Dryer has a musty or moldy odor inside the drum

Safety first: Unplug the dryer before deep cleaning.

Step-by-step checks:

• Clean drum: Wipe the inside of the drum with a solution of mild detergent and warm water, then with white vinegar. Dry thoroughly.
• Clean lint filter housing: Use a vacuum with a crevice tool to remove lint from the filter housing and front bulkhead.
• Clean venting: Remove and clean the exhaust vent and ducting to eliminate trapped lint and moisture.
• Usage habits: Avoid leaving damp clothes in the dryer for long periods. Run an empty high-heat cycle periodically to help dry out the drum and vent.

When to call a technician: Persistent odors after thorough cleaning may indicate hidden moisture or contamination that needs professional attention.
