Interior light stays on when the door is closed, causing heat and possible melting near the light area.

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

Steps:

• Confirm symptom: Close the door slowly and look through the gasket gap to see if the light turns off. If it stays on, the switch is not being actuated.
• Inspect door alignment: Check that the door closes evenly and that hinges are not sagging. Adjust the door or leveling feet if needed.
• Test door switch: Locate the door switch (usually in the frame). Press it by hand; the light should turn off. If not, the switch may be faulty.
• Replace switch: Pry out or unscrew the switch, disconnect the wires, and install a new Etna door switch. Ensure it protrudes enough to be pressed by the door.
• Re-test: Restore power and verify that the light now turns off when the door is closed.
