How to correctly set the temperature in the DEXP refrigerator: instructions for all models

Refrigerators DEXP are popular due to the combination of affordable prices and modern features. However, even in simple models, setting the temperature can raise questions - especially if the instructions are lost or written in an incomprehensible language. An incorrectly selected mode leads to freezing of food, excessive energy consumption, or, conversely, insufficient cooling.

In this article you will find step-by-step instructions for all types of refrigerators DEXP —from mechanical to electronic with a display. We will look at how to set the temperature in refrigerator compartment i freezer, which values ​​are considered optimal for different products, and also give tips on saving energy. We will pay special attention to the nuances that the manufacturer often keeps silent: for example, how the frequency of opening the door or the location of the refrigerator in the kitchen affects the temperature.

Types of control systems in refrigerators DEXP

Before you begin configuration, it is important to determine what control system is installed in your model. The algorithm of actions depends on this. Refrigerators DEXP are equipped with three types of panels:

• 🔘 Mechanical adjustment - rotary switch (usually with divisions from 1 to 7 or "Min" to "Max"). Found in budget models, for example DEXP FR-100 or FR-140.
• 📟 Electronic with buttons - control is carried out using the “+” and “–” buttons or touch keys. Typical for series DEXP FR-200 or FR-300.
• 🖥️ Electronic with display - modern models (DEXP FR-400, FR-500) display the current temperature and allow fine adjustment in steps of 1°C.

You can find out the type of control by the appearance of the panel (located inside the refrigerator compartment or on the top of the door) or in the technical data sheet of the device. If the documentation is lost, look for the model on the official website DEXP —there are usually photographs and descriptions there.

⚠️ Attention: In some models DEXP with electronic control, the settings are reset after a power outage. If the refrigerator does not turn on after a power failure, check whether the temperature needs to be adjusted again.

Optimal temperature conditions for the refrigerator and freezer

Manufacturers and sanitary standards recommend maintaining the following temperatures in the refrigerator:

It is important to understand that the temperature inside the chamber is distributed unevenly:

• 🥶 The coldest place —the shelves at the back wall (the evaporator is located there). Ideal for perishable products.
• 🌡️ Medium temperature is the central shelves. Suitable for dairy products, sauces, drinks.
• 🥕 The warmest place —door and lower drawers for vegetables/fruits. Here the temperature can reach +6...+8°C.

In DEXP models with the No Frost system, the temperature difference between the shelves is minimal (1–2°C), while in drip refrigerators it can reach 4–5°C. This should be taken into account when placing products.

How to set the temperature in a DEXP refrigerator with mechanical control

Mechanical regulators are the most reliable, but less accurate. In refrigerators DEXP they are usually a rotary dial with numbers from 1 to 7 (sometimes from "Min" to "Max"). Here's how to set it up correctly:

1. Find the regulator - it is located inside the refrigerator compartment, on the top panel or on the side.
2. Turn the dial clockwise to increase cold, against - to decrease.
3. Focus on the middle position (usually 3–4 for the refrigerator compartment).
4. For the freezer (if the regulator is common) set the value 1-2 divisions higher (for example, 5–6).

To check the accuracy of the setting, use a household thermometer:

Place the thermometer in a glass of water on the middle shelf|Close the door for 12 hours|Compare the readings with the recommended values|If necessary, adjust the regulator-->

⚠️ Attention: In mechanical models DEXP the temperature change occurs with a delay of up to 6-8 hours. Do not try to adjust it more than once a day - this will lead to a delay. increased wear of the compressor.

If your model has two separate regulators (for the refrigerator and freezer), adjust them independently. For the freezer, the optimal position is 5–6, for the main compartment - 3–4.

Temperature setting in electronic DEXP models

Electronic control panels allow you to set the temperature with an accuracy of 1°C. The setting algorithm depends on the type of display:

Models with buttons (without display)

Example: DEXP FR-205W, FR-210B.

1. Find the buttons Fridge (refrigerator) and Freezer (freezer).
2. Press the button of the desired chamber - the current value will flash on the panel.
3. Use the +/– buttons to set the required temperature (for example +4°C for the refrigerator compartment).
4. Wait 3-5 seconds - the setting will be saved automatically.

Models with display

Example: DEXP FR-400N, FR-500S.

1. Press button Menu or Set.
2. Select a section Temperature (can be called Temp Control).
3. Using the buttons ↑/↓ set the values for each camera.
4. Press OK or Save to save.

Some models (for example, DEXP FR-350) have a function Super Cool —intensive cooling for 2-6 hours. It is useful to turn it on. before loading a large number of products.

"Super Freezing" and "Super Cooling" mode: when and how to use

Functions Super Freeze i Super Cool are present in most modern models. DEXP. They are designed for rapid cooling of large volumes of products, but their improper use leads to excessive energy consumption.

• ❄️ Super Freeze (–24…–30°C) —turn on. 4–6 hours before putting food in the freezer (for example, before storing berries for the winter). After freezing, turn off the mode!
• 🥶 Super Cool (+2°C) —useful when loading warm dishes (soups, main courses) Keep it on for no longer than 6 hours.

How to activate:

1. On mechanical models, turn the knob to maximum (7 or Max) for 1–2 hours.
2. On electronic models, press the button Super Freeze or Super Cool (usually illuminated by an indicator).

⚠️ Attention: Continuous operation in the “Super Freeze” mode increases the load on the compressor and can reduce the service life of the refrigerator by 20–30%. Use it only when necessary.

What happens if you forget to turn off Super Freeze?

Prolonged operation in this mode leads to:

- Icing of the evaporator (even in No Frost models),

- Increased noise due to continuous operation of the compressor

- Overconsumption of electricity up to 30–40%.

In older models DEXP (before 2018), the electronic board may fail due to overheating.

Common mistakes when setting the temperature and their consequences

Even experienced users sometimes make mistakes that lead to damage to products or breakdown of equipment. Here are the most common:

• 🌡️ Setting the temperature too low (below +2°C in the refrigerator compartment) - leads to freezing of vegetables, dairy products and loss of their taste.
• ❄️ Ignoring the "Vacation" mode - if the refrigerator is empty for a long time and the mode is not activated, the compressor runs idle, consuming energy.
• 🔄 Frequent temperature changes (for example, when experimenting with settings) - this increases the load on the thermostat and can cause its malfunction.
• 🚪 Prolonged opening of the door - the temperature rises by 5–10°C, and the compressor then it works for wear and tear in order to restore it.

Another typical problem is uneven cooling. If food freezes in one corner of the refrigerator and spoils in the other, check:

• 🔌 Correct connection to the network (voltage should be 220-230V).
• 🧊 Location of products (do not overload the shelves at the back walls).
• 🌬️ Fan operation (in No Frost models it should distribute the cold evenly).

How to save electricity without compromising cooling

The refrigerator is one of the main consumers of electricity in the house (up to 30% of the total consumption). You can optimize its operation without compromising the quality of food storage:

• 💡 Set the temperature to +4...+5°C in the refrigerator and –18°C in the freezer - this is enough for most products.
• 🔌 Connect the refrigerator to the surge protector - this will protect the electronics from power surges that increase energy consumption.
• 🧊 Defrost the freezer when ice forms more than 5 mm thick (even in No Frost models). Ice worsens heat transfer.
• 🌡️ Do not place the refrigerator next to the stove or radiator —every degree of external heat increases energy consumption by 5–7%.

In models DEXP with the function Eco Mode (for example, FR-450E), energy consumption is automatically reduced by 10-15%. If there is no such option, use Holiday Mode during a long absence - it maintains the minimum required temperature.

FAQ: Frequently asked questions about setting the temperature in DEXP

Is it possible to set different temperatures on different shelves?

No, in refrigerators DEXP (as in most household models) the temperature is controlled centrally. However, you can place products on the shelves depending on their cooling requirements: for example, meat - on the coldest shelf (at the back wall), and fruits - in the lower drawers, where it is warmer.

Why does the DEXP refrigerator not cool to the set temperature?

There may be several reasons:

• 🔌 Insufficient voltage in the network (less 200V).
• 🧊 Clogged capillary tube or freon leak.
• 🌡️ Malfunction thermostat or temperature sensor.
• 🚪 Worn door seal (check for any cracks).

If the problem is not in the seal or voltage, a technician needs diagnostics.

How to reset the temperature settings to factory settings?

In mechanical models, it is enough to turn the knob to position 0 or Off, and then return to 3–4. In electronic:

1. Press and hold the button Menu (or Set) for 5-10 seconds.
2. In some models (DEXP FR-500), reset is performed after Settings → Reset → Yes.

After the reset, the temperature will be set to +5°C (refrigerator) and –18°C (freezer).

Do I need to defrost a DEXP refrigerator with a No Frost system?

Yes, but less often - once every 1–2 years. In No Frost systems, ice does not form on the walls, but can accumulate on the evaporator (hidden behind the rear panel). For prevention:

1. Unplug the refrigerator.
2. Take out all the food.
3. Leave the door open for 4-6 hours for ventilation.
4. Wipe the internal surfaces with a weak soda solution.

This will help avoid unpleasant odors and maintain cooling efficiency.

What temperature should be in the freshness zone?

The freshness zone (if your model has one DEXP) should maintain the temperature 0°C … +1°C. This is optimal for:

• Raw meat and fish (stored for up to 3-5 days without freezing).
• Greens, berries and fruits (keep fresh longer than in the main chamber).
• Hard cheeses and sausages (not dries out).

If your refrigerator does not have a separate freshness zone, use the coldest place - the shelf at the back wall.
