Owners of modern household appliances are often faced with the misconception that units with the system No Frost do not require defrosting at all. This is not entirely true, and ignoring routine maintenance can result in reduced compressor efficiency. Despite the name “dry freezing”, moisture is still released from the food and gradually accumulates in hard-to-reach places of the evaporator.
The process of turning off the equipment for prevention is necessary to give the equipment a “rest” and remove the ice coating invisible to the eye. In this article, we will look in detail at why this needs to be done, how to properly prepare the device for the procedure, and what absolutely cannot be done during the process.
Following simple operating rules will extend the life of your device refrigeration equipment years. Many users do not even suspect that strange sounds or deterioration in the quality of freezing are often solved by proper defrosting.
⚠️ Attention: Before starting any manipulations, be sure to disconnect the device from the power supply. Working with electrical appliances under voltage is prohibited.
Why the No Frost system needs defrosting
The system No Frost (which translates as “no frost”) really prevents the formation of visible ice on the walls of the chambers. However, this does not mean that the water completely disappears. Moisture is removed using fans and heaters, but some of the condensation can settle in the drainage system and on the evaporator itself, hidden behind plastic panels.
Over time, this layer of ice becomes thicker, which impedes air circulation. Circulation of cold air is a key element in the operation of such models. If the channels are clogged with ice, the compressor is forced to work longer and harder to maintain the set temperature.
Regular preventative defrosting allows:
- ❄️ Remove hidden ice shell from the evaporator, which cannot be removed without complete defrosting.
- 🔇 Reduce the noise level, since nothing will interfere with the fan rotating.
- ⚡ Save energy by returning heat exchange to its original efficiency.
If you ignore this procedure, ice can block the temperature sensors, which will lead to incorrect operation of the electronics. In some cases, this causes an error to appear on the display or the motor to run endlessly.
Preparing for the defrosting process
Before starting the process itself, it is necessary to properly prepare the space and contents of the chambers. This will take some time, but will ensure food safety and cleanliness in the kitchen. You should not start the procedure if you do not have at least 3-4 free hours.
First, empty the cameras of all products. If it's winter outside, you can take perishable goods to the balcony. In the warm season, use thermal bags or ice packs so that the food does not spoil while the thawing process is in progress defrosting process.
Next, you should remove all removable elements: shelves, drawers, egg trays and containers on the door. Plastic becomes brittle at low temperatures, so remove parts carefully, without sudden movements. It is better to wash them with warm water and a mild detergent while the equipment is turned off.
Be sure to turn off the water supply if an automatic ice maker is connected to your device. This will prevent leaks in the fluid supply system during downtime. After this, you can proceed to directly turning off the power.
Step-by-step algorithm of actions
The most important stage is the correct shutdown and waiting. Many users try to speed up the process by using a hairdryer or hot water, but for equipment Samsung with dry freezing this can be dangerous. A sudden temperature change can damage plastic elements or even cause cracks in the evaporator tubes.
Follow the proven algorithm:
- Turn off the device with the button on the control panel (if available) or simply unplug the plug from the socket.
- Leave the refrigerator and freezer doors completely closed open.
- Place prepared towels on the bottom of the chambers and in front of them to absorb moisture.
- Expect the ice to completely melt naturally. This may take from 10 to 24 hours depending on the thickness of the ice.
⚠️ Attention: Do not use sharp objects (knives, screwdrivers) to chip the ice. Damage to the evaporator circuit will lead to freon leakage and costly repairs.
While waiting, you can clean the rubber seals. Dirt on them prevents the door from sealing tightly, which will lead to re-growth of ice in the future. Wipe them with a damp cloth with vinegar or mild soap.
☑️ Ready to turn on
After all the ice has melted, thoroughly wipe the internal surfaces with a dry cloth. Make sure the drainage hole (usually located on the back wall of the refrigerator) is clear of debris. You can carefully clean it with a special brush or cotton swab.
What you should absolutely not do
There are a number of myths and dangerous advice that can be found on the Internet. Following them can turn a simple defrost into a cause of failure. Appliance safety should be a priority, so avoid the following actions.
Never use a hair dryer to dry or accelerate the melting of ice inside the chambers. A directed jet of hot air can deform the thin plastic of the internal panels, and condensation formed from temperature changes can get on the electrical contacts.
It is also prohibited to pour boiling water on the walls or shelves for quick melting. Sudden heating causes thermal shock to materials. Plastic may crack and glass shelves may break. In addition, a large amount of hot water can damage temperature sensors.
Table of common errors and their consequences:
| Action | Possible consequence | Risk of breakage |
|---|---|---|
| Chipping ice with a knife | Evaporator puncture, freon leak | Critical |
| Use of a hair dryer | Plastic deformation, short circuit | High |
| Turn on with open doors | Compressor overheating, freezing | Medium |
| Washing with hot water | Cracks in panels and shelves | Medium |
Another common mistake is turning on the device ahead of time. If there is water or ice left inside, the system may not start the defrost cycle correctly, which will lead to malfunctions of the electronics.
Completion and first start-up
When you are sure that the inside is dry, clean and all parts are in place, you can start starting. First, put all the drawers and shelves in place. Make sure that they are fixed correctly and do not distort the structure.
Plug the cord into the outlet. Don't load products right away. Let the refrigerator run idle for at least 2-3 hours. During this time, it will reach the required temperature, and the sensors will stabilize. Only after this can you add food.
What to do if a strange sound appears after switching on?
If you hear gurgling or hissing in the first hours of operation, this is normal. The refrigerant begins to circulate through the system. If the sound does not stop after a day, contact the service.
Check the operation of the system No Frost. A few hours after startup, the walls should be dry and the air inside should be uniformly cold. If you notice water under the drawers or on the walls after 24 hours, the drainage hole may be clogged.
For models with a display, check to see if the error indicators are on. If everything is in order, the equipment is ready for full operation. Regular prevention will help you avoid serious problems in the future.
Frequently asked questions and answers
Users often ask questions about the specifics of servicing their models. Below are the answers to the most popular of them, which will help dispel doubts.
How often should you defrost a Samsung refrigerator with No Frost?
It is recommended to carry out complete defrosting and preventive cleaning once every 6-12 months. If you notice a decrease in the efficiency of freezing or the appearance of extraneous sounds, you should carry out the procedure earlier.
Is it possible not to remove food during defrosting?
No, the food must be removed. Firstly, they will interfere with the circulation of warm air, and the ice will take a very long time to melt. Secondly, as the temperature inside the chambers increases, food may begin to deteriorate.
Why does the refrigerator not freeze for a long time after defrosting?
This may be due to the fact that you loaded too many warm foods at once. It could also be due to insufficient downtime before turning on. Let the equipment run empty for several hours.
Do you need to lubricate the seals after defrosting?
Yes, this is a useful procedure. Wipe the rubber seal with glycerin or special silicone grease. This will preserve the elasticity of the rubber and ensure a tight fit of the door.
Following these simple recommendations will ensure stable operation of your refrigerator Samsung. Remember that careful use of equipment reduces the likelihood of sudden breakdowns and maintains the freshness of your products.
