A smelly dryer is not only unpleasant, but can transfer odor to otherwise clean clothes. Why does my dryer smell? Lint buildup in the exhaust vent can limit airflow and promote mold growth. A thorough vent cleaning should remove any buildup and solve the problem. Use these troubleshooting tips to identify, eliminate, and prevent odor when your dryer smells bad.
What to Do When Your Dryer Smells Bad
Pinpointing dryer odor can seem like a mystery but there are usually several common causes with specific solutions. We’ll provide a step-by-step guide to eliminating odor but, first, here are some reasons why your dryer smells bad.
Why Does My Dryer Smell?
When your clothes dryer stinks the first step in banishing odor is to identify the source of the smell.
These are the most likely reasons your dryer smells bad:
- Lint buildup in the exhaust vent: If you skip your annual dryer vent cleaning, lint can accumulate in the exhaust vent and limit airflow. Poor circulation then results in the development of smelly mold and mildew. You may also notice that the dryer isn’t drying well due to poor airflow.
- Smelly clothing: Sweaty clothes or items with smelly stains don’t always come clean in the washer and can transfer their odor to the dryer. Often, the dryer smells bad when running as the heated airflow carries the smell.
- Pest infiltration: Wondering why my dryer smells like something died in it? Animals can get into the exhaust vent via the outside vent opening, creating a nest in the hosing.

Once you’ve identified why your dryer smells bad, proper cleaning with the right methods can eliminate odor.
