Ice buildup on the freezer floor or under the bottom basket.

Safety: Unplug the refrigerator before removing panels or chipping ice.

Steps:

• Remove ice: Take out the bottom freezer basket and carefully remove large chunks of ice by hand. Do not use sharp tools that can damage the liner.
• Access drain: Remove the rear freezer panel and locate the drain trough and hole.
• Flush drain: Use warm water to melt any ice in the drain and verify that water flows into the drain pan underneath.
• Check gasket: Inspect the freezer door gasket for gaps that allow moist air in. Repair or replace as needed.
• Optional: Some technicians install a small copper or aluminum wire from the defrost heater into the drain hole to conduct heat and reduce refreezing; this should be done carefully to avoid damage.
