Refrigeration equipment of the brand Biryusa is deservedly popular due to its reliability and availability, but over time, owners may encounter the problem of insufficient cooling of products. The situation when the temperature in the main chamber ceases to meet the standards, and the ice melts in the freezer, requires immediate intervention. Before calling a technician or thinking about buying new equipment, it is worth carrying out independent diagnostics, since often the reason lies in trivial things that can be easily eliminated.
The efficiency of the compressor and the circulation of freon depend on many factors: from the tightness of the door closure to the technical condition of the thermostat. Ignoring the first signs of deterioration can lead to food spoilage and more serious system failures. In this article, we will look in detail at how to make the refrigerator colder Biryusausing proven methods of setup and maintenance.
Understanding the operating principles of your model will allow you to quickly restore the desired temperature. We will consider both simple adjustment steps and more complex technical nuances that require attention. Timely reaction Changes in the operation of the unit are the key to its long service.
Checking the operating mode and settings of the thermostat
The first step in solving the problem of low temperature is an analysis of the current settings. Often, users accidentally knock down the regulators or do not take into account changing operating conditions, for example, the onset of hot summer or, conversely, severe cold in winter. In refrigerators Biryusa the thermostat can be mechanical (with a rotary knob) or electronic (with a display).
If you have a mechanical model, the knob usually has divisions from 1 to 5 or from "Min" to "Max". To increase the cold, turn the knob towards higher values. However, you should not immediately turn the regulator to maximum, as this will force the compressor to work without stopping, which will lead to its overheating and possible failure. The optimal position for normal operation is considered to be the average value or slightly higher.
- ❄️ Set the regulator to the value "3" or "4" for the standard operating mode.
- 🌡️ In hot weather, a short-term increase in the mode is allowed, but watch out for shutdown cycles.
- 🔌 With electronic control set the temperature in the main chamber to +2...+4°C, and in the freezer -18...-20°C.
- ⏳ After changing the settings, give the refrigerator 4-6 hours to stabilize the temperature.
⚠️ Attention: If, after setting the regulator to maximum cooling, the compressor does not turn off for more than 12 hours, and the temperature does not drop, this indicates a system malfunction, and not an incorrect setting.
It is important to consider that thermostat reacts to the temperature of the evaporator, and not to the air in the chamber. If the sensor is dirty or misaligned, the readings may be incorrect. In some models Biryusa the regulator is located inside the chamber, in others - outside on the body. Make sure that the handle rotates freely and is not stuck in the extreme position.
Diagnostics of seals and chamber tightness
One of the most common causes of loss of cold is a leak in the seal doorway. The rubber seal (cuff) loses elasticity over time, cracks, or simply becomes contaminated with fat and food, causing the door to not fit tightly. Warm air from the room constantly flows inside, causing the unit to work hard, but not achieve the desired performance.
To check the tightness, you can use a simple method with a sheet of paper. Clamp the sheet between the seal and the body around the perimeter of the door. If the paper comes out easily and without resistance, then the seal is broken in that area. Also carefully inspect the rubber for visible tears, dents or peeling from the plastic base of the door.
☑️ Checking the seal
If the seal is simply dirty, it must be thoroughly washed with warm water and a mild detergent and wiped dry. If elasticity is lost, you can try to restore the shape using a hairdryer: gently heat the deformed area and press it against the body until it cools. However, this is a temporary measure, and soon you will need replacement of the seal.
Do not forget to check the door hinges. If they become loose, the door may warp, creating a gap at the bottom or top. Tightening the fasteners often solves the problem of loose closure. In models with the system No Frost leakage also leads to freezing of the water drainage channel and the appearance of puddles inside the chamber.
The influence of location and ventilation on cooling
Correct installation of the refrigerator Biryusa plays a critical role in the efficiency of heat transfer. The condenser (grid at the back or on the sides) must be freely washed by air in order to transfer heat to the room. If the unit is moved close to the wall or is crowded with furniture, the air circulation is disrupted and the compressor works with overload, not having time to cool the chambers.
There are strict recommendations on distances from walls and surrounding objects. The minimum distance to the back wall should be at least 5-7 cm, and on the sides - 3-5 cm. The upper part should also be free, especially if you plan to install a shelf or cabinet on top. Violation of these rules is a common reason why the refrigerator stops freezing in the summer.
| Installation parameter | Minimum value | Recommended value | Consequences of violation |
|---|---|---|---|
| Indentation from the back walls | 5 cm | 7-10 cm | Compressor overheating, increased energy consumption |
| Indentation on the sides | 3 cm | 5 cm | Heating of the side walls, condensation |
| Ventilation from above | 10 cm | 20 cm | Stagnation of hot air |
| Temperature in the room | +10°C | +16...+25°C | Incorrect operation of the thermostat |
In addition, pay attention to the temperature in the room. Refrigerators Biryusa, like most household models, are designed to operate in the range from +10°C to +32°C (climate class N or SN). If the room is too hot (above +32°C), the system may not cope physically. In this case, the only solution is to improve the kitchen ventilation or install an air conditioner.
Rules for loading and placing products
Incorrect loading of chambers is another factor affecting the temperature. Cold air should circulate freely between the products. If the shelves are packed tightly and the vents are blocked by pots or bags, the temperature gauge will read incorrectly and the cold will not be distributed evenly.
It is especially important not to place warm or hot foods inside. This creates a sharp jump in temperature and humidity, which forces the compressor to work in extreme conditions. In models Biryusa with a drip system, this also leads to the formation of excessive ice on the back wall, which then interferes with heat transfer.
- 🥩 Do not fill the chamber to more than 70% of the volume for free air circulation.
- 🍲 It is strictly forbidden to place hot food - let it cool to room temperature.
- 🌬️ Make sure that the food does not block the holes in the ventilation system (usually on the back wall).
- 🧊 In the freezer, leave small gaps between the bags to allow the cold flow to pass through.
It is also worth considering that an empty refrigerator keeps the cold worse than a full one, since food acts as a cold accumulator. However, we are talking about proper loading, and not about filling the camera to capacity. If you store little food, you can put bottles of water in the chambers to stabilize the temperature.
Maintenance: defrosting and cleaning
Even modern systems No Frost require attention, and refrigerators with a drip system (crying wall) need regular defrosting. The build-up of ice on the evaporator creates a heat-insulating crust, due to which the cold stops flowing into the chamber, although the evaporator itself may be icy.
It is recommended to completely defrost the refrigerator Biryusa at least once every 6 months, and with active use - every 3-4 months. To do this, unplug the appliance, remove all food and leave the doors open until the ice has completely melted. It is strictly prohibited to speed up the process of chipping ice with a knife - you can damage the freon tubes.
⚠️ Attention: Never use sharp objects to chip ice. Damage to the evaporator will lead to a refrigerant leak and costly repairs with refilling with freon.
During defrosting, be sure to rinse the internal chambers with a solution of baking soda (1 tablespoon per liter of water) or a special refrigerator cleaner. Cleanliness not only affects hygiene, but also the performance of the sensors. Also check the drainage hole in the back of the main chamber: if it is clogged with crumbs or mucus, the water will not drain, will freeze and turn into an ice plug that interferes with cooling.
How to defrost correctly?
Unplug the refrigerator. Remove all food items and shelves (if they are removable). Leave the doors open for 10-12 hours. Collect water with towels or sponge. Rinse chambers and drainage. Turn on the refrigerator empty for 2 hours, then load the food.
Cooling system malfunctions and when you need a technician
If all of the above measures did not help make it colder, most likely the problem is of a technical nature. In refrigerators Biryusa the most common freon leaks are thermostat failure, compressor failure or capillary tube blockage. It is impossible to fix these faults on your own without special equipment and skills.
If there is a refrigerant leak, the compressor may work continuously, but there will be no cold. A characteristic feature is the absence of characteristic gurgling or hissing during operation, as well as swelling of the side walls (in some models). If you hear the motor humming, clicking, but not starting, or, conversely, running non-stop without producing cold, this is a reason to call a specialist.
Replacing the thermostat is a procedure available to an experienced home craftsman if he has access to the part. However, in modern models Biryusa access to the thermostat is often limited by design. A malfunction of the start relay or the compressor itself requires professional diagnostics.
⚠️ Attention: If you smell burnt wiring or see sparking in the compressor area, immediately unplug the refrigerator and do not try to turn it on again until the technician arrives.
It is also worth remembering that the characteristics of equipment and the availability of spare parts may change. If your model is more than 10-15 years old, repairs may not be cost-effective compared to purchasing a new energy-efficient unit. Always check the cost of spare parts and labor with the residual value of the device.
Frequently asked questions (FAQ)
Why a refrigerator Is turquoise very cold only at the back wall?
This is normal for models with a drip system ("crying wall"). The back wall is an evaporator on which ice freezes. Periodically it melts and flows into the drainage. If food freezes to the wall, move it 2-3 cm.
Is it possible to increase the cold if the room is very hot?
If the room temperature exceeds +32°C (the upper limit of climate class N), the refrigerator may not cope. Only ventilation, air conditioning or installing a fan that directs the air flow to the rear grille of the unit will help.
How often do you need to change the seal on the door?
The service life of the seal is 5-7 years. However, it needs to be changed as it wears out: if it cracks, becomes hard, or no longer holds the paper during testing. Regular washing and lubrication with silicone oil prolongs its life.
What to do if the ice melts in the Biryusa freezer?
Check that the freezer door is closed tightly. If everything is closed tightly, but the ice melts and the food softens, most likely there is a freon leak or the capillary tube is clogged. A call to a technician is required for diagnostics.
Does the amount of food in the refrigerator affect the temperature?
Yes, a full refrigerator holds the temperature better during short-term blackouts or when the door is opened, since the food accumulates cold. However, it will take a lot of time and energy to initially cool a large volume of warm food.
