Many owners of modern household appliances mistakenly believe that the system No Frost completely eliminates the need to maintain the unit. Two-chamber models of the domestic brand Biryusa are indeed equipped with advanced moisture removal technologies, but this does not mean that the device works forever without human intervention. Periodic maintenance is necessary to maintain hygiene and efficient operation of the compressor.
Complete defrosting is required not to remove ice from the chambers, as in older models with a drip system, but to sanitize and clean hard-to-reach components. Ignoring this process can lead to unpleasant odors, bacterial growth, and even failure of the air circulation system. In this guide, we will look at all the nuances of preparing your refrigerator for “rest.”
Why the No Frost system needs defrosting
The system No Frost (or “no frost”) implies the presence of a fan that drives dry cold air through the chambers, preventing moisture from settling on the walls. However, the drainage system hidden behind the back panel of the freezer accumulates dust, lint and micro-food particles over time. This debris mixes with condensation and can turn into an ice plug.
If you do not carry out preventive maintenance, drainage hole it becomes clogged and there is nowhere for water to drain. As a result, liquid begins to accumulate at the bottom of the refrigerator compartment or, worse, freezes in the form of ice inside the cabinet. Once every 6-12 months, it is recommended to turn off the equipment so that this hidden ice melts and comes out naturally.
In addition, during downtime you will be able to thoroughly wash the shelves and drawers, which is impossible to do with the engine running. The cleanliness of the internal surface directly affects shelf life of products and the absence of foreign odors that can be absorbed into the plastic.
Preparation for the shutdown procedure
Before starting defrosting, it is necessary to empty the chambers of the contents. Take care in advance about where to place frozen and chilled foods. If it is winter outside, you can take supplies to the balcony, otherwise use thermal containers or thick blankets.
After releasing the cameras, disconnect the device from the power supply. To do this, unplug the plug from the socket. Do not pull on the wire, but hold onto the plug body to avoid damaging the insulation. Now you can begin to remove the removable elements.
- 🧊 Remove all glass shelves and grilles.
- 🥦 Remove the plastic boxes for vegetables and fruits.
- 🚪 Open the doors wide to allow warm air to flow in.
- 🧼 Prepare a container with soap solution and dry rags.
It is important not to leave the doors open in a draft if the room is very cold, since a sharp temperature change can negatively affect the plastic. It is better to carry out the procedure at room temperature.
Step-by-step instructions for defrosting
The process of natural thawing takes longer than the accelerated one, but is the safest for all components of the unit. Do not try to break off the ice with a knife or other sharp objects - this is guaranteed to damage the evaporator and leak freon.
☑️ Action plan for defrosting
Leave the refrigerator with the doors open for at least 12-24 hours. During this time, all the ice hidden in the drainage will have time to turn into water. In a two-chamber freezer Turks a significant amount of melt water can form, so it is recommended to lay old towels on the floor under the doors or place flat trays.
While the thawing process is underway, start washing the removed shelves and drawers. Use warm water and a mild detergent. Abrasive powders can scratch the plastic, making it dull and more susceptible to future stains.
What if you need to speed up the process?
You can place bowls of hot water inside the chambers. This will create steam and speed up the melting of the ice. However, do not place bowls on plastic bottoms - use a wooden board or towel to avoid melting the plastic.
Cleaning the drainage system and internal cavities
After the main ice has melted, you need to pay special attention to the drainage hole. It is usually located on the back wall of the refrigerator compartment. Gently clean it using a special brush or soft wire wrapped in cotton wool.
For disinfection, you can use a weak solution of vinegar or soda. Wipe down all interior surfaces, including door seals. It is in the folds of rubber that mold most often accumulates, which is difficult to notice upon a quick inspection.
Be sure to check the condition seal. If it is dirty, the door will not fit tightly and the compressor will work harder to try to compensate for the loss of cold. Pure rubber ensures tightness.
⚠️ Attention: It is strictly forbidden to use a hair dryer to speed up defrosting! Hot air can deform the plastic parts of the housing and damage the evaporator tubes, which will lead to expensive repairs.
Table: Comparison of defrosting methods
| Method | Execution time | Safety | Efficiency |
|---|---|---|---|
| Natural thawing | 12-24 hours | High | Maximum |
| Bowls with hot water | 2-4 hours | Medium | High |
| Fan (blowing) | 4-6 hours | High | Medium |
| Mechanical cleaning | 30 minutes | Low (dangerous!) | Low |
Starting the refrigerator after defrosting
When all surfaces have been washed and, most importantly, wiped dry, reassemble the refrigerator in the reverse order. Place shelves, drawers and racks in their proper places. Make sure that there are no puddles or wet spots left inside.
Now you can turn on the device. Don't download products right away! Let the refrigerator Biryusa run idle for 2-4 hours. During this time, the compressor will reach the required temperature and the system will stabilize.
Only after the refrigerator has reached coldness can you add food. If you put warm or room temperature food into a unit that has just been turned on, you will create an extreme load on the motor.
Typical mistakes during maintenance
The most common mistake is haste. Users try to speed up the process by using prohibited tools. Remember that the system No Frost has a hidden evaporator, which is very easy to damage. Repair after a tube puncture will require calling a technician and refilling with freon.
Another mistake is turning on the device before it has completely dried. Residual moisture can get on the electrical contacts or freeze in the channels, nullifying the entire defrosting procedure. Thoroughly dry all the corners of the chambers.
- ❌ Using sharp objects to chip ice.
- ❌ Using aggressive chemicals to wash plastic.
- ❌ Loading products until the temperature reaches.
- ❌ Ignoring cleaning the drainage hole.
⚠️ Attention: If, after defrosting and turning on, the refrigerator makes unusual sounds (gurgling, humming) or does not freeze, there may be an ice jam left in the system. In this case, repeat the defrosting procedure, increasing the shutdown time to 36 hours.
Frequently asked questions (FAQ)
Do you need to defrost the Biryusa No Frost refrigerator if there is no ice?
Yes, it is necessary. The absence of visible ice does not mean the system is clean. Preventative defrosting is necessary for hygiene and cleaning drainage channels from invisible ice and bacteria.
How long should a refrigerator be left unplugged?
The optimal time for complete defrosting of a two-chamber model is from 12 to 24 hours. This ensures that the ice in the hidden cavities behind the back panel thaws.
Can you clean the refrigerator with window cleaner?
Not recommended. Window cleaners often contain alcohol or ammonia, which can make the plastic brittle or change its color. It is better to use baking soda or special products for household appliances.
What to do if water appears on the floor after defrosting?
Most likely, the drainage hole is clogged. Try cleaning it with a soft syringe or brush. If the problem recurs, the drainage pan at the back of the refrigerator may have moved.
Does frequent defrosting affect the life of the compressor?
No, if you do it on a schedule (1-2 times a year). On the contrary, a clean heat exchanger and free air circulation reduce the load on the motor, prolonging its life.
