The refrigerator should not be overfilled for maintenance, respiration, and disinfection. Adequate space should be left to facilitate the penetration of cold air through all stored items. In addition, refrigerators should be regularly disinfected. Wipe the refrigerator with diluted bleach water or 0.1% potassium permanganate water every 3-4 weeks, and regularly clean the refrigerator, including all layers, especially the filter screen, which is often a place where dirt and bacteria accumulate. 9 steps to clean and maintain the refrigerator surface cabinet: 1. It is best to clean the refrigerator shell every day. Use a slightly damp and soft cloth to wipe the refrigerator shell and handle every day. 2. Before cleaning the inner container, cut off the power supply and remove the food from the refrigerator. 3. Dip a soft cloth in water or tableware detergent, gently scrub, and then wipe off the detergent with water. 4. Remove the accessories inside the box and clean them with clean water or detergent. 5. When cleaning the "switches", "lights", and "temperature controllers" of the refrigerator, please screw the cloth or sponge dry. 6. After cleaning the inner wall, you can use a soft cloth dipped in glycerin (medical cork gel) to wipe the inner wall of the refrigerator once. It will be easier to wipe the next time. 7. Clean and wipe the sealing strip with a cloth soaked in alcohol. If there is no alcohol at hand, wipe the sealing strip with 1:1 vinegar water, and the disinfection effect is very good. 8. Use a vacuum cleaner or soft bristle brush to clean the ventilation grille on the back of the refrigerator. Do not use a damp cloth to avoid rusting. 9. After cleaning, plug in the power and check if the temperature controller is set to the correct position. Regular and appropriate maintenance can extend the lifespan of the refrigerator. Be sure to unplug the power plug before maintaining the refrigerator. 1. Regularly clean the dust on the back or bottom condenser and compressor of the refrigerator. A vacuum cleaner or brush can be used to remove dust. Be careful not to use a damp cloth to wipe dust from the refrigerator and compressor. 2. When the refrigerator is out of use for a long time, the power should be cut off first, all food inside the box should be taken out, the inside and outside of the box should be cleaned, and the door of the box should be opened for a few days to fully dry the box and dissipate the odor inside the refrigerator. 3. Check the drainage pipe. If the drainage pipe is blocked, water will leak into the refrigerator. You need to poke the drainage pipe with iron wire to remove anything that has accumulated on it. 4. Do not ignore the cleaning of the door sealing strip. Dilute the bleach with 10 times water and then wet it with a toothbrush. Finally, rinse off the bleach with water. The adhesive strip is dirty and prone to aging, which can affect the sealing of the refrigerator and increase power consumption. 5. Check vibration, noise, and compressor temperature. During operation, there should be no obvious vibration when touching the compressor casing, and there should be no noticeable sound of the compressor starting during the day. 6. Pay attention to checking if there are cracks on the power cord to prevent leakage. 7. Clean and dry the inside and outside of the refrigerator with warm water or neutral detergent, and open the refrigerator door for ventilation and drying for a day
