Use the space in your kitchen efficiently with the BOSCH KGN39AIAU Serie 6 combi fridge freezer, which you can place anywhere. The appliance needs no extra space around it, so you can easily place it right next to a wall or close to furniture or your kitchen units. The entire refrigerator compartment of the BOSCH KGN39AIAU Serie 6 is illuminated by energy-saving, anti-glare LED bulbs. Thanks to 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 is not warmed up when new food is added.

Bosch fridge freezers combine the highest energy efficiency and exceptionally quiet operation in class A. They deliver reliable performance, optimal food preservation conditions and stand out for their low noise levels during daily operation.
Uneven cooling can negatively affect the taste and shelf life of food. Bosch fridges with Multi Airflow technology ensure an even distribution of moisture and temperature throughout the entire space–from the door compartments to the back corners. Your food stays fresh and tasty for longer.
The spacious VitaFresh XXL drawers in the BOSCH KGN39AIAU Serie 6 fridge freezer 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, there's no need to defrost the freezer regularly. The system removes moisture and keeps the air dry, which limits the formation of frost on the freezer walls and on your food. The same principle also works in the fridge compartment, where it helps prevent water droplets and frost from forming on the back wall. This makes maintenance easier and ensures the appliance maintains its high energy efficiency.
Say goodbye to noise – Bosch Noise Class A fridges operate extremely quietly, with a noise level of just 29 dB. Ideal for open-plan spaces and undisturbed peace. Experience the kind of quiet that brings comfort.
The BOSCH KGN39AIAU Serie 6 fridge has been designed so you can place it absolutely anywhere. The PerfectFit technology allows you to position the fridge as you wish, for example, against a side wall or directly next to furniture, with no gap needed. You are no longer limited by a lack of space. The BOSCH KGN39AIAU Serie 6 fridge is particularly suitable for those who don't want a built-in fridge but wish to make the best possible use of their kitchen unit space.
If you forget to close the fridge door or don't close it fully, you will be alerted by a light and an acoustic signal after a short time. The BOSCH KGN39AIAU Serie 6 will also let you know in the same way if any other error occurs.
LED lighting ensures the interior of the fridge is evenly illuminated. Compared to standard bulbs, it consumes less energy and has a longer lifespan.
The freezer and fridge sections in the BOSCH combination fridge each have their own circuit. This means the temperature can be set individually for each.
Activating the super cooling or super freezing function will very quickly cool/freeze food that has just been placed in the BOSCH KGN39AIAU Serie 6 appliance. The function prevents food already in the fridge from warming up, ensuring it stays fresh for longer.
The front of the BOSCH KGN39AIAU Serie 6 fridge is treated with a special permanent surface 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.
