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

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

• Test door switch: Press the switch manually and listen for a click. If the light does not go off, test the switch for continuity and replace the door switch if faulty.
• Check door alignment: Ensure the door properly contacts and depresses the switch when closed. Adjust hinges if necessary.
• Temporary mitigation: Remove the light bulb or disconnect the LED module until the fault is repaired to prevent warming.

Note: If the switch is good but the light remains on, the control board’s light relay may be stuck and require professional replacement.
