Unpleasant musty or moldy odor inside the freezer, even after cleaning.

Safety: Unplug before deep cleaning; avoid harsh chemicals that can damage plastics.

Steps:

• 1. Empty and clean: Remove all food and shelves. Clean interior surfaces with a solution of baking soda and warm water.
• 2. Gasket cleaning: Pull back the door gasket folds and clean thoroughly with mild detergent and a soft brush.
• 3. Drain cleaning: Flush the defrost drain with warm water and a small amount of mild disinfectant, then rinse.
• 4. Air out: Leave the door open for several hours to dry completely.
• 5. Persistent odors: Place an open box of baking soda or activated charcoal inside to absorb remaining smells.
