How to Fix / Troubleshooting

Safety: Unplug the refrigerator before deep cleaning and removing shelves.

  • 1. Remove all food: Discard expired items. Place remaining food in a cooler.
  • 2. Clean interior surfaces: Wash all shelves, drawers, and walls with a solution of warm water and baking soda or mild detergent. Pay attention to corners and under drawers.
  • 3. Clean gaskets: Wipe door gaskets thoroughly, pulling them back gently to clean hidden areas.
  • 4. Flush defrost drain: Access the drain in the freezer and flush with warm water to remove trapped debris that can cause odor.
  • 5. Air out the unit: Leave doors open for several hours (with power off) to allow odors to dissipate.
