How to solve the problem of air-conditioning leakage in Thermo Fisher ultra-low temperature refrigerator? How to prevent the air-conditioning leakage in the refrigerator? After using the Thermo Fisher ultra-low temperature refrigerator for a long time, due to the aging and deformation of the magnetic sealing strip on the door, the cold air in the refrigerator leaks out, reducing the cooling effect. The method of inspection is to turn on the flashlight and put it into the Thermo Fisher ultra-low temperature ice phase, close the door, and carefully observe whether there are any light leakage gaps around the refrigerator. If you use washing powder and water, clean the sealing strip and remove the sealing strip at the light leakage spot. Peel it open, put in a piece of sealing tape, put the sealing strip as it is, and then check whether there is still light leakage. Check the patch repeatedly in this way until there is no light leakage. Thermo Fisher after-sales service, how to maintain the Thermo Fisher ultra-low temperature door seal
Apply a layer of talcum powder or talcum powder evenly on the surface of the Thermo Fisher ultra-low temperature refrigerator door seal and the contact area between the box and the door seal to prevent the door seal from breaking. Pulling the paint off the door frame can extend the life of the door frame and seal. Why do Thermo Fisher ultra-low temperature refrigerators use independent circuits? The Thermo Fisher ultra-low temperature refrigerator should be wired separately and should be as close to the main power switch as possible. Do not share a socket with other electrical appliances. This is because if the Thermo Fisher ultra-low temperature refrigerator and other electrical appliances use the same socket, the appliance will start frequently and cause voltage drops, especially in During peak power consumption, low voltage may cause the compressor with the nose function option to fail to start or automatically shut down. In severe cases, the refrigerator motor may be damaged.
