Temperature adjustment in a DEXP refrigerator: detailed instructions for all models

Refrigerators DEXP are popular due to the combination of affordable price and functionality, but setting the temperature often raises questions among owners. Incorrectly set parameters lead to overfreezing of food, increased energy consumption, or even compressor breakdowns. In this article, we will look at how to accurately adjust the temperature in the refrigerator and freezer compartments for models DEXP with mechanical and touch controls, and also talk about hidden nuances that the manufacturer does not always indicate in the instructions.

It is important to understand that there are no universal settings: the optimal values ​​depend on the load of the chambers, the temperature in the room and even the type of stored products. We have collected current data on models DEXP 2026-2026, including two-chamber and No Frost systems, and also added tips for diagnosing faults if the refrigerator does not maintain the set mode.

Where is the temperature controller located in DEXP refrigerators

The location of the controls depends on the type of panel:

• 🔄 Mechanical regulator (rotary disk or slider) - most often located inside the refrigerator compartment on the right wall, less often - on the top panel outside. In models DEXP KMR-105 and DEXP RF/NF-120 the regulator is hidden under a decorative cover.
• 📱 Electronic panel —for models with a display (for example, DEXP RF/NF-145W) the setting is located on the outside of the door. In budget options without a screen, there may be a touch panel with buttons +/–.
• ❄️ Separate controls —in two-chamber refrigerators (for example, DEXP KMR-140) separate handles are often installed for the refrigerator and freezer compartments.

If you cannot find the regulator, check:

• 🔍 The backlight inside the camera - sometimes the handle merges with the plastic and becomes noticeable only when the light is on.
• 📄 Instructions for the model - in the “Control” section there is always a diagram with the location of the elements. For DEXP the latest manuals can be downloaded from the manufacturer's website using the model number (indicated on the sticker inside the chamber).

In models with a system No Frost (for example, DEXP RF/NF-160) the temperature regulator can be combined with the mode button Super Freeze. If there is only one knob on the panel, it usually controls both chambers at the same time - this is typical for compact refrigerators with a volume of up to 120 liters.

Optimal temperature conditions for DEXP

The manufacturer DEXP recommends the following ranges:

These values are suitable for most models, but there are exceptions:

• 🥩 For storage fresh meat (up to 2 days) in the refrigerator is better set to +2°C.
• 🍦 If the freezer is less than 50% full, you can raise the temperature to –16°C to save energy.
• 🌡️ In the hot season (at room temperatures above +30°C) refrigerator DEXP can increase the cooling power itself - this is normal and does not require manual adjustment.

In DEXP refrigerators with the Multi Air Flow system (for example, models RF/NF-180), the temperature may differ by 1-2°C between the upper and lower shelves due to the uniform distribution of air. This is not a malfunction, but a design feature.

How to change the temperature: step-by-step instructions

The algorithm depends on the type of control. Below are universal instructions for all models DEXPreleased after 2020.

For a mechanical regulator

1. Find regulator knob (usually labeled Temp or Cold Control).

2. Turn it clockwise for lowering temperature (numbers or marks “1–7” indicate cooling power, not degrees!). In most models DEXP:

   • 🔹 1–2 - minimal cooling (+6°C...+8°C)
   • 🔹 3–4 - optimal mode (+4°C)
   • 🔹 5–7 - intensive cooling (below +2°C)

If in refrigerator has two knobs (for example DEXP KMR-160), the top one is usually responsible for the freezer compartment, the bottom one for the refrigerator compartment.

Wait at least 6 hours before adjusting again - the compressor needs time to reach a new mode.

For electronic control

In models with a display (for example, DEXP RF/NF-145W):

1. Press the button Temp or Fridge (for the refrigerator) / Freezer (for the freezer).

2. Use buttons +/– or touch arrows to set the desired value. The display will show degrees (for example, +4°C).

3. Confirm the selection with the button OK or wait for automatic saving (3-5 seconds).

4. To reset to factory settings hold Temp 5–7 seconds (in some models - a combination Temp + Super Cool).

What to do if the buttons do not respond?

If the control panel does not respond, unplug the refrigerator for 10 minutes, then turn it on again. If the problem persists, check the voltage in the outlet (should be 220–240V) or contact service - there may be a malfunction of the control board.

Features for models with No Frost

In refrigerators DEXP with the system No Frost (for example, RF/NF-160 or RF/NF-180):

• 🌀 The temperature regulator can be combined with a button Super Freeze —hold it for 3 seconds to switch between modes.
• ⚡ When activated Super Freeze the freezer is cooled to –24°C for 24 hours, then automatically returns to the previous settings.
• ❄️ Some models have a separate button Holiday —when pressed, the refrigerator compartment maintains +12°C (economy mode for long absences).

Frequent errors when setting the temperature

Even experienced users sometimes make mistakes that lead to food spoilage or increased energy consumption. Here are the most common ones:

⚠️ Attention: If, after changing the settings, the refrigerator DEXP works without stopping for more than 12 hours, this is a sign of a malfunction. Immediately return the regulator to the middle position and check the door seals.

• ❄️ Too low a temperature in the refrigerator compartment (below). +2°C) - leads to icing of products and increased load on the compressor. This is especially true for models with drip system (for example, DEXP KMR-105), where ice can block the drain for condensation.
• 🔥 The temperature in the freezer is too high (above -16°C) - shortens shelf life meat and fish. In models DEXP s No Frost this also leads to the formation of frost on the back wall.
• 🔄 Frequently changing settings —the compressor takes 6-12 hours to stabilize the temperature. Constant adjustments reduce the life of the motor.
• 🚪 Ignoring the open door — if the refrigerator DEXP squeaks when the door is open, do not turn off the sound with the button Alarm Offuntil you find the reason (for example, skewed shelves or seal).

Another typical problem is uneven cooling. If the upper shelves are warmer than the lower ones, check:

• 📦 Product placement - do not block the ventilation openings (in models with No Frost they are on the back wall).
• 🌀 Operation fan - in refrigerators DEXP RF/NF it should turn on periodically (you can hear a slight noise). If the fan is silent, there may be a malfunction.

How to reset the temperature settings to factory settings

If you have experimented with modes and want to return the original parameters, use one of the methods:

Control type	Reset method	Example models
Mechanical	Turn the knob to position 0 or OFF, then set to 3 (average value)	DEXP KMR-105, KMR-120
Electronic (without display)	Hold the button Temp 5–7 seconds until the sound signal	DEXP RF/NF-120W
Electronic (with display)	Hold Fridge + Freezer for 3 seconds	DEXP RF/NF-145W, RF/NF-160

After reset:

• 🕒 Wait 2-3 hours for the temperature to stabilize.
• 📊 Check the readings with a thermometer - the factory settings may not be optimal for your climate.

⚠️ Attention: In refrigerators DEXP with a function Smart Control (for example, RF/NF-180), resetting the settings can also reset the defrost and filter data. After the procedure, check the indicators on the panel.

Diagnostics of temperature problems

If the refrigerator DEXP does not maintain the set temperature, first eliminate external factors:

If the problem remains, pay attention to the symptoms:

For models DEXP with the system No Frost there is an error E1 or E2 on the display - it indicates problems with the sensors. In this case:

1. Disconnect the refrigerator from the power supply for 1 minute.
2. Turn it on again - if the error remains, the sensor needs to be replaced.

Tips for saving energy

Refrigerators DEXP belong to the energy consumption class A+ or A++, but even they can waste excess energy if used incorrectly. Here's how to reduce consumption:

• 🌡️ Set the temperature in the refrigerator compartment to +5°C (instead of +4°C) - this will reduce consumption by 5-10% without risk to the food.
• 🧊 Regularly defrost models without No Frost (every 3–6 months). A thick layer of ice increases energy consumption by 20–30%.
• 🔌 Do not place the refrigerator next to a stove or radiator - additional heat makes the compressor work longer.
• 📦 Fill the chambers by 60-70% - an empty refrigerator spends more energy cooling the air.

In models with the function Holiday (for example, DEXP RF/NF-160), activate it if you are leaving for a long period. In this mode, the refrigerator compartment maintains +12°C, and the freezer operates in normal mode, which reduces consumption by 30–40%.

FAQ: Frequently asked questions about setting the temperature in DEXP

🔍 Why does the freezer work in the DEXP refrigerator, but the refrigerator compartment does not work? no?

This is a typical sign Freon leaks or Clogged capillary tube. In models with one compressor (for example DEXP KMR-120), the freezer is first cooled, and then the cold enters the refrigerator compartment. If the circuit is broken, the second chamber stops cooling. The solution is to call a technician to diagnose and refill freon.

Other possible reasons:

• Malfunction shift valve (in two-compressor models). DEXP?
• Freezing fan in systems No Frost.

❄️ How to disable Super Freeze mode in DEXP refrigerator?

In most models (for example, RF/NF-145W), the mode Super Freeze turns off automatically after 24 hours. To deactivate it manually:

1. Press the button Super Freeze once (the indicator on the panel will go off).
2. If the button does not respond, hold it for 3-5 seconds.

In mechanical models (for example, KMR-105) this mode is absent - instead, the maximum position of the regulator is used (7).

📉 Why does the temperature in the DEXP refrigerator change itself?

Temperature fluctuations of 1-2°C are normal, especially in models with drip system. But if the spread exceeds 5°C, check:

• Temperature sensor - in refrigerators DEXP No Frost there are several of them, and any of them can fail.
• Door seal - if it is damaged, warm air gets inside, and the compressor is unstable.
• Compressor relay - if there is a malfunction, the motor may turn on/off chaotically.

Also the cause may be overload of products - if the camera is packed to capacity, air circulation is disrupted.

🔧 Is it possible to replace the thermostat in a DEXP refrigerator yourself?

Theoretically, yes, but this requires experience in working with refrigeration equipment DEXP usually located:

• In mechanical refrigerators - inside the chamber, behind the plastic cover next to the regulator.
• In electronic refrigerators - on the control board (on the back wall).

To replace:

1. Disconnect the refrigerator from network.
2. Remove the cover, disconnect the wires from the thermostat (take a photo of the connection diagram!).
3. Install a new thermostat (suitable models: Danfoss 077B6 or Ranco K59 for most DEXP).

⚠️ Attention: Incorrect connection of the thermostat can damage the compressor. If you are not confident in your skills, entrust the repair to a professional.

🌡️ What temperature should be in the freshness zone of the DEXP refrigerator?

Freshness zone (if it is in your model, for example DEXP RF/NF-180) should maintain the temperature 0°C ±1°C. This is optimal for:

• Fresh fish and seafood (stored up to 3 days).
• Greens, berries and fruits (retain vitamins longer than in the main one) camera).
• Cheeses and sausages (do not freeze, but do not spoil).

If your model does not have a separate regulator for the freshness zone, its temperature depends on the general setting of the refrigerator compartment. To achieve 0°C, set the main regulator to 2–3 (in mechanical models).
