Refrigerator has a strong musty or sour odor inside.

Safety: Unplug the refrigerator before deep cleaning. Use non-abrasive cleaners and ensure good ventilation.

Steps:

• 1. Remove all food: Discard spoiled items. Temporarily store good food in a cooler.
• 2. Clean interior: Wash shelves, drawers, and walls with a solution of baking soda and warm water. Rinse and dry thoroughly.
• 3. Clean gaskets: Wipe door gaskets with mild detergent and water. Dry completely to prevent mold.
• 4. Drain pan: Access the rear and remove the drain pan above the compressor if possible. Clean it with hot soapy water and reinstall.
• 5. Deodorize: Place an open box of baking soda or activated charcoal inside to absorb residual odors.
