How to defrost a Nou Frost refrigerator? Although modern technology makes life easier for housewives, it doesn’t make her completely carefree. Even units with the No Frost system need to be cleaned and washed, and for this, the equipment must be turned off and defrosted. You will learn how to do this correctly in the article.
No Frost Defrosting Refrigerator?
Many brands - Indesit, Bosch, Samsung, LG - have implemented the Nou Frost system, which literally translates as “without hoarfrost”. Do such refrigerators defrost? In stores, they convince us that not. In fact, the equipment needs to be defrosted at least once a year.
Principle of operation. Fans are installed in the chambers, which purge the evaporator and evenly distribute cold air throughout the chamber. Accumulated moisture does not settle on the evaporator, but flows into a special section, from where it is then discharged into the tank and evaporates.
Sometimes on the walls or the evaporator you can still notice snow or ice. This happens if you often open the door for a long time to keep it open. Also, with a defective seal, when warm air constantly enters the chamber. The temperature in the compartment rises, moisture settles on the walls, and then freezes.
How often and how long does it take to defrost a two-chamber refrigerator? Once a year for 12-24 hours.
Need to wash the refrigerator and urgently load food? How many hours to withstand? At least 1 hour, otherwise a large temperature difference will provoke increased motor operation, which will lead to wear. Exposure to a minimum period contributes to the restoration of pressure and the gradual activation of the system.
Work sequence
How to properly defrost a unit with Know Frost:
- Unplug the refrigerator.
- Free cameras from food.
- Remove all parts from the compartment: grills, shelves, drawers, containers. Wash them separately using liquid detergent.
- Wipe the surface of the camera with a dry cloth. Collect garbage and wipe off condensate.
- Moisten a sponge in soapy water and wash the compartment. To eliminate the unpleasant odor, a soda solution can be used. Lemon juice and ammonia remove mold and fungus from seals.
Important! Do not use abrasive brushes and detergent powders. Otherwise, the camera cover may be damaged.
- Clean the ventilation holes with cotton buds. Additionally, you can moisten them in a soda solution.
Attention! Do not unscrew the panels yourself, this will invalidate the warranty.
- Wipe the surfaces dry. Now you can leave the refrigerator door open for a day.
- Then put all the elements in place and evenly distribute the products in the compartment. Close the door and connect the equipment to the network. Try not to open the doors for several hours until the temperature inside is restored.
How to wash a refrigerator without defrosting? This can only be done if the unit is equipped with two motors. One department can be turned off and washed, while the other will work.
You need to take care of the inside of the refrigerator every day, then you can defrost once a year. Follow simple rules:
- Remove dirt in place without leaving them the next time. They dry and become a source of bad smell.
- Do not place warm foods in the unit. This will lead to an increase in temperature and the formation of ice.
- Cover food with lids or bags.
- Review expiration dates on packages.
Even refrigerators with Nou Frost technology need to be periodically allowed to thaw, although not as often as refrigerators with manual and drip systems.
