Owners of modern household appliances are often faced with a dilemma: is it really necessary to interfere with the operation of a smart unit if there is an inscription on it No Frost. Two-chamber models Samsungequipped with a full automatic defrosting system theoretically do not require disconnection from the network to remove ice. However, practice shows that even in such devices, over time, ice may form in hard-to-reach places, foreign odors may appear, or cooling efficiency may decrease due to contamination of the air ducts.
If you notice that the door has become worse at closing, and a thin layer of frost has appeared on the inner walls, you cannot ignore this. Forced defrosting is required if the thickness of the ice on the evaporator or walls exceeds 3-5 millimeters, even with the No Frost system. This process is not complicated, but requires adherence to a strict sequence of actions in order to do not damage sensitive electronics or fragile plastic structural elements.
In this article we will analyze in detail the algorithm of actions for models Samsung with different types of control, we will explain why it is not possible use a hairdryer or hot water, and we will answer frequently asked questions about the frequency of the procedure. The right approach will extend the life of the compressor and preserve the freshness of products.
Features of the design and No Frost system
Before taking active steps, you need to understand the operating principle of your device. Most two-chamber refrigerators Samsung use technology No Frostwhich means “no frost”. In such models, a fan constantly circulates dry, cold air through the chambers, preventing moisture from settling on food and walls. The ice that forms on the hidden evaporator automatically thaws during compressor operating cycles.
However, the system is not ideal. Over time, dust, crumbs, and greasy deposits can accumulate in drainage channels, leading to clogs. The water stops flowing into the tray and freezes, forming an ice plug. Ice can also build up if the door is not closed tightly or the seal is damaged. In such cases, the automation cannot cope and manual intervention is required.
It is important to distinguish between models with Full No Frost and those where a drip system is used in the refrigeration chamber (Dry System). In the latter, moisture flows down the back wall, and ice formation there is more likely if the thermostat malfunctions. Understanding the type of your model Samsung will help you choose the right cleaning tactics.
⚠️ Attention: The design of air ducts in different series Samsung may differ. In some models, access to the drainage hole is hidden by a decorative panel that cannot be removed without a tool.
Preparing for the defrosting procedure
The beginning of the process requires careful preparation, since after turning off the equipment you will have limited time to organize food storage. The first step should always be to completely disconnect the device from the electrical outlet. Simply unplugging the plug from the socket is not enough if you have an electronically controlled model - it is better to use the off button, if there is one, and then turn off the power.
Next you need to empty the cameras of their contents. All food should be removed and placed in thermal bags, ice packs or in a cool place (in winter - on the balcony, but make sure that the temperature is not extremely low for some types of food). It is also better to remove empty shelves and drawers to wash them separately with warm water and a mild detergent.
Prepare a place to collect melt water. Cover the floor around with cooling rags or towels. In two-chamber models, the volume of water can be significant, especially if a large block of ice has formed inside. Prepare in advance several containers with a flat bottom that can be placed under the drainage holes.
☑️ Preparing for defrosting
Step-by-step instructions: natural defrosting
The safest and The manufacturer's recommended method is natural thawing. Once you've cleared the chambers and unplugged the unit, simply leave the doors wide open. The process will take from 4 to 12 hours depending on the amount of ice and room temperature. Do not try to speed up this process by mechanical force.
While waiting, ensure that the containers under the drainage holes are filled. Water can drip not only from a special groove, but also flow down the inner walls. If you see that the ice in the freezer Samsung holds very tightly, you can carefully (without effort) try to loosen the ice crust when it begins to thaw and move away from the walls.
After the ice has completely disappeared, you must thoroughly wipe all surfaces dry. Pay special attention to the corners and places where the shelves are attached. A humid environment is an ideal place for bacteria and mold to grow, so keeping the chambers inside dry before turning it on is critical.
How long does defrosting take?
The time depends on the volume of ice and the temperature in the room. Typically the process takes from 4 to 8 hours. If there is a lot of ice (the drainage is clogged), it may take up to 12-14 hours for complete thawing.
What you should absolutely not do
There are many “folk” methods for accelerating defrosting that can cause irreparable harm to your Samsung. The most common misconception is using a hair dryer. Hot air creates a sharp temperature difference, which can lead to cracks in the plastic case, deformation of the evaporator, or damage to internal wiring.
It is also prohibited to use sharp objects (knives, screwdrivers, ice picks) to chip ice. Pipes with refrigerant (freon) in modern models are often located very close to the internal walls or even built into them. One careless blow can pierce the tube, which will lead to a gas leak and expensive repairs from specialists.
It is not recommended to pour boiling water or hot water into the chambers. This can damage the door seals, which, when exposed to high temperatures, will lose their elasticity and no longer seal tightly. In addition, sudden heating of the plastic may cause it to warp.
⚠️ Attention: The use of chemical ice removers or abrasive cleaners is prohibited. They can react with food plastic and make it toxic to products.
Care for the drainage system and fan
Often the cause of the formation of a “fur coat” in the refrigerator No Frost is a clogged drainage. After defrosting, be sure to check the water drain hole (usually located on the back wall of the refrigerator compartment). It should be free. For cleaning, you can use a special brush-brush included in the kit, or a regular soft wire wrapped in cotton wool.
If in your model access to the fan in the freezer is possible (by removing the back panel), check it for the presence of ice build-up on the blades. A frozen fan will not be able to circulate air, causing cooling to stop. Carefully remove the ice and wipe the mechanism with a dry cloth.
To prevent unpleasant odors after washing, you can wipe the internal surfaces with a solution of baking soda or a weak solution of vinegar. This disinfects the chamber and neutralizes odors from old products that may have been absorbed into the plastic.
Completing the process and first launch
When all surfaces are washed and wiped dry, do not rush to load the products right away. Place all shelves and drawers in their proper places. Make sure they are securely fastened. Close the doors and turn on the refrigerator.
Let the device run idle (without food) for 1.5–2 hours. This time is necessary for the compressor to gain the required pressure and for the optimal temperature regime to be established in the chambers. Only after this can you carefully add food, trying not to overfill the chamber at once, so as not to disrupt air circulation.
Pay attention to the operation of the refrigerator in the first hours. It should not make any extraneous sounds, gurgling or knocking. If everything went well, your Samsung is ready for efficient operation again.

Frequently asked questions (FAQ)
How often do you need to defrost a Samsung refrigerator with No Frost?
The manufacturer states that defrosting is not required. However, experts recommend carrying out preventive defrosting and washing once a year. If you notice ice, immediately, regardless of the timing.
Why does the refrigerator not freeze for a long time after defrosting?
You may have turned it on with the doors open or loaded warm food. The cause may also be a freon leak if the circuit was damaged during cleaning. Let the equipment work for 3-4 hours in empty mode.
Is it possible to wash the inside of the refrigerator with water from a hose?
Absolutely not. Water can get into electrical contacts, the thermostat, or behind the casing, causing corrosion and failure. Use only a damp, well-wrung out cloth.
What to do if the water does not go into the drainage hole?
It is necessary to clean the channel. Use a soft brush or a medical bulb with warm water. Do not use wire without insulation to avoid damaging the tube.
