The refrigerator does not freeze, but the light is on: 7 reasons and how to fix it yourself

Have you opened the refrigerator, but the food in the freezer has melted, although the light inside is on and the motor is humming? Or is there general silence - the compressor does not start, but the indicators work? This situation is familiar to many: a refrigerator stopped freezing, but outwardly it seems to be working. In 80% of cases, the problem can be fixed without calling a technician - just understand where to look for a breakdown.

In this article we will look all possible causeswhy the refrigerator does not freeze (or freezes weakly), but there is light inside. You will learn:

• 🔍 How to diagnose malfunction in 10 minutes - without tools.
• ⚙️ Step-by-step instructions repair the most common breakdowns (with photos and diagrams).
• 💰 When it is more profitable to call a technician, and when you can handle it yourself.
• ❄️ What to do with the productswhile the refrigerator is not working.

Do not rush to take the equipment to the service: in half the cases it is your fault clogged capillary tube, electronics failure or incorrect settings. And these problems are solved literally “on the knee”. Let's start with the simplest.

1. The first thing you need to check: 5 “quick” reasons

Before disassembling the refrigerator, rule out obvious problems that do not require repair. These items take no more than 5 minutes, but often save you from unnecessary expenses.

• 🔌 Power and socket. Make sure that the plug is firmly inserted into the socket (sometimes the contacts oxidize). Try connecting the refrigerator to a different outlet - perhaps the circuit breaker on the panel has triggered.
• ❄️ Defrost mode. In models with No Frost (for example, Samsung RL-34 or LG GA-B409) the settings sometimes get lost. Check if the mode Vacation or Demo is activated - they turn off cooling.
• 🌡️ Temperature sensor. If the display shows an error (for example, E1 at Indesit or H at Bosch), then the sensor is transmitting incorrect data. Try reset settings (instructions below).
• 🚪 Door seal. Press the piece of paper against the rubber gasket and close the door. If the sheet is easily pulled out, the seal is worn out and warm air penetrates inside.
• 🧊 Ice in the freezer. A thick layer of ice (more than 1 cm) blocks air circulation. In models with drip system (Atlant, Biryusa) this is a common cause of poor cooling.

If everything is in OK, but the refrigerator still does not freeze - proceed to in-depth diagnostics. Let's start with the compressor.

2. The compressor works, but does not freeze: what to do

If the motor is buzzing or clicking, but the refrigerator does not cool, the problem lies in one of three components: starting relay, capacitor or freon leak. Let's look at each case.

🔧 Starting relay: how to check and replace

The relay is the “starter” of the compressor. If it burns out, the motor will beep for 2-3 seconds and turn offor will not start at all. To check the relay:

1. Disconnect the refrigerator from the mains.
2. Remove the back cover (it is secured with 4-6 screws).
3. Find the compressor - it's black "barrel" with pipes. A relay is attached next to it (a plastic box with wires).
4. Carefully remove the relay and shake it. If something rattles inside, it is faulty.

Replacing the relay takes 10 minutes: buy an analogue (for example, for Atlanta it will be suitable for RBM-1, for Indesit — DANFOSS 103N0010-56), connect the wires in the same order and fasten it back.

⚡ Capacitor: signs of malfunction

The capacitor stores energy to start the compressor. If it is swollen or fluid leaks, it needs to be replaced. You can check the capacitor with a multimeter:

1. Switch the tester to resistance measurement mode (200 Ohms).
2. Touch the leads of the capacitor with the probes.
3. If the arrow does not move or shows "0" - the part is faulty.

The cost of a new capacitor is from 300 rubles. A universal one is suitable CBB61 (for most models Samsung, LG, Beko).

❄️ Freon leakage: how to determine

If the compressor works without stopping, but the refrigerator does not freeze, most likely a freon leak has occurred in the evaporator or circuit. Signs:

• 🔥 The condenser tube (grid at the back) does not heat up.
• 💧 There are puddles under the refrigerator (freon evaporates, but sometimes oil drips).
• ❄️ The freezer is covered with frost on only one side.

It is difficult to fill freon yourself - you need a special tool. But you can find the leakage using a soap solution:

1. Apply the solution to the tubes and connections.
2. Turn on the refrigerator. Bubbles will appear at the leak site.

⚠️ Attention: Freon R-600a (used in modern models) is flammable! Do not smoke or use open fire near the refrigerator when checking.

3. The refrigerator does not freeze, but the light is on: the electronics are to blame

If the compressor does not start at all, but the light inside is on, the problem is control board or thermostat. Let's look at both options.

📱 Control board failure

Modern refrigerators (Samsung RF23, LG InstaView) are equipped with electronic units that sometimes "glitch". Signs:

• 🔄 The display flashes or shows an error (Er IF, E5).
• 🔇 The compressor does not respond to temperature changes.
• 🔌 The refrigerator spontaneously turns off.

The first thing to do is reset the settings:

1. Unplug the refrigerator for 10 minutes.
2. Turn it back on and hold the button Super Freeze (or Power Cool) 15 seconds.
3. If the error remains, the board needs to be flashed (this is done in the service).

🌡️ Faulty thermostat

In older models (Biryusa-3, ZIL) and some new ones (Indesit C16) the thermostat is mechanical. If it breaks, the compressor will not receive a command to start. It's easy to check the thermostat:

1. Find the thermostat (usually inside the chamber, under the plastic cover).
2. Remove the wires from it and short them together (for a short time!).
3. If the compressor starts, the thermostat is faulty.

Replacing the thermostat will cost 500–1500 rubles. For Atlanta suitable K-59, for Indesit — Danfoss 077B6340.

⚠️ Attention: Do not leave the wires closed for a long time - this can burn the compressor! Use this test for diagnostic purposes only.

4. Clogged capillary tube: how to clean it without a technician

If the refrigerator is freezes slightly or only in one department, it is to blame clogging in the capillary tube. This is a thin copper tube through which freon circulates. Over time, it becomes clogged with oil or moisture.

Signs of a blockage:

• ❄️ The freezer works, but the refrigerator compartment does not (or on the contrary).
• 🔥 The compressor is hot, but does not turn off.
• 💧 The condenser (grid at the back) is cold.

You can clean the tube without disassembling the systemif the blockage is not severe. You will need:

• 🔧 10mm wrench.
• 🧴 Acetone or solvent.
• 💨 Compressor for inflating wheels (or pump).

Step-by-step instructions:

1. Disconnect the refrigerator and drain the freon (if you are not sure, it is better to call a technician).
2. Disconnect the capillary tube from the filter-drier (it is soldered, gently heat it with a soldering iron).
3. Connect to hose from the compressor in the tube and blow it in the opposite direction (from the evaporator to the compressor).
4. Rinse the tube with acetone and blow it again.
5. Solder it back and fill with freon.

If the blockage is severe, it will be required replacing the capillary tube (this is done in the service).

What will happen if you do not clear the blockage?

If you ignore the problem, the compressor will wear out and burn out in 1-3 months. The repair will cost 5–8 thousand rubles (versus 1–2 thousand for cleaning the tube).

5. Problems with the fan and the No Frost system

In refrigerators No Frost (Samsung RB37, LG GA-B489) the fan is responsible for air circulation. If it breaks, the freezer will work, but the refrigerator will not.

How to check the fan:

1. Unplug the refrigerator and remove the back panel in the freezer.
2. Find the fan (plastic impeller behind the motor).
3. Twist the blades by hand - they should rotate easily, without squeaking.
4. Connect the refrigerator to the network and listen: if the fan does not make noise, it has burned out.

Replacing the fan costs 1,500–3,000 rubles. For Samsung suitable DA97-06013A, for LG — 6601JB1006A.

Another common problem No Frost — icing of the evaporator. This is due to:

• 🔌 Faulty defrost timer (needs to be replaced).
• 🌡️ Burnt defrost heating element (call with a multimeter).
• 💧 Blockage in drain holes (clean with wire).

6. A two-chamber refrigerator does not freeze: specifics of repair

If you have a two-compressor refrigerator (Liebherr CN 4015, Bosch KAN92VI30and only one chamber does not work, the problem may be in:

• 🔌 Separate compressor for a freezer/refrigerator.
• 📶 Control unit (it regulates both motors).
• 🔗 Freon lines (leak in one circuit).

How diagnose:

1. Listen to whether the compressor of the faulty chamber is working (it should vibrate slightly).
2. Check whether the condenser of this chamber (rear grill) is heating up.
3. If the compressor does not start, the problem is in starting relay or motor winding.

In two-chamber refrigerators with one compressor (Atlant MHM-170) is most often to blame switching valve between the chambers. Replacing it will cost 2000–3500 rubles.

⚠️ Attention: In models with linear compressor (LG Door-in-Door) independent repair is fraught with damage to the electronics. Here it is better to call a specialist.

7. When to call a specialist: 3 cases when amateur performance is dangerous

Some breakdowns require professional equipment and experience. Don't take risksif:

1. Freon refilling is required. Without a vacuum pump and pressure gauges, you will not be able to prime the system properly. An error will lead to a repeated leak.
2. The compressor winding has burned out.. If the motor does not start and it smells like burning, a replacement will be required (cost - 4000–8000 rubles).
3. The control board is “burned out”. If blackened elements or swollen capacitors are visible on the board, you need a soldering station and circuits.

The average cost of a technician’s visit is 1500–2500 rubles. But if the problem is clogged tube or faulty thermostat, you will save 3-5 thousand rubles by doing the repair yourself.

8. Temporary measures: how to preserve food while the refrigerator is not working

If repairs are delayed and there are perishable foods in the freezer, use these tips:

• ❄️ Transfer the food to a cooler bag with cold batteries (keep the temperature up to 12 hours).
• 🧊 Cover the food with bottles of frozen water —this will slow down the thawing.
• 🍖 Meat and fish wrap it in foil and place it in a bowl of cold water (change the water every 2 hours).
• 🥛 Dairy products pour into a thermos or plastic bottles and place in a bucket of ice.

Do not put food on the balcony in winter: at temperatures higher -5°C they will begin to deteriorate.

If the refrigerator is not is freezing, but you are not sure of the reason - use test with a thermometer:

1. Place an outdoor thermometer in the freezer.
2. Close the door for 2 hours.
3. If the temperature is higher -10°C —the problem is serious, if below -15°C —the settings may have gone wrong.

FAQ: Frequently asked questions about refrigerators that do not freeze

The refrigerator hums, but does not freeze - what could it be?

Most likely, the problem is start relay or condenser. If the compressor hums for 2-3 seconds and turns off, the relay does not start the engine. If the humming is constant, but there is no cooling, there is a blockage in the capillary tube or a freon leak.

The freezer is working, but the refrigerator is not - what's the matter?

In 90% of cases guilty clogged capillary tube or faulty fan (in models No Frost). Less commonly, a freon leak in the refrigeration chamber circuit or a breakdown of the switching valve (in two-chamber models).

The refrigerator stopped freezing after turning off the lights. What to do?

Probably the control board settings have gone wrong. Try reset the error: turn off the refrigerator for 10 minutes, then turn on and hold the button Super Cool (or Freeze) 15 seconds. If it doesn’t help, a flashing is required.

Is it possible to repair the refrigerator yourself if it is under warranty?

No. Any intervention in the design (even replacing a light bulb) voids the warranty. Contact the service center - the repair will be free if the breakdown is not your fault.

How much does the repair cost if the refrigerator does not freeze?

The price depends on the breakdown:

• Replacement of the thermostat - 800–1500 rub.
• Cleaning the capillary tube — 1500–2500 rub.
• Refilling freon — 2000–4000 rub.
• Replacement of the compressor — 4000–8000 rub.
• Repair of the control board - 2500–5000 rubles.
