Freezer interior has strong unpleasant or chemical odors that persist even after cleaning.

Safety: Unplug the freezer before deep cleaning. If you suspect a refrigerant leak (oily residue, hissing), contact a professional.

• Remove all contents: Discard spoiled food. Remove shelves, baskets, and drawers.
• Thorough cleaning: Wash interior surfaces, shelves, and baskets with a solution of baking soda and warm water. Pay attention to corners and seams.
• Clean gasket and drain: Pull back the door gasket folds and clean thoroughly. Flush the defrost drain with warm water and mild disinfectant.
• Deodorize: Place an open box of baking soda or activated charcoal inside and run the freezer empty for several days.
• Check for oily spots: Inspect the evaporator area and rear piping for oily residue, which can indicate a refrigerant leak. If found, do not attempt sealed-system repairs yourself.

Test: After cleaning and deodorizing, re-evaluate odors over several days of normal use.
