How to defrost a No Frost refrigerator? Although modern technologies make life much easier for housewives, they still do not make it 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. How to do it correctly, you will learn in the article.
Refrigerator No Frost – does not require defrosting?
Many brands – Indesit, Bosch, Samsung, LG – have implemented the No Frost system, which literally translates as “no frost”. Do these refrigerators defrost? Stores tell us it’s not. In fact, appliances need to be defrost at least once a year.
Principle of operation. The chambers are equipped with fans that blow through the evaporator and evenly distribute cold air throughout the chamber. The accumulated moisture does not settle on the evaporator, but flows into a special section, from where it is then discharged into the reservoir and evaporates.
Sometimes snow or ice can still be seen on the walls or the evaporator. This happens if you often open the door, keep it open for a long time. Also, if the seal is defective, when warm air constantly penetrates into the chamber. The temperature in the compartment rises, moisture settles on the walls, and then freezes.
How often and for how long should a two-chamber refrigerator be defrosted? Once a year for 12-24 hours.
Do you need to clean the refrigerator and urgently load groceries? How many hours to endure? At least 1 hour, otherwise a large temperature difference will provoke an increased operation of the motor, which will lead to its wear. Holding the minimum period promotes the resumption of pressure and the gradual activation of the system.
Sequence of work
How to properly defrost the unit with No Frost:
- Unplug the refrigerator from the socket.
- Free the cameras from the products.
- Remove all parts from the compartment: grates, shelves, drawers, containers. Wash them separately using liquid detergent.
- Wipe the surfaces of the camera with a dry cloth. Collect debris and wipe off condensation.
- Dampen the sponge with soapy water and wash the compartment. To eliminate an unpleasant odor, you can use a solution of soda. Lemon juice and ammonia remove mold and mildew from seals.
Important! Do not use abrasive brushes or detergents. Otherwise, the coating of the camera may be damaged.
- Clean the ventilation holes with cotton swabs. Additionally, you can moisten them in a soda solution.
Attention! Do not unscrew the panels yourself, as this will void the warranty.
- Wipe surfaces dry. Now you can leave the refrigerator doors open during the day.
- After that, put all the elements in place and evenly distribute the products in the compartment. Close the door and connect the appliance to the network. Try not to open the doors for several hours until the temperature inside is restored.
How to wash the 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 defrosting can be done once a year. Follow simple rules:
- Remove contaminants in situ without leaving them for the next time. They dry up and become a source of an unpleasant odor.
- Do not put warm food into the unit. This will lead to an increase in temperature and the formation of ice.
- Cover foods with lids or bags.
- Review expiration dates on packages.
Even refrigerators with No Frost technology need to be allowed to thaw periodically, although not as often as refrigerators with manual and drip systems.
