Owners of brand refrigeration equipment Polyus is often faced with the need to manually control defrost cycles, especially in models where this process is not fully automated or requires periodic user intervention to maintain optimal performance. Understanding how to correctly activate defrost modeis critical to prevent the formation of an ice crust on the evaporator, which over time can lead to compressor overload and increased energy consumption.
Modern and classic Polus models may have different control panel designs, where the defrost button may be separate both a physical element and part of an electronic menu. In this article we will analyze in detail the algorithms of action for various modifications, explain the difference between automatic drip system and forced defrosting, and also consider typical errors during operation.
Before you start activating any functions, you need to accurately determine the type of your cooling system, since the very principle of interaction with technology. If your unit has one defrost buttonit is usually located on the front panel or inside the refrigerator compartment.
Identification of the defrost system and location of controls
The first step in the process of setting up or forcing a defrost is to determine the type of defrost installed in your refrigerator system. Models of the Polyus brand can be equipped with both classic static system (Direct Cool), which requires periodic manual defrosting, and more modern options with the function No Frost or "Crying Evaporator", where the process occurs automatically, but may require manual start in case of icing.
A visual inspection of the control panel will help you understand which interface you are dealing with. In most cases, the controls are located on the top of the cabinet or on the inside wall of the refrigerator compartment. If you see a physical button with an icon of a snowflake or a drop, we are talking about direct access to the function.
It is important to note that in some modifications the button can perform a double function: a short press changes the temperature mode, and a long hold activates defrost cycle. Be careful when manipulating so as not to accidentally reset the main cooling settings.
⚠️ Attention: Never try to force defrost if there is no visible frost or ice in the chamber. Frequent defrosting cycles unnecessarily lead to an increase in the temperature inside the chambers and can negatively affect the safety of products.
Electronic models may not have a dedicated button, but require entering the service menu or holding down a key combination. In such cases, the key element becomes control display, which displays the current operating status of the unit.
Algorithm for turning on forced defrosting
If your Polus refrigerator model involves manual or semi-automatic control of the defrosting process, the activation procedure usually follows standard protocol. Before you begin, make sure that the device is connected to the network and is in working condition, however, the compressor may not be working at the moment.
To start the process, you need to find the appropriate control element. On models with a mechanical regulator, this may be a rotary switch that must be moved to the “Defrost” or “0” position. In electronic versions, the algorithm of actions looks different and requires accuracy.
☑️ Check before starting defrosting
The standard sequence of actions for electronic panels often involves long pressing the button. Press the defrost control button and hold it for 3-5 seconds until a sound signal appears or the indication on the display changes. This action sends a signal to control controller about the need to start the evaporator heating element.
After activating the mode, the refrigerator may emit a characteristic click, indicating the relay is switching. At this moment, the compressor stops and the evaporator begins to heat up. The duration of this process depends on the amount of frozen ice and the power of the heating element.
What happens inside when you press the button?
When the defrost mode is activated, the controller turns off the compressor and fan (if any), supplying voltage to the heating element (heater), located behind the rear wall of the freezer. The ice melts, the water flows into the drainage tray, and after the cycle is completed (usually 20-40 minutes), the system automatically returns to the cooling mode.
Some users prefer to completely turn off the device for natural defrosting, but using the standard function allows you to do this faster and more efficiently, since heating element works specifically on the evaporator.
Features of the button operation in different series of Polyus refrigerators
The diversity of the Polus model range determines the availability of various engineering solutions in control systems. In older series, such as classic two-chamber models, the defrost button is often a mechanical switch integrated into the thermostat.
In newer series with electronic control, the functionality of the button can be expanded. For example, double pressing can activate a mode "Super defrost"that increases the operating time of the heater to remove thick ice crust. This is especially true for regions with high air humidity.
It is also worth mentioning models where the defrost button is combined with an emergency temperature indicator. In such cases, a flashing indicator may indicate the need for a defrost procedure, even if you did not manually press the button. This is a smart self-diagnosis system that analyzes the operation of temperature sensors and time.
Owners of models with a display should pay attention to the symbols. Often the activation of a feature is indicated by a flashing snowflake or raindrop icon. If after pressing the button the indication does not change, there may be a failure in the system or the device needs to be rebooted.
Frequency of the procedure and system maintenance
The question of how often you need to turn on defrosting remains one of the most pressing. For models with manual or semi-automatic control, the optimal frequency is considered once every 3-6 months, however, this parameter greatly depends on operating conditions.
If you notice that the layer of frost on the back wall of the freezer exceeds 5-7 mm, this is a direct signal to action. Ignoring this fact leads to the fact that the ice begins to work as a heat insulator, forcing compressor to work for wear, trying to maintain the set temperature.
| Influence factor | Recommended frequency | Impact on operation |
|---|---|---|
| High humidity in the room | Once every 2-3 months | Accelerated ice formation |
| Frequent opening of doors | Once every 3 months | Intake of moist air |
| Dense filling of chambers | Once every 4-5 months | Impaired air circulation |
| Normal conditions | Once every 6 months | Standard operating mode |
Regular maintenance also includes checking the condition of door seals. If the rubber is worn out and does not fit tightly, warm air constantly enters the chamber, which drastically increases the frequency of necessary defrosts. In this case, the defrost button will be used too often, which is not good for the resource of the heating element.
Typical problems and methods for eliminating them
Despite the reliability of the Polyus technology, users may encounter situations where the defrost button does not respond or the process does not proceed correctly. One common problem is the button sticking due to moisture or condensation getting inside the control panel.
If the button does not press or is difficult to press, do not use excessive force to avoid damaging the switch mechanism. First of all, try gently drying the area around the button with a hairdryer at the minimum temperature or simply letting the appliance dry after unplugging it.
⚠️ Attention: If, after turning on the defrost mode, you smell a burning smell or see sparking, immediately unplug the refrigerator from the power supply. This may indicate a short circuit in the heating element circuit.
Another possible problem is the absence of a relay clicking sound when the function is activated. This may indicate a malfunction of the relay itself or the control unit. In such cases, defrosting will have to be carried out using the classic method: completely disconnecting from the network for 12–24 hours.
It is also worth considering that in some modifications, after defrosting, you need to manually restart the cooling cycle if the automation did not work. To do this, you may need to turn the temperature control to the “Off” position and then turn it back on.
Tips for care and extending service life
Proper operation of the Polyus refrigerator allows you to minimize the need for frequent manual defrosting and prolongs the life of the entire unit. Always make sure that food does not come close to the back wall where the evaporator is located. Using airtight containers instead of open pans significantly reduces the humidity inside the chambers. Less moisture in the air means less ice on the walls, which means you will have to use the forced defrost function less often. evaporator.

Regularly check the drainage hole for blockages. If the water from the melting ice does not have time to leave, it will freeze at the bottom of the chamber, forming an ice plug, which is difficult to remove without completely defrosting and disconnecting the drainage tube.
How to clean the drainage?
Use a soft wire or a special brush, carefully inserting it into the drainage hole. You can also pour a little warm (not boiling water!) water into it to dissolve the fatty film.
Following these simple recommendations will help maintain the efficiency of your refrigerator at a high level and ensure the safety of food in any conditions.
Is it possible to speed up the defrosting process with a hair dryer?
Using a hair dryer is possible, but requires extreme caution. Direct the warm air stream only at the ice, avoiding hot air hitting plastic parts and seals, which can become deformed due to high temperature. Do not use a hairdryer if there is water inside the chamber.
Why does the refrigerator take a long time to reach the temperature after defrosting?
This is normal. After the defrost cycle, the walls and food became warm. The compressor takes time (from 2 to 6 hours) to cool the entire volume of the chamber to the specified parameters. Do not load the chamber with food until the temperature has stabilized.
What to do if the defrost button lights up but does not go out?
If the indicator is constantly on, this may mean that the cycle is completed, but the system has not detected the end of the process, or a failure has occurred in the control module. Try unplugging the refrigerator for 15 minutes to reboot the system.
Do you need to remove food when using the defrost button?
With short-term forced defrosting through the button (15-20 minutes), the temperature in the main chamber drops slightly, so the food can be left. However, for deep defrosting of the freezer, it is better to transfer the food to a cool place.
