Why is there an odor inside the refrigerator?

1. The unique plastic smell of some plastic parts when the new machine leaves the factory is a normal phenomenon. After a period of use, the smell will gradually disappear. It is recommended that customers open the refrigerator door for ventilation before use, or wipe the inside of the refrigerator with clean water before using.
2. Long-time users:
(a) Check whether the food in the refrigerator has been stored for too long beyond the expiration date, and whether it has gone bad and smelly.
(b) Check whether the inside of the refrigerator and the deodorizer have not been cleaned for a long time.
(c) Check whether food with strange smell is stored.
