Situations when owners of modern kitchen appliances need to change the standard operating mode of the unit arise quite often. The question of how to turn off the freezer in a Bosch refrigerator becomes relevant when there is no need to freeze food for a long time or during defrosting. Owners of models Bosch Serie 4 or older lines often look for ways to isolate the upper chamber in order to use the device exclusively as a refrigerator compartment.
It is necessary to immediately clarify an important technical nuance. In most modern models with a NoFrost or LowFrost system, it is structurally impossible to completely and independently turn off the freezer compressor, leaving only the refrigeration compartment to work. The cooling system is often shared or interconnected, so completely “turning off” one zone without affecting another may not be available through the standard menu.
However, there are effective ways to minimize the energy consumption of the freezer or put it in minimum load mode. In this article we will analyze all the available methods for controlling temperature conditions, from setting up the electronic display to physically turning off the power if absolutely necessary. Understanding the logic of your Bosch KGN or KGV will help you avoid mistakes.
Design features of Bosch refrigerators
The engineering philosophy of the German brand Bosch involves a high degree of integration of cooling systems. In models with two compressors, independent operation of the circuits is theoretically possible, but such devices are less common and belong to the premium segment. Most household units are equipped one compressorthat drives refrigerant through both circuits.
If your device implements technology MultiAirflow, cold air circulates through all chambers. An attempt to completely shut off the cold supply to the freezer can lead to disruption of the sensors and malfunctions in the main compartment. That is why manufacturers do not provide a standard “Turn off the freezer” button in the control interface.
⚠️ Attention: An attempt to mechanically block the ventilation ducts inside the chamber can lead to overheating of the compressor and failure of the entire cooling system. Use only software configuration methods provided in the instructions.
It is important to consider the type of control of your device. Electronic control allows flexible adjustment of parameters, while electromechanical control (controls with numbers from 1 to 7) gives only approximate control over the overall temperature. In the latter case, there is only one way to “turn off” the freezer - by setting the regulator to minimum or disconnecting the device from the network.
Setting the temperature mode via the control panel
The safest and most correct way to reduce the load on the freezer is to set the maximum permissible temperature within its limits. For most models Bosch the standard range is from -18°C to -24°C. Increasing the temperature to -6°C or -8°C effectively puts the freezer into refrigerator mode.
To perform this operation, you must activate the control panel. This usually requires a short press of the Power or Modebutton. Once the display is activated, use the arrow buttons or touch zones + and - to select the freezer zone (often indicated by a snowflake or symbol **).
- 🌡️ Press the zone select button so that the freezer light flashes.
- ❄️ Use the temperature increase key (usually
+) until the value reaches -6°C or -8°C. - ✅ Confirm the selection without pressing anything for 5-10 seconds, the settings will be saved automatically.
If you set the temperature above -18°C, the display may the warning indicator will light up, indicating that the storage conditions do not meet the standards for long-term freezing. This is a normal reaction of the system, which reminds the user that food may begin to deteriorate. For short-term storage of vegetables or drinks in the upper chamber, this is quite acceptable.
Some advanced models are equipped with a EcoMode or SuperFrost mode (which needs to be disabled). Make sure that the intensive freezing mode is deactivated. In the SuperFrost mode, the compressor operates continuously, ignoring the set temperature thresholds, which leads to the maximum. cooling.
Using the Holiday Mode function
One of the most useful functions for those who want to turn off the active operation of the freezer is the “Vacation” mode (Holiday ModeThis operating algorithm is designed specifically for periods of long absence of owners. Its main purpose is to prevent the appearance of mold and unpleasant odors in an empty refrigerator. with minimal energy consumption.
When this mode is activated, the temperature in the refrigerator compartment rises to +14°C...+15°C. The freezer, depending on the model, either continues to operate in normal mode, or (in some versions with separate circuits) also switches to an economical mode. However, if your goal is to use the upper part as a refrigerator, this mode is ideal for the lower part, and manual operation is required for the upper part. adjustment.
⚠️ Attention: In the “Vacation” mode, the refrigerator door must be tightly closed. If you leave it slightly open for ventilation, the temperature inside will rise to room temperature and the mode will not work correctly.
Activation is done through the settings menu. Find the button with the image of a palm tree or the inscription. Holiday. In models without a separate button, this mode is called by long pressing the button for setting the temperature of the refrigerator compartment. You can find out more about the sequence of actions for your model by entering the model code (E-Nr) on the official website of the manufacturer.
Why is the temperature +15°C in holiday mode?
This temperature was not chosen by chance. It is high enough to save energy, but it is enough. low to prevent the growth of bacteria and the appearance of a musty smell in an empty cabinet. At higher temperatures, mold develops faster.
Mechanical shutdown and physical defrosting
If software methods do not give the desired result or a complete defrosting of the system is required NoFrost for cleaning, you have to resort to radical measures. Complete shutdown of the freezer is only possible by cutting off the power supply to the entire unit or, in rare cases, to a separate circuit (if the wiring and design allows it).
To carry out deep cleaning or repairs, it is necessary to perform a complete defrost. This process takes 12 to 24 hours. Do not try to speed it up with a hairdryer or hot water - this can damage the plastic evaporator and lead to the formation of microcracks in the cooling system.
☑️ Checklist before complete defrosting
During the defrosting process, water will drain into a special tray or onto the floor. Prepare rags in advance. After the ice has completely melted, wipe the internal surfaces with a soft cloth. once all the parts are dry and the temperature inside is equal to room temperature.
| Parameter | Value / Action | Note |
|---|---|---|
| Minimum temperature | -24°C | Mode SuperFrost |
| Maximum temperature | -6°C ... -8°C | Refrigerator mode |
| Defrosting time | 12-24 hours | Depends on the amount of ice |
| Temperature in Holiday mode | +14°C ... +15°C | Refrigerator compartment only |
Problems with sensors and their impact on operation
Sometimes users want to turn off the freezer because it has stopped freezing or, conversely, is freezing too much. In such cases, the problem may lie in a malfunction temperature sensor (thermostat). If the sensor is stuck or transmits incorrect data, the compressor may operate continuously or not turn on at all.
In models Bosch with electronics, the malfunction is often displayed in the form of flashing indicators or an audible signal. For example, a flashing snowflake indicates an increase in temperature above critical. If you are trying to turn off the camera and it does not respond to commands, the sensor module or the sensor itself may need to be replaced.
Diagnosing faults requires special knowledge and tools. Replacing the sensor yourself is possible if you have skills in working with a multimeter and a soldering iron. However, if the device is under warranty, any interference with the electrical circuit will lead to loss of warranty.
Alternative solutions and operation
If your goal is to save energy and not physically turn off the camera, consider filling the free space. It is more difficult to cool an empty freezer than a full one (the heat capacity of food is higher than that of air). Fill the free space with plastic bottles of water or special cold accumulators.
It is also worth checking the door sealing rubber bands. If they do not fit tightly, warm air constantly enters the chamber, causing the compressor to wear out. The test can be carried out using a sheet of paper: clamp it with the door and try to pull it out. If the sheet is removed without effort, the seal requires replacement or adjustment.
In conclusion, it is worth noting that modern refrigerators Bosch are complex devices where all processes are interconnected. Complete software shutdown of the freezer while the main compartment is running is impossible in 95% of models due to the same refrigerant. The best solution remains to set the temperature to maximum (-6°C) or use the device in defrost mode if necessary.
Is it possible to completely turn off the freezer while leaving the refrigerator running?
In most models with one compressor - no. The cooling circuit is the same for the entire volume. Disabling one of the evaporators will disrupt the circulation of the refrigerant. It is only possible to set the minimum temperature in the freezer.
Why does the Bosch freezer not maintain a temperature of -18?
There may be several reasons: a sensor malfunction, a freon leak, a clogged capillary or a loosely closed door. Also check if the SuperFrost mode is turned on, which may interfere with the settings.
How often should you defrost a Bosch NoFrost refrigerator?
The NoFrost system assumes automatic defrosting. Forced defrosting is rarely required (once every 1-2 years) only for hygienic cleaning or in case of breakdown of the water drainage system.
What does a flashing temperature indicator mean?
Flashing indicates that the temperature in the chamber is higher than the established norm. This happens when you turn it on for the first time, after loading a large amount of warm food, or if the cooling system malfunctions.
