Refrigerator interior light stays on when door is closed, causing heat and possible melting near light.

Safety first: Unplug the refrigerator before working on the light or switch. The light socket can be hot.

Steps:

• 1. Confirm light behavior: Press the door switch manually with the door open. The light should turn off. If it stays on, the switch is faulty.
• 2. Remove switch: Pry the switch out of the liner carefully and disconnect the wires.
• 3. Test switch: Use a multimeter to check continuity while pressing and releasing the switch. Replace if it does not change state.
• 4. Install new switch: Connect wires to the new OEM door switch and snap it into place.
• 5. Check door alignment: Ensure the door fully depresses the switch when closed.
