How to turn off the freezer in the Biryusa refrigerator

Refrigeration equipment of the brand Biryusa is deservedly popular due to its reliability and affordable price, but not all users know that the design of some models allows flexible control of the operating modes of the chambers. A situation often arises when the volume of the freezer becomes excessive, or it is necessary to switch the unit to cooling mode to store a large amount of fresh food without freezing. Owners are wondering whether it is possible to completely turn off the lower or upper compartment while leaving the refrigerator running.

The answer to this question depends on the specific modification and year of manufacture of your device. In old Soviet models and modern versions with mechanical control, the principle of operation may be radically different. Switching off the freezer possibly not in all cases, and an attempt to do this incorrectly can lead to product damage or compressor failure. It is necessary to clearly understand the structure of your unit before making changes to its operation.

In this article we will analyze in detail the technical features of various series of refrigerators, explain the difference between the “fridge only” mode and a complete stop, and also consider alternative solutions for optimizing food storage. You will learn how to correctly interpret the thermostat readings and when you should contact a specialist.

Design features of Biryusa refrigerators

To understand how to control temperature conditions, you must first understand the design of the cooling system. Most models are Biryusa equipped with a single-compressor system, where the cold is distributed between the chambers through common channels or evaporators. In such systems independent shutdown one of the chambers is technically difficult to implement without special equipment or additional valves, which household models are usually not equipped with.

There are two-chamber models with the system No Frost or “Crying evaporator”, where air circulation is forced. In such units, the freezer is an integral part of the cooling cycle. If you try to “turn off” the freezer by blocking the access of cold, you will disrupt the operation of the entire circuit, which will lead to overheating of the compressor or, conversely, to defrosting of the main chamber.

⚠️ Attention: An attempt to independently shut off the capillary tube or air ducts without professional knowledge will lead to depressurization of the system and loss of warranty.

However, some specific models, especially old models or specialized modifications, may have design features that allow you to change the temperature regime. It is important to distinguish between the concepts of “turning off the freezer compressor” (which is impossible in single-compressor models) and “changing the temperature in the chamber.” In most cases, we are talking specifically about temperature control, and not about physical shutdown.

The difference between mechanical and electronic control

Temperature control in refrigerators Biryusa can be carried out in two main ways: through a mechanical thermostat or an electronic control panel. The set of available functions and the ability to fine-tune depend on the type of control. In models with mechanical regulator, which is usually a round knob with numbers from 1 to 7 or from Min to Max, the user influences the operating time of the compressor.

Electronic control, represented by a display on door or inside the chamber, provides more options. Here you can set the exact temperature for each zone if the model supports the function Independent Cooling (independent cooling). In such devices, turning off the freezer compartment can be done programmatically by setting the maximum possible temperature in this compartment, although technically the compressor will continue to work to cool the main chamber.

It is important to note that even the presence of electronic control does not guarantee the ability to completely turn off the freezer compartment. Manufacturers rarely implement the “Vacation Mode” function specifically for the freezer; more often this mode is intended for the main compartment. Therefore, owners should carefully study the instructions for a specific model Biryusa 133, 134, 640 and newer to make sure that the declared functions are available.

Is it possible to completely turn off the freezer

Question about complete turning off the freezer while the refrigerator is running is one of the most common. Unfortunately, for the vast majority of models Biryusa the answer will be negative. The design of single-compressor refrigerators does not provide for the possibility of stopping the circulation of refrigerant in only one of the evaporators without the use of complex and expensive solenoid valves, which are equipped with premium two-compressor models.

If you set the temperature regulator to the “minimum” or “1” position, the compressor will work less often, and the temperature will the freezer compartment will rise, but it will not become positive. Usually in this mode the temperature drops to -6...-8°C, which is not enough for long-term storage of frozen foods, but also not warm enough for storing fresh vegetables or drinks. Food in the freezer will begin to deteriorate, but will not defrost completely, creating a favorable environment for bacteria.

Why can’t you just turn off the air?

In systems with forced air circulation (No Frost), stopping the fan or closing the damper will lead to freezing of the evaporator itself, since the cold will not go into the chamber. This will cause an emergency shutdown or breakdown.

There is an exception for some models with the "Fresh Zone" function or similar names, where the temperature range can be expanded. But even in this case, we are talking about adjustment within negative temperatures. Full shutdown possible only by turning off the entire refrigerator from the network, which turns it into an ordinary cabinet.

The "Vacation" mode and its effect on the operation of the cameras

Many users confuse the possibility of turning off freezer with Vacation Mode. This function is present in some modern models Biryusa with electronic control. Activating this mode puts the main refrigeration chamber into an economical operating mode with a temperature of about +15°C, which prevents the appearance of mold and odor while the owners are not at home.

It is critically important to understand: in the "Vacation" mode The freezer continues to work in normal mode. This is to ensure that frozen food remains preserved while you are away. If your goal is to free up the freezer for other needs or turn it off to save energy, this mode will not suit you.

Using the “Vacation” mode is justified only if you are leaving for a long time and want to leave only the freezer on. An attempt to use this mode to simulate turning off the freezer is erroneous.

Step-by-step instructions for adjusting the temperature

If your goal is not a complete shutdown, but a reduction in the intensity of freezing or a change in temperature, this can be done using standard means. For models with mechanical control, you need to find a thermostat, which is most often located inside the refrigerator compartment or on the outside of the housing. Turning the knob counterclockwise to lower values reduces the cooling capacity.

For electronic models, the algorithm of actions looks different. You will need to press the Mode or Temp button on the control panel. Using the arrow buttons < and >, set the desired value. Remember that the minimum possible temperature in the freezer is usually -6°C or -8°C, below which the system will not allow it to fall to avoid food spoilage.

⚠️ Attention: A sudden change in the thermostat settings (for example, from maximum to minimum) can cause stress on the compressor. Change the parameters smoothly, at intervals of several hours.

After adjustment, be sure to wait until the temperature stabilizes. This process can take from 4 to 12 hours depending on the load of the chambers and the ambient temperature. Only after this can one draw conclusions about the effectiveness of the settings.

Alternative solutions and common mistakes

Users, trying to turn off the freezer, often make mistakes that can cost expensive repairs. One of the common mistakes is sealing the cold air supply holes with tape or foam rubber. In systems No Frost this will lead to the fact that the fan will continue to circulate air, but will not be able to release the cold, which will cause freezing of the evaporator and breakdown of the defrost system.

The other extreme is the installation of powerful heating elements in the freezer to maintain a positive temperature. The use of third-party heating devices inside the refrigerator compartment is strictly prohibited by fire safety rules and operating instructions. This can lead to the melting of plastic parts, fire or short circuit.

If you really need to use the volume of the freezer compartment as an additional refrigerator compartment with a positive temperature, the only safe solution is to purchase a special thermal container or cooler bag, which is placed inside. However, maintaining a stable temperature of +4°C there will be extremely difficult without special automation.

It is also worth mentioning attempts to reflash electronic control units. On the Internet you can find advice on changing the controller firmware to unlock hidden functions. For technology Biryusa this is practically irrelevant and carries a high risk of turning a serviceable device into a pile of metal.

Maintenance when changing modes

Any manipulations with temperature conditions require a more attentive attitude to the maintenance of the unit. If you keep your freezer in the “minimum freeze” mode (about -6°C) for a long time, condensation may form more actively in it, especially if the door is opened frequently. This requires more regular defrosting, even for models with the system No Frost.

It is necessary to regularly check the freezer door seals. When working in non-standard temperature conditions, the load on rubber profiles may increase due to changes in humidity. Loss of tightness will lead to the constant entry of warm air, which will force the compressor to work without interruption, consuming excess electricity.

The condition of the drainage system should also be monitored. Changing temperature flows can affect the rate of condensate removal. If you notice puddles of water under the refrigerator or inside the chamber, this is a signal that the drainage hole requires cleaning.

When you need to contact specialists

If you are faced with a situation where the freezer has stopped freezing on its own, or vice versa, the temperature in it has become too low, and adjusting the thermostat does not help, this indicates a malfunction. Possible reasons: freon leak, thermostat failure, temperature sensor malfunction, or problems with the control module.

In such cases, you should not try to “fix” the refrigerator by completely stopping the freezer. Professional required diagnostics. The wizard will determine whether it is possible to restore factory settings or whether components need to be replaced. Self-repair of cooling systems requires special tools and knowledge.

⚠️ Attention: If you hear unusual sounds (gurgling, clicking) or smell burning when changing temperature settings, immediately unplug the refrigerator and call a technician.

Specialists can also advise regarding the possibility of upgrading your specific model Biryusa. In rare cases, it is possible to install additional equipment, but the economic feasibility of such actions for household appliances is usually questionable compared to purchasing a new, more functional unit.

Is it possible to use the freezer as a regular shelf if you turn off the refrigerator?

If you turn off the refrigerator from sockets, the freezer will turn into a regular cabinet. However, it is not recommended to use it for storing food without refrigeration due to the lack of ventilation, which will lead to the rapid appearance of mold and a musty smell. In addition, plastic parts can be deformed due to sudden temperature changes if you store hot things there.

Why can’t you set the temperature in the Biryusa freezer above -10 degrees?

This limitation is built into the algorithms of the controller or the design of the thermostat. The protection system does not allow the temperature in the freezer compartment to be raised above a certain threshold (usually -6...-10°C) in order to prevent the growth of bacteria in accidentally forgotten frozen products. This is standard protection, not a breakdown.

Does turning off the light in the freezer affect the operation of the main refrigerator?

In most models Biryusa the light bulb in the freezer is either absent or powered from a common circuit. If the freezer light on your model is constantly on and you decide to physically turn it off (break the circuit), this will not affect the operation of the compressor. However, if you mean “turning off the cold,” then, as mentioned above, in single-compressor models this will disrupt the operation of the entire unit.

Is it safe to keep the freezer empty at the minimum temperature?

Keep the freezer empty while running compressor is possible, but ineffective. The empty volume of air heats up faster when the door is opened, causing the compressor to turn on more often. To save energy and maintain temperature stability, it is recommended to fill the free space with plastic bottles of water or special cold accumulators.
