The freezer freezes, but the refrigerator does not work: reasons and solutions

Have you opened the refrigerator, and there is room temperature, although the freezer continues to freeze food properly? This situation occurs more often than it seems. The reasons can be either trivial (forgot to close the door) or serious (failure of key components). In this article we will look at why all possible faults, according to which the freezer compartment works, but the refrigerator compartment does notand also give step-by-step instructions for diagnostics and repair.

It is important to understand: modern refrigerators (even budget models Atlant, Indesit or Samsung) are designed in such a way that the freezer and refrigerator compartments are often connected by a common cooling system, but are controlled separately. If one of the compartments stops working, this does not always mean a global breakdown. Sometimes the problem is solved in 10 minutes —it is enough to remove the blockage or reset the settings.

Before calling a technician or taking the equipment to a service center, go through our checklist. We have collected unique signs of each breakdownthat will help more accurately determine the source of the problem. For example, if the compressor hums continuously, but the refrigerator does not cool, this is one scenario, and if it periodically turns off, it is a completely different one.

1. A clogged capillary tube is the most common cause.

The capillary tube (or capillary choke) is a thin copper channel through which the refrigerant (freon) flows from the condenser to the evaporator. If the tube becomes clogged, freon cannot circulate normally, and the refrigerator compartment stops cooling, while the freezer is still “held” by the residual refrigerant.

Signs of clogging:

• 🔊 The compressor runs without stopping or turns on for a short time (5-10 seconds) and turns off.
• ❄️ The freezer compartment freezes slightly (the temperature is higher than usual, but not critical).
• 🌡️ The refrigerator compartment is warm, although the fan (if any) works.

How check:

1. Disconnect the refrigerator from the network for 1-2 hours so that the pressure in the system equalizes.
2. Turn it on again and touch condenser (the grill at the back or bottom). If it is uniformly warm, the blockage is confirmed. If one part is hot and the other cold, the problem lies elsewhere.

⚠️ Attention: Do not try to clean the capillary tube yourself using wire or pressurized air! This may damage the system. It is better to call a specialist with professional equipment for purging with nitrogen.

What is a capillary tube and why does it clog?

A capillary tube is a long narrow channel (~0.6–1.2 mm in diameter) that regulates the flow of freon. The blockage occurs due to:

- Moisture entering the system (an ice plug is formed).

- Decomposition of the compressor oil (solid deposits are formed).

- Mechanical particles (for example, after unqualified repairs).

2. Freon leak - when the refrigerator “loses its cool”

Freon is a refrigerant that circulates through the system and removes heat. If a microcrack appears somewhere in the circuit (most often at soldering points or on the evaporator), the gas gradually evaporates. The freezer can still work because it is closer to the compressor and receives residual freon, and the refrigerator compartment remains without cooling.

Signs of a leak:

• 🕳️ The compressor works almost non-stop, but the refrigerator does not cool.
• 🧊 On the back wall of the refrigerator there is no frost in the compartment (if the model is with a drip system).
• 🔧 Visible traces of oil near the tubes or rust on the body (with a long-term leak).

How to diagnose:

1. Turn off the refrigerator and inspect solder points on the back wall (especially compressor and filter drier). Look for oil stains or bubbles when turning on (you can apply a soap solution).
2. If the leak is in evaporator (hidden behind the plastic panel), it can only be detected using a leak detector.

⚠️ Attention: If a freon leak occurs due to corrosion of aluminum tubes (often in models LG or Whirlpool with the system No Frost, repairs may be unprofitable. In such cases, technicians recommend replacing the evaporator or the entire refrigeration unit.

3. Failure of the thermostat or temperature sensor

The thermostat (or thermostat) is the “brain” of the refrigerator, which controls the temperature and sends signals to the compressor. If it fails, the compressor either does not turn on at all or operates chaotically. In two-compressor models (for example Liebherr or Beko), only the thermostat of the refrigerator compartment may break, while the freezer will work normally.

Signs of a thermostat malfunction:

• 🔄 The compressor turns on for 1-2 seconds and immediately turns off (relay clicks are heard).
• 🌡️ The temperature in the refrigerator rises, despite the maximum cooling settings.
• 💡 The light inside is on, but there is no cooling (in models with electromechanical control).

How to check the thermostat:

1. Unplug the refrigerator and remove the thermostat protective casing (usually located inside the refrigerator compartment or on the top panel).
2. Find two wires going to the thermostat and short them together (after photographing the circuit first!). If the compressor starts working, the thermostat is faulty.
3. For electronic models (for example, Samsung RL-60) you will need a multimeter: check the resistance of the sensor at room temperature and in the cold (should change).

Disconnect the refrigerator from the mains

Remove the lid thermostat

Close the thermostat contacts (for testing)

Ring the sensor with a multimeter (for electronic models)

4. Problems with the fan (for No Frost models)

In refrigerators with a system No Frost (for example, Bosch KGE39XW25R or Electrolux ERN1200FOX) the fan is responsible for circulating cold air. If it breaks or freezes, the cold stops flowing into the refrigeration compartment, although the freezer continues to work (it has its own evaporator).

Signs of a fan malfunction:

• 🌀 There is no airflow in the refrigeration compartment (usually a slight buzzing sound is heard).
• 🧊 There is a thick layer of ice on the back wall of the freezer (the fan is frozen and blocked).
• 🔊 The refrigerator has become quieter, but there is no cooling.

How to fix:

1. Defrost the refrigerator for 12-24 hours (completely disconnected from the network). Often this is enough for the ice to melt and the fan to start working again.
2. If defrosting does not help, check whether the fan blade rotates manually (with the power off!). If not, the motor winding may break.
3. In models with double fans (separately for the freezer and refrigerator), check both. For example, in Samsung RB-30 J3200SA they are located behind the rear panel of the freezer.

5. Malfunction of the compressor or start relay

The compressor is the “heart” of the refrigerator, which pumps freon through the system. If it fails or cannot start due to breakdown start relay, cooling stops. In two-compressor models (for example Atlant MHM-2808), only the refrigerator compartment compressor may break down, while the freezer will work normally.

Signs of problems with compressor:

• 🔇 The compressor does not turn on at all (no sound or vibration).
• 🔥 The relay clicks, but the motor does not start (start attempts are heard).
• 🌡️ The compressor housing is excessively hot (over 70°C).

Diagnostics and repair:

1. Check starting relay (black box on the compressor). It often burns out due to power surges. Test it with a multimeter or replace it with a known working one.
2. If the relay is working properly, measure the resistance of the compressor windings:
   • Between the contacts C-S (working winding) - it should be 15–40 Ohm.
   • Between C-R (starting winding) - 20–50 Ohm.
   • Between S-R - the sum of the two previous values.

If the windings are in break or short circuit - the compressor must be replaced.

⚠️ Attention: In modern inverter compressors (for example, in LG GA-B489YDQZ), diagnostics are more complicated - they are controlled by an electronic unit. You can't do without a specialist here. An attempt to “ring” such a compressor with a multimeter may give false results.

6. Clogged drainage system of the refrigeration compartment

If in a refrigerator with a drip defrosting system (not No Frost) it becomes clogged drainage hole, the water does not go into the pan, but accumulates under the vegetable drawers. This leads to freezing of the evaporator and disruption of heat exchange. The freezer works normally, since it has a separate circuit.

Signs of clogged drainage:

• 💧 Puddle under the lower drawers of the refrigerator compartment.
• ❄️ Ice on back wall (even if the thermostat is set to +5°C).
• 🌡️ The temperature in the compartment rises, although the compressor is running.

How to clean the drainage:

1. Turn off the refrigerator and remove all shelves/drawers.
2. Find the drainage hole (usually in the center of the back wall above the vegetable tray).
3. Clean it using:
   • A special brush (included with some models).
   • A plastic tube or straw.
   • Syringes with warm water (under pressure).

Rinse the hole with a soda solution (1 tablespoon per glass of water) to remove mucus.

7. Electronic failures: control board or firmware

In refrigerators with electronic control (for example, Samsung Family Hub or Haier C2F636CWM) is responsible for cold distribution. main board. If it fails or the firmware is faulty, a situation may occur where the freezer works but the refrigerator does not. This is often accompanied by errors on the display (for example, E1, FF or dH).

Signs of an electronic failure:

• 📛 An error flashes on the display (see the instructions for the model).
• 🔄 The refrigerator reboots spontaneously.
• 🎛️ The control buttons do not respond or work with a delay.

What to do:

1. Reset the settings to factory settings: turn off the refrigerator for 5 minutes, then turn it on and hold down the button Super Freeze (or similar) for 10 seconds.
2. If there is a display, check the error code in the instructions. For example, in Bosch error E01 means a problem with the temperature sensor.
3. Update firmware (relevant for “smart” models). Instructions are usually available on the manufacturer’s website.

⚠️ Attention: If the control board fails due to a power surge, replacing it can cost 30–50% of the cost of a new refrigerator. In such cases, it is more advisable to consider purchasing new equipment, especially if the model is older than 7 years. data-i="209">FAQ: Frequently asked questions about a non-working refrigerator

FAQ: Frequently asked questions about a refrigerator not working

The freezer is freezing, but the refrigerator is not - what should you do first?

Start with simple checks:

1. Make sure that the refrigerator door is tightly closed (there is no distortion or interfering items).
2. Check whether the mode Super Freeze or Vacation (in some models it turns off the refrigeration compartment).
3. Defrost the refrigerator for 12 hours - the fan or drainage may be frozen.

If this does not help, proceed to diagnosing the thermostat, compressor or freon leak.

Is it possible to fill the refrigerator with freon yourself?

No, this is dangerous and requires special equipment, and moisture or air may remain in the system, which will lead to re-clogging. some types of freon (for example R-600a) are flammable and explosive if handled incorrectly.

Exception: if you have experience working with refrigeration equipment and a vacuum pump, you can try. But in 90% of cases this leads to aggravation of the problem.

How much does it cost to repair if it doesn't work. refrigerator, but the freezer freezes?

The cost depends on the reason:

Breakage	Repair cost (rub.)	Cost of spare parts (rub.)
Replacement thermostat	1 500–2 500	800–1 500
Cleaning the capillary tube	3 000–5 000	500 (freon + oil)
Freon leakage (soldering + refilling)	4 000–7 000	1 000–2 000
Replacing the compressor	5 000–10 000	6 000–12 000

Prices relevant for Moscow and regional service centers. In small cities, repairs can cost 20–30% less.

How to check if the refrigerator compressor is working?

Checking methods:

1. By hearing: when the compressor is running, you can hear a slight hum and vibration. If it does not turn on - silence.
2. To the touch: touch the compressor housing (the black “barrel” on the back). If it is cold, it does not work; if it is hot (but does not burn), it works.
3. Using a multimeter:
   • Turn off the refrigerator, remove the start relay.
   • Ring the windings (the resistance between the contacts should be 15–50 Ohms).

Can the refrigerator not cool due to a power surge?

Yes, this is one of the most common causes of failure start relay or control boardSymptoms:

• The refrigerator suddenly stopped work after a thunderstorm or a power outage.
• The compressor tries to start, but immediately turns off (clicks are heard).
• An error flashes on the display (for example, PF — power failure).

Solution: replace the relay (costs ~1,000 rubles) or install voltage stabilizer (from 3,000 rubles).
