The dryer emits a musty or moldy odor on startup or during drying.

Safety first: Unplug the dryer before deep cleaning. Avoid harsh chemicals that can leave flammable residues.

• Clean drum: Wipe the drum interior with a solution of mild detergent and warm water, then rinse with a damp cloth and dry.
• Run cleaning cycle: Run the dryer empty on high heat for 20–30 minutes to help remove residual odors.
• Clean lint path: Remove lint from the filter housing, internal ducts, and venting.
• Improve environment: Ensure the laundry area is dry and well-ventilated. Avoid storing chemicals or paints near the dryer that can off-gas and be drawn into the dryer.
