Smell/Odour from inside the Refrigerator
If food is stored without sealing, food odor is mixed with air inside to cause refrigerator odor.
In particular, fish smell is difficult to remove.
How to fix
Clean the inside of the refrigerator with alcohol/soap solution.
After it has been cleaned, set the temperature setting at stronger cooling level.
Use sealed containers to store food. Avoid keeping food item with strong odour in open
