Odors in a dryer or laundry load can come from trapped lint, moisture, mildew, poor ventilation, or residue left behind from previous wash cycles. In some cases, a burning or electrical smell may point to overheating, restricted airflow, or a failing dryer component.
If the odor appears only when the dryer is running, the dryer vent, lint screen, drum, and internal airflow path should be inspected. A clogged vent or lint buildup can hold moisture and odors while also making the dryer work harder than it should.
