Initial setup of household appliances after purchase or transportation is a critical stage on which not only the service life of the compressor depends, but also the safety of your products. Owners of Korean appliances are often faced with the need for manual intervention in the operation of electronics, since factory settings not always correspond to actual operating conditions in a particular kitchen. Incorrectly set parameters can lead to the formation of ice, drying out of vegetables, or, conversely, to spoilage of meat due to insufficient cooling.
Modern models of the brand Daewoo are equipped with complex control systems, including inverter compressors and a system No Frostwhich require a delicate approach. Before loading the shelves with products, it is necessary to allow the unit to settle so that the oil in the compressor flows into the crankcase, especially if transportation was carried out in a lying position. Only after this you can begin calibrating temperature modes through the control panel.
In this guide, we will analyze in detail the algorithms of actions for various series of refrigerators, explain the meaning of the indicators and help you avoid typical mistakes that inexperienced users make. Proper settings will allow you to achieve an optimal balance between energy consumption and freezing efficiency.
⚠️ Attention: If the refrigerator has just been delivered from the cold (for example, in winter), do not plug it in for at least 3-4 hours. A sudden change in temperature can damage the electronic control board.
Preparation for the first start and calibration
Before pressing the buttons on the display, make sure that the device is installed level. Leaning forward or sideways interferes with the door's self-leveling system and may cause false alarms of the door closing sensors. Use a spirit level to check the level by turning the adjustable feet clockwise or counterclockwise.
Once plugged in, the control panel will usually beep and all segments on the display will light up to check that the LEDs are working properly. After a few seconds, the device will return to normal mode, displaying the current temperature. Factory settings are often set to average values, which may not be suitable for hot climates or, conversely, for cool rooms.
To get started, you must activate the basic functions. On models with mechanical controls, this is done by turning the regulator inside the chamber, and in electronic versions - through the touch panel. Primary cooling cycle may take from 2 to 4 hours, during which it is not recommended to open the doors.
- 🔌 Check the tightness of the seals throughout perimeter.
- ❄️ Make sure that the ventilation holes inside are not covered with packing tape.
- 📏 Leave a gap of at least 5-7 cm between the back wall and the furniture for air circulation.
☑️ Initial startup
Adjusting the temperature in the refrigerator compartment
The optimal temperature in the main compartment should be in the range from +2 to +5 degrees Celsius. It is at these rates that bacteria multiply the slowest, and products remain fresh for the maximum time. On the display Daewoo this value is usually displayed in large numbers in the left or central part of the screen.
To change parameters, press the button Temp or Fridge (Refrigerator). Each press will change the value by 1 degree. The cycle goes from the minimum possible (usually +1°C) to the maximum (+9°C) or energy saving mode. You should not immediately set the minimum temperature, as this will lead to excessive energy consumption and freezing of food at the back wall.
If you have a model with a fresh zone (Fresh Zone), it may require separate settings. Such compartments maintain about 0 degrees without freezing, which is ideal for meat and fish that you plan to cook in the next 24 hours. Monitor the readings with a probe thermometer placed in a glass of water in the middle of the shelf to obtain accurate data.
It is worth considering that after each change in settings, the compressor needs time to stabilize the mode. Do not change the values too often, let the system work at least one full cycle of on and off.
Setting the freezer and freezing modes
The freezer compartment requires lower temperatures, the standard value is -18 degrees Celsius. This is the “gold standard” for long-term storage, which preserves the vitamins and structure of products. On the control panel, this parameter is adjusted by the button Freezer or Freeze.
For quick freezing of fresh food just brought from the store, refrigerators Daewoo have a function Super Freeze (Super Freeze). When this mode is activated, the compressor runs continuously, ignoring normal rest cycles, until the temperature drops to -24 degrees. This avoids the formation of large ice crystals that destroy the cellular structure of meat or berries.
It is important not to keep the super-freeze mode on all the time. Usually the system automatically turns it off after 24-50 hours (depending on the model), but it is better to control this process manually so as not to overload the engine. After the food is frozen, return to standard settings.
| Mode | Temperature | Purpose | Duration |
|---|---|---|---|
| Standard | -18°C | Long storage | Permanently |
| Super freezing | up to -24°C | Fresh food | Up to 50 hours |
| Eco / Vacation | +14...+17°C | Empty refrigerator | As needed |
| Soft freezing | -6°C | Short-term storage | As needed |
Use of special functions and smart modes
Modern units offer many use scenarios. One of the most useful is the Vacation (Vacation) mode. It is designed for situations where you are away for a long time and leave the refrigerator empty. In this mode, the temperature in the refrigerator compartment rises to +14...+17 degrees, which prevents the appearance of mold and unpleasant odors, but saves energy.
The function Ice Maker (Ice maker) also requires correct activation. If your model has a built-in ice maker, make sure it is connected to the water supply and enable the appropriate option in the menu. The system itself will notify you when it has accumulated a sufficient amount of ice and will pause operation.
Some models support child locking of the control panel (Child Lock). Activation is performed by long pressing (usually 3 seconds) a special button with a picture of a lock. This will prevent the settings from being accidentally changed by curious children or pets who might jump on the door.
⚠️ Attention: Do not store perishable foods, milk or prepared meals in Vacation mode. Leave only the freezer compartment on.
What is Eco mode?
Eco mode automatically adjusts the compressor operation depending on the frequency of door openings and room temperature, optimizing energy consumption without losing storage quality.
Diagnostics of errors and indicators on the display
The refrigerator electronics constantly monitors the state of the system. If you notice flashing lights or alphanumeric codes on the screen, this indicates a problem. For example, a flashing message Alarm or Alert most often indicates that the temperature inside the chambers has risen above the permissible norm.
This can happen immediately after loading a large amount of warm food or due to a door that is not tightly closed. In this case, it is necessary to check the tightness of the closure and give the equipment time (about an hour) to restore the mode. If the signal does not stop, the sensor or fan may have failed.
More serious errors, such as E1, E2 or F1indicate problems with specific sensors (evaporator sensor, defrost sensor). To accurately decipher the error code of a specific model Daewoo it is better to refer to the service documentation, since the encoding may differ depending on the year of manufacture.
- 🔊 Sound signal every 2 minutes - temperature violation.
- 💡 Flashing "No Frost" indicator - a problem with the defrost system.
- 🌡️ "High Temp" indicator - temperature above +10 degrees.
Tips on energy efficiency and maintenance
Correct settings are only half the success. In order for the refrigerator Daewoo to serve for a long time and consume less electricity, it is important to follow the operating rules. Do not place hot food inside as this will cause wear and tear on the compressor. Also, do not overcrowd the chambers: cold air should circulate freely between the products.
Regularly check the condition of the sealing rubber bands. If they are dirty or damaged, the cold will escape, and the sensors will require the compressor to constantly work. Wipe the seals with a soft cloth and soapy water once a month.
Once a year it is recommended to defrost (even for the No Frost system) and thoroughly clean the rear ventilation grilles from dust. The accumulation of fluff and dirt on the heat exchanger significantly reduces the cooling efficiency.
Why does the Daewoo refrigerator hum loudly after setting up?
The hum can be caused by vibration of the case on the floor or furniture. Check the adjustment of the legs. Also, a new compressor may be noisier during the break-in period. If the sound is similar to gurgling, this is normal, the refrigerant is circulating.
What to do if the display does not light up after turning on?
Make sure that the socket is working. If there is power, but the screen does not respond, the power supply protection may have tripped or the control unit may be faulty. Try unplugging the device for 15 minutes to reboot the system.
Is it possible to change the temperature while the compressor is running?
Yes, the electronics allow you to change the settings at any time. However, the new values will take effect only after the completion of the current cycle of operation or rest of the compressor.
