Here are some tips for solving various minor problems with your refrigerator. First, open the refrigerator door and insert a piece of paper inside, then close the door. If the paper can be easily pulled out, it indicates that there are some gaps inside the refrigerator. In this case, you can use a hairdryer to blow air into the gaps to remove any trapped air. Additionally, if your refrigerator emits strange odors, you can place a bowl of tea leaves, white vinegar, and baking soda inside the refrigerator for a whole day. The next day, you'll find that the strange odor has disappeared.
