Why the freezer works good, but the refrigerator does not freeze well: reasons and solutions

Have you noticed that the freezer freezes food properly, but in the main compartment the temperature barely drops below room temperature? This problem is more common than it seems - and is not always associated with a serious breakdown. In 80% of cases, it is not technical malfunctions that are to blame, but operating errors or minor problems that can be fixed independently.

In this article we will analyze 7 main reasonswhy the refrigerator does not freeze well when the freezer is running - from trivial clogged drainage hole to complex breakdowns fan or temperature sensor. You will learn how to carry out diagnostics without calling a specialist, what manipulations you can do yourself, and in which cases you cannot do without professional repairs. We will pay special attention to models with the system No Frost —they have their own “weak points.”

We’ll warn you right away: if your refrigerator is a single-compressor models (and this is most household appliances), then the freezer and the main compartment are cooled by one circuit. This means that a problem with the refrigerator compartment can sooner or later “spread” to the freezer - so it is dangerous to ignore the problem.

1. A clogged drainage hole is the most common reason

If the refrigerator does not freeze well, but the freezer is working fine, first check drainage hole in the refrigerator compartment. It is located on the rear wall (usually at the bottom) and serves to drain condensate. When clogged, water accumulates and forms an ice plug that blocks the circulation of cold air.

How this manifests itself:

• 🔹 Ice or frost is visible on the back wall of the refrigerator
• 🔹 At the bottom of the chamber water accumulates (sometimes flows out onto the floor)
• 🔹 The compressor works almost non-stop, but the temperature does not drop

What to do:

1. Unplug the refrigerator.
2. Free the bottom shelf (if it interferes with access to hole).
3. Take syringe or syringe without a needle, fill it with warm water and rinse the hole under pressure.
4. For cleaning, use soft wire or a cotton swab (not metal objects!).
5. After cleaning, wipe the back wall dry.

If after cleaning the problem remains, the ice may have frozen in drainage hose (it leads to the condensate container on the back wall of the refrigerator). In this case, you will need to defrost the refrigerator for 10–12 hours.

2. Fan malfunction in No Frost systems

Refrigerators with a system No Frost (for example, models Samsung RB37J5240SA, LG GA-B489YQQZ or Indesit DF 5200 W) are equipped with a fan that evenly distributes cold air between the freezer and refrigerator compartment. If the fan fails or is blocked by ice, the cold stops flowing into the main compartment, and the freezer continues to work.

Signs of a fan failure:

• 🔊 The refrigerator has become quieter (no characteristic fan noise)
• ❄️ On the back wall freezer thick layer of ice (blocks the blades)
• 🌡️ The temperature in the refrigerator compartment rises, in the freezer it is normal

How to check:

1. Disconnect the refrigerator and defrost it for 12-24 hours.
2. After defrosting, turn on the device and listen: if after 5-10 minutes the fan noise does not appear, it is faulty.
3. In models with electronically controlled (for example, Bosch KGE39XW2AR), a fan error may be displayed on the display as a code E22 or F04.

How to get to the fan in No Frost?

In most models, the fan is located behind the rear panel of the freezer. To get to it, you need to remove the shelves, unscrew the panel fastenings and carefully move it. Be careful not to damage the blades!

If the fan is blocked by ice, defrosting may help. If it burns out, it will need replacement. In refrigerators with an inverter compressor (for example, Samsung RB30J3000WW), a faulty fan can lead to overheating of the motor and its failure.

3. Problems with the temperature sensor

The temperature sensor (thermistor) transmits data about the current temperature in the refrigerator compartment to the control board. If it fails or gives incorrect readings, the compressor does not work correctly: it either turns on too rarely or does not turn off at all. As a result, the freezer freezes, but the refrigerator does not.

Symptoms of a faulty sensor:

• 📉 The temperature in the refrigerator compartment fluctuates (either too low, then too high)
• ⚙️ The compressor operates in cycles of 1–2 minutes with frequent shutdowns
• 🔧 An error may appear on the display (for example, E1 or H1 in models Indesit)

How to check the sensor:

1. Find the sensor - it is usually located on the back wall of the refrigerator compartment (may be hidden under the plastic casing).
2. Disconnect the connector and measure the resistance with a multimeter. At room temperature (~20°C) it should be in the range 5–7 kOhm.
3. Place the sensor in a glass of cold water - the resistance should change. If not, the sensor is faulty.

In most cases, the sensor requires replacement. For models Atlant, Stinol or Beko suitable spare parts can be found by the article number indicated on the sensor body.

4. Freon leak or blockage of the capillary tube

Freon is a refrigerant that circulates through the system and provides cooling. If freon leak or a blockage occurs, the cold stops flowing into the system. the refrigerator compartment, and the freezer still operates for some time due to the remaining refrigerant. capillary tube, the cold stops flowing into the refrigerator compartment, and the freezer continues to operate for some time due to the remaining refrigerant.

Signs of a leak or blockage:

• 🛢️ The compressor is running without stopping, but the temperature does not drop
• 🔧 The condenser (grid on the back wall) remains cold
• 💨 It’s warm in the refrigerator compartment, weak cooling in the freezer (or also warm if the leak is strong)

What to do:

This is one of the few problems that cannot be eliminated on your own. You will need:

1. Diagnostics using pressure gauge (checking the pressure in the system).
2. Detecting the location of the leak (most often - in evaporator or door heating circuit).
3. Refilling freon (used in modern models R600a or R134a).

The cost of repairs depends on the model. For example, for refrigerators Liebherr or Miele refilling freon will cost 5-8 thousand rubles, and for budget ones Biryusa or Pozytron —3-4 thousand.

5. Breakdown of the magnetic valve (in single-compressor models)

B. in single-compressor refrigerators (for example, Samsung RL-34 EBMG or LG GA-B429SQQL) (or magnetic valve (or three-way valveis responsible for the distribution of cold between the freezer and the refrigerator compartment, and the refrigerator compartment remains). warm.

How to recognize the problem:

• ❄️ The freezer freezes (temperature below -20°C)
• 🌡️ In the refrigeration chamber +10°C and above
• 🔊 When switching modes, a click is heard, but the temperature does not change

Diagnostics and repair:

The valve is located next to the compressor (usually in the lower part refrigerator). You can only check it using tester - when voltage is applied (usually 12–24 Va click should be heard. If the valve is faulty, replace it with a new one.

In some models (for example, Whirlpool or Electrolux), the valve is included control unit, and its replacement requires flashing the board.

6. the tightness of the door seal

If the sealing rubber on the door of the refrigeration chamber is worn out or damaged, warm air constantly penetrates inside. The compressor tries to compensate for this, but the cold “escapes” through the cracks. The freezer can work normally, since its door opens less often.

How to check the tightness:

1. Take a sheet of paper (A4 format).
2. Place it between the seal and the refrigerator body.
3. Close the door and try to pull out the sheet. If it comes out without effort, the seal is leaky.

Causes of wear. seal:

• 🧴 Contamination with fat or food residues (rubber loses elasticity)
• ☀️ Exposure to direct sunlight (if the refrigerator is located next to a window)
• 🔄 Frequent opening of the door (especially in hot weather)

Solutions:

• 🧼 Clean the seal with soapy water and lubricate with silicone grease.
• 🔧 If the rubber is deformed, replace it (the cost of a new seal for Atlant or Saratos —from 1,500 rubles).
• 🧲 Check the magnets in the seal - they may demagnetize over time.

7. Incorrect settings or overloading of the refrigerator

Sometimes the problem lies not in a breakdown, but in incorrect settings or violation of operating rules. This is what can lead to poor cooling:

Also check:

• 📱 Temperature settings (in electronic models like Samsung RB33J3420BC you can set the mode through the application).
• 🔌 Network voltage - at low voltage (180–190 V), the compressor works ineffectively.
• 🌬️ Distance to the wall - if the refrigerator is standing close, ventilation is disrupted condenser.

What to do if nothing helps?

If you have checked all possible reasons, but the refrigerator is still bad freezes, but the freezer is working normally, which means the problem is more serious. Here's what could be:

• 🔧 Failure of the control board (diagnostics and flashing or replacement are required).
• 🛠️ Failure of the compressor (in this case, the freezer will also stop working).
• 🔌 Open circuit of the power supply (checked with a multimeter).

In these cases Professional repair is required. The average cost of diagnostics is from 1,000 to 2,500 rubles, depending on the region. It is better to trust the replacement of components (board, compressor) to certified service centers, especially if the refrigerator is under warranty.

Before the technician’s visit:

1. Write down the model of the refrigerator (located on the sticker inside the chamber or on the back).
2. Describe the symptoms in as much detail as possible (when the problem appeared, what you have already tried).
3. If the refrigerator displays an error on the display, take a photo of it.

How to find a good repairman?

Look for service centers with a license to repair your brand (for example, for Bosch or Siemens this is important). Check reviews on Yandex.Maps or 2GIS. Avoid “handicraft” specialists who offer refilling freon without diagnostics - this can aggravate the problem.

⚠️ Attention: If your refrigerator was manufactured before 2010, it may use refrigerant. R12 or R22, which is prohibited for production. In this case, repairs with refilling freon will cost more due to a shortage of refrigerant.

FAQ: Frequently asked questions about the problem

🔹 Can a refrigerator freeze poorly due to a dirty condenser?

Yes, if the grill on the back wall of the refrigerator is clogged with dust or wool, the heat dissipation is disrupted and the compressor works less efficiently. Clean the condenser with a soft brush or vacuum cleaner (at least 2 times a year).

🔹 Why did the refrigerator become worse after defrosting?

Possible reasons:

• During defrosting they damaged capillary tube (if they used sharp objects to remove ice).
• The shelves or containers blocking ventilation were installed incorrectly.
• After defrosting, the seal did not dry out and it froze to the body.

Check the tightness of the door and the distribution of products in the chamber.

🔹 Is it possible to fill freon into the refrigerator yourself?

No. Charging freon requires special equipment (vacuum pump, pressure gauge, refrigerant bottle) and skills. Incorrect filling can lead to:

• Damage to the compressor.
• Freon leakage and environmental pollution.
• Fire hazard (freon R600a explosive!).

🔹 How much does it cost to repair if the refrigerator does not freeze, but the freezer works?

The cost depends on the reason:

• Cleaning the drainage or replacing the seal - 1,000-2,500 rubles.
• Replacing the temperature sensor - 1,500-3 000 rub.
• Fan repair (No Frost) — 2,000–4,000 rub.
• Replacement of the magnetic valve — 2,500–5,000 rub.
• Refilling freon - 3,500–8,000 rubles.

Service centers often offer free diagnostics for further repairs.

🔹 How to temporarily store food if the refrigerator does not freeze?

If repairs are delayed and the refrigerator is not cooling:

• Transfer perishable foods to the freezer (pack them in airtight containers).
• Use cooler bag or thermal container with ice.
• Store food in the coldest area (usually the shelf above the vegetable compartment).
• Do not open the door unless necessary.

Remember: at temperatures above +6°C, food spoils 2-3 times faster.
