Possible Causes

Clogged drain hole, Blocked or kinked drain tube, Cracked drain pan, Excessive door condensation

How to Fix / Troubleshooting

Safety: Unplug the unit before working inside the cabinet or behind the rear panel.

Steps:

  • Locate drain hole: Inside the cabinet, find the small drain hole or channel at the rear or bottom where defrost water should exit.
  • Clear blockage: Use a soft pipe cleaner, cotton swab, or flexible plastic rod to gently clear any debris or mold from the drain hole.
  • Flush with warm water: Using a turkey baster or syringe, flush warm (not boiling) water through the drain to ensure it flows freely to the rear drain pan.
  • Inspect rear drain tube and pan: Remove the rear panel and verify the drain tube is properly connected and not kinked. Check the drain pan above the compressor for cracks or overflow.
  • Correct door issues: Ensure the door gasket seals properly to minimize excess condensation.

After cleaning: Dry any standing water, reassemble, and monitor for recurrence over several days.
