Modern models of refrigeration equipment from the South Korean giant Samsung are famous for their reliability and advanced system No Frostwhich relieves the owner of the need for regular manual defrosting. However, even the most advanced equipment requires periodic maintenance to maintain factory efficiency and hygiene. Many users mistakenly believe that the absence of ice inside the chambers means that the unit is completely autonomous, forgetting about hidden components where dirt accumulates.
If you notice a foreign smell, a decrease in the quality of freezing, or the appearance of moisture at the bottom of the refrigerator compartment, this is a sure signal that it is time for general cleaning. Unlike older models, cleaning Samsung No Frost refrigerator has its own technical nuances associated with the peculiarities of air circulation and a complex condensate removal system. Ignoring these procedures can lead to failure of expensive components.
In this material we will analyze in detail the algorithm of actions that will allow you to safely and effectively put your unit in order. You will learn how to get to hard-to-reach places, what is the best way to remove dirt, and what tools are really necessary for a quality result. Proper care will extend the life of the equipment and ensure the freshness of your products.
Preparation of equipment and necessary tools
Before taking active steps, it is necessary to properly prepare the workspace and tools. Chaotic cleaning without prior planning can take twice as long and not give the desired result. The first step is always to completely disconnect the device from the electrical network, since working with electrical appliances in damp conditions carries risks.
You will need to collect a certain set of tools that will help remove contaminants of varying degrees of complexity. You should not use aggressive household chemicals with chlorine or abrasive particles, as they can damage plastic and rubber seals.
For high-quality cleaning, prepare the following arsenal:
- 🧽 Soft sponges and microfiber cloths for wiping surfaces without scratches.
- 🧴 A specialized refrigerator cleaner or a weak solution of baking soda.
- 💧 A spray bottle with warm water for rinsing and applying the cleaning composition.
- 🧹 A bottle brush or a long flexible brush for cleaning the drainage holes.
It is also important to empty the refrigerator compartments of all products. If you are planning a deep cleaning with defrosting the evaporator, it is better to transfer the products into bowls with ice or into another working refrigerator to avoid spoilage of stocks.
Dismantling and washing of internal elements
The system No Frost implies the presence of many removable shelves, drawers and partitions that are easily removed for washing. Models Samsung often use glass shelves with plastic edging and transparent plastic containers for vegetables. All these elements must be removed from the case.
It is better to wash removable parts in the bathroom or under the shower using warm water. Cold water should not be used, as a sudden change in temperature can lead to cracking of tempered glass or deformation of plastic. After washing, the parts must be completely dry before reinstalling them.
⚠️ Attention: Never wash glass shelves with hot water immediately after removing them from the freezer. Thermal shock is guaranteed to lead to the appearance of cracks.
The internal walls of the chamber also need to be treated. Pay special attention to corners and joints where food debris may accumulate. To remove stubborn stains, you can use a toothbrush with soft bristles.
Here is a table of recommended products for various types of stains:
| Type of contamination | Recommended product | Tool |
|---|---|---|
| Grease stains | Solution of laundry soap | Sponge |
| Dried drops | Warm water with soda | Napkin microfiber |
| Mold in the corners | Vinegar solution (1:3) | Toothbrush |
| Scale on parts | Citric acid | Soft brush |
After treating all surfaces, they must be thoroughly wiped with a dry cloth. Remaining moisture can cause the formation of new ice or an unpleasant odor.
Cleaning the condensate drainage system
One of the most common reasons for the appearance of a puddle at the bottom of the refrigerator compartment is a clogged drainage channel. In the system No Frost moisture formed on the evaporator must flow freely into a special tray located above the compressor. If this path is blocked by crumbs or mold, water begins to accumulate inside.
You can usually find the drainage hole on the back wall of the refrigerator, below, under the lower shelves. It is a small round hole. To clean it, you can use a special flexible brush, which is often included, or a cotton swab twisted into a rope.
Carefully insert the tool into the hole and make rotational movements, trying to push the clog deeper or remove it out. After mechanical cleaning, it is recommended to pour a little warm water into the hole to check the patency of the canal. If the water drains quickly and with a characteristic gurgle, then the problem is solved.
⚠️ Attention: Do not use sharp metal objects (knitting needles, wire) to clean the drainage. You can damage the thin walls of the plastic channel or pierce the thermal insulation layer.
Regular maintenance of this unit will save you from the need to move a heavy unit and disassemble the back panel.
Maintenance of the evaporator and fan area
Get to the evaporator in refrigerators Samsung with the system No Frost it is more difficult, since it is hidden behind a plastic panel on the back wall of the freezer. However, this is where ice coats most often form if the defrost system is not working correctly or the drainage is clogged.
To access the evaporator, you usually need to remove several screws and carefully unclip the plastic panel clips. This must be done with caution, as plastic becomes brittle in the cold and can crack. Before removing the panel, it is recommended to let the refrigerator stand unplugged for several hours so that the ice thaws a little.
Once you open access, you will see a ribbed evaporator radiator and a fan. If there is ice on the radiator, it must be carefully removed. Do not pick the ice with a knife - there is a high risk of damaging the refrigerant tubes, which will lead to freon leakage and expensive repairs.
What to do if the evaporator is covered with a thick layer of ice?
If you see that the evaporator is completely clogged with ice, this may indicate a malfunction of the defrost heating element or sensor defrost or timer. In this case, simple cleaning will only give a temporary effect, and after a couple of days the problem will return. Diagnostics with a multimeter is required.
After removing ice and dirt, wipe the insides of the camera with a dry cloth. Make sure that the fan blades rotate freely and do not touch the ice crust.

Care for rubber seals and outer casing
Rubber seal around the perimeter doors are a key element that ensures the tightness of the chamber. If the rubber is contaminated with grease or food debris, it begins to leak warm air, which causes the compressor to wear out. In addition, black mold often grows in the folds of rubber.
Wipe the seal with a soft sponge soaked in a soapy solution or a special product for rubber. Pay special attention to the inner corner of the joint where the rubber meets the body. For hard-to-reach places it is convenient to use a cotton swab.
The outer casing of refrigerators Samsung often has a coating Anti-Fingerprint (fingerprint protection). Do not use abrasive powders, hard brushes or solvents to clean it. It is enough to wipe the surface with damp microfiber and polish with a dry cloth.
If persistent dirt appears on the body, you can use specialized sprays for stainless steel. Movements should be directed along the texture of the metal (if there is one) or vertically/horizontally so as not to leave streaks.
Completing the process and checking the work
After all the elements are washed, dried and installed in their places, you can proceed to the final stage. Make sure all shelves and drawers fit tightly and completely. The doors should close with a characteristic clap, and the seal should fit tightly around the entire perimeter.
Plug in the refrigerator. During the first hours of operation, it may work more noisily or intensively, reaching the set temperature. This is normal. Do not load products into empty chambers immediately - let the unit run idle for at least 30-40 minutes.
Check whether water appears under the refrigerator or at the bottom of the chambers after several hours of operation. If everything is dry and the temperature is normal, the procedure can be considered successfully completed.
Frequently asked questions (FAQ)
How often do you need to completely defrost and clean a Samsung No Frost refrigerator?
Despite the name of the system, it is recommended to carry out complete defrosting and general cleaning at least once a year. This is necessary for hygiene and checking the condition of hidden components.
Can a steam cleaner be used to clean a refrigerator?
A steam cleaner can only be used for external surfaces and removable shelves. Directing hot steam at the internal walls, seals and especially at the evaporator area is strictly prohibited due to the risk of damage to plastic and electronics.
How to remove odor from the refrigerator after cleaning?
Natural absorbents help best: activated carbon, soda in an open can or special odor absorbers. Ventilating the chambers for several hours is also effective.
Why does the refrigerator not turn off for a long time after cleaning?
After washing, the walls and food (if they are already loaded) are warm, and there is a lot of humid air inside. The compressor works in increased mode to cool the volume and evaporate excess moisture. This is normal and will go away in a few hours.
