Why the Biryusa two-chamber refrigerator does not turn off: reasons and solutions

Does your two-chamber refrigerator Biryusa work around the clock, without turning off for rest? This is not just annoying noise - this mode is fraught with overheating of the compressor, increased energy consumption and food spoilage. In 80% of cases, the problem is solved without calling a technician if the cause is correctly identified. In this article we will analyze all possible malfunctionsfrom banal clogging of the capillary tube to breakdown of the electronic control unit, and also provide checklists for self-diagnosis.

Features of the models Biryusa (for example, series 130K, 140K, 220K) - sensitivity to voltage changes and a tendency to clog the drainage system. If the refrigerator does not turn off for more than 12 hours, this is already a cause for concern. But before you panic, check 5 basic parameters: the temperature in the chambers, the position of the thermostat, the cleanliness of the rear grille, the tightness of the seals and the presence of ice on the evaporator. First things first.

1. Incorrect temperature settings

The most common reason for continuous operation is excessive cooling requirements. In models Biryusa with mechanical control (for example, Biryusa 132K), the thermostat often accidentally gets knocked down when cleaning or rearranging products. Optimal values:

• 🥶 Refrigerator compartment: +4…+5°C (regulator position - between "2" and "3")
• ❄️ Freezer compartment: –18°C (position "3" or "4")
• ⚠️ Danger zone: position "5" and above - forced maximum cooling mode (the compressor will not turn off until the temperature drops to –24°C)

In electronic models (series Biryusa 220KE), the problem may lie in a settings failure after a power outage. Check the display: if the indicator Super Freeze or Fast Coolflashes, it means the forced cooling mode is activated. To turn off:

1. Press the button Super (or Turbo) for 3 seconds.
2. Make sure that all additional indicators.
3. Wait 2-3 hours - the compressor should turn off automatically.

⚠️ Attention: If after resetting the settings the refrigerator still does not turn off, do not try to re-activate the Super Freeze or Ecomodes. This may cause the compressor to overload.

2. Failure of the thermostat (thermostat)

The thermostat is the “brain” of the refrigerator, which sends a signal to the compressor to turn on/off. In models Biryusa the thermostats K-59 (for the refrigerator) and TAM-133 (for the freezer) most often fail. Signs of malfunction:

• 🔄 The compressor works without pauses, but the temperature in the chambers normal (check thermometer!).
• 💥 When you turn the thermostat knob, a click is heard, but the cooling mode does not change.
• 🔌 The refrigerator turns off only after manually pulling the plug from the socket.

How to check the thermostat yourself:

1. Disconnect the refrigerator from the mains and remove the protective casing of the thermostat (usually located inside the refrigerator compartment, under the plastic panel).
2. Disconnect the terminals and short them together directly (simulating the signal on switching on).
3. If the compressor worked the thermostat is faulty. If does not respond the problem is in the compressor or start-protection relay.

⚠️ Attention: In refrigerators Biryusa with a system No Frost the thermostat is often integrated into the electronic unit. Independent replacement without a connection diagram can lead to a short circuit.

3. Freon leak or clogged capillary tube

If the refrigerator Biryusa does not turn off, but at the same time does not freeze well - with a 90% probability freon is to blame. Signs of a leak:

• ❄️ The freezer compartment is covered with a thick layer ice (more than 5 cm).
• 🌡️ The temperature in the refrigerator compartment is above +10°C, despite the continuous operation of the compressor.
• 🔧 Oil stains are visible on the back wall (freon is mixed with the compressor oil).

Causes of leakage in Biryusa:

• 🛠️ Mechanical damage evaporator (for example, when breaking off ice with a knife).
• 🕳️ Corrosion pipes (typical for models older than 10 years).
• 🔥 Overheating of the compressorleading to depressurization of the system.

It is impossible to eliminate the leak on your own - it requires evacuating the system filling with freon. But you can check capillary tube for blockage:

1. Turn off the refrigerator and defrost it for 12 hours.
2. Wipe the condenser (grid on the back wall) and turn on the refrigerator.
3. If after 30 minutes the condenser remains cold the tube is clogged.

What to do if freon leaks through microcracks?

In this case, a complete replacement of the evaporator or cooling circuit is required. In Biryusa models older than 15 years, such repairs are not economically feasible - it is cheaper to buy a new refrigerator.

4. Malfunction of the compressor or start-up relay

The compressor in refrigerators Biryusa (for example, models DXM-101 or DXM-110) is designed for 12–16 on/off cycles per hour. If it works without stopping, the following breakdowns are possible:

How to check the compressor:

1. Turn off the refrigerator and remove the back cover.
2. Disconnect start-protective relay (black box on the compressor).
3. Close two outer terminals the relay with a wire (simulation of direct start).
4. If the compressor worked —the relay is to blame. If no the problem is in the compressor itself.

⚠️ Attention: In refrigerators Biryusa with an inverter compressor (series Inverter) you cannot check the windings with a multimeter - this can damage the electronic unit. Diagnostics should be carried out by a technician with an oscilloscope.

5. Problems with the electronic control unit

In modern models Biryusa (for example, 220KE-003, 140K-002) the electronic module is responsible for the compressor operating cycle. If it fails, the refrigerator can:

• 🔄 Work without stopping, ignoring sensor signals.
• 📛 Show errors on the display (codes E1, E2, E5).
• 🔌 Turn on independently after disconnecting from network.

Causes of failure of the electronic unit:

• ⚡ Power surges (typical for rural areas).
• 💧 Moisture ingress on the board (for example, during defrosting).
• 🕷️ Short circuit due to oxidation of contacts.

How to reset the control unit:

1. Unplug the refrigerator for 10 minutes.
2. Plug it back in and immediately press the combination buttons Temp + Super (hold for 5 seconds).
3. If the message appears on the display rSt the reset was successful.

6. Clogged drainage system or fan No Frost

In models with a system No Frost (for example, Biryusa 134K) continuous operation of the compressor is often associated with fan icing or clogged drainage hole. Signs:

• 🌀 Fan in the freezer does not rotate (shine with a flashlight - if the blades are iced up, this blocks the air circulation).
• 💧 There is a puddle of water under the refrigerator, but the chambers are dry.
• 🧊 On the back wall of the freezer thick layer of snow (more than 3 cm).

How to clean the system No Frost:

1. Unplug the refrigerator and defrost it for 24 hours.
2. Remove the back panel of the freezer (usually attached to 4–6 screws).
3. Remove ice from the fan and evaporator with a plastic scraper (not metal!).
4. Rinse the drainage hole with warm water and citric acid (1 tbsp. spoon per 1 liter of water).

⚠️ Attention: If after cleaning the fan still does not spin, check it with a multimeter. The winding resistance should be in the range of 200–500 Ohms. If the circuit is broken, replacement is required.

7. room temperature

Sometimes the refrigerator Biryusa does not turn off due to external conditionsand not internal failures. Check:

• 🔌 Network voltage: if it is below 190 V or above 240 V, the compressor is wearing out. Use a stabilizer.
• 🌡️ Temperature in indoors: if the kitchen is hotter than +30°C, the refrigerator physically cannot reach the set temperature.
• 🪟 Ventilation: the back grill should be 5–10 cm from the wall. If the refrigerator is built into furniture, check that the ventilation holes are not blocked.

Critical information: In Biryusa refrigerators with climate class N (normal) compressor will not turn off if the room temperature exceeds +32°C. For hot regions, you need models with class SN or T.

How to check the voltage:

1. Connect to the same socket multimeter or household voltmeter.
2. If the voltage is beyond 190–240 V, use a stabilizer with a capacity of at least 1 kW.
3. For models with an inverter compressor (for example, Biryusa 220K Inverter) the stabilizer must support sine wave (not quasi-sine!).

8. When to call a technician: critical. breakdowns

If you have checked all the points above, but the refrigerator Biryusa still does not turn off, most likely the problem is more serious:

• 🔧 Freon leak with depressurization of the system (requires soldering and refilling).
• 💥 Compressor inter-turn short circuit (needs replacement).
• 🔌 Failure of the electronic unit (in 30% of cases cannot be repaired).
• 🧊 Clogged filter-drier (replacement and vacuuming required).

Cost of repairs in service centers:

⚠️ Attention: Parts for refrigerators Biryusa over 10 years old may be discontinued before repairing, check with the service center for availability. spare parts for your model.

FAQ: Frequently asked questions about the continuous operation of the Biryusa refrigerator

My Biryusa 130K refrigerator works without stopping, but the temperature is normal.

Most likely faulty thermostat or start-protection relayis faulty. Check:

1. Turn the thermostat knob to "0" - if the compressor does not turn off, the problem is in the relay or electronic unit.
2. Test the thermostat with a multimeter (the resistance should change when you turn the knob).

If you are not sure, call a technician for diagnostics.

After defrosting, the Biryusa refrigerator does not turn off. This is. normal?

In the first 2-4 hours after defrosting, the compressor can work continuously - this is normal, since it produces cold. But if after 6 hours the situation has not changed, check:

• Is the drain hole clogged (in models with a drip system).
• Is the fan (in models No Frost).
• Are the temperature settings lost (especially if there was a power surge).

The Biryusa refrigerator is humming and does not turn off, and the freezer is very cold. What's wrong with it?

This is a typical symptom freon leaks in the refrigeration circuit or clogged capillary tube. Due to a lack of refrigerant, the compressor wears out, but the cold only enters the freezer. Solution:

1. Turn off the refrigerator and defrost it for 12 hours.
2. If after turning on the problem remains, call a technician to refill freon.

Can you replace the thermostat in the Biryusa refrigerator yourself?

Yes, if you have experience working with electrical appliances. You will need:

• Phillips screwdriver.
• New thermostat (for example, K-59 or TAM-133 —check the model according to the label on the old one).
• Multimeter for checking contacts.

Instructions:

1. Unplug the refrigerator.
2. Remove the plastic panel inside the refrigerator compartment.
3. Disconnect the thermostat terminals and remove it.
4. Install a new thermostat, connect the terminals in the same order.

If you are not sure, it is better to trust the replacement to a professional.

How long should the Biryusa refrigerator compressor work?

In normal mode, the compressor work/rest ratio:

• 🕒 Summer: 20–30 minutes working, 10–15 minutes resting.
• ❄️ Winter: works for 15–20 minutes, rests for 20–25 minutes.

If the compressor runs for more than 1 hour without pauses, this is a reason for diagnosis. Exception: modes Super Freeze or the first load of products after defrosting.
