Freezer interior has a strong, unpleasant odor that persists even after cleaning.

Safety first: Wear gloves and, if odor is strong, a mask when cleaning. Unplug the freezer before deep cleaning.

Steps:

• Remove contents: Discard any spoiled food. Remove shelves, baskets, and drawers.
• Clean interior: Wash all interior surfaces with a solution of baking soda and warm water or a mild detergent. Rinse and dry thoroughly.
• Clean drain pan: Access the drain pan under the unit and clean it with warm soapy water to remove any residue.
• Deodorize: Place an open box of baking soda or activated charcoal inside the empty freezer for several days.
• Check gasket: Clean the door gasket folds where mold can grow.

Note: Severe contamination after long-term spoilage may require replacing interior plastic parts or, in extreme cases, the entire unit.
