How to disable defrosting on a Biryusa refrigerator: instructions for everyone models

Refrigerators Biryusa are known for their reliability and adaptability to Russian operating conditions. However, the automatic defrosting function, which is present in most modern models, does not always suit users. Some people want to save energy, others want to reduce the noise from the compressor, and some simply prefer manual control over the process. In this article we will figure out how to properly turn off defrosting on refrigerators Biryusawithout disrupting the operation of the equipment and without losing the warranty.

It is important to understand that the procedure differs depending on type of defrosting system (drip, No Frost, manual) and refrigerator model. We will look at universal methods, as well as nuances for popular series, such as Biryusa-10, Biryusa-18 and Biryusa-22. If you are not confident in your abilities, it is better to contact a specialist, since incorrect actions can lead to damage to the thermostat or compressor.

Why do users want to disable automatic defrosting

Automatic defrosting was invented for convenience: the refrigerator itself regulates the formation of ice and maintains the optimal temperature. But in practice, this function does not always live up to expectations. Here are the main reasons why owners decide to turn it off: Biryusy. Frequent defrosting cycles cause the compressor to work harder, which increases energy consumption by 10–15%. Biryusy decide to turn it off:

• 🔌 Increased energy consumption. Frequent defrost cycles cause the compressor to work harder, which increases energy consumption by 10-15%.
• ❄️ Ineffective ice removal. In models with a drip system, ice may remain on the back wall, and No Frost sometimes “dries out” food.
• 🔊 Noise during operation. No Frost fans and heating elements create additional noise that disturbs you at night.
• 🕒 Inconvenient defrosting schedule. The refrigerator may start a cycle at the most inopportune times, for example, when you are sleeping or cooking.
• 🛠️ Repair or replacement of parts. If the defrost sensor breaks down, temporarily disabling the function allows you to continue using the refrigerator until it is repaired.

However, before you start disabling, consider: turning off the defrost completely can lead to ice buildup and deterioration of cooling. If you live in a region with high humidity, manual control will require regular intervention - approximately once every 1-2 months.

Types of defrosting systems in Biryusa refrigerators

To properly turn off defrosting, you need to know which system is installed in your model. Biryusa produces refrigerators with three main types:

If you are not sure what system is in your refrigerator, look in operating instructions or look at the technical specifications sticker (usually on the inside of the door or on the back body). In models with No Frost disabling defrosting can lead to fan icing and breakdown, so here it is better to adjust operation intervalsrather than disabling the function completely.

⚠️ Attention: In refrigerators Biryusa with a system No Frost complete disabling of defrosting can cause freezing of the evaporator and failure of the fan. It is recommended to reduce the frequency of cycles, and not turn them off completely.

Step-by-step instructions: how to disable defrosting on Biryusa with a drip system

If your refrigerator equipped drip defrosting system (most common in models like Biryusa-10K, Biryusa-18), you can disable automatic mode in two ways: through control panel or mechanical thermostat. Let's consider both options.

Method 1: Through a button or menu (electronic control)

In models with an electronic display (for example, Biryusa-22S), defrosting is disabled through the menu:

1. Press and hold the button Super Cool (or Frost Free) for 5 seconds until the indicator lights up.
2. Use the buttons +/– to go to the item Defrost (or Auto Defrost).
3. Press the selection button (usually OK or Select) and set the value Off.
4. Confirm the changes and wait for the sound signal.

If your model does not have a separate defrost button, try the combination: Mode + Temp ↑ (hold for 3 seconds). This works for some refrigerators. without a display (for example, Biryusa 2018–2023 model years.

Method 2: Through a mechanical thermostat (older models)

In refrigerators without a display (for example, Biryusa-10) defrosting is controlled by a thermostat. To turn it off:

1. Disconnect the refrigerator from the power supply (unplug the plug from the socket).
2. Remove the protective cover of the thermostat (usually located inside the chamber, next to the lamp).
3. Find the small lever or switch labeled Defrost or A/D (Auto Defrost).
4. Move it to position Off or Manual.
5. Put the cover in place and turn on refrigerator.

⚠️ Attention: If, after turning off defrosting, the refrigerator starts working without stopping or does not cool, it means that you have set the thermostat incorrectly. Return the lever to its original position and contact the technician.

Features of turning off defrosting in Biryusa refrigerators with No Frost

The system No Frost is more complex than the drip system: here the timer, heating element and fan. Disabling the function completely may result in evaporator icing and damage. However, you can:

• ⏳ Increase the interval between cycles defrosting (from 8 to 12-24 hours).
• 🔄 Turn off only the sound signal (if it is annoying).
• ❄️ Reduce the intensity of the fan (in some models).

To do this:

1. Press the button No Frost for 10 seconds until the indicator flashes.
2. Use the buttons +/– select the mode Eco or Long Defrost.
3. Confirm the selection. The refrigerator will reboot.

In models Biryusa-130NF and Biryusa-140NF you can disable defrosting the freezer compartment separately from the refrigerator compartment. For this:

1. Press "Freezer" + "Fridge" at the same time.
2. Hold for 5 seconds until the service settings menu appears.
3. Select "Defrost Freezer" → "Off".

What to do if the defrost disable button does not work

Sometimes users encounter the problem The refrigerator Biryusa does not respond to attempts to turn off defrosting. The reasons may be different:

• 🔋 Failure in the electronic module (reboot required).
• 🔧 Sensor failure defrosting (needs replacement).
• 📱 Blocking the function by the manufacturer (in some models after 2020).

Try the following steps:

1. Restart the refrigerator: unplug for 10 minutes, then plug it back in.
2. Reset the settings: press the button Reset (or Mode + Temp ↓) for 15 seconds.
3. Check the sensor: if the problem persists after resetting, The defrost sensor may be faulty (needs repair).

If the refrigerator displays an error (for example, E1 or F2), this may indicate a malfunction of the defrosting system. In this case attempts to disable the function programmatically can aggravate the breakdown - it is better to call a technician.

Decoding defrosting errors in Biryusa

E1 - malfunction of the evaporator temperature sensor.

F2 - problem with the heating element defrosting.

E3 - malfunction of the defrost timer.

F4 - open circuit of the fan (only for No Frost).

Manual defrosting after turning off the automatic mode

If you have disabled automatic defrosting, you will have to periodically defrost the refrigerator manually. Here's how to do it correctly:

1. Preparation: turn off the refrigerator, take out all the food, place containers to collect water.
2. Acceleration process: leave the door open, put a pan of hot water inside (not boiling water!).
3. Cleaning: after the ice melts, rinse the walls with a soda solution (1 tablespoon per 1 liter of water).
4. Drying: wipe all surfaces dry, then turn on the refrigerator.

The frequency of manual defrosting depends on operating conditions:

• 🏡 Home conditions (humidity 40–60%): once every 2–3 months.
• 🌧️ High humidity (more than 70%): once every 1–1.5 months.
• ❄️ Frequent opening of the door: once a month.

⚠️ Attention: Do not use a hairdryer or heater to speed up defrosting - this can damage the rubber seals and plastic parts. The maximum permissible temperature to accelerate melting is +40°C (for example, warm water in bowls).

Common mistakes and how to avoid them

When turning off defrosting, users often make mistakes that lead to breakdowns. Here are the most common ones:

Another typical problem is forgetting to turn back automatic defrosting after manual cleaning. If you temporarily disable the function, do not forget to return the settings to their original state after 1-2 days.

FAQ: Answers to frequently asked questions

Is it possible to disable defrosting on Biryusa-130 with No Frost?

Yes, but it is not recommended to disable it completely. In this model, you can increase the interval between defrosting cycles to 24 hours through the service menu (button No Frost + Temp ↑, hold for 8 seconds). A complete shutdown will lead to icing of the fan.

After turning off defrosting, the refrigerator began to freeze worse. What to do?

Return the settings to their original state and check if ice has formed on the evaporator. If the problem persists, the temperature sensor or thermostat may be faulty. In this case, a technician needs diagnostics.

How often should you defrost Biryusa-18 manually after turning off automatic defrosting?

At average humidity (40–60%) - once every 2 months. If frost or ice often appears in the refrigerator, reduce the interval to 1 month. Use desiccant (such as silica gel) to reduce ice formation.

Can defrost be turned off in the freezer compartment only?

Yes, in models with separate controls (for example Biryusa-22S or Biryusa-140NF). To do this, select Defrost Freezer → Offfrom the menu. The refrigerator compartment will operate as usual.

Is it true that turning off defrosting saves energy?

Yes, but not significantly - about 5-10% of total consumption. The main savings are achieved by reducing the load on the compressor. However, if you often defrost the refrigerator manually (for example, with a hairdryer), energy consumption may even increase.
