Steps If the Leak Source Is Unknown

  1. Open the refrigerator door and inspect the back wall for condensation, frost, or ice buildup on the back wall. See also, Ice Forming on Back Wall of Refrigerator.
  2. Remove the crisper drawer and crisper shelf assembly. If equipped, remove all lower storage drawers to inspect for condensation, water, or ice near, behind, or underneath the drawer(s).
    • Food debris, standing water, or ice buildup in the drain trough or drain tube along the back wall may cause standing water on the floor. The drain tube may be clogged.
    • This can cause water to sit up against the door gasket, causing the water to drip from the gasket on to the floor when the door is opened.
  3. Clear any standing water or ice.
  4. Clean the drain tube if possible.
  5. If these troubleshooting steps do not resolve the issue, service is necessary to expertly diagnose and repair the product. Contact Factory Certified Service to schedule an appointment for repair.
