How to adjust the temperature in a Bosch refrigerator: a detailed guide

Refrigerators Bosch is famous for its reliability and intelligent control systems, but even the most advanced equipment requires proper configuration. Incorrectly selected temperature conditions lead to overfreezing of food, excessive energy consumption, or, conversely, insufficient cooling. In this article, we will look at how to regulate the temperature in refrigerators Bosch of different series - from mechanical models with rotary knobs to modern devices with touch controls and systems. VitaFresh.

You will learn what values ​​are considered optimal for the main chamber and freezer, how to reset the settings to factory settings if the refrigerator starts to work incorrectly, and what to do if the temperature does not match the set one. We will pay special attention to the nuances for models with NoFrost, LowFrost and freshness zones - their settings have their own characteristics.

Important: parameters may differ depending on the year of manufacture and series of the refrigerator. If your model was released before 2018, check the relevance of the recommendations in the user manual - some older devices do not support modern adjustment algorithms.

Optimal temperature conditions for a Bosch refrigerator

The manufacturer recommends maintaining a temperature in the main chamber from +2°C to +5°C, and in the freezer - from −18°C to −24°C. However, these values may vary depending on:

• 📦 The load of the chambers —the more products, the colder the mode should be;
• 🌡️ Room temperatures —in hot weather the refrigerator works more intensively;
• 🍎 Type of stored products —meat and fish require lower temperatures than fruits;
• ❄️ Cooling technologies —models with NoFrost usually maintain a more stable climate.

For freshness zones (if your model has them), the optimal values are:

• 🥬 VitaFresh for vegetables/fruits: 0°C…+2°C (high humidity);
• 🥩 VitaFresh for meat/fish: −1°C…0°C (low humidity).

Exceeding the recommended values leads to spoilage of food, and underestimation leads to an increase in ice (in models without NoFrost) and compressor overload. In Bosch refrigerators with the system SuperCooling a short-term decrease in temperature to +1°C speeds up the cooling of fresh food, but this mode should not be turned on constantly.

How to adjust the temperature in mechanical models

Refrigerators Bosch with mechanical control (for example, series KGN33VL30 or KGN36XL30) are equipped with rotary controls, usually located inside the main camera on the top panel or on the side. To change the temperature:

1. Find the regulator - it can be labeled as Thermostat, Temp or simply have a scale from 1 to 7.
2. Turn the knob clockwise to decrease in temperature (increase the cold), against - to increase it.
3. Wait 6-8 hours for the temperature to stabilize, then check it with a thermometer.

In mechanical models, the scale often does not have precise degree indications. Focus on the following correspondences (for most devices):

⚠️ Attention: In models with one regulator for both chambers (for example Bosch KGN33NW20), changing the temperature in the main compartment automatically affects the freezer. If you need independent control, look for devices with separate adjustment (two handles).

Setting up electronic and sensory Bosch refrigerators

Modern models (series KAN92VI30, KGN39VL35, KAD92SB30 etc.) are equipped with electronic control with a display or touch buttons. Setting algorithm:

1. Press the button Menu or Settings (depending on the model).
2. Select section Temperature or Cooling (maybe be called Fridge for the main chamber and Freezer for the freezer).
3. Set the values using the buttons +/− or the touch slider.
4. Confirm the selection (button OK or touch on the screen).

In some models (for example, Bosch KAN92VB35) additional options are available:

• 🌬️ SuperCooling — accelerated cooling to +2°C (automatically turns off after 6 hours);
• ❄️ SuperFreezing — intensive freezing down to −30°C (for freezer);
• 🍏 VitaFresh —separate adjustment of freshness zones.

For models with a display on the door (for example, Bosch KAD92SB30), the temperature is displayed in real time. If the readings do not change after adjustment, check:

• 🔌 Connection to the electrical network;
• 🚪 Door closure tightness;
• 📶 The functionality of the sensors (if a breakdown occurs, an error may appear on the display E01 or F02).

Features of adjustment in refrigerators with NoFrost and LowFrost

Models with the NoFrost system (for example, Bosch KAN92VI30) automatically defrost and maintain a stable temperature due to forced air circulation. Their setting has nuances:

• 🌀 The fans work constantly, therefore you cannot block the back wall products - this disrupts air exchange;
• ❄️ The temperature in the freezer is distributed more evenly, but when opening the door it takes longer to recover;
• 🔄 Mode SuperFreezing turn on 24 hours before loading a large volume of food.

In refrigerators with LowFrost (for example, Bosch KGN39VW35) ice formation is minimal, but manual defrosting is still required 1-2 times a year. The same setting rules apply for them. for NoFrost, but:

• 📉 The temperature in the lower part of the freezer can be 1-2°C lower than in the top;
• 🕒 After adjustment, stabilization takes up to 12 hours.

⚠️ Attention: If in the refrigerator s NoFrost ice has appeared on the back wall of the main chamber, this may indicate a malfunction of the defrosting system or door seal. Do not try to scrape off the ice - contact service.

What to do if NoFrost stops working?

If the fan in the freezer does not make noise and the temperature rises, check:

1) Whether the food is blocking the air duct in the back;

2) Whether the backlight works when the door is opened (if not, there is a power problem);

3) Are there any errors on the display (codes E22 or F24 indicate a breakdown of the defrosting system).

In this case, diagnostics by a technician is required - independent repairs can lead to failure of the electronic unit.

How to reset the temperature settings to factory settings

If the refrigerator Bosch started does not work correctly (for example, it freezes too much or does not cool), sometimes resetting the settings helps. The method depends on the model:

For mechanical refrigerators:

1. Turn the temperature regulator to position 0 (or Off).
2. Unplug the refrigerator for 10-15 minutes.
3. Turn on and set the regulator to middle position (usually 3–4).

For electronic models:

1. Hold the button Menu (or Settings) for 5-10 seconds until the message appears Reset.
2. Confirm reset (button OK or touch).
3. After a reboot (1-2 minutes), set the temperature again.

In some devices (for example, Bosch KAD92SB30), the reset is performed through a combination of buttons:

Press [SuperCooling] + [SuperFreezing] simultaneously for 8 seconds.

⚠️ Attention: Factory reset deletes all user settings, including modes VitaFresh and timers If the refrigerator is connected to the application Home Connect, you may need to reset. synchronization.

Frequent errors when adjusting the temperature

Many users encounter problems due to incorrect actions. Let's look at typical errors and their consequences:

Another common problem is inconsistency. set and actual temperatureCauses:

• 🔧 Faulty thermostat or sensor;
• 🧊 Clogged capillary tube (flushing required);
• 🔌 Voltage surges in the network (solved by installing a stabilizer).

How to check the accuracy of the temperature without a thermometer

If you don’t have a special thermometer for the refrigerator at hand, you can estimate the temperature using improvised means:

1. Water test: place a glass of water in the main chamber for 2-3 hours. If the water is covered with a thin crust of ice, the temperature is below +2°C; if it’s just very cold, it’s about +4°C.
2. Test with butter: put a piece of butter on a saucer. If it is hard as a stone - in the chamber below +3°C; if it is easy to cut with a knife - about +5°C; if it has softened - above +6°C.
3. Control by product:
   • 🥛 Milk turns sour faster in less than 3 days - the temperature is above +5°C;
   • 🍌 Bananas turn black in a day - below +2°C;
   • 🧀 Cheese becomes moldy within week - the humidity or temperature is too high.

For the freezer:

• ❄️ If the ice in the molds melts in 12 hours - the temperature is above −18°C;
• 🍦 The ice cream becomes soft - the mode is above −16°C;
• 🥩 The meat is covered with an ice crust thicker than 1 cm - the temperature is too low (below −24°C).

⚠️ Attention: These methods give approximate results. For accurate diagnosis (for example, if a breakdown is suspected), use a digital thermometer with an external sensor or contact a service center.

FAQ: Frequently asked questions about adjusting the temperature in Bosch refrigerators

Is it possible to turn off the freezer in a two-chamber Bosch refrigerator?

In most models, the freezer cannot be turned off - it works synchronously with the main chamber. The exception is some devices with an independent one. controls (for example, Bosch KAN92VB35), where you can set the freezer temperature to −8°C (minimum mode). Complete shutdown is possible only in the event of a breakdown or if you remove the plug from the socket.

Why does the Bosch refrigerator constantly work and does not turn off?

The reasons may be be as follows:

• The temperature is set too low;
• The room is hot (above +30°C);
• The door does not close tightly;
• The thermostat or sensor has failed;
• Freon leak.

First check the settings and seals. If the problem persists, call a technician.

How often do you need to defrost a Bosch refrigerator with NoFrost?

Technically, defrosting is not required, but once a year It is recommended:

1. Turn off the refrigerator;
2. Wash all shelves and containers;
3. Wipe the seals;
4. Leave the doors open for 1-2 hours to ventilate.

This removes accumulated odors and maintains hygiene.

What to do if error E01 or F02 flashes on the display?

These codes indicate problems with temperature sensors:

• E01 —the main camera sensor is faulty;
• F02 —a problem with the sensor freezers.

Try to turn off the refrigerator for 10 minutes. If the error remains, you need to replace the sensor.

Can a Bosch refrigerator be used on an unheated balcony in winter?

No. data-i="253">. In cold weather: from +10°C to +43°C. In the cold:

• The oil in the compressor thickens;
• Electronics may fail;
• Seals lose elasticity.

If you need to store food in a cold room, choose models with a climate class SN-T (for example, Bosch KSV33VW30), operating up to +10°C.
