Buying new household appliances always raises a lot of questions, especially when the device begins to behave differently than expected. Owners often encounter a situation where new Kandy refrigerator the side walls begin to heat up intensely immediately after switching on. This phenomenon causes natural concern, because no one wants to receive a defective product on the first day of operation.
However, you should not rush to conclusions about the breakdown. In most cases, heating of external panels is the normal operating mode of modern refrigeration equipment. The design of brand units Candy involves heat removal through the side surfaces, which is part of an effective heat exchange system. Understanding the physical processes occurring inside the compressor and circuit will help you distinguish normal operation from a critical malfunction.
In this article we will analyze in detail the technical features of the operation of refrigerators, point out the permissible temperature ranges and indicate situations when the intervention of a service center is still required. Competent diagnostics at an early stage will avoid unnecessary stress and guarantee a long service life of your equipment.
Physics of the process: where does the heat from the compressor go?
The operating principle of any refrigeration unit, including models Candy, is based on the circulation of refrigerant in a closed circuit. Compressor compresses gaseous freon, turning it into liquid, and a large amount of thermal energy is released. In older models, a black lattice radiator located on the rear wall was used to remove this heat.
Modern manufacturers, striving for aesthetics and compactness, began to build a capacitor directly into the side walls of the case. This is why the outer panels become hot. This process is called condensation, and it indicates that the cooling system is functioning properly, effectively removing heat from the internal chamber to the outside.
The heating temperature may vary depending on the load on the engine and the ambient temperature. At some points on the surface it can reach 50-60 degrees Celsius, which is quite noticeable for the human hand, but is absolutely safe for the plastic elements and insulation of the device.
⚠️ Attention: If the side wall becomes hot to the point where it is impossible to hold your hand on it for more than 2-3 seconds, or the smell of hot wiring appears, immediately unplug the device.
It is important to note that the heating intensity directly depends on the operating mode compressor. In the first hours after switching on, when the refrigerator tries to cool the empty chambers to the specified parameters, the engine operates at maximum power, causing strong heating of the walls.
Break-in period: why the new refrigerator works more intensely
Particular attention should be paid to the first days of operation. Run-in period is the time required to stabilize the operation of all systems of the new unit. At this time, the Kandy refrigerator can work almost without stopping, which leads to a significant increase in the temperature of the side panels.
There are still no products inside the chambers at this time that could accumulate cold, so the temperature sensors record a slow decrease in degrees and do not allow the compressor to go into rest mode. This is a normal situation, described in the technical documentation for most models Candy.
The duration of the break-in period is usually from 6 to 24 hours. During this time, the unit should reach the required temperature, after which the compressor will begin to turn off, and the heating of the walls will become less pronounced or stop altogether until the next switching cycle.
If after a day of continuous operation the refrigerator does not turn off, and the sides remain hot, it is worth checking the thermostat settings. Perhaps an extremely low temperature has been selected, which forces the equipment to work in enhanced mode.
The influence of external temperature and installation conditions
The environment plays a critical role in heat transfer. If your new Kandy refrigerator is installed in a kitchen where the air temperature exceeds 25-28 degrees, the efficiency of heat removal through the side walls drops sharply. The compressor has to work longer and harder to compensate for the high external temperature.
In addition, ventilation conditions are important. Warm air should circulate freely around the housing. If the unit is pressed tightly against the wall or furniture, or the side gaps are less than 5-7 centimeters, a “heat bag” is formed. The heated air does not escape, but heats the walls even more, creating the effect of a false overload.
Direct sunlight hitting the side surface also contributes. A wall heated by the sun gives off internal heat worse, which forces the cooling system to work under overload. In summer, this can cause constant heating of the case.
The humidity of the room should also be taken into account. In very humid conditions, condensation may appear in cold areas of the condenser (if they are not heated evenly), which is sometimes mistaken for a leak, although this is part of the heat exchange process.
Diagnostics: normal or malfunction of the cooling system
How to distinguish normal heating from a breakdown? There are a number of signs that indicate that something is wrong with your Candy e. First of all, pay attention to the uniformity of heating. During normal operation, a significant portion of the side panel heats up, usually in the area of the condenser circuit.
If you observe local overheating at one specific point, especially in the area of electrical connections or near the compressor itself, this may indicate a poor contact or a faulty start relay. Also an alarming signal is the situation when the sides are hot, but inside the refrigerator the temperature does not drop below 10-12 degrees.
Check the operation of the fan (if the NoFrost model). If the fan does not spin, heat is not removed from the condenser effectively, causing overheating of the outer walls and the risk of compressor failure.
☑️ Symptoms of normal operation
Another important criterion is cyclical operation. A working refrigerator should turn off after initial cooling. If the unit hums for days without a break, even when it’s already cold inside, this is a cause for concern.
Table of temperature conditions and conditions
To simplify diagnostics, we suggest that you familiarize yourself with the comparative table, which will help classify the condition of your equipment.
| Surface condition | Temperature range | Compressor operating mode | Verdict |
|---|---|---|---|
| Warm / Hot | 40°C - 60°C | Cyclic (on/off) | Normal |
| Very hot | 60°C - 70°C | Continuous operation (first day) | Normal (break-in period) |
| Hot | Above 75°C | Continuous operation | Diagnostics required |
| Local heating | Different | Any | Possible malfunction postings |
This table is for reference only. The exact technical specifications of your model Candy can always be found in the official user manual.
⚠️ Attention: Specifications and permissible temperature ranges may vary depending on the specific series of the refrigerator. Always check the product data sheet supplied with the kit.
Common mistakes when installing new equipment
Often the cause of excessive heating is errors made by users during installation. The most common of them is ignoring transportation bolts and fasteners. If the compressor has not been secured or, conversely, the restrictors have not been removed, this can cause vibration and overheating.
It is also critically important to allow the refrigerator to “settle” after delivery. If the unit was transported lying down, oil from the compressor could flow into the cooling circuit. Turning on such a refrigerator without settling (at least 4-8 hours, preferably a day) will lead to the engine running “dry” or with oil in the system, which will cause overheating and a potential wedge.
Why can’t you turn on the refrigerator immediately after transportation?
During transportation, especially in a horizontal position, compressor oil can flow into the circuit tubes. If you turn on the unit immediately, oil will enter the system where it should not be, which will lead to clogging of the capillary tube and overload of the compressor. Let the equipment stand upright for at least 4-8 hours so that the oil flows back into the engine crankcase.
Wrong choice of installation location is another common reason. Installation next to (battery, oven, stove) forces the refrigerator to work in extreme conditions, constantly compensating for external heat.
When you need to call a specialist
Despite the fact that heating is often the norm, there are situations when you cannot do without a specialist. If, after 24-48 hours of operation, the refrigerator continues to operate without interruption, without cooling the food to the required temperature, this is a sign of a freon leak or a clogged system.
The appearance of buzzing, knocking or clicking noises accompanying heating is also a reason to contact service. These sounds may indicate wear on the compressor bearings or problems with the fan.
If you notice that the rubber door seal begins to melt or deform from the heat of the side wall, this indicates critical overheating, which can lead to depressurization of the chamber.
Remember that opening the case yourself or attempting to refill the refrigerator may lead to permanent loss of warranty. The new Kandy refrigerator is a complex device that requires a professional approach when diagnosing serious faults.
Frequently asked questions (FAQ)
How long can the new Kandy refrigerator work without stopping?
During the primary cooling period (the first 6-12 hours), the refrigerator can operate continuously. After the temperature has risen, rest cycles should begin. If the compressor does not turn off for more than 24 hours, this is a reason to check.
Is it normal for the side panel to be hotter than the rear grille?
Yes, this is normal for modern models. In them, the condenser (radiator) is built into the side walls of the case, so they give off the main heat, while the back wall can remain cold or warm.
Can heating cause high temperatures inside the chambers?
Heating the walls itself is not the cause of high temperatures inside, this is a consequence of the operation of the compressor. However, if the refrigerator overheats due to poor ventilation, it may stop cooling food effectively.
What to do if the refrigerator only heats up on one side?
Partial heating may be due to the specific circuit layout in a particular model. However, if one side is hot and the other icy, or the heating is localized at one point, it is worth calling a technician for diagnostics.
