How to properly turn on the freezer in a Liebherr refrigerator: all the methods and nuances

Refrigerators Liebherr are famous for their reliability and innovative technologies, but even with such equipment, users have questions about basic operation. One of the most common is how to turn on the freezer, especially if it is turned off after defrosting, moving or a power failure. In this article we will analyze all possible scenarios: from standard activation to solving emergency situations.

It is important to understand that the process of activating the freezer depends on refrigerator models, the type of cooling system (NoFrost, SmartFrost or drip) and even on the year of manufacture. For example, in new series with touch control, the algorithm differs from classic models with mechanical regulators. We will cover all the options so that you can quickly navigate.

If your Liebherr is equipped with a function SuperFrost (intensive freezing), its inclusion also has nuances - this is a separate section. And for owners of two-compressor models, here is a diagram of independent control of the freezer and refrigeration compartments.

1. Standard activation of the freezer: step-by-step instructions

In most models Liebherr the freezer turns on automatically when the refrigerator is connected to the network, but sometimes manual activation is required. Here is a universal algorithm for refrigerators with one compressor (series CN, CP, CBP):

  1. Check food. Make sure that the refrigerator is connected to the outlet and the indicator is on on the display (if any). In models without a screen, you should hear a slight noise of the compressor.
  2. Find the freezer temperature regulator. It can be:
    • 🔘 Mechanical - a rotary dial with divisions from 0 (off) to 4-5 (maximum cold).
    • 📱 Electronic - buttons +/ or touch arrows next to the snowflake icon ❄️.
    • 🖥️ On the display - menu Temperature → Freezer (in series SIK, BS).
  • Set the temperature. The optimal value is –18°C (corresponds to the position 3-4 on the mechanical regulator). In electronic models, the temperature is displayed on the screen.
  • Wait for the start. The compressor may not turn on immediately - give the refrigerator 5-10 minutes. The start of operation is indicated by a quiet hum or a lighted indicator Cool/Freeze.
  • In two-compressor models (SBN, SBes), the freezer is controlled separately. turn on:

    1. Find the button Freezer On/Off (usually located on the top panel or inside the freezer compartment).
    2. Hold it for 3-5 seconds until a sound signal or indication changes.
    3. Adjust the temperature in the same way as in step 3.

    Power is connected to a 220V socket

    The freezer door is tightly closed

    The temperature regulator is not in the "0" or "Off" position

    No errors on the display (flashing indicators, fault codes)-->

    2. Features of inclusion in models with NoFrost and SmartFrost

    Technologies NoFrost and SmartFrost from Liebherr assume automatic defrosting, but after a long shutdown or transportation, the freezer may need to be turned on manually. Here are the key ones. differences:

    Technology How to turn on the freezer Time to enter mode Features
    NoFrost Temperature regulator in position 3-4 or button SuperFrost (if available) 1–2 hours The fan may make noise for the first 30 minutes - this is normal
    SmartFrost Button Freezer + setting the temperature to display 1.5–3 hours Requires mandatory initial defrosting after transportation
    Drip system Mechanical regulator in position 2-3 2–4 hours It is necessary to check the drain hole for the presence of ice

    In refrigerators with NoFrost after turning on the freezer, the function may work auto defrost - do not be alarmed if after 10-15 minutes the compressor turns off for a short time.

    For models with SmartFrost (for example, series CBPesf) before turning on for the first time after purchase or long-term inactivity:

    1. Wipe the internal surfaces with a dry cloth.
    2. Make sure that the drainage hole (at the bottom of the back wall) is not clogged.
    3. Turn on the freezer and wait for a signal (sound or light) that the set temperature has been reached.
    4. 3. SuperFrost function: when and how to use it

      Mode SuperFrost (intensive freezing) is available in most models Liebherr medium and premium class. It is needed for:

      • 🍗 Quick freezing of large batches of food (for example, after purchasing meat or berries).
      • ❄️ Restoring the temperature after defrosting or a power outage.
      • 🧊 Making ice in large quantities (relevant for models with ice maker).

    How to turn it on SuperFrost:

    1. Find the button with the ❄️❄️ icon or inscription SuperFrost (usually on the control panel or inside the freezer).
    2. Press it once - the indicator will light up (yellow or red, depending on the model).
    3. The mode works maximum 65 hours, after which it automatically turns off, going to the standard mode.

    In models with a display (SIK 3556, BSes 4356) the path to activation may look like this:

    Menu → Special Functions → SuperFrost → On
    ⚠️ Attention: Do not leave SuperFrost on constantly - this increases energy consumption by 20-30% and the load on the compressor. Use the mode only when necessary.
    What what to do if SuperFrost does not turn off automatically?

    If the mode indicator is on for more than 65 hours, this may indicate a malfunction of the temperature sensor or control board. Try to manually turn off the mode with the button, then reset the refrigerator (unplug it for 10 minutes) If the problem persists, diagnostics are required.

    4. solutions

    If after all the manipulations the freezer does not start, check the following points:

    Cause How to check Solution
    No power The indicators on the panel do not light up, there are no operating sounds Check the socket, plug, circuit breaker in the panel
    Overheat protection has tripped The compressor is hot, the refrigerator turns off after 1-2 minutes Disconnect for 1–2 hours, provide ventilation for the rear wall
    The thermostat or sensor is faulty The freezer does not respond to temperature changes The sensor needs to be replaced (call a technician)
    The fan is jammed (in NoFrost) A hum is heard, but the cold does not accumulate Defrost the refrigerator for 12 hours, check the fan blades

    In models with electronic control (Liebherr IK 3560, SBes 7256), a malfunction is indicated error codes on display:

    • F1 —problem with the freezer sensor.
    • F3 —fan malfunction.
    • F5 —compressor error.

    To reset the error:

    1. Disconnect the refrigerator from the network for 5 minutes.
    2. Plug it back in and hold the button Alarm Reset (or Ok) for 10 seconds.
    3. If the code appears again, contact the service center.
    ⚠️ Attention: If the freezer does not turn on after transportation, wait 4-6 hours before starting it for the first time. This time is needed to stabilize the refrigerant pressure in the system.

    5. Turning on the freezer after defrosting or moving

    After defrosting or moving the refrigerator Liebherr the freezer is turned on taking into account several rules:

    1. Dry camera. Wipe all surfaces dry, remove any remaining water from the drainage hole.
    2. Set the initial temperature. To speed up cooling, set the regulator to –24°C (maximum) for 1-2 hours, then return to –18°C.
    3. Do not load products immediately. Wait until the freezer reaches the temperature (signal on the display or the noise stops compressor).

    For models with BioFresh (freshness zone) after defrosting:

    • 🥬 Turn on the zone BioFresh separately (button with leaf or inscription 0°C).
    • 🌡️ Set the temperature +1°C for storing meat/fish or +4°C for fruit.

    If the refrigerator was transported in a horizontal position:

    1. Let it stand vertically 6–12 hours before turning on (to distribute the oil in the compressor).
    2. During the first day, do not fill the freezer more than 50%.

    6. Controlling the freezer via a mobile application (for smart models)

    Refrigerators Liebherr series SmartDevice (SIK 4856, BSes 7256) support control via the application Liebherr SmartDevice. To turn on the freezer remotely:

    1. Connect the refrigerator to Wi-Fi (instructions in the user manual).
    2. Install the application on your smartphone (available for iOS and Android).
    3. Log in and add the device by serial number (located on the sticker inside the refrigerator).
    4. In the section Temperature Control select Freezer and set the desired value.

    The application also offers functions:

    • 📊 Monitoring temperature real time with notifications of deviations.
    • ❄️ Remote activation of SuperFrost (for example, before returning from the store).
    • 🔔 Setting up signals (open door, rising temperature).

    For models With Home Connect (integration with a smart home), the freezer can be turned on by voice via Alice, Google Assistant or Siri. Example command: "Alice, set the freezer to -18 degrees".

    ⚠️ Attention: Smart control functions may vary depending on the firmware of the refrigerator. Before use, check the available options in the application menu.

    7. Energy saving: optimal freezer settings

    To ensure that the freezer Liebherr works efficiently and does not waste excess energy, follow these recommendations:

    • 🌡️ Temperature: –18°C —the optimal balance between food safety and energy consumption. Reducing to –24°C increases energy consumption by 15–20%.
    • 📦 Loading: Do not fill the freezer more than 70%. Air circulation should be free.
    • 🔄 Defrosting: Even for NoFrost carry out general cleaning 1-2 times a year (turn off, wash, dry).
    • 🚪 Door: Minimize opening time. In models with an alarm (DoorAlarm), the signal is triggered after 60 seconds.

    In refrigerators with inverter compressor (series Premium, Monolith), energy consumption depends on external conditions:

    Room temperature Recommended freezer setting Approximate energy consumption
    16–22°C –18°C 0.8–1.2 kW/day
    23–28°C –20°C 1.3–1.7 kW/day
    Below 16°C –16°C 0.6–0.9 kW/day

    For additional savings in models with SmartGrid activate mode Eco (in the menu Energy Saving). It automatically adjusts the operation of the compressor depending on electricity tariffs (if a meter with differentiated tariffs is connected).

    FAQ: Frequently asked questions about turning on the Liebherr freezer

    The freezer is on, but does not freeze - what to do?

    Check:

    1. Whether the door is closed (perhaps the seal is damaged or the product is interfering).
    2. Is the mode Holiday (vacation) turned on, in which the freezer turns off.
    3. Working is there a fan (in models NoFrost its noise should be audible).

    If everything is in order, but the cold does not accumulate, call a technician to check the refrigerant.

    How to turn on the freezer if the display is broken?

    In most models Liebherr the freezer is also controlled through mechanical buttons:

    1. Find a button with the ❄️ icon on the panel (usually under the display).
    2. Hold it for 5 seconds - the freezer will turn on in standard mode (–18°C).
    3. To change the temperature, use buttons +/ (they can be hidden under a removable panel).

    If the buttons also do not respond, the problem is in the control board.

    Is it possible to turn on the freezer separately from the refrigerator?

    Yes, but only in two-compressor models (Liebherr SBN, SBes). To do this:

    1. Find the button Freezer On/Off (usually on the top panel).
    2. Hold it for 3 seconds - the freezer will turn on, but the refrigerator compartment will remain off.

    In single-compressor refrigerators, it is impossible to turn off the refrigerator compartment - the compressor works on both compartments.

    How long does it take the freezer to reach the temperature after turning on?

    The time depends on:

    • 🌡️ Initial temperature in the chamber (after defrosting - up to 6 hours, after a short-term shutdown - 1-2 hours).
    • 📦 Loading (an empty freezer will cool faster).
    • 🏠 Room temperatures (in hot weather the process slows down).

    The readiness signal is:

    • A sound signal (in models with Acoustic Signal).
    • The indicator goes out Alarm (red light).
    • Display of the set temperature on the display.
    What to do if an unpleasant odor appears after turning on the freezer?

    This is normal after defrosting or turning it on for the first time. To eliminate the smell:

    1. Rinse the camera with a soda solution (1 tablespoon per 1 liter of water).
    2. Wipe the door seal with vinegar (9%).
    3. Place an adsorbent (a bag of activated carbon or a special odor absorber) in the freezer.
    4. Turn on the freezer at maximum cold (–24°C) for 2-3 hours - low temperature kills bacteria.

    If the smell remains for more than a week, check the drainage hole for blockages.
