Samsung two-chamber refrigerator does not freeze: causes and step-by-step solution to the problem

If your two-chamber refrigerator Samsung stops freezing, but the freezer is working, and in the main compartment the temperature rises to room temperature, this is an alarming signal. Such a malfunction not only threatens food spoilage, but can also indicate serious problems in the cooling system. In most cases, the reasons lie in incorrect settings, clogging of the capillary tube or breakage of key components a compressor, thermostat or fan.

It is important to understand that two-chamber models Samsung (series RB, RT, RS etc.) have a common refrigerant circulation system, but separate control circuits for each chamber. If the freezer is functioning, but the refrigerator compartment is not, the problem is localized in the zone main chamber evaporator or related components. In this article we will analyze unique diagnostic features of specifically dual-chamber Samsung modelswhich are often overlooked even by experienced technicians.

1. Primary diagnostics: what to check first

Before disassembling the refrigerator or calling a technician, perform basic checks. About 30% of cases of “non-frosting” are associated with human factor - incorrect settings or external operating conditions.

• 🔌 Power and socket: Make sure that the refrigerator is connected to a working outlet. Try plugging in another device (for example, charging a phone) - if it does not work, the problem is electrical.
• ❄️ Cooling mode: On models with a display (Samsung RB37J5230SA, RS62R5001M9), check whether the mode Vacation (vacation) or Eco, which turn off the main chamber.
• 🌡️ Temperature settings: Optimal values for the refrigeration chamber - +3…+5°C. If the display shows -- or blinks, this may indicate a sensor failure.
• 🚪 Door closure tightness: Place a piece of paper between the seal and the housing - if it falls out, the seal is broken. On models with Twin Cooling Plus (double cooling system), even a small gap leads to freezing of the evaporator.

Pay special attention sound signals. If the refrigerator Samsung emit 3 short beeps is an error in the refrigerator compartment temperature sensor (DS or DS2 depending on the model). 1 long beep indicates problems with the fan. Error codes can be reset by holding the button Power Cool (or Fridge) for 10–15 seconds.

2. Typical reasons why the refrigerator compartment does not freeze

If the initial diagnostics did not reveal any problems, consider technical malfunctions. The table below shows the most common causes and their signs for two-chamber models Samsung.

Models with a system No Frost, where the fan is responsible for air circulation, are especially vulnerable. If it breaks, the cold from the freezer stops. enter the main chamber. In refrigerators with drip system (RT-series), freezing of the evaporator is more common due to a faulty defrosting thermostat.

⚠️ Attention: If your refrigerator Samsung manufactured before 2018 and equipped with refrigerant R-134a, if freon leaks, a complete recharge of the system is required. Modern models (R-600a) are less sensitive to microcracks, but also require professional repair.

3. Step-by-step instructions: what to do if the refrigerator does not freeze

If you decide to try to fix the problem yourself, follow this algorithm. Warning: working with freon, compressor and electrical circuits require special skills - if you do not have them, it is better to contact the service.

Check the voltage in the socket (should be 220–240 V)

Reset the settings to factory settings (button Power Cool + Fridge 10 sec)

Clean the condenser (rear grill) from dust

Test the thermostat with a multimeter (the resistance should change as it cools)

Check the operation of the fan (it should start when the freezer door is open)-->

Step 1: Defrosting and cleaning the system

Even if your model equipped No Frost, defrost the refrigerator for 12–24 hours. This will help:

• 🧊 Eliminate ice jams in the drainage system (relevant for RT-series).
• 🔄 Reset control board errors (often helps with failures after a power surge).
• 🔍 Detect freon leak (if after defrosting the refrigerator started working for a short time, but stopped freezing again).

Step 2: Checking the fan and evaporator

In models with No Frost (RB, RS series):

1. Disconnect the refrigerator from the mains.
2. Remove the back panel in the freezer (usually secured with 4-6 screws).
3. Check whether the fan rotates when turned on (you can gently turn the blades by hand - they should rotate freely).
4. Inspect the evaporator for the presence of ice. If it is covered with a thick layer, the problem is in the defrosting system (Defrost Heater or Defrost Sensor).

To check the defrost sensor, measure its resistance with a multimeter at room temperature - it should be within the limits 4–7 kOhm. If the readings are different, the sensor must be replaced.

Step 3: Diagnostics of the compressor and thermostat

The compressor in refrigerators Samsung is usually located in the lower part at the back. Signs of its malfunction:

• 🔊 The compressor does not turn on at all (no characteristic hum).
• 🔥 The compressor housing is excessively hot (more 80°C during operation).
• ⚡ The compressor turns on for 1-2 seconds and turns off (protection is triggered).

To check thermostat:

1. Locate the thermostat (usually located next to the light bulb or on the back wall of the refrigerator).
2. Remove the terminals and test the contacts with a multimeter in the mode 200 Ω.
3. At room temperature the resistance should be 0 Ohm (closed), when cooled (for example, with ice) - ∞ (open).

⚠️ Attention: On models Samsung with an inverter compressor (Digital Inverter), you cannot check the windings with a standard multimeter - this may damage the control board. Use only specialized testers for inverter motors.

4. When to call a technician: signs of serious breakdowns

Some faults cannot be eliminated without professional equipment and skills. Contact the service center if:

• 🛠️ Freon refilling required: A refrigerant leak can only be diagnosed using a leak detector. Self-refilling without evacuation of the system will lead to repeated breakdown.
• 🔧 The control board is faulty: If the refrigerator produces errors 5E, 8E or dE, flashing or replacing the module is required.
• ⚡ Problems with the inverter compressor: Repair of such compressors (Samsung Digital Inverter) requires original spare parts and calibration.
• 🧊 Evaporator freezing in No Frost: If ice forms after defrosting again within 24 hours, replacement is required Defrost Heater or Defrost Sensor.

The cost of repair depends on the type of breakdown:

5. Prevention: how to avoid breakdowns in the future

To extend the life of the refrigerator Samsung and avoid problems with cooling, follow these recommendations:

• 🧹 Cleaning the condenser: Vacuum the rear grille once every 6 months. On models No Frost the accumulation of dust increases the load on the compressor by 20–30%.
• 🚪 Sealant control: Once a month, wipe the rubber door seal with a weak solution of soda (1 tablespoon per 1 liter of water). This will prevent cracking and loss of tightness.
• ⚡ Voltage stabilizer: Refrigerators Samsung are sensitive to power surges. Use a stabilizer with a range 170–250 V.
• ❄️ Correct loading: Do not place products close to the back wall - this interferes with air circulation. In models with No Frost leave a gap of 3-5 cm.

For models with Twin Cooling Plus (dual cooling system) it is important:

• Do not store liquids in the refrigerator compartment in open containers - this leads to freezing of the evaporator.
• Once a year, carry out deep defrosting (even if the system is No Frost), turning off the refrigerator for 24 hours.

What happens if you ignore poor cooling?

If the refrigerator compartment is ineffective, but the freezer is working, this leads to:

1. Increasing the load on the compressor (reduces its life by 30–40%).

2. The formation of condensation on the back wall and rust of metal parts.

3. Reproduction of bacteria in products due to unstable temperature.

4. Breakdown of the control board due to constant Attempts of the compressor to “catch up” with cold.

6. Common mistakes during self-repair

Trying to save on calling a technician, many users make critical mistakes that aggravate the breakdown. Here's what cannot be done:

• 🔨 Clean the capillary tube yourself without experience: there is a risk of damaging it or introducing moisture into the system, which will lead to corrosion.
• ⚡ Connect the refrigerator to the network with the back panel removed: this can cause a short circuit or electric shock.
• 🧊 Use sharp objects to remove ice: even a small scratch on the evaporator will lead to freon leakage.
• 🔧 Replace the thermostat or sensors without checking: in 40% of cases the problem does not lie there, and in the control board.

It is especially dangerous to tamper with inverter compressors. For example, in models Samsung RB37J5230SA or RS62R5001M9 the compressor is controlled by a digital module, and its replacement requires calibration using service software (Samsung Smart Service Tool).

⚠️ Attention: If you find oil stains under the refrigerator, do not turn it on under any circumstances! This is a sign of freon leakage along with oil from the compressor. Operation in this mode will lead to jamming of the motor and complete replacement of the unit (cost - from 15,000 ₽).

7. Warranty repair: what you need to know

If yours. refrigerator Samsung is under warranty (usually 1-2 years for parts and labor, 5-10 years for the compressor), repairs should be free. However, there are nuances:

• 📄 Warranty card must be filled out without errors (serial number, date of purchase, store stamp).
• 🔧 Seals on the compressor must not be damaged - otherwise the warranty will be void.
• 🏠 DIY Repair (even replacing a light bulb) can serve as grounds for refusal.
• 📅 Terms: By law, repairs must be carried out within during 20 days (Article 20 of the Law "On Protection of Consumer Rights").

For models with Digital Inverter (Samsung RB30J3000WW, RS55N6751SL) the compressor warranty is often extended to 10 years, but only subject to annual service (cleaning, diagnostics). Check this in the product passport or on the website Samsung.

FAQ: Frequently asked questions about Samsung refrigerators

🔍 Why does the Samsung refrigerator beep and not freeze?

Three short signals indicate an error in the refrigerator compartment temperature sensor (DS). Four signals - a problem with the freezer sensor (DF). Try resetting the error by holding the button Power Cool 10 seconds. If the squeak is repeated, the sensor needs to be replaced.

❄️ Is it possible to defrost a Samsung refrigerator with No Frost?

Yes, despite the system No Frost, the manufacturer recommends defrosting the refrigerator once a year for 12-24 hours. This removes ice buildup on the evaporator, which is not visible to the user, but reduces cooling efficiency. After defrosting, wipe the seals and the back wall with a dry cloth.

🛠️ How much does it cost to replace a compressor in a Samsung refrigerator?

The cost depends on the model:

• Regular compressor: 8 000–12 000 ₽ (including work).
• Inverter compressor (Digital Inverter): 15 000–25 000 ₽ (calibration required).

On a model older than 7 years, replacing the compressor is often unprofitable - the cost can exceed 50% of the price of a new refrigerator.

📉 Why after defrosting Samsung refrigerator does not turn on?

Probable reasons:

1. It worked thermal protection of the compressor (wait 1-2 hours, then turn it on again).
2. Moisture got in on control board (requires drying with a hairdryer in the service).
3. Failed start-up protection relay (characteristic click when turned on, but the compressor does not start).

If the refrigerator does not turn on after 6 hours of drying, call a technician.

🔋 How to reset an error on a Samsung refrigerator?

Reset methods depending on the model:

• RB/RT series: Hold Power Cool + Fridge 10–15 seconds.
• RS series (Side-by-Side): Press Ice Type + Child Lock for 8 seconds.
• Family Hub: Log in in Settings → Diagnostics → Reset errors.

If the error appears again, write down its code and contact the service.
