How to turn off only the freezer in the refrigerator Bosch

Modern household appliances, such as Boschare often equipped with sophisticated electronics that allow flexible control of temperature conditions. However, in some life situations it becomes necessary to completely or partially change the functionality of the device, for example, by turning off the freezer in order to use it as an additional refrigeration compartment or simply for defrosting. Users often wonder whether this can be done programmatically without unplugging the cord from the outlet, and which buttons need to be pressed to activate the desired mode. It is important to note right away that the design features of the models may differ significantly. While some refrigerators have a separate cooling circuit for the freezer, others operate on a single refrigerant, where complete shutdown of one compartment is physically impossible without stopping the compressor. Understanding how your model works

It is important to immediately note that the design features of the models Series 4, Series 6 or Series 8 may differ significantly. While some refrigerators have a separate cooling circuit for the freezer, others operate on a single refrigerant, where complete shutdown of one compartment is physically impossible without stopping the compressor. Understanding how your model works NoFrost or LowFrost is a key first step before you begin any manipulation of the settings.

This manual will help you understand the nuances of operation and tell you how to safely change the temperature setting. We will consider both software methods through the control panel and mechanical methods applicable to different generations of equipment from the German brand. Compliance with the sequence of actions guarantees the safety of the products and the serviceability of the unit.

Principles of operation of the Bosch cooling system

To understand how to turn off the freezer, you need to understand principle of the compressor. Most models of refrigerators Bosch with the system NoFrost use one compressor that drives cold air through both circuits. Electronics regulate the dampers, directing the air flow. If you raise the temperature in the freezer to the maximum, the compressor may stop turning on if the temperature in the refrigerator compartment has already been reached, but this depends on the algorithms of the specific control board.

In models with two compressors (which is less common in budget and mid-range series), the situation is simpler. Here you can control each circuit independently. However, even in single-circuit systems, modern controllers allow you to switch the freezer to the “vacation” mode or simply increase the temperature to +5...+7°C, turning it into a refrigeration compartment. The key point here is air circulation and the absence of ice jams.

⚠️ Attention: Do not try to physically cut the wires or block the temperature sensors. This will lead to failure of the electronics and loss of warranty.

The electronic control system Bosch constantly monitors sensor readings. If you force changes to the settings, the system will try to compensate for the changes, which may result in increased power consumption. Understanding exactly how your Bosch distributes cold will help you avoid mistakes. In some older models without an electronic display, it is impossible to programmatically turn off the freezer.

Technical features of single-circuit systems

In single-circuit refrigerators, the refrigerant passes first through the freezer chamber and then through the refrigeration compartment. Therefore, completely “turning off” the cold in the freezer, leaving it in the refrigerator, is technically difficult without special valves controlled electronically.

Software shutdown via the control panel

The safest and most correct way to change the operating mode is to use a standard control panel. In models with a display (for example KGN series), you need to find the button responsible for setting the freezer temperature. It is usually indicated by a snowflake symbol or a letter F. By clicking on it, you will see flashing numbers indicating the current temperature.

Your task is to increase the temperature value to the maximum possible. Depending on the model, this may be -6°C, 0°C or even +10°C (chiller mode). Once you set the desired value and stop pressing the buttons, the settings will be saved after a few seconds. The compressor will begin to operate in a new mode, gradually increasing the temperature in the chamber.

• 🔹 Find the freezer temperature setting button on the display.
• 🔹 Hold or press the button until the flashing indicators appear.
• 🔹 Set the maximum temperature value (usually from -6°C to +10°C).
• 🔹 Wait until the blinking stops, which means saving the settings.

If your refrigerator Bosch does not have a display, but only mechanical controls or simple buttons SuperFrost, you will not be able to programmatically turn off the freezer. In such cases, a change in temperature is only possible in the general circuit, which will also affect the refrigeration compartment. Always check the instructions for the specific model, as the logic of the buttons may differ.

Using the "Super Freeze" and "Vacation" modes

Many users confuse the functions without understanding their purpose. The SuperFrost mode is designed for quick freezing of fresh food and maximum lowers temperature, which is the opposite of our goal. However, knowing how this mode is activated and deactivated is useful for complete control over the device. Usually it turns off automatically after a certain time or manually by pressing it again.

More interesting is the "Vacation" mode (often indicated by a palm tree or suitcase symbol). In this mode, the refrigerator Bosch switches the refrigerator compartment to economy mode (about +15°C) to prevent the formation of mold, while the freezer continues to operate. We need the opposite. Unfortunately, there may not be a standard “fridge only” function in the menu, but we can emulate it by setting the temperature in the freezer to +5...+7°C, if the model allows it.

⚠️ Attention: Long-term storage of food at temperatures above -18°C in the freezer is dangerous to health. Use this mode only for short-term storage of vegetables or drinks.

In some advanced models with the function HomeConnect temperature control can be done via an application on a smartphone. This provides more flexible configuration and monitoring options. You can precisely set the temperature in 1-degree increments, watching in real time how the climate inside the chamber changes. This is especially convenient for precise calibration for storing specific products.

Mechanical methods and adjustment of dampers

In models without electronic control or with a minimalist interface, the only way to influence the temperature is mechanical adjustment. Inside the refrigerator compartment, often on the back wall or at the top, there may be a damper that regulates the flow of cold air from the freezer. By turning it off, you will reduce the cold in the refrigerator, but this will not turn off the freezer itself.

There is a myth that you can seal the temperature sensor in the freezer to “deceive” the refrigerator. Do this strongly not recommended. If the sensor in the freezer shows a falsely high temperature, the compressor will run continuously, trying to cool the chamber. This will lead to freezing of the evaporator, overheating of the motor and possible defrosting of food in the main compartment due to imbalance.

If your goal is simply to free up space rather than change the temperature, consider using divider containers. However, if it is technically necessary to stop the freezing process (for example, to store watermelon in winter), it is better to use the modes provided by the manufacturer. In older models Bosch with a thermostat knob (from 0 to 7), setting to 0 means turning off the compressor, that is, completely turning off the entire refrigerator.

Features of models with the NoFrost and LowFrost system

System NoFrost implies the absence of ice due to the constant circulation of dry cold air. In such refrigerators Bosch the evaporator is often hidden, and the air is pumped by fans. If you increase the temperature in the freezer programmatically, the fan will continue to circulate air, but it will be warmer. This can lead to the fact that the products in the refrigerator compartment also heat up if the system is not divided into independent circuits.

In systems LowFrost (often found in built-in models and
