Modern refrigerators brands DEXP have proven themselves to be reliable and functional devices, but for their effective operation they often require competent initial setup. Many users are faced with a situation where, after purchase or long-term transportation, the equipment does not work correctly, does not freeze properly, or makes strange sounds. Often the problem lies not in a breakdown, but in incorrectly set parameters or violation of installation rules.
Adjustment temperature conditions is the first step that must be taken after connecting the unit to the network. Incorrect settings can lead to food spoilage, ice formation, or, conversely, to defrosting of supplies. Understanding the principles of operation of your specific DEXP will allow you to avoid unnecessary calls to the technician and extend the life of the compressor.
In this guide we will examine in detail all aspects of the setup: from setting the degrees in the chambers to adjusting the legs and checking the tightness. Calibration equipment takes a little time, but provides a stable microclimate inside the chambers. Follow the instructions to ensure that your refrigerator operates in optimal conditions.
Initial preparation and installation rules
Before you begin adjusting the electronics or mechanical controls, you must ensure the correct physical conditions for the operation of the unit. If the refrigerator was delivered in winter, it requires acclimatization. Compressor oil Must warm up to room temperature so as not to damage the system when first started.
Install the equipment on a flat surface. The tilt of the housing affects the operation doors and the condensate drainage system. If the floor is uneven, use adjustable feet. This may require a wrench or screwdriver, depending on the model DEXP. It is important that the back wall does not lie flush against the wall - the gap is necessary for air circulation.
⚠️ Attention: Do not plug in the refrigerator immediately after transportation if it has been lying down. Let it stand upright for at least 4-6 hours to allow the refrigerant and oil to drain into the compressor.
Check the integrity of the door seals. They should fit snugly around the entire perimeter. If the door does not close tightly, no amount of electronic adjustment will help maintain the desired temperature. Make sure that there is a gap between the shelves and the walls of the chamber for free circulation of cold air.
☑️ Check before turning on
Setting temperature conditions in the chambers
Central control element in refrigerators DEXP is the temperature control panel. Depending on the model, this may be a mechanical rotary switch or an electronic panel with a display. Optimal temperature in the main chamber should be from +2 to +5 degrees Celsius.
For mechanical regulators, the scale is usually numbered from 1 to 5 or from Min to Max. The number does not mean the number of degrees, but indicates the intensity of the compressor. The higher the number, the colder it is. For everyday use, it is recommended to set the regulator to the middle position, for example, 3 or 4.
Electronic models allow you to set the exact value. Use the + and - buttons on the control panel. After changing the settings, the compressor will take time (from 2 to 6 hours) to stabilize the climate inside the chambers. Do not load the products completely until the mode is established.
In the freezer, the temperature should not be higher than -18 degrees. This value ensures long-term storage of meat and fish without loss of their properties. If you use the fast freezing mode, do not keep it turned on constantly, so as not to overload the refrigeration unit refrigeration unit.
Adjusting the No Frost and defrosting system
Most modern models DEXP equipped with a system No Frostwhich prevents the formation of ice crust. However, even such systems require proper configuration and periodic maintenance. If you notice snow on the back wall or in the corners, the defrost cycle may be broken.
Check that the air ducts are not blocked by food. Cold air should circulate freely from the evaporator to the shelves. If the damper Air Flow is blocked by a bag or box, the temperature sensors will read incorrect data and the compressor will operate intermittently.
| Parameter | Normal value | Fault symptom |
|---|---|---|
| Temperature in the chamber | +3...+5 °C | Food freezes or spoils |
| Temperature in the freezer | -18...-24 °C | Soft ice, ice |
| Compressor operating time | Cyclic | Works without stopping |
| Noise level | Up to 40 dB | Humming, knocking, whistling |
Sometimes manual operation is required defrosting, even if No Frost is declared. This happens when the drain hole becomes clogged. Clean the water drainage channel with a soft wire or brush so that the defrost system works correctly. The water must go into the pan above the compressor and evaporate.
Why does ice form with No Frost?
The No Frost system does not mean a complete absence of ice. Ice is formed on the hidden evaporator and then melted by the heater. If ice appears inside the chamber, it means that the outflow of water or the seal of the door is broken.
Eliminating noise and vibration during operation
A new refrigerator DEXP may make sounds that at first seem strange. This could be the noise of refrigerant moving through the pipes or the clicking of the thermostat. However, strong vibration often indicates incorrect installation.
Check the horizontal installation using a building level. If the body is skewed, the vibration from the running motor is transmitted to the floor and intensified. Tighten the front legs so that the refrigerator is stable. Also check that the pipes are not touching the wall or furniture at the back.
- 🔊 Check that the refrigerator is not leaning against the wall or cabinets - a gap of at least 5 cm is needed.
- 🔧 Tighten the compressor mounting bolts if the vibration is coming from below (caution required).
- 🧊 Make sure that bottles and cans inside the chamber are not in contact with each other or with the walls.
If the humming gets louder at night when the house is quiet, this may be normal for inverter compressors that operate at low speeds for a long time. But if the sound is sharp, metallic or accompanied by knocking, you should contact the service.
Setting up additional functions and modes
Many models DEXP are equipped with additional options, such as “Vacation”, “Super cooling” or child lock. Mode "Vacation" (Vacation) switches the main chamber to economy mode (about +15°C), leaving the freezer working. This prevents the appearance of mold and odor during prolonged absence.
The control panel locking function (Lock) is useful in families with children. Typically, to activate, you need to hold the button with the image of a lock for 3-5 seconds. The corresponding indicator will light up on the display. This will prevent accidental changes to the temperature settings.
⚠️ Attention: Specifications and button locations may vary depending on the specific series of the DEXP refrigerator. Always refer to the paper instructions included in the kit, as control panel interfaces may be updated by the manufacturer.
Super Freeze mode forcibly turns on the compressor at maximum power. Use it only when loading a large volume of fresh food. Do not forget to turn off this mode manually after 24 hours if it does not turn off automatically to avoid wasting electricity.
Diagnostics and reset
If, after all the adjustments, the refrigerator DEXP behaves strangely (the indicator blinks, does not hold the temperature), try resetting the settings to factory settings. Often a failure occurs in electronics logical controller, which is cured by rebooting.
To reset, unplug the refrigerator for 10-15 minutes. Then turn it on again. If the problem was a software glitch, the device should work correctly. If the indicators continue to flash, pay attention to the error code, which may be displayed on the display or a combination of flashes.
- 🚫 The indicator is flashing - check that the door is closed tightly.
- ❄️ The snowflake is on - the fast freezing mode is activated.
- 🔔 Alarm sound - the door open time has expired or the temperature regime has been violated.
Continuous operation of the compressor without shutting off may indicate a freon leak or a thermostat malfunction. In such cases, self-adjustment will not help; diagnostics by a specialist using pressure gauges and a leak detector is required.
Frequently asked questions (FAQ)
What temperature should be set in the DEXP refrigerator in the summer?
In the summer, when the ambient temperature in the kitchen is high, it is recommended to set the regulator to a value slightly below average (for example, 3 out of 5) to compensate for heat gains. Do not set the maximum cold, this will lead to overload.
Why does the DEXP refrigerator not freeze after defrosting?
After defrosting, the device takes time (up to 6-8 hours) to reach the temperature. If after a day there is no cold, check whether the compressor is working (listen at the back wall) and whether the light inside is on when you open the door.
What does a flashing temperature indicator mean?
A flashing indicator usually indicates that the temperature in the chamber is above the set norm. This can happen immediately after turning on, after loading warm food, or when the door is not tightly closed.
Is it possible to adjust the legs of the refrigerator without an assistant?
Yes, the front legs often have threads that allow you to tighten them with a key or by hand, slightly lifting the corner of the case. However, to fine-tune the level, it is better to call an assistant to control the position of the bubble.
