Freezer interior temperature too warm only at the top; bottom baskets stay frozen.

Safety first: Unplug the freezer before removing panels or clearing ice.

Steps to improve top compartment cooling:

• Check fan operation: Ensure the evaporator fan runs at full speed when the compressor is on. Replace the evaporator fan motor if weak or intermittent.
• Inspect air vents: Locate supply and return vents in the liner and clear any ice or packaging blocking them.
• Reorganize contents: Avoid stacking items directly in front of vents or packing the top shelf too tightly.
• Defrost if needed: If ice is blocking airflow channels, perform a manual defrost to restore proper circulation.

Note: Upright freezers rely heavily on unobstructed airflow to maintain even temperatures.
