Dryer has a musty or moldy odor that transfers to clothes.

Safety first: Unplug the dryer before deep cleaning.

Steps:

• Clean drum: Wipe the drum interior with a solution of mild detergent and warm water, then with a diluted white vinegar solution. Dry with a clean cloth.
• Clean lint filter and housing: Wash the lint filter with warm soapy water and dry. Vacuum the housing thoroughly.
• Condenser/heat exchanger: On condenser/heat pump models, remove the heat exchanger (if user-removable) and rinse according to the manual. Ensure it is fully dry before reinstalling.
• Run a hot cycle: Run an empty high-heat cycle to help dry and deodorize internal surfaces.
