Why the side walls of the refrigerator heat up
Why the side sides of the refrigerator heat up, which causes this problem and how to eliminate it.
The side walls of your refrigerator can heat up. There are some things that you can do to fix this, but there may be cases when you need to contact the master. This happens if the temperature is too high or the air is poorly circulating. Do not allow overheating, make sure that the temperature does not exceed 45 ° C (113 ° F).
This article tells about the reasons why the side walls of some refrigerators heat up. We will also talk about ways to solve this problem. This article tells how to avoid heating.
Refrigerators with the No Frost system can cool products without hoarfrost. They have Low Frost option for quick cooling of products. The refrigerator with the Low Frost system can use both methods at the same time. The question of why the side wall of the nofrost refrigerator is heated is incorrect.
Briefly, the No Frost system works due to air injection into the department. Units with the Low Frost system work differently.
Some manufacturers use Low Frost technology, but do not call it that. The labels differ depending on the type of circuit location. There are three different types of schemes that people use for their refrigeration systems. Total No Frost, Auto Defrost and Manual Defrost. Samsung, LG and Haier use one or another system type.
Why your chest freezer feels warm
If the refrigerator heats up on the sides, check in which place the heat exchanger is located. If it is located around the entire perimeter of the freezer or refrigerator, this is normal. If it has heated too much, perhaps the problem is in it.
Banal reasons that you did not know about
Sometimes your refrigerator does not work because its side walls are too hot. There are several reasons why this is happening. If this happens, it can be fixed and prevented in the future.
The temperature in the room
The warmer in the room, the less cold inside the refrigerator. The compressor works more and faster, if there is a big difference between how cold it is inside and outside.
The more the compressor works, the more heat exchanger heats up. Heat is transmitted to the walls, and they become hot. When it is very hot outside, the walls are cooled worse.
If you return from the store and start laying food in the refrigerator, the temperature in the departments will increase much. The compressor will have to work much more. As a result, not only the refrigerator is heated, but also the walls.
So you can’t fill the refrigerator categorically.
Hot in the cell
Some people put hot food in the refrigerator. This is bad. Because of this, it becomes hotter inside the refrigerator. The device has to work more intensively to compensate for this and restore the operating temperature.
As a result. overheating of the heat exchanger and side walls. And other negative consequences can be.
When the function is turned on, it makes products in the refrigerator or freezer cool. A lot of energy can be spent for this. The side walls can heat up, since the refrigerator has to work hard.
If you do not turn off this function and forget to do this, then it is clear why the sides of the refrigerator are hot. If this mode does not turn off automatically, then you need to find a refrigerator repair master.
Why the side walls and partitions between cameras heat up
First deal with the structure of your technique or look into the instructions. In Soviet.made refrigerators, a grille was located on the back wall. capacitor. When the engine began to work, the back of the grate was heated, and then cool.
In modern two.chamber refrigerators, the capacitor tube is located inside the side wall, which leads to its heating. Why is it done? During the operation of the freezer, the minus temperature is created, in the places of the door adjacent to the body, cold air finds the output. If the temperature is high in the room, then condensate can form on the walls, which eventually leads to corrosion and mold on the seal.
The capacitor located behind or on the sides of the pipe allow moisture to evaporate.
So the system works. For what reasons, the walls of the refrigerator (LG brands) are basking too much:
- The room is too hot, bad ventilation. For the normal operation of the refrigerator, the distance between the case and furniture should be 5-7 cm minimum.
- The technique has recently been defrosted. Then it will take time to cool and the temperature resumes. The same thing happens after loading in the department of warm products.
- The silicone (rubber) seal in the freezer is heated, which makes the door fit tightly to the body. As a result, cold air does not leak to cool the walls.
In some refrigerators (Nord, Indesit), a partition between the refrigerator and freezers is heated. This is a normal phenomenon, because moisture is most often formed here. It is recommended to take care of the side walls of technology, if they are always dry, then the breakdown does not threaten you.
The refrigerator condenser is heated
With normal operation, the temperature of the grille should not exceed 45 degrees. If the capacitor is too hot, then check:
- The presence of dust and oil praises. Dirt makes it difficult to heat, so the grate must be kept clean. Disconnect the equipment, push the body from the wall and clean the capacitor from dust.

The leakage of the cooling gas is also likely. But only the master will be able to detect the problem in diagnosis.
Why is the partition between the refrigerator and the freezer heats up
In some cases, the refrigerator begins to heat up not only on the sides, but also inside. The temperature of the partition separating the main compartment and the freezer rises. This is due to the fact that the condenser tubes are usually present inside it.
Normally, they prevent a refrigerator breakdown due to moisture on its inner walls and door. If the partition with the tubes inside heels moderately, you do not need to worry about this. But if the temperature rises too much, you need to contact the service.
What to do if the freezer heats up a lot
If the freezer is hot outside, then in some cases the problem can be eliminated independently. The home repair algorithm looks like this:
- First of all, it is necessary to inspect the freezer door and make sure that when closing it, the seal adjacent to the case. If the elastic band is clogged and has become stiff, wash it with soap solution and treat it with hot water. A strongly worn seal is simply changed to a new.
- Products are removed from the freezer, turn off the unit and defrost the ice accumulated on the walls. A strong “fur coat” inside the device prevents normal heat transfer.
- If the unit does not stop heating hard, you need to check the position of the thermostat. You can not constantly keep the freezer in super.commercial mode, the function is included only if necessary.
- If the refrigerator stands close to the wall, you need to move it away. At the same time, the rear surface of the aggregate body is inspected. if there is a strongly dusty grille there, you need to clean it.
If simple measures did not help, and the hot side walls of the freezer do not cool down, you should consult a specialists. The problem may consist in the wear of the internal details of the unit or a freon leak. It is impossible to repair at home in this case without appropriate skills.
Attention! In the summer, the freezer can overheat due to exposure to direct sunlight. In hot weather, the refrigerator is best rearranged in a shaded angle.
The refrigerator is not recommended to be placed close to the heating battery or kitchen slab
What to do
Depending on the cause and place of heating, the solution methods differ:
- If the lateral parts become hot, the reason may be compressor damage. It will have to be replaced. This is also due to the fact that too many foods or hot dishes are loading into cameras. They can heat up because the refrigerator door opens very often. If you do not make such errors, the problem may be solved.
- When the back wall is too warm, it is worth checking if the grate is not contaminated. Outside, it is worth cleaning it, turning off the device. It is important not to damage the capacitor. If this did not give a result, you need to check if the temperature sensor itself is good for the condenser.
- With constant heating of the capacitor, the problem is often a malfunction of the heat exchanger or temperature sensor will have to be replaced. Sometimes there is enough complete defrosting and proper use of the device.
- In order to avoid strong heating, the partition should be engaged in repairing the heater or replacing the seal, if it does not fit tightly enough.
So that the device does not bite, it is important to control so that the doors are closed tightly. In no case should you leave them open for a long time. It is not recommended to put hot food in chambers: this becomes the cause of many breakdowns.
If the problem does not disappear with the correct use of the refrigerator, then it is associated with a breakdown of one of the mechanisms of the device. In this case, diagnostics and repair are required.
The refrigerator in the partition between the cameras is heated
At the time of turning on the motor, a small heating of the partition between the freezer and refrigerator chambers occurs. This part heats up to avoid the formation of condensate and its further drainage along the internal walls. But often they call the service center with the question: should the partition be heated so that it is difficult to hold your hand? No, if the device is very hot between the cameras, this indicates a malfunction of the valve or depressurization of the circulation system.
If you have determined that the specific part of the housing of household appliances is heated, you need to find out if it should be heated in working condition. If the answer is negative, you do not need to think for a long time what to do. It is enough to call a refrigerator repair master who will diagnose. The specialist will find a breakdown and indicate possible options for eliminating equipment malfunctions.

Why is the freezer heated?
The heat in refrigerator and freezer equipment is assigned using a condenser-an exchanger located on the back of the case-this part can be visible or sewn up with an additional sheet of metal. In some modern models, the capacitor is even in the lateral part of the case. When the engine is included in the work, distilling the Freon (refrigerant) system, the heat exchanger grille heats up, and the temperature in this place can be quite high. The engine operates from 20 to 25 minutes in the standard mode, after which it is off the same or more period of time. Due to the fact that the heat is “pumped” during the launch of the motor, in those models of equipment where the heat exchanger grilles are on the sides, the walls can significantly heat up.
Another reason that the camera from outside is warming is the influence of an external heat source. If the device is installed nearby with a gas stove, an electric oven or a heating radiator, this is just such a case. Avoid such an undesirable neighborhood, especially if the devices are in close proximity to heat exchangers. What threatens such a location of household appliances? Constant external heating will worsen the heat transfer, so the compressor can overheat, and the breakdown of the most expensive unit of the device is extremely undesirable from reasonable reasons.
Speaking about independent freezers, we note that their causes of heating are similar to refrigerators with 2 cameras. But in freezers, the difference between T ° indicators inside and from the outside of the device is higher, therefore the heating of the walls will be more pronounced.
If, reading the instructions for the electrical appliance, you found out that heat exchangers are located on the sides, mounting the device, leave a gap at least 2-3 cm between these walls and other surfaces to ensure normal air circulation and, accordingly, cooling the surfaces.
Noticed that the walls of the refrigerator or dangling are warming up all the time and t ° the surfaces is so high that even the palm can hardly be held on the surface? So this is a good reason to call the master.
We list some causes of excessive walls that do not indicate a failure and do not require intervention by the user or master:
- Defrosting was recently carried out. The first hours of operation of the motor will “catch up” the cold, so the walls will overheat. To facilitate the operation of the device, do not load the products into the chambers immediately after defrosting. let the device work for at least 1 hour.
- Large of a large batch of products. It is difficult for a motor to produce a sufficient amount of cold to quickly cool the impressive volume of products, so try to load them in batches.
- Used to send not cooled dishes to the shelves? So, warm walls. normal in this case. Another question is that this is not recommended for this.
- When the Options Option is turned on.
- Check the freezer. if the block of ice inside has accumulated? Abundant ice can prevent normal heat transfer. Defrost the device for at least 24 hours.
- The door can also cause, especially if it is often opened and closed. Analyze your actions in the kitchen and make a plan in your mind. you may be able to reduce the number of door opening at times with the proper organization of cooking processes. LOW CLOTHING is another reason, so check using a sheet of paper the density of the door of the door seal to the body.
- Setting a temperature regulator for a maximum mark. For most regions, this is an extreme measure, and the summer sultry months are not a reason to turn the thermostat all the way.
What to do if it is hot between the refrigerator and the freezer?
No matter how high.quality the rubber seal on the doors, through it, cold leaks can still occur. If the difference T ° will be essential, then corrosion may begin, mold appears, the elastic band will freeze, and t. P. To prevent this from happening, manufacturers along the perimeter of the freezer also pave the capacitor tubes that have the property to bask during operation. and often they are located in the intercom partition. Like cases described above, this is not a problem and should not cause user concern.
Sometimes in some models of the equipment of the Atlant brand between the cameras are installed tape heaters attached to the inside, therefore, heating the interval between the compartments in this case is inevitable, but this is just a measure of protection from the appearance of condensate.
Why is the freezer hot, what to do
You felt that the walls of the freezer are hot? This is possible while the compressor continues to work. But when the motor is resting, the walls should cool down. If this does not happen, you need to look for the reasons why the freezer is warming.
Initially, the design of the refrigerator provided for the placement of the freezer at the top. In modern models, it is located below. This is a more rational approach, since the compressor first pumps the cold into the freezer, and then in the refrigerator.
Since its task is to cool the products, it seems that its walls should also be cold. However, it is not. To better figure out why they heat up, you need to understand the general principle of work.
Thanks to the compressor, the refrigerant circulates through the system, absorbs heat and thereby cools the chambers. The accumulated heat is excreted through the grill, which was previously located on the back wall.
Now these tubes are inside the case, on the sides and from above. Therefore, do not be surprised that it becomes hot between the refrigerator and the freezer.
about how the refrigerator works. Read in a separate article.
If the walls are heated slightly and cool during the “rest” of the motor. then do not worry. The instructions indicate the climatic class of technology: at what temperature it should be operated.
But if the camera heats up constantly and the temperature clearly exceeds the norm. this indicates the problem that has arisen.
Diagnostics and repair
Listen, the compressor is turned off or it works without stopping? If the operating time is exceeded, this indicates a problem. Therefore, the walls are heated and do not have time to cool.
What could become an indirect cause of continuous work?
The department door is often open for a long time
The gap could also form in the sealant, and warm air penetrates inside. The temperature rises, the sensor reports this to the main module. Therefore, the latter does not give a command to turn off the motor until the necessary values are reached.
- Read the instructions again. Do not open the door for a long time.
- Inspect the rubber seal. If he has worn out, replace. If you clog, wash with a warm solution of water and soap. With deformation, return the shape to the rubber will help with hot water.
Irregular thermoregulator values or mode
With the “Super.Summer” mode set in mechanical models, the freezer will cool “until you drop” until you disconnect it. Check, maybe you accidentally set this mode.
Too low thermoregulator values lead to similar problems. Correct.
According to the rules, the case should stand at a distance of 5-7 cm from the walls, away from batteries and furnaces. If there is too little space for normal ventilation, the walls can overheat.
You loaded a lot of products at once into the department? Then the motor will work until the temperature recovers. Normally, this should take no more than 20-30 minutes.
If the freezer grows in the freezer with No Frost, this indicates a malfunction. Heat transfer is violated, the compressor works with double load, the walls of the freezer heat up.
What breakdowns are given in the continuous operation of the motor and require repair?
The thermostat broke
When the thermostat breaks, the module cannot get the temperature data in the department, so it does not send a signal to the motor for disconnecting. You can replace the thermostat yourself. Most often it is located inside the camera on the side wall (with a separate adjustment).
The problems of the evaporator
The breakdown of any element of the evaporator threatens the failure of the entire refrigerator. It is necessary to diagnose a timer of the thaw, sensor, heater. In such cases, it is better to contact the master, because you need special equipment. He will remove the back wall and replace broken parts.
This is a refrigerant that circulates according to the system. A leak may occur for such reasons:
- Corrosion of the steel circuit. A refrigerant moves along the contour of the contour, and the slightest damage during corrosion leads to a leak.
- During defrosting, you used physical strength and damaged the camera, perhaps pierced the body. Read more about this on the page “What to do if you pierced the freezer or evaporator”.
You need to contact the service center for localizing damage and refueling the system by freon.
Occasionally the problem may be in the management board. When the moisture was closed or moisture, the simistor could burn on it, which controls the compressor. You need to call all the elements and eliminate the breakdown.
Noticed that the walls of the freezer are heated? Do not panic, check these elements, and then call a specialist.
The compressor or wall of the refrigerator is heated
If you have a modern refrigerator, then, most likely, the capacitor is on the side, under the metal wall: so it is heated. And there is absolutely nothing to worry about here: this is exactly what the refrigerator works. heat climbs in the chamber and is given out when passing through the capacitor tubes. When the compressor is idle, the walls cool down.
Why is the refrigerator in the back heat
The older refrigerators have an extensive network of the condenser tubes, as a rule, is located behind, and it is not covered by anything. If they are heated within about 45 degrees, you should not worry: this is a normal workflow. Just do not forget to clean the condenser tubes of dirt and dust at least once a year, which inevitably sticks on them and worsening heat transfer.
The perimeter of the freezer door is heated
So it should be: this is done so that the ice does not intend to the oxide elastic band of the camera.
If you notice that, for example, an electronic scoreboard is heated, then the reason, most likely, overheating of the contacts. This and such problems require the intervention of a qualified specialist.
Suspiciously strong heating
When the heating of the walls or partitions in the refrigerator becomes suspiciously strong, we advise you to start a simple diagnosis on your own to begin with.
- Make sure that the refrigerator is installed at a sufficient distance from the walls of the room and furniture for normal heat transfer: at least 5-7 cm is recommended.
- Check that there are no household appliances that release a lot of heat nearby: electric stoves, ovens, heating batteries.
- Do not allow direct sunlight to fall on the refrigerator.
- For one reason or another, there is too warm in the room, and the unit has to work more intense for cooling.
- Dust and dirt were praised on the capacitor tubes, which worsened their heat transfer.
- The “Super-Summary” mode is included, which is why the entire system begins to work more intense and, therefore, basking.
- The refrigerator will be harder to heat up when the first turning on or after defrosting: it needs to cool the cameras to a given level quickly.
The refrigerator heats up a lot
To begin with, the rear wall of the refrigerator is always heated, and this is not a defect. on the contrary, it indicates the normal operation of the unit. The refrigerator cools the products inside, the evaporator on the inside of the wall cools it from the inside, and heats it outside. There is a capacitor.
But should the refrigerator heat up enough?
If the refrigerator warms up between the cameras, this is an occasion for anxiety.
Any malfunction of refrigerators must be eliminated immediately, and not delay the repair until better times. It will not be better, and the breakdown can be even more serious. If any malfunctions are detected-do not pull, contact the service.
What are the reasons for overheating of your refrigerator can be found:
- Damage to the thermostat. The faulty thermostat does not turn off the motor at the right time, and it works further above the norm, heating the unit stronger than the necessary. It will be necessary to replace the thermostat with a new.
- Dust accumulation can disable the unit, so it must be regularly removed. By the way, it accumulates in the compressor compartment.
- Incorrect installation of the refrigerator. The installation of other working devices, to batteries is considered incorrect. The distance between the rear wall of the refrigerator and the wall should be at least 6-10 cm. Otherwise, the unit overheats, since the air from the back wall of the refrigerator does not circulate properly. Move it away from the walls/large appliances/furniture and observe whether the case will heat up.
- Raising the load (clogged with bit). When filling out the refrigerating chamber, you need to remember the basic rules, and even more so do not put the unheated pots, pans. In this case, the temperature in the chamber is disturbed, and the motor was shaking with a vengeance to restore the necessary temperature regime. Thus, the capacitor warms up. and soon a serious repair will be required, as this is fraught with serious breakdowns of the motor.
If we talk about heating the side wall, then in modern advanced refrigerators this is the norm, because the capacitor is installed along the side wall, and not on the rear, as it was with older models.
What to do if the refrigerator warms on the sides?
First it is worth checking the temperature. if your refrigerator has a display, this will not be difficult. Also check the rubber seal on the door, it could be thinned during use, and thereby passes warm air inside the chamber.
Next, you need to check for the presence of dust, as well as measure the distance between the refrigerator and the wall.
Why does the refrigerator warm up on the sides
Noticing that the housing is heated at the refrigerator, do not immediately worry. This usually happens for natural reasons, but can be caused by improper operation and breakdown. Therefore, you should first figure out why the refrigerator is heated by the side walls and other parts of the case, and if necessary, contact the service center.
To understand why the refrigerator housing is heated, we will figure it out in the principle of its work. Refrigeration equipment operates in cyclic mode. In the process of turning on and off the compressor through the cooling system, the freon circulates. Changing his physical properties, he derives the heat that accumulates inside the cameras, out. The return of thermal energy occurs through the capacitor. This is a radiator grille, which in old models of equipment is located outside, on the back wall. In modern models, it is hidden inside the case.
Reference. The capacitor is mounted in the side walls not only to improve the appearance. It contributes to the evaporation of moisture and prevents the appearance of condensate, which is formed due to the difference in temperature in the chambers and room.
The outer walls of the refrigerator are heated
When the capacitor is heated, the external side walls of the aggregate are heated. The temperature of the case rises within 20-25 minutes, while the working cycle of the compressor lasts. Then it is gradually reduced to normal values, since the engine is disconnected. If the compressor works intensively and for a long time, the heating temperature increases. This is a standard situation in which both a new refrigerator and a long.operated one is heated on the sides. In obsolete models there is a hot rear refrigerator wall. In this case, do not worry.
For the same reason, the walls of an independent freezer are warming up. But since the difference between the temperature inside the unit and outside is greater than that of refrigerators, they have more pronounced.
Advice. To ensure normal air circulation, it is recommended to leave the gap between the side walls of the device and other surfaces of at least 2-3 cm.
The partition between the cameras is heated
Why is the refrigerator warming between the cameras? Even high.quality rubber seal passes cold air from the chamber. In the case of a large difference in temperature between the external and internal medium, condensate forms, corrosion begins, mold appears, the elastic band is frozen. To avoid this, manufacturers of refrigeration equipment lay the condenser tubes around the perimeter of the freezer. This leads to the fact that the refrigerator warms up between the refrigerator and freezers. This situation should not be an concern for anxiety.
Reference. To protect the device from the appearance of condensate, some models of the Atlant brand are supplied with tape heaters between the compartments. In this case, the heating of the partition is inevitable.
Why the walls of the refrigerator are constantly hot
If the case is constantly hot, the unit works at full power and does not have time to cool down. This happens in good and faulty refrigerators. There are several reasons that do not relate to the failures of technology:
- After defrosting or the first inclusion of a new device, it gains the required temperature within 1-3 hours and does not turn off. In order for this process to go faster, it is recommended not to load the products into the camera, but to let the technique work idle.
- When setting the “Fast Froth” mode, the compressor works at full force.
- If the temperature controller is set to the maximum indicator, the motor works non.stop. It is not recommended to do this, the installation of the regulator on average values is considered optimal.
- It is hot in the room. At a temperature of 30 ° C and above, heat transfer is difficult, the load on the compressor increases.
- The refrigerator is installed next to the heat source (kitchen stove, heating radiator, etc. P.). External heating worsens heat transfer and gives overheating the motor.
- Household appliance is pulled close to the wall, which is why it heats up. If the radiator grille is located on the rear wall of the equipment, there should be a gap of at least 7 cm between it and the wall.
- If a large batch of products is loaded at the same time, the compressor tries to cool it to the set temperature and does not turn off for a long time. To avoid this, the refrigerator is filled in small batches.
- When hot or unheated dishes are placed in the device, the motor tries to catch the cold and works for a long time.
- Normal heat transfer is disturbed when metal, glass or ceramic containers lean against the walls of the device.
- The reason may be the frequent and long opening of the refrigerator door. To cool the warm air entering the chamber, the motor works more intense.
- If the unit has not been defrosting for a long time, and an ice has formed in it, which prevents normal heat transfer, the compressor works at full force. To correct the situation, the device is defrosting.
- Когда загрязнена решетка в моделях старого образца, расположенная сзади, это препятствует теплообмену. As a result, the case overheats to high temperatures. The grille must be periodically cleaned of accumulated dirt.
These causes are non.critical and easily eliminated on their own. To avoid them, follow the rules for the operation of household appliances.
In what cases it is worth calling the master
If the body of the equipment is constantly heated, first check the refrigerator settings. Then they pay attention to compliance with the rules of operation of the device and eliminate all the shortcomings. If this did not give a result, they turn to the search for technical problems. First of all, the rubber seal is checked. To search for other malfunctions, it is better to invite a specialist who will diagnose and eliminate problems. Independent repair can lead to more serious breakdowns.
Advice. Before the arrival of the master, turn off the refrigerator from the electric network, remove the products and defrost the unit.
