Samsung Dryer: musty smell
What is this symptom?
If your Samsung dryer emits a musty smell, it may be due to mold or mildew growing inside the drum or seals. This odor can cling to your clothes and linger in the room during and after drying cycles. Common causes include moisture retention in the heat exchanger, lint buildup, and poor ventilation, which can all contribute to this unpleasant issue.
