze (super freezing) and Super Cool (super-cooling) are intended for emergency situations. They are often used after purchasing large quantities of groceries or before loading fresh meat and fish. In this mode, the compressor operates continuously, ignoring the thermostat readings.
It is important not to leave the refrigerator in this mode for a long time. On most electronically controlled DEXP models, the function turns off automatically after a certain amount of time (usually 24-48 hours) or when the target temperature is reached. In mechanical models, this function must be turned off manually by returning the switch to its original position.
⚠️ Attention: Long-term operation in super-freezing mode (more than 3 days) can lead to freezing of the evaporator and failure of the condensate drainage system, especially in No Frost models.
Use these modes rationally. If you just need to cool a few bottles of drinks, it is better to place them in the maximum cold zone for a short time than to put the entire unit into stress mode.
Common mistakes and their consequences
One of the most common mistakes is setting the minimum temperature immediately after defrosting or first turning on. The unit should return to mode smoothly. A sharp start at the limit values creates a peak load on compressor starting currentwhich reduces the life of the motor.
Another mistake is covering the ventilation holes inside the chamber with products. Cold air should circulate freely. If you fill the shelves to capacity, the temperature sensor may show incorrect data, and the products deep in the chamber will begin to deteriorate while the sensor receives a signal that it is “normal.”
You should also not change the settings often. Every change takes time to stabilize. If you have just turned the knob, give the technique at least 5-6 hours before assessing the result and turning it further. Constant jumps in operating conditions are harmful to the refrigerant and oil in the system.
Diagnostics of temperature problems
If you have set everything according to the instructions, but the temperature does not hold, the problem may not be in the settings. Check the tightness of the door sealing rubber. If it is worn out or dirty, the cold will evaporate, and the compressor will hum without interruption, trying to compensate for the losses.
It is also worth paying attention to the location of the temperature sensor. In No Frost refrigerators it is often hidden behind a plastic panel. If the sensor has moved or ice has formed on it, the readings will be incorrect. In such cases, professional defrosting or sensor replacement may be required.
Why does the DEXP refrigerator hum after adjusting the temperature?
The hum may increase if you set the temperature too low, forcing the compressor to work at its limit. The sound may also be related to the circulation of refrigerant. If the noise does not go away an hour after entering the mode, check the stability of the refrigerator installation.
Can medicines be stored in a DEXP refrigerator?
Medicines can only be stored in the main compartment of the refrigerator (not in the door or in the freezer), if the instructions for the medicine require a temperature of +2..+8°C. However, make sure that they do not come into contact with the food and are in a closed container.
What to do if ice forms in the DEXP chamber?
Ice formation often indicates a leak or a malfunction of the defrost system. Check if the water drainage channel is clogged. Ice may also appear if the temperature is set too low for the current humidity in the room.
How to reset the temperature settings to factory settings?
In electronic DEXP models, a full reset (Reset) is usually performed by long pressing the button combination (for example, Freeze + Cool simultaneously for 5-10 seconds). It is better to check the exact combination for your model in the instructions, as it may differ.
Does the color of the case affect the temperature inside?
No, the color of the external surface (black, white, silver) does not affect the internal climate if the refrigerator is not placed in direct sunlight. Dark colors can only heat up more from the sun, which indirectly makes the compressor work more actively.
