Freezer interior has a strong, unpleasant odor even after removing spoiled food.

Safety: Unplug the freezer before deep cleaning. Avoid harsh chemicals that can damage plastics.

• Thorough cleaning: Remove all shelves and drawers. Wash interior surfaces with a solution of baking soda and warm water. Rinse and dry.
• Clean drain system: Access the drain trough and tube; flush with a mild disinfectant solution and then clean water.
• Ventilation: Leave the door open for several hours to air out the interior.
• Odor absorbers: Place activated charcoal or baking soda inside for several days to absorb residual smells.
• Persistent odor: If odor remains extremely strong, it may have penetrated insulation, which is difficult to remedy without major disassembly.
