Use the space in your kitchen efficiently with the BOSCH KGN39VXCT Serie 4 combi fridge freezer, which you can place anywhere. The appliance doesn't need any extra space around it, so you can easily place it right up against a wall or next to furniture or a kitchen unit. The entire refrigerator compartment of the BOSCH KGN39VXCT Serie 4 is illuminated by energy-saving, glare-free LED lights. Thanks to the Total No Frost technology, you'll never have to defrost the fridge again. The large VitaFresh XXL drawer creates the optimal climate for fruit, vegetables and meat, keeping them fresh for longer. The super cooling function ensures that already chilled food does not warm up when new food is added. What's more, the BOSCH KGN39VXCT Serie 4 fridge won't disturb you with its operation, as its noise level does not exceed 35 dB.

Uneven cooling can negatively affect the taste and shelf life of food. Bosch fridges with Multi Airflow technology ensure an even distribution of humidity and temperature throughout the entire interior – from the door compartments to the back corners. Your food stays fresh and tasty for longer.
The spacious VitaFresh XXL drawers in the BOSCH KGN39VXCT Serie 4 fridge offer plenty of space and the ideal storage environment for all your fresh food. Fish and meat stay fresh for longer at a temperature close to <0°C>. Fruit and vegetables retain all their vitamins thanks to the optimal humidity in the drawer.
With Total No Frost technology, it is not necessary to defrost the freezer regularly. The system wicks away moisture and keeps the air dry, which limits the formation of frost on the freezer walls and on food. The same principle also works in the refrigerator compartment, where it helps prevent the formation of water droplets and frost on the back wall. This makes maintenance easier and the appliance retains its high energy efficiency.
The BOSCH KGN39VXCT Serie 4 fridge has been designed so that you can place it absolutely anywhere. The PerfectFit technology allows you to place the fridge as you wish, for example against a side wall or directly against furniture, no clearance is needed. You are not limited by a lack of space. The BOSCH KGN39VXCT Serie 4 fridge is especially suitable for those who do not want a built-in fridge, but wish to make the best use of their kitchen unit space.
If you forget to close or don't fully close the fridge door, a light and an audible alarm will alert you after a short time. In the same way, the BOSCH KGN39VXCT Serie 4 will let you know if any other error occurs.
The LED lighting ensures that the interior of the fridge is evenly illuminated. Compared to standard bulbs, it consumes less energy and has a longer service life.
In the BOSCH combination fridge, the freezer and fridge sections each have their own circuit. This allows the temperature to be set individually.
Activating the SuperCooling or SuperFreezing function will very quickly cool or freeze food that has just been placed in the BOSCH KGN39VXCT Serie 4 appliance. The function prevents food already in the fridge from warming up, ensuring it stays fresh for longer.
The front of the BOSCH KGN39VXCT Serie 4 fridge is treated with a special permanent coating that prevents fingerprints.

Yes, on most models it is possible to change the door opening direction. We recommend consulting the user manual for your specific appliance for instructions or contacting an authorized service center.
Transporting the refrigerator lying down is not recommended as it can damage the compressor. If it is necessary, let the refrigerator stand upright for at least 24 hours after transport before plugging it in.
Yes, this is normal. The condenser, which dissipates heat from the inside of the refrigerator, is integrated into the side walls, causing them to heat up.
No, do not remove this cover. It is often made of a sturdy material resembling cardboard and serves as protection and insulation for the back of the appliance.
Yes, with new refrigerators, especially those with an inverter compressor, it is common for them to run longer initially to reach the set temperature. Modern compressors can operate for longer periods at lower power.
No, do not remove the plastic wrap, tape, or any other protective elements on components that are not explicitly marked for removal after transport. To be sure, check the installation manual.
Check if the drain hole at the back of the refrigerator is clogged. Increased moisture can also be caused by storing unwashed or unwrapped vegetables.
No Frost technology completely prevents ice buildup in the freezer through air circulation, so it never needs to be defrosted. Low Frost technology significantly reduces ice formation, but occasional manual defrosting is still necessary.
Yes, on most combination refrigerators, the freezer temperature can be adjusted independently of the cooling section. The optimal temperature for the freezer is -18°C.
Some models may activate these functions automatically after the door has been open for an extended period or when a large amount of new food is added, in order to quickly restore the optimal temperature.
Yes, this is part of the automatic defrost cycle. The water runs down into a drain hole and evaporates. Make sure the drain hole is not clogged.
This is not an error. The alarm indicates that the internal temperature has not yet reached the set level. Once the refrigerator cools down sufficiently, the alarm will turn off automatically.
The alarm can also indicate other conditions, such as an open door or a power failure. Check the display for a specific error code and consult the manual.
Check that the door is installed correctly and opens to a sufficient angle. The problem may also be due to improperly seated hinges.
Standard baking trays do not fit into most regular refrigerators. Some premium models may have a special compartment or flexible layout that allows for this.
On some models, usually those with two compressors or special features, it is possible to temporarily deactivate one of the compartments. This is not typically possible on standard models.
After transport, especially if it was not kept upright, it is recommended to let the appliance stand idle for 4–6 hours, ideally up to 24 hours, before plugging it into the power outlet.
On most models, the door must be opened more than 90° to comfortably remove the internal shelves and drawers. You can find precise information in the product's technical specifications.
