Why the Biryusa refrigerator does not turn off for a long time: 12 reasons and what to do

Does your refrigerator Biryusa work without interruption, hums like a tractor, and the food in the freezer is covered with an ice crust? This is not just a “feature” of Soviet technology - a signal of a malfunction that can lead to compressor failure or food spoilage. In 80% of cases, the problem is solved without calling a technician, if the cause is correctly identified.

This article is an analysis of all possible reasons why the refrigerator Biryusa (models 3K, 6K, 8K, 10K, 18K, 22K etc.) does not turn off, including nuances for devices with system No Frost and drip defrosting. We collected data from service manuals, reviews of owners and recommendations of plant engineers Krasnoyarsk refrigerator plant "Biryusa"so that you can diagnose the malfunction independently understand when to call a specialist.

⚠️ Important: If the refrigerator does not turn off for more than 12 hours in a row, this is a critical mode! Do not ignore the problem: overheating of the compressor leads to its failure (replacement cost - from 8,000 ₽).

1. Product overload: when the refrigerator “chokes”

The most common reason for continuous operation is impaired air circulation due to improper loading of products. Refrigerators Biryusa (especially older models) are not designed for the “American” style of storage, when the shelves are packed to capacity.

How does it work? The compressor cools the air, which must circulate freely throughout the chamber. If the products block the ventilation holes (in models with No Frost) or fit tightly to the back wall (in drip refrigerators), the temperature sensor does not record the actual cooling and the compressor continue to work.

• 🥦 Vegetables and fruits in plastic bags: block the air flow. In Biryuse 18K i 22K this is critical - the chambers are narrow and the ventilation is poor.
• 🥩 Hot dishes: increase the temperature in the chamber, forcing the compressor to wear out. Even warm soup in a 3-liter saucepan can cause a malfunction.
• 🧊 Ice in freezer: if the layer of ice is thicker than 5 mm, the temperature sensor reads data incorrectly and the compressor “thinks” that the chamber has not cooled.

✅ How to check: Turn off the refrigerator for 2 hours, unload the shelves by 30%, make sure that the food does not touch the back wall. If, after turning on, the compressor begins to turn off, there is a problem with the load.

2. Thermostat malfunction: when the “brain” of the refrigerator is lying

Thermostat (or thermostat) is the "brain" of the refrigeratorthat determines when to turn on/off the compressor. In 30% of cases of continuous operation, it is he who is to blame. Signs of breakdown:

• 🔄 The compressor works without pauses (even when the chamber is empty).
• ❄️ In the freezer the temperature is below -24°C, and in the fridge compartment - about 0°C (food freezes).
• 🔊 Clicks when turning the thermostat knob (in mechanical models Biryusa 3K, 6K).

🔧 How to diagnose:

1. Disconnect the refrigerator from the mains.
2. Remove the thermostat protective casing (usually located inside the chamber, under the plastic panel).
3. Check the contacts for oxidation or burning.
4. Call the thermostat multimeter in resistance mode. At room temperature, the resistance should be 0 Ohm (contacts are closed).

If the thermostat is faulty, it needs to be replaced. For models Biryusa thermostats are suitable. data-i="114">(for single-chamber) and K-59 (for single-chamber) and TAM-133 (for double-chamber). Cost - from 800 to 1,500 ₽.

How to temporarily bypass a faulty thermostat?

If the thermostat is broken and there is no way to replace it right away, you can connect the compressor directly through the relay, but this is risky:

1. The refrigerator will work without stopping until you turn it off. sockets.

2. The temperature in the chamber will drop to -30°C, the food will freeze.

3. The compressor may overheat after 6-8 hours of continuous operation.

Use this method only as a last resort and do not leave the refrigerator without supervision!

3. Freon leak: when the refrigerator “loses blood”

If the Biryusa refrigerator works without stopping, but does not freeze. - with a 95% probability this is a freon leak. Freon (refrigerant) circulates through the system and removes heat. When there is a shortage of it, the compressor tries to “catch up” the cold, but to no avail.

Causes of leakage:

• 🔧 Mechanical damage: puncture of the circuit when defrosting with a knife or moving the refrigerator.
• 🕰️ Corrosion of tubes: in older models (Turk 3K, 6K manufactured before 2005), copper tubes oxidize and crack.
• 🔥 Overheating of the compressor: leads to increased pressure and microcracks in the circuit.

🔍 How to determine a leak:

1. Turn off the refrigerator and defrost it.
2. Turn on the empty refrigerator to maximum mode.
3. Touch condenser (grid at the back): if it cold —there is no freon.
4. Shine a flashlight on the tubes: look for oil stains (freon comes out along with oil).

⚠️ Attention: Refilling freon yourself is dangerous! The refrigerant is toxic, and special equipment is needed for refilling. The average cost of the service is 3,500 rubles (including leak diagnosis).

4. rents out the refrigerator

The compressor is the most expensive part of the refrigerator (the price of a new one is from 8,000 ₽). If it is worn out or overheats, the refrigerator may work without stopping, but not cool:

🛠️ How to extend the life of the compressor:

• 🌡️ Not place the refrigerator next to the battery or stove (the optimal temperature around is 18-22°C).
• 🔌 Use voltage stabilizer (compressors Biryusa sensitive to surges).
• 🧹 Once a year, clean the condenser from dust (with a vacuum cleaner or a soft brush).

5. Problems with the door seal: when the cold “leaks away”

A worn or dirty seal allows warm air to pass through, causing the compressor to work longer. In refrigerators Turk seals often leak. elasticity due to:

• 🧽 Grease and dirt (especially if the door is washed with aggressive detergents).
• 🕰️ Natural aging (the service life of the seal is 5-7 years).
• 🔄 Deformation (if the door is often opened with a jerk).

🔍 How to check the tightness:

1. Take a sheet of A4 paper.
2. Close the door, holding the sheet between the seal and the body.
3. Pull the sheet towards you: if it slipped out easily the seal is not tight.

🛠️ How to restore seal:

1. Wash the seal with warm water and soap, dry.
2. Apply silicone grease (for example, WD-40 Specialist).
3. If the seal cracked - replace it (cost for Biryusa - from 1,500 ₽).

1. Inspect the seal for cracks and contamination

2. Check the tightness with a sheet. paper

3. Clean the seal with soapy water

4. Apply silicone grease

5. Adjust the door hinges (if there is misalignment)-->

6. Temperature sensor malfunction (in models with electronic control)

Refrigerators Biryusa new series (for example, Biryusa 130K, 140K) are equipped with electronic temperature sensors. If the sensor breaks, the control unit receives incorrect data and forces the compressor to work continuously.

Signs of sensor failure:

• 📉 Temperature in the chamber does not correspond to the installed one (for example, +5°C is set, but in reality +10°C).
• 🔄 The display shows an error (codes E1, E2, E5 for different models).
• 🔊 The compressor turns on for 1-2 minutes and turns off (the cycle is repeated constantly).

🔧 How diagnose:

1. Disconnect the refrigerator from the network.
2. Remove the back panel in the refrigerator compartment (the sensor is usually located next to the evaporator).
3. Test the sensor with a multimeter: the resistance should change when the temperature changes (for example, when heated by a hairdryer).

⚠️ Attention: In refrigerators Biryusa with a system No Frost sensors often fail due to icing. If there is ice on the sensor, defrost the refrigerator for 24 hours before checking.

7. Capillary tube clogged: when a “blockage” interferes with cooling

The capillary tube is a thin channel through which freon enters the evaporator. If it becomes clogged (for example, due to moisture or oil), freon does not circulate, and the compressor runs idle.

Signs of a blockage:

• ❄️ The freezer works, but the refrigerator does not.
• 🔥 The compressor is very hot, but the condenser remains cold.
• 🕒 The refrigerator does not turn off for more than 8-10 hours.

🔧 How to fix:

It is almost impossible to clean the capillary tube yourself - it requires special equipment (hydraulic press) and experience. The average cost of cleaning in the service is 4. 000 ₽. If the blockage is severe, you may need to replace the tube (from 5,000 ₽).

8. External factors: when the problem is not in the refrigerator

Sometimes the refrigerator Biryusa turns off due to external reasons not related to breakdowns:

• 🌡️ High room temperature (above 30°C). The compressor cannot “catch up” with the norm.
• 🔌 Low voltage in the network (below 200V). The compressor wears out, but does not cool.
• ☀️ Direct sunlight on the case. Especially important for refrigerators on balconies.
• 🚪 Frequent opening of the door (for example, in families with children).

📌 How to check:

1. Measure the temperature in the room (optimally - 18-22°C).
2. Check the voltage in the socket with a multimeter.
3. Make sure that the refrigerator is no closer than 5 cm from the wall (for ventilation).

If the problem is in external factors, the compressor will turn off after they are eliminated (for example, after ventilating the room or installing a voltage stabilizer).

FAQ: Frequently asked questions about Biryusa refrigerators

❓ Why does the new Biryusa refrigerator work without stopping for the first day?

This is normal! When you turn it on for the first time, the refrigerator pushes cold into the empty chambers. If after 24 hours the compressor does not turn off, check super freezing mode (it may be on).

❓ Is it possible to replace the thermostat yourself? Biryusa?

Yes, if you have experience working with electrics. For models Biryusa 3K-18K a thermostat is suitable K-59 or TAM-112. The main thing is when connecting! disconnection. do not mix up the wires when connected! Take a photo of the circuit before disconnecting.

❓ How long should the compressor work in normal?

In refrigerators Biryusa the work/rest ratio of the compressor depends on the model:

• Old models (before 2010): 20-30 minutes work, 40-50 minutes rest.
• New models (after 2015): Works for 10-15 minutes, rests for 20-30 minutes.

If the compressor runs for more than 1 hour without pauses, this is a reason for diagnostics.

❓ What to do if the Biryusa refrigerator does not turn off and is buzzing loudly?

Urgently disconnect it from the network! A loud hum may indicate:

• A jammed compressor (needs repair or replacement).
• A foreign object gets into the fan (in models with No Frost).
• Breakage of the motor winding (diagnostics with a multimeter is required).

❓ How often do you need to defrost the Biryusa refrigerator?

Depends on the model:

• Drip refrigerators (Biryusa 3K, 6K, 8K): once every 3-4 months.
• No Frost (Biryusa 130K, 140K): once every 6-12 months (but check the drainage hole monthly!).

If there is ice thicker than 5 mm on the back wall, defrost immediately!
