Freezer interior warm, but thick sheet of ice on the floor of the compartment or under lower basket.

Safety first: Unplug the freezer. Use towels to absorb water and prevent slipping.

Steps to clear a blocked drain:

• Remove interior panels: Take out the lower baskets and interior rear panel to access the evaporator and drain trough.
• Locate drain hole: Find the small hole or channel at the bottom center of the evaporator tray.
• Defrost ice: Use warm (not boiling) water in a turkey baster or squeeze bottle to melt ice in the drain hole. Repeat until water flows freely.
• Clear blockage: Gently insert a flexible plastic tube or pipe cleaner into the drain to dislodge debris. Do not use rigid metal that could puncture the tube.
• Check exterior drain end: At the back of the freezer, locate the end of the drain tube above the drain pan. Ensure it is not blocked or kinked.
• Reassemble: Dry the area, reinstall panels, and restore power.

Tip: Periodically cleaning the drain area can prevent future ice buildup.
