The situation when upper chamber of the refrigerator stops cooling food often takes owners by surprise. You open the door, and it’s warm there, while the lower compartment can work properly or, conversely, also remain silent. In models Samsung with the system No Frost this is especially noticeable, since the circulation of cold air is disrupted throughout the entire volume.
There is no need to panic right away. In most cases, the problem lies in a simple electronics failure or violation of operating rules, which can be easily fixed on your own in a few minutes. However, there are also more complex technical faults that require the intervention of a specialist.
Next we will analyze in detail the algorithm of actions: from initial diagnostics to checking complex components. Correct diagnosis will help save money on unnecessary repairs or, conversely, quickly call a technician if the problem is serious.
⚠️ Attention: If you smell burning, see sparking, or hear a loud cracking sound, immediately unplug the refrigerator. Further operation may be dangerous.
Primary diagnostics and checking settings
Before looking for breakdowns inside the unit, it is necessary to exclude the human factor. Often, users accidentally touch the control panel or change operating modes without realizing the consequences. Make sure that the mode "Vacation" (Eco/Travel)is not activated, in which the upper chamber may not be cooled to save energy.
Check the temperature settings. For normal storage of food in the refrigerator compartment, the temperature should be in the range from +3 to +5 degrees. If you set the minimum value, and the food still spoils, this is a clear sign of a malfunction of the cooling system.
- 🔍 Check whether the control panel is locked (Child Lock function).
- ❄️ Make sure that the selected mode corresponds to the current load of products.
- 🔌 Try restarting the device, by disconnecting it from the network for 10-15 minutes.
Sometimes a simple reset of electronic errors helps. Unplug the refrigerator, wait 15 minutes and plug it back in. If after a few hours temperature mode has not recovered, proceed to the next stage of testing.
Problems with the door and seal
One of the most common reasons why The upper chamber does not freezeis a loose fit of the door. Warm air from the room constantly flows inside, and the unit simply does not have time to cool it. The compressor works for wear, but the desired cold is not achieved.
Carefully inspect rubber seal around the perimeter of the door. There should be no cracks, creases or dirt on it that would interfere with hermetically sealed closure. Even a small crumb or sticky trace of juice can damage the insulation.
Also check the door hinges. Over time, they can sag, especially if you often open the refrigerator with its full weight or load the door shelves with heavy bottles. The skew of the door is visually noticeable: one side fits tighter than the other.
⚠️ Attention: If the seal is damaged, do not try to glue it with superglue. This will not restore elasticity, but will only ruin the part. A complete replacement of the cuff is required.
Clogging of the condensate drainage and ventilation system
In refrigerators Samsung No Frost cold air is forced by a fan from the evaporator into the chambers through special air ducts. If these channels are clogged with food, packaging or ice, circulation stops. As a result, upper chamber stops receiving cold, although the compressor is running.
A situation often occurs when the drainage hole or melt water drainage channel freezes. Ice blocks the path of air. This can happen if you put hot food in the chamber or rarely defrosted it (even in the No Frost system, preventive defrosting is necessary once a year).
To check this version, look in the back wall of the refrigerator compartment. If you see ice or “fur coat” in certain places, it means that the ventilation system is broken. It is necessary to defrost the unit completely (at least 24 hours with the doors open).
- 🧊 Defrost the refrigerator completely within 24 hours.
- 🧹 Clean the drainage hole with warm water (you can use a syringe).
- 💨 Blow out the ventilation holes (carefully, without use of sharp objects).
☑️ Defrosting algorithm
Blower fan malfunction
If after defrosting the problem returned after a couple of days, it may have failed evaporator fan. It is he who drives cold air from the freezer (or from a hidden unit) to the upper compartment. If the fan is standing, there will be no cold at the top.
You can tell that the fan is not working by the silence. In a working refrigerator No Frost the noise of a running fan is periodically heard. If you do not hear the characteristic hum of air, but the compressor is humming, most likely the problem is in the blower motor.
Sometimes the fan jams due to frozen ice on the blades. This often happens if the defrost sensor or evaporator heating element is faulty. Ice builds up, blocks the impeller, and the motor burns out or simply stops.
⚠️ Attention: Replacing the fan requires partial disassembly of the rear wall. If you do not have experience working with electrical appliances, it is better to entrust this to a specialist so as not to damage the plastic latches of the case.
Failure of the control module and sensors
Modern refrigerators Samsung are stuffed with electronics. The temperature is controlled by sensors (thermostats), which send signals to the main control module. If one of the sensors is “lying” or has failed, the module may “think” that there is enough cold and does not turn on the compressor or fan.
Most often, the temperature sensor of the refrigerator compartment in the upper compartment fails. It may show underestimated values, which is why the cooling system simply does not start. A failure in the control board itself is also possible, especially if there have been power surges in the network.
To accurately diagnose sensors, you need a multimeter and knowledge of the resistances of specific models. However, an indirect sign may be the blinking of indicators on the panel or the appearance of error codes on the display (for example, errors of the 22C, 24C series and the like, depending on the model).
Typical Samsung error codes
22C / 22E - refrigerator temperature sensor error. 24C / 24E - refrigerator defrost sensor error. If you see these codes, the problem is almost certainly in the electronics or sensors.
Table of main symptoms and causes
For ease of diagnosis, let's summarize the main symptoms in a table. This will help you quickly navigate the nature of the breakdown.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Warm at the top, cold at the bottom | Fan faulty blowing or the channel is clogged | Average |
| It’s cold, but the food freezes | The temperature sensor or thermostat is faulty | Average |
| It hums, but does not get cold nowhere | Freon leak or compressor breakdown | High |
| There is a lot of ice/snow on the walls | The defrost system is faulty (heating element, timer, sensor) | Average |
As can be seen from the table, problems with air circulation occur most often. They are the easiest to solve. However, if it comes to a refrigerant leak, independent repair is impossible without special equipment.
Freon leak and compressor breakdown
These are the most serious and expensive faults. If refrigerant (freon) has evaporated through a microcrack in the circuit, there is nothing to cool. The compressor may run continuously, trying to build up the temperature, but there will be no result.
Signs of a leak: the condenser (grid at the back or on the sides) remains cold or only partially warm, and not hot, as it should be when operating. An oily stain may also appear on the floor under the refrigerator where the tubes exit.
A compressor breakdown is accompanied by either complete silence (if the winding is burned out) or a loud hum and clicking (if the mechanism is jammed). In both cases, a call to a technician is required to replace the unit and refill the system.
⚠️ Attention: Repairs related to a sealed circuit (compressor replacement, leak detection, freon refilling) require a license and special tools. Getting into the circuit yourself is dangerous and pointless.
When to call a specialist?
Let's summarize. If you have completed all the initial diagnostic steps (checked the settings, defrosted, checked the seal), but upper chamber it still does not work, it’s time to call service. Especially if you hear strange sounds or see error codes.
A professional technician will conduct diagnostics using instruments, check the pressure in the system, the resistance of the sensors and the integrity of the electrical circuits. This will allow you to accurately determine the reason and cost of the repair.
Do not delay the repair. An idling compressor can burn out if there is a freon leak, turning a simple repair into a replacement of an expensive unit. Take care of your equipment!
☑️ Checklist before calling a technician
Why, after defrosting, did the refrigerator stop freezing again after 2 days?
This is a classic sign of a malfunction of the automatic defrosting system. Most likely, the evaporator heating element, defrost sensor or timer burned out. Ice again accumulates in the hidden block and blocks the air supply channels.
Is it possible to temporarily use the refrigerator if the upper chamber does not freeze?
It can be used, but with restrictions. Perishable foods cannot be stored in the upper compartment. The compressor will work constantly, which will lead to overheating and increased energy consumption. This is a temporary solution until the technician arrives.
How much does the repair cost if the fan burns out?
The cost consists of the price of the spare part (a fan for Samsung is relatively inexpensive) and the work of the replacement technician. The exact amount will be announced in the service center after diagnostics, but this is not the most expensive type of repair.
Does the position of the refrigerator affect the operation of the upper chamber?
Yes, if the refrigerator is tilted strongly, the door may not close tightly on its own. The distance from the wall for ventilation of the condenser is also important. If it's hot behind you, the cooling efficiency drops.
