Modern two-chamber units from the Korean brand Samsung are often equipped with advanced temperature control systems, but users may find it necessary to isolate a certain area. Disconnecting the upper chamber This may be required for various reasons: from saving energy to defrosting or storing things that do not require refrigeration. In most cases, we are not talking about a physical shutdown, but about transferring the operating mode to a state where the cold stops being pumped into this compartment.
It is important to understand that structurally Samsung refrigerator is a single refrigerant circulation system. It is technically impossible to completely “turn off” the freezer, leaving the lower section working, without interfering with the circuit, which is a gross violation of the operating rules. However, there are standard methods for stopping the cold supply or switching the device to a special mode, which we will describe in detail.
Before you begin manipulating the control panel, you need to assess the situation. If your goal is energy saving with an empty upper compartment, it will be enough to simply set the minimum temperature or use the “Eco” mode. If a complete stop is required, the algorithm of actions will depend on the type of control of your model: touch panel, mechanical controls or a mobile application.
Design features of dual-chamber Samsung models
Technology Samsung based on the system No Frost, where cold air is forced by a fan from the evaporator into the chambers through special channels. In two-compartment models, the top part is usually the freezer part and the bottom part is the refrigerator part. Air flows are controlled by dampers and sensors. When you try to “turn off” the top, you are actually trying to stop the fan or close the damper, which is rarely done using standard methods.
There are models with a single compressor and a dual-circuit cooling system, as well as simpler versions. In the first cases, the temperature zones are more independent, but still connected by a common refrigerant. Electronic control allows you to flexibly configure parameters, but does not give a “full stop” command for one of the chambers, as this can lead to defrosting of the evaporator and damage to the compressor.
Some Users confuse turning off the camera with Vacation mode. This mode actually stops the operation of the refrigerator compartment (usually the bottom one), but the freezer (top one) continues to work so that the food does not spoil. If you need the opposite - leave the bottom and turn off the top - the standard “Party” or similar mode is not provided in household models. Samsung not provided.
⚠️ Attention: An attempt to physically turn off the fan or sensor in the upper chamber may lead to an error in the self-diagnosis system and block the operation of the entire unit. Use only software settings methods.
Software methods for stopping the cold supply
If your task is to stop freezing food in the upper compartment, the safest way is to change the temperature setting. On the control panel Samsung find the button Freezer (Freezer). By pressing it, set the maximum possible temperature, usually this value -15°C or -14°C. This will not stop the camera completely, but will significantly reduce the intensity of work.
In models with the Smart Control function, control becomes even more flexible. Through the application SmartThings you can track the temperature in real time. Although there is no direct “Turn off the camera” button, you can use scripts or simply set the gentle mode remotely. This is especially convenient if you left and remembered that the upper chamber is empty.
Another option is to activate the Fast Freeze (Fast freezing) mode for a short time and then turn it off. Paradoxically, after operating in this mode, the system may not turn on the compressor for longer, as it will accumulate a large supply of cold. However, this is a temporary solution. For long periods of inactivity, it is better to consider defrosting.
- 🌡️ Set the temperature in the upper chamber to the lowest possible value (for example, -14°C).
- 📱 Use the application SmartThings to remotely monitor and change parameters.
- ❄️ Avoid loading new products so as not to provoke the compressor to turn on.
- 🔌 Consider completely disconnecting the device from the network if the upper chamber is not needed for a long time.
Using the "Vacation" mode and its limitations
Many owners are looking for a way to turn off the top part, relying on the mode Holiday Mode (Vacation). It is important to be clear right away: in technology Samsung this mode is designed to turn off refrigeration the (lower) chamber to prevent mold and odor from forming in the empty compartment while the freezer continues to operate. An attempt to use this mode to turn off the top will not work.
The Vacation mode is activated by long pressing the corresponding button (often indicated by a palm tree icon or inscription Holiday). An indicator lights up on the display and the temperature in the lower compartment is fixed at +15°C. The upper chamber (freezer) continues to freeze as normal. This confirms that separate software shutdown of the freezer when the bottom is running is not implemented by the manufacturer.
Why is this done? Engineers Samsung assume that defrosting the freezer while the refrigerator is running will lead to spoilage of the food below due to a disruption in heat exchange or excess heat from a compressor running idle. In addition, in systems No Frost periodic operation is necessary to defrost the evaporator, even if you are not freezing food.
Why can't you just unplug the power cord for one camera?
Most Samsung models do not have a separate cord for each camera. Inside there is one compressor that drives freon through two circuits or one common one. It is impossible to physically separate their power without opening the case and breaking the wiring, and this will void your warranty.
Physical shutdown and technical nuances
If software methods are not suitable and you need to physically shut down the operation of the upper compartment (for example, to use its volume for storage), the only solution is to completely defrost and disconnect the device from the network. Any attempts to block the air supply channels inside the chamber will lead to breakdown circulation system.
There is a myth that you can seal the cold air supply holes in the upper chamber. This is strictly forbidden. In units Samsung with a system Twin Cooling or similar, disruption of the air flow causes overheating of the fan motor and failure of the temperature sensors. The system will perceive this as a malfunction and go into error.
If you nevertheless decide to use the upper chamber as a cabinet, the algorithm of actions is as follows:
- Completely defrost the refrigerator, disconnecting it from the power supply for 24 hours.
- Wipe the internal surfaces thoroughly and leave the doors open for ventilation.
- When turning on, do not load food into the upper compartment so as not to waste energy.
- Set the minimum freezing power to minimize the formation of ice if complete shutdown is not possible.
⚠️ Attention: Using the upper compartment of the freezer for storing things when the refrigerator is turned off is only possible subject to regular ventilation, otherwise mold will quickly grow inside due to residual moisture in the insulation.
☑️ Preparing the upper chamber for use as a cabinet
Comparison of models: Digital Inverter versus conventional compressor
Temperature control capabilities depend on the type of compressor installed. Models with Digital Inverter allow you to more accurately calibrate the work, smoothly changing power. In such refrigerators Samsung it is easier to achieve minimum energy consumption with minimal load on the upper chamber, simply by setting high temperature values.
Conventional compressors operate in “start-stop” mode. If you set the upper chamber to -14°C, the compressor will turn on less often, but when started it will work at full power, quickly freezing the volume. Inverter models in this regard are more economical and more gentle on products (if any) at partial load.
Below is a table showing the differences in temperature control for different types of systems:
| Characteristics | Digital Inverter | Conventional compressor | Two-compressor (rarely) |
|---|---|---|---|
| Adjustment accuracy | High (1°C step) | Average | Independent |
| Noise during operation | Low | Medium/High | Average |
| Reaction to an empty chamber | Reduced speed | Rare switching on | Circuit shutdown |
| Energy saving | Up to 50% | Basic | High |
Typical user mistakes when setting up
When trying to turn off the upper chamber, users often make mistakes that lead to breakdowns. One of the most common is an attempt to “deceive” the temperature sensor by heating it with a hairdryer or a warm object. The system Samsung will regard this as a sensor malfunction and display an error code (for example, 22C or 26E), after which the refrigerator may go into emergency mode or stop freezing altogether.
Another error is sealing the ventilation holes with foil or with tape. This upsets the pressure balance within the system No Frost. The fan begins to work with overload, which reduces its resource. In addition, cold air will still penetrate through the leaks, but uncontrollably, causing the formation of condensation and ice in unexpected places.
You should also not change the settings back and forth often. Electronics Samsung needs time (from 30 minutes to several hours) to stabilize the temperature after each change. Frequent switching of buttons will not allow the system to enter the mode, and the compressor will work continuously, trying to execute conflicting commands.
- 🚫 Do not seal the ventilation holes inside the chamber.
- 🌡️ Do not artificially heat the temperature sensors.
- ⏱️ Give the refrigerator a minimum 2 hours for stabilization after setup.
- 📖 Read the instructions for the specific model, as the interfaces may differ.
⚠️ Attention: Control panel interfaces may differ depending on the year of manufacture and series of the refrigerator. If the buttons described do not match yours, check the official user manual for your specific model.
Frequently asked questions (FAQ)
Is it possible to completely turn off the freezer while leaving the refrigerator running?
No standard means. The design of single-compressor refrigerators Samsung does not provide for independent shutdown of the freezing circuit. The refrigerator will either work completely or not work at all. The “Vacation” mode turns off only the refrigeration (lower) chamber.
What will happen if you keep the door of the upper chamber open?
The system No Frost will begin to actively push warm, moist air inside, which will lead to freezing of the evaporator and the formation of a “fur coat”. The compressor will work non-stop, trying to compensate for heat loss, which can lead to overheating and breakdown.
How to save electricity if the upper chamber is not used?
The best way is to completely defrost the refrigerator, unplug it, dry it and keep the doors ajar. If you need the lower part to work, simply do not load the upper part with food and set the minimum freezing temperature there.
Why does it not change immediately after setting the temperature?
The refrigerant and the system need time to redistribute temperatures. In refrigerators Samsung the stabilization cycle can take up to 12 hours. Do not change the settings again during this period, so as not to disrupt the algorithm of the electronics.
