The freezer is freezing, but the refrigerator is not cold: reasons and what to do

You opened the refrigerator, and there is room temperature, although the freezer is working properly freezing? This problem is familiar to many owners of two-chamber refrigerators. The situation is not only annoying (food spoils in a matter of hours), but also mysterious: why does one part of the unit work and the other not? The reasons may lie in both trivial operating errors and serious breakdowns that require the intervention of a technician.

In this article we will look at why the freezer freezes but the refrigerator does not cool - from a clogged drainage system to failure of the electronic module. You'll learn how to diagnose the problem yourself, when you can get by with a simple tune-up, and when it's time to call a repairman. We will also give a checklist for emergency actions to save food before the refrigerator starts working. all possible reasons, due to which the freezer freezes, but the refrigerator does not cool - from a clogged drainage system to failure of the electronic module. You'll learn how to diagnose the problem yourself, when you can get by with a simple tune-up, and when it's time to call a repairman. We will also provide a checklist for emergency actions to save food before the refrigerator starts working.

Important: if your refrigerator is No Frost or with a system Low Frost, some reasons will be specific to these technologies. We will separately note such cases. And for owners of older models with a drip defrosting system, we have separate recommendations.

1. Clogged drainage or blockage in the air circulation system

One ​​of the most common reasons why the refrigerator does not cool, but the freezer works - problems with cold air circulation. In two-chamber refrigerators, the cooling of the refrigerator compartment occurs due to the air that comes from the freezer through special channels. If these channels are clogged, the cold simply does not reach the upper chamber.

Most often clogged:

• 🔹 Drainage hole - clogged with crumbs, food particles or ice. The water does not drain, ice forms, which blocks the air flow.
• 🔹 Ventilation grilles between the compartments - dust, grease, food residues accumulate on them.
• 🔹 Freezer evaporator - if there is too much a lot of ice (especially in models No Frost), this blocks the fan.

How to check? Open the freezer and look for a thick layer of ice or snow on the back wall. Next, check the drainage hole in the refrigerator compartment (usually located on the back wall near the shelf). If water has accumulated there or debris is visible, the problem has been found.

De-energize the refrigerator|Remove all food from the refrigerator compartment|Clean the drainage hole with a cotton swab or a special brush|Rinse the grates between the compartments with warm water and soda|Defreeze the refrigerator for 10–12 hours (if there is ice)|Check the work after switch-->

⚠️ Attention: If your refrigerator has a No Frostsystem, never use sharp objects to clean the vents! This may damage plastic parts and fan blades. It is better to use a vacuum cleaner with a narrow nozzle.

2. Malfunction of the blower fan

The fan is a key element in refrigerators with the system No Frost or Frost Free. It is responsible for the uniform distribution of cold air between the freezer and the refrigerator compartment. If the fan is broken or its blades are blocked by ice, the cold will stop flowing into the upper chamber, although the freezer will work as usual.

Signs of a fan malfunction:

• 🔊 The refrigerator has become quieter (no characteristic fan noise).
• ❄️ In the freezer too much ice on the back wall (clogs the blades).
• 🌡️ The temperature in the refrigerator compartment is rising, but in the freezer it is normal or even lower than normal.

How to diagnose:

1. Open the freezer and listen: if the fan is working, you will hear slight hum or air noise.
2. Shine a flashlight on the back wall of the freezer - if the fan blades do not rotate or are covered with ice, the problem is confirmed.
3. Try to manually turn the blades (after turning off the power to the refrigerator!). If they do not rotate, it means the fan is blocked or the motor is burned out.

Solution:

• 🔧 If the blades are blocked by ice, defrost the refrigerator for 12-24 hours, then check the operation of the fan.
• 🛠️ If the fan does not work even after defrosting, the motor will need to be replaced (this is done by the master).

What will happen if you ignore a fan breakdown?

Without blowing, cold air will not flow into the refrigeration compartment, which will lead to food spoilage. In addition, the compressor will work in increased mode, trying to compensate for the lack of cooling. This can cause overheating and failure of the compressor - and this is already an expensive repair (up to 70% of the cost of a new refrigerator).

3. Failure of the thermostat or temperature sensor

The thermostat (or thermostat) and temperature sensors are responsible for controlling the climate in the refrigerator. If they fail, the compressor may not work correctly: either not turn on at all, or freeze only the freezer, ignoring the refrigeration compartment.

How the breakdown manifests itself:

• 📉 The temperature in the refrigerator compartment rises, although the freezer is freezing.
• 🔄 The compressor works without stopping or, on the contrary, almost does not turn on.
• 🔊 Clicks or crackling sounds appear when you try to adjust the temperature.

The easiest way to check the thermostat is switch the temperature controller to maximum and listen. If the compressor does not respond (won't turn on or change operating mode), the thermostat is most likely faulty. In modern refrigerators (for example Samsung, LG, Bosch), instead of a mechanical thermostat, electronic sensors are used - checking them requires diagnostic equipment.

⚠️ Attention: If your refrigerator is equipped with an electronic control unit (for example, models Liebert, Indesit with a display), a faulty sensor may cause an error on the panel. Usually these are codes like E1, F2 or H1 - their decoding can be found in the instructions for the model.

4. Freon leak or clogged capillary tube

Freon is a refrigerant that circulates through the refrigerator system and provides cooling. If freon leak occurs or becomes clogged capillary tube (along which it moves), the compressor continues to work, but cold does not enter the refrigeration compartment. In this case, the freezer can still freeze for some time due to the remnants of freon.

Signs of a freon leak:

• 🔊 The compressor works without stopping, but the refrigerator does not cool.
• 🧊 Rust or oil stains appear on the back wall of the refrigerator (outside).
• 🌡️ The temperature in the freezer gradually increases (if the leak is severe).

A clogged capillary tube manifests itself in a similar way, but usually the problem develops gradually: at first the refrigerator cools poorly, then stops working altogether. Most often, blockage occurs due to moisture entering the system or wear of the compressor (metal shavings clog the tube).

⚠️ Attention: Freon leakage is a malfunction that cannot be fixed on your own. Freon is toxic, and its refilling requires special equipment. If you suspect a leak, contact a service center immediately. The average cost of repairs (refueling + leak detection) is from 3500 to 7000 ₽.

5. Problems with the compressor or start-up relay

The compressor is the “heart” of the refrigerator. If it is not working properly, it can cause the freezer to freeze but the refrigerator compartment not to freeze. Most often, problems with the compressor manifest themselves as follows:

• 🔊 The compressor hums, but does not start (relay clicks are heard).
• 🌡️ The freezer works, but is weaker than usual, and the refrigerator compartment does not cool.
• 🔥 The compressor housing is too hot (you can check it with your hand, but carefully!).

Causes of compressor malfunction:

• 🔋 Failure start-protection relay - it is responsible for starting the compressor. If the relay is broken, the compressor may not turn on or operate jerkily.
• 🛢️ Wear of the piston group - over time, the compressor loses power and cannot provide sufficient freon pressure to cool both compartments.
• 🔌 Problems with winding - if the compressor overheats or the protection is triggered, it may turn off a few minutes after starting.

How to check the compressor:

1. Unplug the refrigerator.
2. Remove the back cover (if there is one) and find the compressor (usually the black “barrel” in bottom part).
3. Check if there are any traces of oil or rust on it - these are signs of a leak.
4. Turn on the refrigerator and listen: if the compressor hums, but does not start, the problem may be in the relay.

⚠️ Attention: If the compressor does not start at all (no hum, no clicks), do not try to “reanimate” it by turning it on multiple times! This may cause a short circuit. It’s better to immediately call a technician for diagnostics.

6. Incorrect settings or operating errors

Sometimes the reason why the refrigerator does not cool, but the freezer works, lies in banal user errors. Before risking a breakdown, check:

• 🔢 Temperature mode — perhaps the refrigerator compartment regulator is accidentally turned to the minimum (or completely turned off). Some models (for example Atlant or Turquo) have separate controls for the freezer and refrigerator.
• 🚪 Door closure tightness — if the seal is worn out or the door is skewed, warm air penetrates the compartment, and the temperature rises. Check for any cracks: place a sheet of paper between the door and the body - if it falls out, the seal needs to be changed.
• 🍽️ Overloaded with food - if the refrigeration compartment is packed to capacity, air does not circulate and the temperature is distributed unevenly. This is especially true for models with No Frost.
• ☀️ External conditions - if the refrigerator is located next to a radiator, stove, or in direct sunlight, the compressor may not be able to cope with the load. Normal temperature for operation - 16–32°C.

Also check if the mode Super Freeze or Holiday (if it is in your model) is activated. In Holiday mode, the refrigerator compartment turns off, and the freezer continues to work - this is done to save energy when you are away for a long time.

Make sure that the refrigerator is plugged in and there is light inside|Check the temperature settings (knobs should be in position 2-4)|Inspect the door seal for damage|Make sure that that the ventilation openings are not blocked by food|Check that the error indicators on the panel are not lit-->

7. Failure of the electronic control module

In modern refrigerators with a display and electronic control (for example, Samsung RB37J5240, LG GA-B489) the electronic moduleis responsible for the distribution of cold. If it fails, strange malfunctions may occur: the freezer freezes, but the refrigerator does not, or vice versa, the temperature fluctuates for no reason.

Signs of a malfunction of the electronic module:

• 📱 Errors flash on the display (for example, Er IF, E3, F5).
• 🔄 The refrigerator switches modes spontaneously.
• 🔇 Does not respond to pressing buttons or touch panel.
• 🌡️ The temperature in the compartments does not correspond to the specified parameters.

What do:

1. Try reset settings - unplug the refrigerator for 10-15 minutes, then turn it on again. Sometimes this helps with temporary failures.
2. If the error on the display remains, find its explanation in the instructions. For example, Er IF in refrigerators Samsung indicates a problem with the fan.
3. If the module is faulty, it needs to be reflashed or replaced. This is done by a technician, the cost of repair is from 2500 to 6000 ₽.

⚠️ Attention: If your refrigerator under warranty, do not try to repair the electronic module yourself! This may void the warranty. Contact an authorized service center.

8. Clogged filter drier or problems with the cooling circuit

The filter drier is a small element in the cooling system that protects the compressor from moisture and If it becomes clogged, freon cannot circulate normally, and the refrigerator stops cooling. At the same time, the freezer may still work for some time, since it is closer to the compressor.

Signs of a clogged filter-drier:

• 🌡️ The temperature in the refrigerator compartment gradually increases, and the freezer remains normal.
• 🔊 The compressor works without stopping, but does not freeze.
• 🧊 Frost or condensation may appear on the back wall of the refrigerator (outside).

This problem cannot be diagnosed without special equipment. If the technician confirms that the filter is clogged, it will be detected. will have to be replaced, and the system will have to be refilled with freon. The average cost of such a repair is 4000–7000 ₽.

Problems may also be associated with depressurization of the circuit. cooling for example, if the tubes were damaged during transportation of the refrigerator. In this case, soldering of the circuit and refilling of freon will be required.

What to do if the refrigerator does not cool and the freezer is working: emergency measures

While you are diagnosing the problem or waiting for the technician, products begin to deteriorate in the refrigerator. To minimize damage:

• 🥩 Transfer perishable foods (meat, fish, dairy products) to the freezer - they will last longer there.
• 🧊 If the freezer is full, pack the food in airtight containers and cover them with ice (you can use frozen bottles). water).
• 🌡️ Do not open the refrigerator door unless necessary - this will slow down the rise in temperature.
• 🔌 If the refrigerator is not freezing at all, unplug it to avoid overheating of the compressor.

If you suspect that the problem is a clogged drain or ventilation, you can try defrost the refrigerator for 10-12 hours. After defrosting:

1. Wipe all surfaces dry.
2. Check the drainage hole and clean it.
3. Make sure that the ventilation grilles are not blocked.
4. Turn on the refrigerator and monitor the temperature for 6-12 hours.

⚠️ Attention: If the problem remains after defrosting, do not turn on the refrigerator again - this may worsen the breakdown.

FAQ: Frequently asked questions about the problem "the freezer is freezing, but the refrigerator is not"

Is it possible to fill the refrigerator with freon yourself?

No, refilling freon requires special equipment and skills. You can not only damage the refrigerator, but also cause harm to your health. In addition, before refueling, you need to find and eliminate the cause of the leak, otherwise the freon will leak out again.

How much does it cost to repair if the refrigerator does not cool and the freezer works?

The cost depends on the cause of the breakdown:

• Replacing the thermostat or sensor — 1500–3500 ₽.
• Repair or replacement of fan — 2000–4500 ₽.
• Refilling freon + eliminating leaks — 3500–7000 ₽.
• Replacement of compressor — 5000–12000 ₽.
• Repair of electronic module — 2500–6000 ₽.

The exact price can be found out only after diagnostics.

How often do you need to defrost a refrigerator with No Frost?

Refrigerators with the system No Frost do not require regular defrosting, but it is still recommended to defrost them 1-2 times a year for cleaning and prevention. This helps prevent ice buildup on the evaporator and vent blockages. If you notice that the refrigerator has become worse at cooling, defrost it for 10-12 hours - this often solves the problem.

Why does the refrigerator not cool after defrosting?

If after defrosting the refrigerator does not start to cool, possible reasons:

• The fan is blocked by ice (you need to wait for complete defrosting).
• The thermostat or temperature sensor has failed.
• Freon leaked during defrosting (if the refrigerator was transported or dropped).
• The compressor burned out due to overheating.

In this case, it is better to call a technician for diagnostics.

Can the refrigerator not cool due to power surges?

Yes, voltage surges can damage the electronic module or compressor. If your network frequently experiences voltage fluctuations, it is recommended to connect the refrigerator via stabilizer. Also check if the compressor protection is triggered (it may turn off a few minutes after starting).
