Two-chamber models Biryusa are deservedly popular due to their reliability and availability, but sometimes owners are faced with a non-standard task. There is a need to temporarily or permanently turn off the freezerleaving the refrigeration compartment in working condition. This may be required to save energy, defrost, or if the freezer is out of order, but the main department is still functioning properly.
It is worth immediately noting that the design of most household refrigerators does not provide for complete electronic shutdown of one chamber without affecting the other, if any about older models with one compressor. In such systems, the refrigerant circulates through both circuits, and stopping the compressor will stop cooling in its entirety. However, there are technical techniques and settings that allow you to minimize the operation of the freezer or stop it during maintenance.
In this article we will analyze in detail the physical and software methods for solving this problem, consider the features of thermostats and warn about possible risks for the compressor. It is important to understand the structure of your model so as not to damage the unit in an attempt to save money or carry out maintenance.
Design features of Biryusa two-chamber models
Before you begin any manipulations, you need to understand the type of cooling system of your device. Refrigerators Biryusa are most often equipped single-compressor system with drip defrosting or a No Frost system. In the first case, the evaporator is located in the freezer, and cold air is distributed by natural convection or using a fan.
If you have a model with one motor-compressor, then it is physically impossible to start the refrigeration cycle only for the upper compartment. The refrigerant passes through the freezer, where it boils and takes away heat, and then enters the main compartment. Therefore, you can “turn off” the freezer only conditionally - by ceasing to produce cold or by blocking the air supply.
There are more modern models with Full No Frost system two circuits, but in the budget segment Biryusa they are rare. In such devices, the control can be more flexible, but the principle of operation of the compressor remains the same for the entire volume.
⚠️ Attention: An attempt to mechanically shut off the freon tubes without professional equipment will lead to depressurization of the system and the refrigerator coming out of service. building. All methods described below are safe and do not require disruption of the circuit.
Understanding exactly how cold circulates in your particular specimen will help you choose the right method of exposure. You should not rely on general advice if you have a technical passport with a specific diagram in your hands.
Using a thermostat to stop the freezer
The most common and safest way to affect the operation of the freezer in older models is to manipulate the thermostat. The mechanical temperature control is usually located inside the refrigerator compartment or on the front panel. Turning the knob to the minimum position (usually indicated by the number 1 or Min) reduces the intensity of the compressor.
However, if you unscrew the knob to the "0" or "Off" position, the compressor will stop completely and heat will begin to flow into all chambers. The trick is to find the “golden mean” when the main compartment still maintains the temperature, but the freezer stops freezing. This is relevant if the freezer Biryusa is overcrowded or requires defrosting without turning off the products in the main compartment.
In some models, the thermostat is responsible only for the temperature in the refrigerator compartment, starting and stopping the compressor according to the sensor in the upper chamber. In this case, the freezer operates in pulse mode. Reducing the load on the main circuit indirectly affects the lower compartment.
The effectiveness of this method depends on the ambient temperature in the room. In the summer, when the room is hot, the compressor will be forced to work more often, and it will not be possible to completely stop freezing in the lower chamber even at minimum settings.
Method of shutting off the air dampers (for No Frost)
In models with the system No Frost cold is generated in a separate evaporator and pumped by a fan into cameras through special channels. An air damper (damper) is often installed between the refrigerator and freezer compartments, which regulates the flow of cold air.
If your goal is to stop food freezing in the lower compartment, you can try to physically block the cold air supply channel. To do this, you will need to remove the plastic panel inside the freezer. It is usually secured with latches or screws.
- 🧊 Localization of the channel: Find the hole through which cold air enters from the evaporator.
- 🛑 Flow blocking: Carefully cover the hole with a dense material (foam plastic, rolled up towel) so that air does not enter the chamber.
- 🌡️ Temperature control: Make sure that the temperature in the main compartment does not rise above normal due to changes in circulation.
This method allows you to actually “turn off” the freezer, turning it into a regular refrigerator compartment or simply stopping the freezing process. However, the fan will continue to operate, moving air through the rest of the system, which can lead to excess condensation.
It is important not to damage the temperature sensors and defrost heater, which are often located in close proximity to the air ducts. Careless movement may result in broken wiring or damage to delicate controls.
Risks of blocked air ducts
If the cold air outlet is completely blocked, the sensor in the refrigerator compartment may not sense a decrease in temperature, and the compressor will run continuously, trying to cool the upper chamber. This will lead to overload of the motor and possible freezing of the evaporator.
Complete defrosting procedure as a way to turn it off
Often when asked “how to turn off the freezer,” users mean the need to defrost it. In two-chamber Biryusha with a drip system, the freezer requires manual defrosting. To do this, it is necessary to completely stop the operation of the unit.
The process begins by disconnecting the device from the power supply. All products should be removed or transferred to another cool place. The doors of both compartments are left open for free air circulation and acceleration of ice melting.
It is not recommended to use hair dryers, knives or other heating devices to speed up the process. A sudden temperature change can damage plastic case the evaporator, and a sharp tool can easily pierce thin tubes with freon.
| Stage | Action | Time execution | Important nuances |
|---|---|---|---|
| 1 | Disconnecting from the network | 1 minute | Remove the plug from the socket |
| 2 | Releasing the cameras | 10-15 minutes | Food in a thermal bag |
| 3 | Natural defrosting | 12-24 hours | Place rags on the floor |
| 4 | Removing moisture | 30 minutes | Wipe all surfaces dry |
| 5 | Startup | 2-3 hours | Work without load before loading |
After defrosting is completed and the moisture has been thoroughly wiped off, the refrigerator can be turned on again. It is recommended to load food only after the unit has reached operating temperature; this usually takes about 2-3 hours.
☑️ Checklist for proper defrosting
Saving energy during operation one chamber
If you don’t need the freezer all the time, but you can’t dismantle it, you can minimize its impact on energy consumption. An empty freezer uses less energy than a full one, since air is easier to cool than a mass of food. However, the compressor will still turn on according to the sensor in the refrigerator compartment.
For maximum efficiency in the "refrigerator only" mode, it is recommended to fill the free volume of the freezer with empty plastic bottles or insulating material. This will create a buffer zone and reduce heat inflow when opening the door of the main compartment (if they are connected by air flows).
It is also worth checking the door seals. If the rubber band on the freezer does not fit tightly, warm air will constantly enter there, causing the system to work more intensely. Adjusting the hinges or replacing the seal Biryusa can significantly reduce electricity consumption.
⚠️ Attention: Long-term operation of the refrigerator with the door of one of the chambers open or not tightly closed can lead to freezing of the evaporator and failure thermostat due to continuous operation.
Some users practice installing a separate time relay, but this requires the skills of an electrician and may violate the terms of the warranty. The easiest way is to simply reduce the temperature in the freezer to a minimum if the design allows independent adjustment (rare).
Typical errors and risks when interfering with the operation of the system
When trying to turn off part of the refrigeration circuit, owners often make mistakes that lead to expensive repairs. The most common problem is thermal imbalance. A compressor designed to operate with a certain load may overheat or, conversely, not have time to start, which leads to souring of the oil.
Another mistake is the use of chemical defrosters or boiling water. Aggressive chemistry can corrode the plastic and damage the coating of the evaporator, and boiling water will create a critical thermal shock. The metal contracts and expands at different rates, which leads to microcracks.
- ❄️ Freezing of the drainage: If defrosting is improper, water may freeze in the drainage tube, which will lead to the appearance of a puddle inside or under the refrigerator.
- 🔌 Power surges: Frequent switching on and off when experimenting with thermostat can be dangerous for the starting relay without using a stabilizer.
- 🔧 Mechanical damage: Strong pressure on shelves or walls when trying to reach the dampers can split the internal plastic.
If you If you noticed that after your manipulations the refrigerator began to make strange sounds, stopped turning off, or a burning smell appeared inside, stop using it immediately. In such cases, it is better to call a technician for diagnostics than to try to fix the problem yourself.
Frequently asked questions (FAQ)
Is it possible to completely turn off the freezer in Biryusa so that it becomes just a cabinet?
Technically, it is impossible to turn the freezer into a regular cabinet with room temperature, leaving the refrigerator running, in single-compressor models. It will always be colder than the environment, since part of the circuit or cold air passes through it. It will become completely warm only when the device is completely disconnected from the network.
Will the compressor work only on the refrigeration chamber?
The operation mode itself for cooling the main compartment is standard for the refrigerator. However, if you artificially limit heat transfer (for example, by blocking all channels), the compressor may operate in suboptimal mode, which will shorten its life. Short-term operation in this mode is safe.
How to defrost a freezer without defrosting the refrigerator?
In two-chamber models with one compressor, it is impossible to completely defrost the freezer while keeping the cold in the refrigerator compartment. When the compressor stops, heat will begin to penetrate everywhere. You can only isolate the food in the main compartment with blankets as much as possible and defrost quickly, but the temperature there will still rise.
Why does the Biryusa refrigerator not turn on for a long time after defrosting?
This may be due to the operation of the thermostat, which waits for the temperature to set, or to the thermal compressor protection relay, which blocks startup after overheating. Also check whether the doors are tightly closed - if the light sensor or magnetic switch does not work, the ventilation (if any) may not start.
