Strong unpleasant odor inside the refrigerator even after removing spoiled food.

Safety first: Unplug the refrigerator before deep cleaning and avoid harsh chemicals that can damage plastics.

Steps:

• Empty and clean interior: Remove all food and shelves. Wash all surfaces with a solution of warm water and baking soda or mild detergent.
• Clean gaskets: Gently pull back the door gaskets and clean inside the folds where spills can accumulate.
• Check drain pan: Remove the rear lower cover and slide out or inspect the drain pan. Clean it thoroughly with warm soapy water and dry before reinstalling.
• Ventilate: Leave doors open for several hours with the unit unplugged to air out the interior.
• Use odor absorbers: Place activated charcoal or baking soda boxes inside once the unit is back in service to absorb residual odors.
