Owners of modern household appliances are often faced with the need to temporarily stop the operation of the unit, be it for scheduled cleaning, moving or a long absence of the owners. Refrigerators of the brand Samsung with technology No Frost require a special approach, since their design differs significantly from classic models with a drip defrosting system.
Improper handling of the air conditioner can lead to the formation of an ice plug in the evaporator or failure of the compressor when turned on again. In this article, we will analyze in detail the algorithms of action for various situations, explain the physics of the processes and help you avoid common mistakes when servicing your equipment.
The first thing you need to do is determine the purpose of the shutdown. If you plan to simply unplug the device from the outlet for a few hours to wash it, the procedure will be the same. If transportation or preservation for the winter is required, the actions will be completely different and will require deeper intervention in the operation of the systems.
Preparatory stage before turning off
Before pressing the shutdown button or unplugging the cord from the socket, it is necessary to clear the internal space from the products. Temperature mode inside the chambers will begin to rise immediately after stopping compressor, which can lead to damage to perishable goods. Prepare cooler bags or ice packs in advance for temporary food storage.
It is also important to check for the presence of a forced defrost function in the menu of your device. Many modern models Samsung equipped with electronic control, where you can run a special cleaning cycle. This is true for models with a display on the door, where control is carried out via touch buttons.
⚠️ Attention: If there are glass containers with liquid left on the shelves or drawers, be sure to remove them. As the temperature rises, the contents may expand and the glass will burst, damaging the interior of the chamber.
Remember to turn off additional options, such as the ice maker or water dispenser, if they are integrated into the system. In models with water supply through the door, it is recommended to close the water supply valve on the main line to avoid leaks when releasing pressure in the system after stopping the pump.
☑️ Preparing the refrigerator for shutdown
Shutdown algorithm via the control panel
For models with digital control, the stopping process looks different than simply removing the plug from the network. Electronics Samsung must correctly complete the current cycle of operation of the compressor and fans. On the control panel, find the button Power Freeze or Power Cool —holding these buttons for 3-5 seconds often puts the device into standby mode or turns off cooling completely.
In some series, for example, RB37 or RS69, To completely turn off, you need to simultaneously press the combination of buttons specified in the instructions. The screen will go dark, signaling it has entered sleep mode. This is the most gentle way to stop, allowing the system to save the latest settings and avoid errors in the controller's memory.
If your model is equipped with the function Smart Control and is connected to Wi-Fi, you can use a mobile application to turn off remotely. This is convenient if you have already left home and remembered that you forgot to turn off the device. The app will show the status as "Off" or "Vacation Mode".
Once the electronics are unplugged, it is safe to remove the plug from the outlet. However, if you plan to wash the refrigerator, it is better to first let it stand for 10-15 minutes so that the refrigerant in the system is distributed evenly and the pressure stabilizes.
Physical disconnection from the power supply
When the software shutdown is completed or if your model is controlled by a mechanical regulator, the stage of physically breaking the circuit begins. Power cord for refrigerators Samsung usually quite short, so the use of an extension cord is often required. Make sure your hands are dry before unplugging the plug.
Do not pull on the cord itself, hold only the body of the plug. Sudden jerks can damage the internal contacts or cable braid, which can lead to arcing or short circuiting in the future. If the plug sits very tightly in the socket, gently shake it from side to side to loosen the contacts.
⚠️ Attention: It is strictly forbidden to pull out the plug with wet hands or while standing barefoot on a wet floor. This is a direct threat of electric shock.
After disconnecting from the network, the compressor may make one or more clicks - this is normal, the thermal protection relay is triggered. Do not be alarmed by these sounds, they indicate the normal completion of the electromechanical units.
The process of defrosting the No Frost system
Although the technology No Frost ("no frost") involves automatic removal of moisture, it is impossible to completely eliminate the formation of ice. Over time, ice can accumulate in the hidden passages of the evaporator, which interferes with air circulation. Therefore, complete defrosting at least once a year is necessary.
After turning off, leave the refrigerator and freezer doors open. To speed up the process, you can place a container of hot water inside. Do not use a hair dryer or other heating devices to accelerate the melting of ice - a sudden temperature change can deform plastic elements the inner box or damage the evaporator tubes.
Water will flow into a special tray located above the compressor in the lower rear part of the device. If you plan to wash the floors, it is better to place a large rag or baking sheet under the refrigerator, since the volume of draining water can be significant, especially if a “fur coat” has formed.
The time for complete defrosting takes from 4 to 12 hours, depending on the amount of ice and the temperature in the room. Do not attempt to turn on the appliance until the inside is completely dry. Residual moisture can get on the electrical contacts and cause a short circuit when starting.
Comparison of shutdown methods
The choice of shutdown method depends on your goals. Below is a table that will help you decide on the best course of action for your situation.
| Situation | Recommended method | Downtime duration | Risks |
|---|---|---|---|
| Planned cleaning | Via menu + network | 2-4 hours | Minimum |
| Going on vacation | "Vacation" mode | Up to 30 days | Odor appearance |
| Transportation | Complete shutdown | Week+ | Damage during transportation |
| Emergency situation | Sharp shutdown | Until elimination | High compressor wear |
As can be seen from the table, for short pauses it is better to use standard controls, and for long periods of downtime - a complete physical shutdown. The vacation mode is a compromise that allows you to save energy while maintaining the functionality of the freezer.
Why can’t you turn on the refrigerator immediately after defrosting?
The compressor needs time for the oil that leaked into the circuit during standstill to flow back into the crankcase. If you turn on the unit right away, it will run dry, which will lead to rapid wear and jamming of the piston group. The minimum waiting time is 2-3 hours.
Care and cleaning during downtime
While the refrigerator is turned off and defrosted, it’s time to do some spring cleaning. Use a soft cloth and neutral detergents. Abrasive powders And aggressive chemicals cannot be used, they can damage the antibacterial coating of the chambers. Samsung.
Pay special attention to the rubber seals on the doors. Dirt and mold often accumulate in the folds, which are difficult to remove in working order. Wipe the seals with a soda solution or a special rubber cleaner to maintain their elasticity.
Don't forget to clean the drainage hole if your model has one (usually in the refrigerator compartment on the back wall). To do this, you can use a special brush or soft wire wrapped in cotton wool. Clogged drainage is a common cause of puddles appearing under the refrigerator.
After washing, be sure to wipe all surfaces dry. A humid environment in an enclosed space is an ideal place for bacteria to grow. Leave the doors slightly open until completely dry, even if you plan to turn on the appliance in an hour.
Rules for transportation and long-term storage
If you are unplugging the refrigerator for moving, it is critical to follow the transportation rules. Compressor contains oil, which, when shaken, can get into the refrigerant circuit. It is recommended to transport the unit strictly in a vertical position. Samsung recommended strictly in a vertical position.
⚠️ Attention: If you had to transport the refrigerator lying down, after installing it in a new place, do not turn it on for at least 12-24 hours. The oil must completely drain back into the compressor under the influence of gravity.
During long-term storage (for example, in a country house in winter), the doors should not be left closed. Secure them in the slightly open position with tape or string to ensure ventilation. Otherwise, a musty smell and mold will appear inside, which will then be very difficult to get rid of.
It is also recommended to cover the equipment with a protective cover or thick fabric to prevent dust and insects from getting inside. Before starting for the first time after long-term storage, re-defrost and check all systems, even if the device has only been standing for a couple of months.
Frequently asked questions (FAQ)
Can I turn it off? Samsung refrigerator at night to save energy?
Doing this is strictly not recommended. The compressor is designed to maintain temperature, and not to constantly cycle through complete cooling and heating. Shutting down every day will quickly wear out the start relay and compressor, and also spoil the food. The savings will be negligible compared to the risk of breakdown.
What to do if, after turning on, the refrigerator hums but does not cool?
If you have just defrosted or transported the equipment, wait 2-4 hours. If the problem persists, check that the doors are closed tightly and that the condenser at the back is not clogged. If after 24 hours the temperature does not drop, there may be a freon leak or a compressor breakdown - you need to call a technician.
How to properly wash glass shelves after defrosting?
Do not place cold glass shelves directly under hot water - the glass may burst from thermal shock. Allow them to warm to room temperature, wash with warm water and a mild detergent and dry thoroughly before putting them back.
Do the seals need to be lubricated after cleaning?
Yes, this will extend their life. Use silicone grease or a special rubber conditioner. This will prevent drying out, cracking and loss of elasticity, which is critical for the tightness of the chambers. No Frost.
Why did a whistle or squeak appear after switching on?
In the first minutes of operation after defrosting, a whistle is possible if residual moisture gets on the heating elements or fan. This usually goes away on its own within 10-15 minutes. If the sound persists or increases, check whether the refrigerator is level and does not touch the back wall of the furniture.
