Why the Daewoo refrigerator does not freeze: a complete analysis of the reasons and solutions

Have you opened the refrigerator Daewooand there, instead of the usual cold, it’s warm, and the food starts to spoil? Don’t rush to call a specialist: in 60% of cases the problem can be fixed on your own. This article will help you figure out why your refrigerator has stopped freezing, even if it appears to be working (the light is on, the noise of the compressor is heard). We will consider both obvious reasons (for example incorrect temperature settings), and hidden faults (from freon leaks to thermostat breakdown).

A feature of refrigerators Daewoo (series FR, RN, FRS) is sensitivity to voltage changes and a tendency to clog the capillary tube if used incorrectly. If your model is with a system No Frost, the reasons may differ from units with drip defrosting. In the article you will find:

• 🔍 Diagnostics by symptoms (the refrigerator is not freezing, but the light is on / the compressor is running non-stop / the freezer is working, but the refrigerator compartment is not).
• 🛠️ Step-by-step instructions for do-it-yourself repairs (with photos and error codes for popular models).
• ⚠️ Warningswhen independent repair is dangerous and it is better to call a specialist.
• 💰 Repair cost in service centers (table by types of breakdowns).

1. Checking the obvious reasons: what to do first. turn

Before disassembling the refrigerator, rule out simple problems that do not require repair:

• 🔌 Power and socket: Make sure that the plug is tightly inserted into the socket. Try connecting the refrigerator to another outlet (sometimes the problem is in the circuit breaker on the panel). data-i="71">If the contact is weak, the compressor protection may be triggered. Daewoo FR-410 And RN-305 If the contact is weak, the compressor protection may be triggered.
• ❄️ Temperature settings: On the control panel (or inside the chamber), check whether the optimal values are incorrect: -18°C for the freezer and +4°C for the refrigerator. cameras. In models with touch control (Daewoo FRS-220), a failure may occur after a power outage.
• 🚪 Door closure tightness: See if a foreign object is interfering with the seal (for example, a bag of food): if it pulls out easily when the door is closed, the seal is worn out.

If the refrigerator Daewoo is equipped with a display, pay attention to error codes:

• E1 - problem with the refrigerator compartment temperature sensor.
• E2 - sensor malfunction freezers.
• E4 —fan failure (relevant for models with No Frost).

Attention! If the refrigerator Daewoo immediately displays an error E5 or E6after being connected to the network, this may indicate short circuit in the compressor circuit -further operation is dangerous!

2. The refrigerator works, but does not freeze: compressor diagnostics

If the compressor is humming, but there is no cold, the problem may lie in:

• 🔧 Malfunctions of the starting relay (a common problem in models Daewoo RN-380 over 5 years). The relay may click, but not start the engine.
• 🧊 Leakage freon: if the tubes on the rear wall do not heat up and the compressor runs without stopping, the system is most likely depressurized.
• 🌡️ Failure of the thermostat: in mechanical models (Daewoo FR-201) this is a common reason for the lack of cold.

How to check the compressor:

1. Unplug the refrigerator and wait 10 minutes.
2. Remove the back cover (in most models it is secured with 4-6 screws).
3. Start the refrigerator and touch the tubes:
   • 🔥 Hot tube (condenser outlet) - the compressor is running.
   • ❄️ Cold tube (return line) - freon is circulating.
   • 🚫 Both tubes are at room temperature - no refrigerant or the capillary system is clogged.

In models Daewoo with an inverter compressor (FRS-U series), the diagnosis becomes more complicated - you will need a multimeter to check if the winding resistance is different from the norm. (usually 20-40 Ohm), the compressor must be replaced.

3. Problems with the No Frost system: why the upper chamber does not freeze

Refrigerators Daewoo with a system No Frost (for example, FRS-260, FRS-390) often suffer from:

• 🌀 Fan freezing: if the blades are covered with ice, cold air does not circulate Check whether the fan is spinning when the door is open (normally it should be). stop).
• 🔥 Burning of the defrosting heating element: if the ice in the freezer does not melt during automatic defrosting, the heating element is to blame.
• 📡 Faulty defrost sensor: in this case, the control board does not start the cycle defrosting.

How to defrost the No Frost system manually:

1. Unplug the refrigerator.
2. Remove all food from the freezer.
3. Leave door open for 12-24 hours (depending on the amount of ice).
4. After defrosting, wipe the drainage hole (located on the back wall of the freezer) with a cotton swab.

What will happen if you do not clean the drainage hole?

A clogged hole leads to the accumulation of water under the drawers for vegetables and the formation of an unpleasant odor. In advanced cases, water may leak onto the floor or freeze, blocking the operation of the fan.

If the problem persists after defrosting, check the defrosting heating element with a multimeter (the resistance should be 20-60 Ohm). In models Daewoo it is located behind the rear panel). freezers.

4. Freon leak: how to recognize and what to do

Refrigerant leak is one of the most serious failures:

• ⏳ The compressor works without stopping, but there is no cold.
• 🔊 The noise of the compressor has become louder than usual.
• 🧊 There is no condensation on the back wall of the refrigerator (normally it should be slightly damp).
• 💨 The condenser tubes (black grille at the back) do not heat up.

Causes of leakage:

• 🛠️ Mechanical damage pipes (for example, when moving the refrigerator).
• 🕳️ Corrosion aluminum tubes (a common problem in models older than 7 years).
• 🔧 Poor quality repair (if freon was previously charged).

It is impossible to eliminate the leak yourself - special equipment is required for evacuating the system and refilling with freon. Average repair cost:

In models Daewoo with isobutane (R600a), leakage is more dangerous than with freon R134a, since this refrigerant is flammable If you notice a specific smell (reminiscent of acetone), immediately turn off the refrigerator and ventilate the room!

5. Electronics malfunctions: control board and sensors

Modern refrigerators Daewoo (series FRS-U, FRN) are equipped with electronic control boards that can fail due to:

• ⚡ Voltage surges (even if mains power is used filter).
• 💧 Moisture ingress (for example, during defrosting).
• 🕰️ Natural wear (board service life is 7-10 years).

Signs of board malfunction:

• 📛 The display shows incorrect temperature or blinking.
• 🔄 The refrigerator turns on/off spontaneously.
• 🚫 Does not respond to button presses.
• 🔊 It beeps for no apparent reason.

To diagnose the board you will need multimeter Check:

1. Voltage at the board input (should be 220V).
2. Track resistance (infinite value indicates a break).
3. Presence of darkened or swollen elements (capacitors, resistors).

If the refrigerator Daewoo is equipped with a display, try resetting the settings to factory settings. this:

1. Disconnect the refrigerator from the network for 1 minute.
2. Hold the buttons Mode and Temp (or Freezer and Fridge, depending on the model) 10 seconds.
3. After the sound signal, release the buttons - the settings will be reset.

6. Clogged capillary tube: how to clean the system

The capillary tube is a thin channel through which freon enters the evaporator. Daewoo it often gets clogged due to:

• 🛢️ Poor quality of oil in the compressor (deposits form).
• 💧 Moisture ingress into the system (leads to the formation of ice plugs).
• 🔧 Incorrect freon filling (if the system was previously repaired).

Signs of blockage:

• 🕒 The compressor works for a long time, but there is little cold.
• 🔥 Condenser (rear grate) heats up unevenly.
• ❄️ The evaporator is only partially covered with frost.

Cleaning the capillary tube requires special equipment (hydraulic press or pneumatic gunYou can only try it yourself purge the system with nitrogen, but this is a temporary solution. Algorithm of actions:

1. Turn off the refrigerator and drain the freon (a manifold and refrigerant cylinder).
2. Disconnect the capillary tube from the filter-drier.
3. Connect a nitrogen cylinder and blow out the system under pressure 15-20 atm.
4. Install a new filter-drier and fill with freon.

Attention! If after cleaning the problem repeats, most likely there are metal particles or moisture left in the system - a complete flushing or replacement of the capillary tube will be required.

7 When to call a technician: 5 signs of a serious breakdown

Not all faults can be eliminated yourself. Contact the service center if:

• 🔥 The compressor does not startbut you can hear relay clicks (possible inter-turn breakdown of the windings).
• 💨 The refrigerator blows warm air, but the freezer is working normally (switching valve malfunction in two-compressor models).
• 🔋 The display shows an error E7 or E8 (problems with the control board or sensors).
• 🧊 The back wall of the refrigerator is covered with ice (leakage freon in the foamed part of the case).
• ⚡ The refrigerator is electrocuted (a breakdown on the body is a dangerous malfunction!).

Average cost of a technician’s visit in Moscow and the region — RUB 1,500–2,500. (includes diagnostics). Prices may vary in regions. When calling, please specify:

• Refrigerator model (Daewoo FR-..., RN-... etc.).
• Symptoms of breakdown (what exactly does not work).
• Year of purchase (for models older than 10 years, repair may not be practical).

8. Prevention: how to extend the life of a Daewoo refrigerator

To avoid breakdowns, follow the recommendations:

• 🔌 Use a voltage stabilizer (refrigerators Daewoo are sensitive to network fluctuations).
• ❄️ Defreeze the refrigerator at least once every 6 months (even if it has No Frost).
• 🧹 Clean condenser (rear grill) from dust 2 times a year.
• 🚪 Do not overload the door (in models Daewoo FR-... the hinges sag over time).
• 💧 Do not place hot products into the refrigerator (this increases the load on the compressor).

For models with No Frost especially important:

• 🌀 Do not block the ventilation holes products.
• 🧊 Do not accumulate ice in freezer thicker 5 mm.
• 🔧 Check the drainage hole for blockages.

If your refrigerator Daewoo has served for more than 10 years, pay attention to:

• 🔋 Wear of the compressor (increased operating time, loud noise).
• 🧲 Loss of the magnetic properties of the seal (the door does not close tightly).
• 🌡️ Failure of the thermostat (incorrect display temperature).

Attention! In refrigerators Daewoo manufactured before 2015, refrigerant R134ais often used, which is gradually replaced by more environmentally friendly R600awhen refilling. check with the specialist which freon is suitable for your model!

FAQ: Frequently asked questions about Daewoo refrigerators

The freezer works, but the refrigerator compartment does not. What is the reason?

In two-chamber ones. refrigerators Daewoo this may be caused by:

• Malfunction switching valve (in single-compressor models).
• Clogged capillary tube in the area responsible for the refrigeration chamber.
• Breakage fan (in systems No Frost).
• Leakage of freon from evaporator of the fridge compartment.

For diagnostics, turn off the refrigerator for 12 hours. If, after turning on, the fridge compartment started working, but then stopped freezing again, the problem is in valve or temperature sensor.

The Daewoo refrigerator constantly works and does not turn off. What should I do?

Continuous operation of the compressor may be due to:

• Freon leak (the compressor is trying to compensate for the lack of refrigerant).
• Thermostat malfunction (does not signal to shut down).
• Condenser contamination (poor heat transfer makes the compressor work longer).
• High room temperature (if the refrigerator is located next to the stove or radiator).

Try:

1. Clean the rear grill from dust.
2. Move the refrigerator to a cooler place.
3. Check the door seal (if it is damaged, the compressor runs without stopping).

If the problem persists, call a technician to check thermostat or leaks freon.

After defrosting, the Daewoo refrigerator does not turn on. What's the matter?

Possible reasons:

• The compressor protection has worked (wait 1-2 hours and try to turn it on again).
• Moisture has entered the control board (especially if defrosting was “hot” - with a hairdryer or boiling water).
• The fuse has blown in the power circuit (check the plug and socket).
• The drainage has frozen hose (in models with a drip system).

If the refrigerator does not turn on even after drying, check:

1. The voltage in the socket (should be 220V).
2. The integrity of the power cord.
3. The fuse on the compressor (in some models it is located in a separate block).

Is it possible to fill a Daewoo refrigerator with freon yourself?

Theoretically yes, but in practice it is dangerous and fraught with consequences:

• 🔥 Risk of explosion when working with a freon cylinder (especially R600a it flammable!).
• 💨 Incorrect dosage will lead to repeated failure.
• 🧊 Hit moisture into the system will accelerate corrosion of the tubes.
• 🔧 Violation of tightness when soldering tubes.

For refueling you need:

• Vacuum pump.
• Manifold with pressure gauges.
• Cylinder with freon (the exact type of refrigerant is indicated on the nameplate of the refrigerator).
• Experience in soldering copper pipes.

If you are not confident in your skills, it is better to contact a specialist. The cost of refilling at the service is from 3,000 rubles., which is cheaper than that. repair after an unsuccessful independent attempt.

How much does it cost to repair a Daewoo refrigerator in the service?

Prices depend on the type of breakdown and region. Average prices for Moscow (2026):

Type of repair	Cost (rub.)
Replacement of the thermostat	2 500 — 4 000
Repair of the control board	3 000 — 7 000
Replacement of the compressor	8 000 — 15 000
Elimination of freon leakage + refilling	5 000 — 10 000
Replacing the No Frost fan	2 000 — 3 500
Cleaning the capillary system	4 000 — 6 000

The price does not include the price of spare parts. For example, a new compressor for Daewoo FR-... will cost 6,000–9,000 rubles., and the control board will cost. in 5,000–8,000 rubles.

Advice: Before repairs, ask the technician to tell you the exact cause of the breakdown and the cost of the work. If the refrigerator is more than 10 years old, sometimes it is more profitable to buy a new one.
