Get worse. In the process of repairing the refrigerator after opening the door, once the evaporator leaks or partially freezes, it is necessary to move the evaporator pipeline or replace the temperature sensor of the built-in evaporator. If the pipeline is not well matched, the refrigeration effect and performance will become worse and the shutdown will be slow. A refrigerator is an electrical appliance that keeps the temperature low. It can prevent food or other items from deteriorating by keeping them at a constant low temperature.
