Safety first: Unplug the dryer before cleaning internal components.

Deep clean condenser and tray: Remove the condenser unit and wash it thoroughly with warm soapy water. Clean the condensate tray and channels to remove slime and residue.
Dry interior: Leave the dryer door open between uses to allow the drum and seals to dry out.
Run a hot maintenance cycle: Run an empty high-temperature cycle periodically to help kill bacteria and dry internal components.
Room ventilation: Ensure the laundry room is well ventilated to reduce humidity buildup.
