Restoring the operation of household equipment after planned or emergency defrosting requires strict adherence to the sequence of actions, especially when it comes to domestically produced equipment, such as Biryusa.
Incorrect starting of the compressor can lead to water hammer in the cooling system or failure of the start relay, which will require expensive repairs.
In this article we will analyze in detail how to safely turn on a two-chamber refrigerator Biryusa after defrosting, what time intervals need to be maintained and what to pay attention to when starting up for the first time.
Waiting for complete drying and temperature adaptation
The first and most critical stage is a pause after defrosting is completed, during which the equipment must remain disconnected from the power supply.
Many users make the mistake of turning on the unit as soon as the last drops of water have disappeared, but moisture may remain inside the thermal insulation layer and on the electrical contacts.
The average drying time is from 4 to 12 hours, depending on the humidity in the room and the duration of the previous defrosting.
In addition, temperature balance should recover naturally: if you washed the chambers with warm water or defrosted them in a hot room, the compressor will need time to cool down before load.
A sharp start of a hot motor will lead to overheating of the windings and a reduction in the engine's operating life.
Visually inspect the rear grille and base part: there should be no visible puddles or condensation.
⚠️ Attention: If defrosting was carried out using a hair dryer or other heating devices, the minimum waiting time before turning on increases to 24 hours to prevent damage to plastic elements and wiring.
Make sure that the floor under the equipment is absolutely dry, since moisture on the electrical contacts of the base can cause a short circuit when voltage is applied.
Checking the integrity of seals and door mechanisms
Before turning on the power, you need to make sure that the chambers are sealed, since after defrosting the rubber seals can be damaged deformed or displaced.
In two-chamber models Turkish there are often magnetic tapes that, if the door is installed incorrectly, may not fit tightly.
Carry out a thorough inspection along the entire perimeter of the doorway, paying attention to the corners where most often gaps form.
Use a simple test with a sheet of paper: hold the sheet between the door and the body and try to pull it out.
If the paper is pulled out without effort, it means tightness is brokenand the cold will go away, causing the compressor to work without stopping.
Also check the operation of the hinges and closers: the door should close smoothly, without jerking or squeaking.
- 🔍 Inspect the rubber circuit for cracks, creases or food debris that prevent a tight fit.
- 🚪 Check horizontal installation of the case, since the skew affects the automatic slamming of the doors.
- 🧹 Make sure that the shelves and drawers are installed level and do not interfere with the tight closing of the doors.
If you find dirt on the seal, wipe it with a soft cloth soaked in a weak soap solution and wipe dry.
Restoring position and leveling housing
Often, for proper defrosting and washing, the refrigerator has to be moved away or even tilted, so before turning it on it is important to return it to the correct spatial position.
Two-chamber models are sensitive to tilts: if the unit was at an angle of more than 40 degrees, oil from the compressor could flow into the cooling circuit.
In this case a long period of standing in a vertical position is required - at least 8-10 hours for the oil to flow back into the crankcase.
Alignment is done using adjustable support legs located in the front lower part of the housing.
Use a building level or simply pour a little water into a glass placed on the lid to assess the horizontal position.
Correct tilt back (about 2-3 degrees) ensures that the doors close independently under the influence of gravity.
| Parameter | Normal value | Consequences violations |
|---|---|---|
| Back angle | 2-3 degrees | The door does not close itself |
| Settling time | 4-10 hours | Risk compressor water hammer |
| Gap at the wall | Minimum 10 cm | Condenser overheating |
Do not forget to leave a technological gap between the rear wall of the refrigerator and the wall of the room for free air circulation.
Primary connection to the electrical network
The connection process must take place in strict sequence to avoid power surges that are dangerous for the control electronics.
First make sure that the socket is in working order and corresponds to the load capacity (preferably grounded).
Do not use extension cords or tees for permanent connection, as this increases the risk of fire and unstable operation.
Insert the plug into the socket and listen: in the first seconds you may hear a quiet hum or click of a relay, which is normal.
If the model is equipped with electronic control, the indicators on the display should light up, and after a few seconds a sound signal should sound.
In mechanical models Biryusa immediately after switching on, the thermostat will begin counting down the time until the motor starts.
⚠️ Attention: If, after turning on, you hear a loud crackling sound, a hum without starting the engine, or you smell a burning smell, immediately unplug the device from the network and call a technician.
Do not open the first 15-20 minutes after turning on doors, let the system gain initial cold and stabilize the freon pressure.
☑️ Check before turning on
Setting temperature modes and functions
After successfully starting the engine, it is necessary to set the correct temperature parameters for the refrigerator and freezer compartments.
In two-chamber refrigerators Biryusa with a system No Frost or drip defrosting, the settings may differ.
For mechanical control of turning the thermostat knob, set the value to the middle position (usually the number 3 or 4 out of 7).
If your model is equipped with an electronic control unit, the setting is made through the panel on the door.
Press the Mode or Tempbutton to enter the setting mode and use the arrows to select the desired value.
Optimal temperature for The refrigerator compartment is considered to range from +2 to +4 degrees Celsius.
- ❄️ For the freezer, set the value to -18°C for long-term storage of food.
- ⚡ Activate the "Super Freeze" mode only when fully loaded with fresh food, but for no more than 24 hours.
- 🌡️ Avoid setting minimum values on a constant basis, this leads to excessive energy consumption.
Remember that an empty refrigerator takes longer to reach temperature, so do not rush to load it with food in the first hours of operation.
What is Super Freeze?
The intensive freezing mode forcibly turns on the compressor for continuous operation, ignoring sensor readings until you turn it off or the timer expires.
Operation control and loading with products
Complete cooling of the internal volume to the specified parameters in a two-chamber refrigerator takes from 6 to 12 hours.
During this period, the compressor can work almost without stopping, which is a normal situation for reaching the operating mode.
Do not open the doors unless absolutely necessary, so as not to disturb the emerging microclimate inside the chambers.
Loading with products should be done gradually: first place those that require strong cooling, then the rest.
Make sure that the products do not block the ventilation holes, especially in models with the system No Frost.
Air circulation must be free, otherwise the temperature will vary greatly in different corners of the chamber.
If after 10-12 hours of operation the refrigerator does not turn off or the desired temperature has not been reached inside, check the tightness of the closure doors.
Frequently asked questions (FAQ)
How long should the Biryusa refrigerator turn off after turning on?
First cycle time operation depends on the room temperature and the volume of the chambers. Typically the first working cycle lasts from 1.5 to 3 hours. If the compressor runs for more than 5-6 hours without stopping and does not freeze, this may indicate a freon leak or malfunction.
Is it possible to plug in the Biryusa refrigerator immediately after defrosting?
It is strictly not recommended. It is necessary to wait at least 4 hours, and preferably up to 12 hours, so that the moisture from the electrical contacts and internal elements completely evaporates, and the pressure in the system stabilizes.
Why does the refrigerator hum after turning on, but there is no cold?
In the first 30-40 minutes after starting, the cold may not yet be felt, since freon circulates through the system. If after 2 hours of operation the walls of the chambers remain warm and the motor is humming, the system may have become airy or the compressor has broken down.
Is it necessary to wash the refrigerator before turning it on for the first time after a long period of inactivity?
Yes, hygienic treatment is required. Use a weak soda solution or a special household appliance cleaner. After washing, the doors should remain open until the internal surfaces are completely dry and the smell disappears.
