1. The most basic method is to adjust the temperature compensation to 0 first, then turn off the refrigerator (directly shut down without temperature compensation), unplug the power supply, take out all the things and drawers in the frozen layer, let the frost in it melt naturally, dry it with a rag, and then restore it. 2. Cut off the power supply of the refrigerator, clean up the items in the refrigerator, slowly blow the ice with a hair dryer or an electric fan, and add a towel to the bottom of the refrigerator to absorb water. After the wind blows, the frost will melt quickly, and it will be easier to remove it. After the ice surface is completely cleaned, it is best to wipe it with a clean towel dipped in venom, and then wipe it with clear water. 3. After disconnecting the refrigerator, take out the food in the box, and then according to the size of the freezer, put one or two aluminum lunch boxes in boiling water and put them in the freezer. After a few minutes, the frost on the freezer wall begins to fall off (if it hasn't fallen off, you can pull it gently with your hand). If there is no metal evaporation plate at the top of the freezer, the lunch box filled with boiling water should be covered to prevent the plastic inner wall from being deformed due to sudden temperature rise at low temperature. This method is much more time-saving than power failure self-heating defrosting. 4. After defrosting (deicing) the refrigerator every time, dry the freezer with a towel, and then coat a layer of vegetable oil on the surrounding inner wall. The next time it frosts, the suction between the frost and the refrigerator wall is greatly reduced because it adheres to the refrigerator wall containing oily components, so it is easy to peel off the hard blocks without much effort. 5. When it is necessary to defrost (de-ice) the refrigerator, first cut off the power supply of the refrigerator, and then aim the electric fan or hair dryer at the freezer and turn it to the maximum. After the wind blows, the frost will melt quickly, and it will be easier to remove it. After the refrigerator has been used for a week or half, it is best to turn off the power and open all the refrigerator doors. When the ice melts completely, turn on the power again. It would be better this way.
