Thick sheet of ice forming on the freezer floor.

Safety first: Unplug the freezer and remove food from the bottom area.

• Remove ice: Use a plastic scraper to remove loose ice from the floor. Do not use sharp tools that can puncture the liner.
• Access drain trough: Remove the inner rear panel to expose the evaporator and drain trough at the bottom.
• Clear drain: Pour warm water into the drain trough and hole until it flows freely into the drain pan. Use a flexible plastic tube or pipe cleaner to clear obstructions.
• Check level: Ensure the freezer is level front-to-back so water flows toward the drain. Adjust leveling feet as needed.
• Inspect trough and tube: Look for cracks or misalignment that could cause water to spill into the cabinet. Replace damaged parts.

After repair, monitor for new ice formation. If the problem recurs, the drain tube may be freezing due to insulation issues that require professional repair.
