Bad smell or strong odour inside the refrigerator, even after removing spoiled food.

Deep cleaning:

• Unplug the refrigerator and remove all food. Discard any questionable items.
• Wash all interior surfaces, shelves, and drawers with a solution of baking soda and warm water. Rinse and dry thoroughly.
• Remove and clean the door gaskets, paying attention to folds where debris can accumulate.

Drain and filter:

• Locate and flush the defrost drain with warm water and a mild disinfectant to remove trapped residues.
• If your model has an air filter, replace it according to the manufacturer's instructions.

Odour removal:

• Place an open box of baking soda or activated charcoal inside the fridge to absorb residual odours.
