If your dryer drum smells, follow these cleaning tips:
1. Wipe the drum interior with a damp cloth.
2. Clean the lint filter by pulling it out and removing the lint. Also, wash it under running water to remove extra lint and allow it to completely dry.
3. Clean the condenser. For instructions on how to clean the condenser, visit this page.
4. Wipe the moisture sensor with a damp cloth and a little bit of vinegar. The sensor is located by the lint filter.
