Possible Causes

Partially clogged defrost drain, Misaligned drain trough, Excessive frost from door left open

How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before removing interior panels.

Steps:

  • Remove shelves and drawers: Access the rear interior panel of the fresh food or freezer section (depending on model).
  • Inspect drain trough: Look for standing water or ice in the trough below the evaporator.
  • Clear blockage: Use warm water to melt ice and a flexible brush or pipe cleaner to clear the drain hole.
  • Check for alignment: Ensure the trough is properly seated and sloped toward the drain hole.

Corrective action: After clearing the drain, dry the area and reassemble. Monitor for recurrence; if frequent, have a technician inspect for underlying insulation or design issues.
