Unpleasant or rotten smell coming from inside the refrigerator or freezer.

Safety warning: Unplug the refrigerator before deep cleaning, especially near electrical components.

Steps:

• 1. Remove all food: Discard any spoiled items. Temporarily store good food in a cool box.
• 2. Clean interior: Wash all shelves, drawers, and interior surfaces with a solution of baking soda and warm water. Rinse and dry thoroughly.
• 3. Clean drain: Flush the fridge drain hole and channel with warm water and a mild disinfectant to remove biofilm.
• 4. Check drip tray: Access the drip tray near the compressor and clean out any stagnant water or mold.
• 5. Improve airflow: Ensure vents are not blocked by food packages.

Note: Leaving an open box of baking soda inside can help absorb residual odors.
