Why does my dryer smell moldy or musty?

A musty or moldy smell typically indicates that moisture is trapped somewhere in the vent system. Blocked airflow, long or kinked duct runs, or lint buildup create conditions that allow mold and mildew to grow.

How can I tell if the smell is from the dryer vent and not the washing machine?

Run your dryer on an empty setting for 10-20 minutes on a medium cycle, then smell the drum. If it smells musty with no load, the vent or dryer system is likely the source.

Can cleaning just the lint screen fix it?

Not always. While cleaning the lint screen is essential, odor-causing moisture and mold can also exist deeper in the vent run; therefore, professional inspection and vent cleaning may be required.

How often should I inspect or clean my dryer vent to prevent smells?

At minimum once a year for typical homes, but more often if you do frequent laundry loads, have pets, long ducts, or have experienced moisture or mold issues.

Will fixing the vent stop the smell and improve performance?

Yes. Once airflow is restored and moisture removed, the musty odor disappears, the dryer dries clothes more efficiently, and your laundry room environment improves.
