Does the refrigerator consume a lot of electricity after several years of use?

Theoretically, it is usually 8- 12 years. The refrigerator used for ten years has twice the power as when it was first used. Therefore, if the refrigerator is noisy, consumes a lot of electricity, has poor cooling effect, leaks water and trembles during operation, it will be upgraded. The refrigerator is too old, and there is more and more dust in many parts of the body. If it is not cleaned, it is easy to cause short circuit. The functions of preservation and sterilization will be reduced, which will lead to the smell of food and will not keep fresh. At the same time, the refrigerant will also leak, polluting the environment and endangering health.
