How disable the upper chamber of the Samsung refrigerator

Modern refrigerators Samsung series No Frost are often equipped with a dual-circuit cooling system, where the upper and lower chambers can operate at different temperatures modes or independently of each other. Users often find it necessary to change the settings of the top section to switch it to vegetable storage, defrosting mode, or to save energy. Understanding the logic of operation electronic control is the first step to proper operation of the device.

In most cases, “turning off” does not mean physically de-energizing, but switching the camera to a special operating mode, for example, Cool Select+ or Power Cool. Incorrect control may result in food spoilage or excessive condensation. In this material we will analyze software configuration methods and technical aspects of the circulation system circulation systems.

It is important to immediately note that the design of your unit may differ depending on the year of manufacture and series. Control panel interfaces change, so the visual layout of the buttons may vary. Physically turning off a fan or damper without understanding the wiring diagram may result in permanent damage to the control board. Always consult official documentation before tampering with electronics.

Operation principle Samsung dual-circuit cooling

Refrigerators of the South Korean brand often use the technology of separate cold air supply. In such models, the temperature in the upper compartment is controlled by a separate evaporator or system of dampers that redistributes flows from a common compressor. The electronic module reads sensor readings and regulates the operation of motor-compressor and fans.

When you change the settings on the panel, you send a signal to the controller to change the operating algorithm. For example, when selecting the “Vegetable Storage” mode, the system reduces the cooling intensity in the upper zone, preventing moisture from freezing. This is not a complete shutdown, but a change temperature threshold the thermostat response.

⚠️ Attention: Models with one compressor cannot completely turn off the cooling of one chamber while the other is running, since the refrigerant circulates through a single circuit. Complete isolation is only possible in models with two compressors, which are rare.

Understanding this physics of processes helps to avoid mistakes. If you try to “turn off” the upper chamber on a single-circuit model, the system will simply stop supplying cold air there, but the temperature there will begin to rise to room temperature, which may be unsafe for some products.

Software shutdown via the control panel

The most common way to change the operating mode of the upper chamber is to use the functionality Cool Select+ (or a similar name like Flex Zone). This mode allows you to independently regulate the temperature in the upper compartment, essentially “turning off” its standard freezing or deep cooling mode.

To activate, you need to find the button with the corresponding name on the control panel. Pressing this button switches the operating modes of the upper section. The usually available options are: "Meat/Fish", "Vegetables/Fruit", "Cool" and "Defrost". Selecting the “Defrost” or “Off” mode (if available in your model) stops the cold supply.

• 🔹 Find the button Cool Select+ or Upper Fridge on the front panel.
• 🔹 Press the button until the indicator indicates the desired mode (for example, "Off" or the icon of a crossed out snowflake).
• 🔹 Confirm the choice if the model requires an additional button press Freeze or Confirm.
• 🔹 Wait 10-15 minutes for the temperature inside the chamber to stabilize.

After changing the settings the refrigerator may make sounds of flowing refrigerant or clicking sounds - this works normally, redirecting the flow of freon. Do not be alarmed by these sounds, they indicate the correct operation of the system. solenoid valve, redirecting freon flows. Do not be afraid of these sounds; they indicate the correct operation of the system.

Using Smart Control and Wi-Fi mode

Modern models Samsung support remote control via the application SmartThings. This allows you to disable or change the top camera mode directly from your smartphone, anywhere in the apartment. The functionality of the application is often wider than that of the physical panel.

In the application menu, select your refrigerator, go to the zone management section. There you can see more detailed settings, including precise temperature settings or full power saving mode. This is especially convenient if the control panel on the refrigerator itself is located high or inconveniently.

If communication is lost, the last set settings are saved in the device memory and continue to be executed.

What to do if the application does not see the refrigerator?

Make sure that the module Wi-Fi is turned on on the refrigerator itself (usually by holding the Wi-Fi button for 3 seconds). Check if the 2.4 GHz network is working, as Samsung refrigerators often do not support 5 GHz. Reboot the router and try pairing again.

Vacation mode: completely turning off the refrigerator compartment

If your goal is to leave for a long time and leave only the freezer on, you will need the Vacation (Vacation) mode. In this state, the upper refrigerator compartment is actually turned off: the light in it will not light up, ventilation stops, and the temperature rises to +15..+17°C.

This prevents the appearance of mold and unpleasant odors in an empty refrigerator, while allowing frozen food to be stored in the lower compartment. The mode is usually activated by long pressing the button Freeze or a separate button with the image of a palm tree/suitcase.

⚠️ Attention: Before turning on the holiday mode, be sure to remove all perishable products from the upper chamber and thoroughly wipe the shelves. Left food at a temperature of +15°C will quickly spoil.

In some models, to enter this mode you need to press a combination of buttons, for example, Freeze and Cooling simultaneously for 3 seconds. The indicators may go out or light up in a specific color, signaling the transition to sleep mode.

Diagnostics: when the chamber does not cool due to a malfunction

The situation when the upper camera does not work can be not only the result of the settings, but also a sign of a breakdown. If you have not set energy saving modes, and the cold has disappeared, you need to carry out system diagnostics. Often the problem lies in freezing of the air supply channel.

In models No Frost moisture from the products is removed through the drainage hole. If it becomes clogged with ice or debris, air stops circulating and the upper chamber stops cooling, although the compressor is running. Failure of temperature sensor or the fan is also possible.

• ❄️ Check that the ventilation holes inside the chamber are not blocked by products.
• ❄️ Listen to whether the fan is working (hum or whistle from the back wall).
• ❄️ Inspect door seal for damage allowing warm air to pass through.
• ❄️ Pay attention to the error code on the display (for example, 22E, 24E - sensor errors).

If you find ice at the top of the back wall, you may need to completely defrost the refrigerator within 24 hours with the doors open. This will help eliminate the ice plug in the air channel.

Technical limitations and resetting settings

Sometimes a software failure can block the ability to change settings. In this case, resetting to factory settings helps. To do this, on most models Samsung you need to hold the Freeze and Cooling (or Energy Saver) buttons simultaneously for 5-10 seconds.

After the reset, the refrigerator will reboot and all user settings, including temperature conditions will return to standard values. This may "wake up" the top camera if it was software frozen. However, if the problem is of a technical nature, resetting will not help.

It is important to consider that frequent temperature changes and on-off cycles reduce the resource compressor. It is not recommended to use the upper chamber shutdown modes as the main method of storing food on a permanent basis, unless it is directly necessary.

Why does the upper chamber not turn off completely?

Most Samsung household refrigerators use a single-circuit system. This means that it is physically impossible to stop the flow of cold into one chamber while another is running, without the use of special valves that only block the flow, but do not seal the volume hermetically. Heat exchange through the partitions will still occur.

Is it safe to keep the refrigerator in the "Vacation" mode for a month?

Yes, this is the normal operating mode, designed for long periods of inactivity. The main condition is the absence of products in the warm zone. The compressor will turn on rarely, only to maintain the temperature in the freezer, which saves energy.

What does a flashing temperature indicator mean?

Flashing numbers usually indicate that the temperature inside the chamber is higher than the set norm. This happens immediately after switching on, after defrosting or loading a large amount of warm food. If the blinking does not stop after 2-3 hours, check that the door is tightly closed.
