Refrigerators Samsung with the system No Frost equipped with a damper - a small but critical element that regulates the flow of cold air between the freezer and refrigerator compartments. If your unit has stopped cooling, ice has appeared on the back wall, or the compressor is running non-stop, the problem may lie in the damper. However, finding it is not so easy: depending on the model, it can be located in different places, and access to it is often blocked by panels or other parts.
In this article we will look at where exactly to look for the damper popular series of refrigerators Samsung (including RB, RT, RS i RF), what it looks like in the photo, and what signs indicate its breakdown. You will also find out whether you can repair or replace the damper yourself, and when you should contact a specialist. For clarity, we present diagrams of the internal structure and a table of compatibility of parts.
What is a damper in the refrigerator and why is it needed
The damper (or air damper) is a movable plate that opens and closes the channel between freezer and refrigerator compartments. Its operation is controlled electronic module based on the readings of temperature sensors. When the refrigerator compartment warms up, the damper opens, allowing cold air from the freezer to enter. As soon as the temperature reaches the set value, it closes.
In models Samsung s Full No Frost the damper performs another function: it prevents freezing of the evaporator. If it gets stuck in the open position, the refrigerator compartment will become overcooled, and the freezer, on the contrary, will not freeze well. When jammed in the closed position, the refrigeration compartment will stop cooling at all.
- 🔹 The main tasks of the damper:
- ❄️ Adjusting the temperature in the refrigeration chamber
- 🌀 Preventing ice formation on the evaporator
- ⚖️ Balancing the load on the compressor
- 📉 Saving energy by optimizing the operation of the system
In most refrigerators Samsung the damper is a plastic part with an electric drive (motor) and a lever. In some models, it is equipped with a heating element to prevent icing. In refrigerators of the RF series (with a French door), the damper is often duplicated - one controls the flow into the refrigerator compartment, the second controls the flow into the freshness zone (if there is one).
Where is the damper located in a Samsung refrigerator: search by models
The location of the damper depends on refrigerator designs the defrosting system. In most cases, it is hidden behind the rear panel of the refrigerator, but in some models it may be in the freezer compartment or behind a decorative cover at the top. Below are typical layout diagrams for different series.
First, determine which series your refrigerator belongs to. The serial number is located on a sticker inside the camera (usually on the left side of the camera) or on the back of the case. The first two letters after the word Model indicate the series:
- 📌 RB - classic two-chamber refrigerators
- 📌 RT - models with a top freezer
- 📌 RS — Side-by-Side (doors next to each other)
- 📌 RF - refrigerators with a French door
| Refrigerator series | Typical location of the damper | Access features |
|---|---|---|
| RB (for example, RB30J3000WW) | Behind the rear panel of the refrigerator compartment, in the upper part | It is necessary to remove the plastic cover and disconnect the temperature sensor |
| RT (for example, RT28K5030SL) | In the freezer compartment, behind the evaporator | You need to dismantle the back panel of the freezer and remove the fan |
| RS (for example, RS552NRUA1) | In the upper part refrigerator compartment, behind the decorative panel | Access is possible without complete disassembly, but care is required |
| RF (for example, RF23HCEDBSR) | Two dampers: one in the refrigerator compartment, the second in the freshness zone | Difficult access, often requires removal shelves |
If your model is not listed in the table, use the universal search method:
- Disconnect the refrigerator from the mains.
- Remove all products and shelves from the refrigerator compartment.
- Remove the back plastic panel (it is secured with latches or screws).
- Look for a plastic part with a motor and a lever - this is the damper.
What the damper looks like: photos and diagrams
The damper in refrigerators Samsung usually a plastic box with a movable cover, a drive (motor) and wires. In some models, it can be equipped with a heating element (to prevent icing) or additional sensors. Below is a description of the appearance for different types:
- 📸 Classic damper (series RB, RT): White or gray plastic case measuring approximately 10x15 cm, with a lever and a motor. Often marked. data-i="114">or similar.
DA61-01232Aor similar. - 📸 Damper for Side-by-Side (RS): More compact, can be integrated into the air duct, sometimes covered with thermal insulation.
- 📸 Double damper. (RF): Two separate parts - one for the refrigerator compartment, the second for the freshness zone. May differ in size.
The diagram below shows a typical location of the damper in the model Samsung RB30J3000WW:
Data arrangement of the damper in the RB30J3000WW
The damper is marked with a red circle. It is located behind the rear panel of the refrigerator, next to the fan. Two wires (power and signal from the control module) and a lever connected to the motor are connected to it. In some modifications, a temperature sensor and a heating element are located nearby (yellow rectangle in the diagram).
If you are not sure that you have found the damper, pay attention to the following. signs:
- ✅ The presence of a movable plate that can be opened/closed manually.
- ✅ Connection to wires (usually 2-4 pieces).
- ✅ Inscriptions on the body (for example,
DAMPERorAIR DOOR). - ✅ There is a fan or air duct nearby.
Signs of a faulty damper: when you need it. check
The damper is a moving mechanism that wears out over time. The main reasons for its failure are:
- 🔧 Mechanical wear (cracks in the plastic, breakage of the lever).
- ❄️ Icing due to a malfunction of the heating element. element.
- ⚡ Electrical problems (motor burnt out, contacts oxidized).
- 📱 Failure in the module control (incorrect opening/closing signals).
The following symptoms indicate that the damper has failed:
| Symptom | Probable cause | What to do |
|---|---|---|
| The refrigerator compartment does not cool, the freezer is working normal | The valve is stuck in the closed position | Check the mechanism for icing or broken lever |
| The refrigerator compartment is too cold (food is freezing) | The damper is stuck in the open position | Try to close it manually or replace the motor |
| Continuous operation of the compressor without shutdowns | The temperature sensor does not receive a signal to close the damper | Check the wires and contacts, test the sensor |
| Ice on the back wall of the refrigerator compartment | Icing of the damper or air duct | Defrost the refrigerator, check the heating element |
If you observe one or more of these signs, try defrost the refrigerator for 12-24 hours. Sometimes this helps remove icing and restore the damper's operation. If the problem remains, diagnostics will be required.
How to check the damper yourself: step-by-step instructions
Before replacing the damper, make sure that it is the problem. To do this, follow these steps:
Disconnect the refrigerator from the mains
Remove the back panel of the refrigerator compartment
Find the damper and visually inspect for damage
Try to open/close it manually (it should move easily)
Check the wires and contacts for oxidation
Connect the refrigerator and listen to whether the motor is running (should make a slight noise when opening)
Check the voltage at the damper contacts (should be 5-12 V when opening)-->
For For more in-depth diagnostics, you will need a multimeter. Follow the instructions:
- Unplug the refrigerator.
- Remove the back panel of the refrigerator compartment (usually it is secured with latches or screws).
- Find the damper and disconnect the connector with wires from it.
- Translate multimeter in resistance test mode (ohmmeter) and connect the probes to the contacts of the damper motor. Resistance should be within
200–500 Ohm. If the device shows0(short circuit) or∞(open circuit), the motor is faulty. - Connect the refrigerator to the network and use a tester to check the voltage at the damper contacts at the moment when it should open (for example, when the temperature in the chamber increases). The voltage should be
5–12 V.
If the motor is working, but the damper does not move, the problem may be:
- 🔌 Oxidized contacts (clean them with alcohol).
- 🧊 Icing of the mechanism (defrost the refrigerator).
- 📱 Faulty control module (board diagnostics required).
How to replace the damper in a Samsung refrigerator: a detailed guide

Where to buy spare parts for Samsung?
Original dampers can be ordered at Samsung service centers or on specialized websites (for example, Samsung Parts, eBay, AliExpress). When purchasing, check the exact model of your refrigerator - dampers from different series are not interchangeable!
The cost of a new damper varies from 1,500 to 4,000 rubles depending on the model. If you are not confident in your abilities, it is better to contact a service center - errors during replacement can lead to damage to other components.
Common mistakes when repairing the damper and how to avoid them
Even experienced craftsmen sometimes make mistakes when working with the damper. Here are the most common of them and ways to prevent them:
- ❌ Ignoring defrosting before repair.
➡️ Always defrost the refrigerator at least
12 hours- this will eliminate ice that may interfere with diagnostics. - ❌ Use of force when opening the damper.
➡️ If it does not move, do not try to break it - first check if ice or a foreign object is blocking it.
- ❌ Replacing only the motor instead of the whole dampers.
➡️ In most cases, the motor is sold separately, but if the housing or lever is damaged, a complete replacement will be required.
- ❌ Wrong connection of the wires.
➡️ Before disconnecting, take a photo of the connection diagram or mark wires.
Another typical problem is when dismantling the panel. Be careful: the plastic in refrigerators damage to the air duct when dismantling the panel. Be careful: plastic in refrigerators Samsung is quite fragile, especially in older models. If you accidentally break the fastener, it can be restored using epoxy glue (but this is a temporary solution - it is better to replace the part).
When to contact a technician: complex cases
Not all shutter breakdowns can be repaired yourself. Contact the service center if:
- 🔧 The damper is working, but the refrigerator still does not freeze (there may be a problem with the compressor or freon).
- ⚡ After replacing the damper, errors appeared on the display (for example,
E1,E2). - 📱 The control module is faulty (reflashing or replacement of the board is required).
- 🔥 The damper sparks or smells of burning (possibly a short circuit in the motor).
The cost of repairs in the service depends on the nature of the breakdown:
| Type of work | Cost (RUB) |
|---|---|
| Diagnostics | 500–1 500 |
| Replacement of the damper (with spare parts) | 3 000–6 000 |
| Replacement of the damper motor | 2 000–4 000 |
| Repair of the control module | 4 000–10 000 |
Before the technician's visit:
- Defrost the refrigerator.
- Prepare access to the back panel (by removing food and shelves).
- Write down the refrigerator model and serial number.
FAQ: Answers to frequently asked questions
Is it possible to operate a refrigerator with a faulty damper?
Technically yes, but this will lead to increased wear on the compressor, increased energy consumption and uneven cooling of food. The temperature in the freezer may rise, and in the refrigerator it may fall below normal (the food will freeze). cool or ice appears on the back wall, defrost and inspect the damper for icing. On average, it is enough to do this once every 6-12 months
How often should the damper be cleaned?
Under normal conditions, the damper does not require regular cleaning. However, if you notice that the refrigerator has become worse in cooling or ice has appeared on the back wall, defrost and inspect the damper for icing. On average it is enough to do this Once every 6–12 months.
Why does the damper open and close too often?
This may be due to:
- Faulty temperature sensor (it gives false signals to the control module).
- Problem in the control module (board diagnostics required).
- Violation of the chamber seal (check the rubber seal on the door).
If frequent operation is accompanied by increased noise, the damper motor may be worn out.
Is it possible to repair the damper or just replace it?
In most cases, the damper is replaced entirely, since its body and mechanism are non-separable, however, if the problem is only in the motor or wires, they can be replaced separately. For example, the damper motor for the damper. model Samsung RB30J3000WW costs about 1,200 rubles, and a complete damper costs 2,500 rubles. It is more profitable to repair if only one element is damaged.
