Interior light stays on when the freezer door is closed, causing heat and poor cooling near the top.

Safety: Unplug the freezer before working on the door switch or light assembly.

• Check light behavior: Press the door switch manually with the door open. The light should turn off. If not, the switch is likely faulty.
• Inspect switch: Remove the switch from the liner and check for broken tabs or burnt contacts.
• Test continuity: Use a multimeter to test the switch operation. Replace if it does not open/close properly.
• Verify door alignment: Ensure the door fully depresses the switch when closed.

Replacing a faulty door switch typically resolves the light staying on and associated warming.
