Refrigerator has a strong musty or moldy odor that persists after cleaning shelves.

Safety first: Unplug the refrigerator before deep cleaning and accessing the drain pan.

Steps:

• Deep clean interior: Remove all food and shelves. Wash all surfaces with a solution of baking soda and warm water. Dry thoroughly.
• Clean drain pan: Access the drain pan above the compressor from the rear. Remove and wash it with hot, soapy water if possible.
• Flush drain: Use a mild bleach solution to flush the defrost drain tube to kill mold and bacteria.
• Air out: Leave doors open for several hours with the unit unplugged to ventilate.
• Use odor absorbers: Place activated charcoal or baking soda boxes in both compartments.
