Modern refrigerators Samsung with the system No Frost are reliable units, but even they sometimes require technical intervention. Most often, the need to remove the back wall of the freezer occurs when the condensate drainage system becomes clogged with ice and moisture begins to accumulate at the bottom or, even worse, leak onto the floor. Also, dismantling may be required to replace Evaporator heating element or check the fan.
Many owners are afraid to start disassembling for fear of damaging the fragile plastic or breaking the tightness of the circuit. However, in the models Samsung the design is designed to provide access to the main components without completely disassembling the case. The main thing is to act consistently, not to use excessive force and to know where the hidden fasteners are located.
Before starting work, make sure that you have accurately determined the cause of the malfunction. Often the problem lies precisely in the freezing of the evaporator behind the rear panel. Defrosting in such cases it gives only a temporary effect, and a full repair requires access to the heating element and drainage hole. In this article, we will analyze the dismantling process in detail so that you can do the job efficiently.
Preparation of the workplace and the necessary tools
Any repair of household appliances begins with ensuring safety. The first and most important step is to unplug the refrigerator from the power supply. Remove the plug from the socket and make sure that access to it is not blocked by anything, so as not to accidentally turn on the device during operation. It is also recommended to empty the freezer compartment of food so that it does not interfere with access to the back wall.
For dismantling you will need a minimum set of tools. In most cases, a Phillips screwdriver is sufficient, but in some models there may be screws with slots like Torx (asterisk). Prepare a container for water, as melted ice may leak when removing the panel, and a towel for wiping the surfaces.
- 🛠️ Phillips screwdriver (sizes PH1 or PH2)
- 🔧 Slotted screwdriver for carefully prying up the latches
- 🧣 Towel or rag to collect moisture
- 🧊 Plastic spatula (optional, for removing ice)
It is important to ensure good lighting of the work area. The inside of the freezer is dark and small fittings may not be visible in dim light. Use a flashlight or portable lamp to clearly see where the screws and plastic latches are attached. Warning: Never try to pry out a plastic panel with a knife or metal object. Plastic becomes brittle in the cold, and the risk of breaking the fastening or breaking through the wall is very high. plastic latches.

Design features and types of Samsung fastenings
The back wall in refrigerators Samsung with the system No Frost performs the function of an air duct. Behind it lies the evaporator, fan and defrost system. The panel can be made of expanded polystyrene or more rigid plastic, depending on the series of the refrigerator. Fastenings are usually combined: screws plus hidden latches.
In older models, the screws are often located openly, while in new series, such as RB30 or RB37, manufacturers hide the fasteners under decorative plugs or design elements. This is done to improve aesthetics, but complicates initial access. Carefully inspect the surface of the panel in good lighting.
| Type of fastening | Location | Tool | Risk of damage |
|---|---|---|---|
| Slotted screws | Po panel perimeter | Phillips screwdriver | Low |
| Hidden screws | Under plugs or in niches | Thin screwdriver | Medium |
| Plastic clips | At the ends and in the center | Plastic spatula | High |
| Guide grooves | Top and bottom edge | Absent (manual) | Middle |
Particular attention should be paid to models with a display on the door, since wiring harnesses can pass in close proximity to the rear wall mounting area inside the camera. Although the wiring usually goes through the door hinge, extra caution when working with electrical components electrical components
Step-by-step instructions for removing the panel in the freezer
The dismantling process begins with searching for all visible screws. Carefully inspect the top, bottom and sides of the back wall. If the screws are covered with decorative round caps, carefully pry them off with the tip of a slotted screwdriver. Do not use excessive force so as not to crumble the plastic.
After unscrewing all the screws, the panel will not fall on its own. It is held on by plastic latches around the perimeter. Start releasing the fasteners from one of the bottom corners. Gently pull the panel towards you while rocking it slightly. You should hear a characteristic click of the clip being released.
☑️ Algorithm for removing the back wall
Move along the perimeter, gradually freeing the wall. Do not pull sharply as there may be temperature sensors or backlight wires attached to the panel. If the panel does not budge, check whether the screw in the upper part or in the area where the shelves are attached is not unscrewed.
⚠️ Attention: If the panel is frozen to the ice, do not use force. Let the ice melt naturally or use a hairdryer at the minimum temperature, directing warm air to the joints, but not to the plastic itself, so as not to deform it.
Access to the evaporator and defrosting system
After successfully removing the back wall, your view will be revealed aluminum evaporatorcovered with thin tubes, and a fan that circulates cold air. This is where a “coat” of ice most often forms, which blocks the channels and interferes with the normal operation of the refrigerator. At the bottom you will see a drainage hole, which could also be clogged.
For proper maintenance, you need to defrost the evaporator. If the ice layer is thick, you can carefully remove the main pieces with your hands (wearing gloves), but it is better to melt the main mass. To do this, you can use warm water poured into the pan under the evaporator, or leave the refrigerator open for several hours.
It is critical to check the condition of Defrosting heating element (the heater), which is usually located at the bottom of the evaporator or built into the drainage trench. It is responsible for melting the ice automatically. If the heating element is burnt out, ice will build up again and again, causing the problem to recur in a couple of weeks.
Also inspect the drainage hole. It should be free. If food crumbs or pieces of ice are stuck there, clear the channel with a soft wire or brush. Pour some warm water there to make sure that it flows freely into the pan under the compressor.
Nuances of dismantling in Side-by-Side refrigerators
In refrigerators Samsung Side-by-Side type, the design may differ. Here the back wall of the freezer is often divided into sections or has a more complex fastening system. In some models, to access the evaporator, you need to remove not only the plastic panel, but also metal protection or air ducts.
Pay attention to the presence of additional sensors. In large models there may be several of them: one controls the air temperature, another controls the evaporator temperature, the third can monitor the mode quick freeze. When removing the panel, make sure that you do not damage the thin wires going to these sensors.
If your refrigerator is equipped with a zone Flex Zone or other additional chambers, make sure that you are removing the freezer compartment panel. The design of the panels in different chambers may be identical, but the location of the fastening elements may be different.
- 🔍 Carefully examine the upper end of the panel for hidden screws.
- ❄️ In large chambers, ice can freeze into massive blocks, holding the panel.
- 🔌 Check the fan connectors before completely removing the wall.
In models with a dual cooling circuit (Twin Cooling System), additional tubes and dampers may run behind the rear wall. Be extremely careful not to bend the aluminum tubes, as this may lead to freon leakage.
Assembling and checking the functionality of the system
After you have carried out the necessary manipulations (cleaning, replacing the heating element or checking the fan), you can begin assembly. Place the back panel in place, starting with the top rails. Carefully press the panel along the perimeter until all latches click. Make sure there are no gaps anywhere.
Tighten all the screws, but do not overtighten them. The plastic should fit snugly, but excessive force may cause cracks around the mounting holes. If you removed the decorative plugs, install them back.
Plug in the refrigerator. In the first hours of operation, it can work more intensively, gaining temperature. Listen to the fan: it should hum smoothly, without any extraneous knocks or vibrations. If you have changed the heating element, during the first defrost cycle (usually after 8-12 hours of operation) you can check its heating.
⚠️ Attention: Do not load food into the freezer immediately after turning it on. Allow the refrigerator to run empty for 2-3 hours to stabilize the temperature and make sure there are no leaks.
Common mistakes during disassembly and how to avoid them
One of the most common mistakes is trying to remove the panel without unscrewing all the screws. In a hurry, craftsmen miss fasteners hidden under stickers or in deep niches, and then break the plastic by tugging at the wall. Always run your finger around the perimeter to check for screws.
Another mistake is using sharp metal objects to pry off the clips. This is almost guaranteed to lead to scratches and chips on the plastic. Use only plastic spatulas or old credit cards to pry the latches.
Ignoring the condition of the seals and insulation behind the panel is also a mistake. If you notice that the insulation (usually a white porous material) is loose or damaged, it needs to be repaired. Violation of thermal insulation will lead to the constant formation of condensation and ice.
Do not forget about safety precautions when working with electrical equipment. Even after disconnecting from the network, a charge may remain in the capacitors. Be careful when touching metal parts and electrical connectors.
Is it possible to remove the back wall without defrosting the refrigerator completely?
Technically, you can remove the panel if it is not frozen solid. However, if there is a lot of ice inside the chamber, it may crumble when the wall is removed, damaging the plastic elements or falling to the floor. In addition, without defrosting, you will not be able to properly clean the drainage and check the heating element. It is better to spend time on complete defrosting (at least 24 hours with the doors open).
What to do if the plastic latch on the wall breaks?
If one latch breaks, the panel can be fixed using a small amount of sealant or special glue for plastic, but only pointwise, so as not to disrupt the operation of the system. As a last resort, you can drill a neat hole and screw the panel with a self-tapping screw with a wide head, having previously selected the color. The main thing is to ensure a tight fit.
How often should you clean the drainage hole in Samsung No Frost?
It is recommended to carry out preventive cleaning of the drainage once every 1-2 years. However, if you notice that water has begun to accumulate at the bottom of the chamber or under the drawers, cleaning should be done immediately. The frequency depends on the humidity of the food you store and the frequency of opening the door.
Why did the refrigerator begin to make more noise after assembly?
An increase in noise may indicate that the back wall is out of place and is touching the fan blades. Noise can also occur due to resonance if the panel is not pressed tightly with the latches. Check if the fan rotates freely and if there is vibration of the plastic panel when the compressor is running.
