Interior light stays on even when the door is closed, causing warming near the top.

Safety first: Unplug the freezer before adjusting or replacing the door switch.

• Step 1 – Confirm light behavior: Look through the door gasket gap in a dark room to see if the light remains on when the door is closed.
• Step 2 – Check door alignment: Ensure the door is level and closes firmly. Adjust hinges or leveling legs if needed.
• Step 3 – Test door switch: Press the switch by hand; the light should turn off. If it does not, replace the switch.
• Step 4 – Replace switch: Remove the old switch from the liner, transfer wires to the new switch, and snap it into place.
