Refrigerator has a strong, unpleasant odor even after basic cleaning

Safety first: Unplug the refrigerator before deep cleaning or removing panels.

Steps:

• Empty and clean: Remove all food and shelves. Wash interior surfaces with a solution of baking soda and warm water.
• Clean drain pan: Access the drain pan at the rear bottom. Remove and wash with hot, soapy water. Check for mold or slime.
• Flush drain: Use a mild bleach solution (diluted) or vinegar to flush the defrost drain tube, then rinse with clean water.
• Deodorize: Place open boxes of baking soda or activated charcoal in both compartments for several days.
• Severe cases: If odor persists after thorough cleaning, spoiled material may have penetrated insulation. Professional disassembly or, in extreme cases, replacement of the unit may be required.

Warning: Do not mix bleach and ammonia-based cleaners; toxic fumes can result.
