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

Safety: Unplug the refrigerator before working on the light or door switch. The light socket carries mains voltage.

Steps:

• 1. Check switch operation: Press the door switch manually and see if the light turns off (with power briefly connected). If not, unplug and remove the switch for testing.
• 2. Test switch: Use a multimeter to check continuity. Replace the switch if it remains closed regardless of position.
• 3. Door alignment: Ensure the door fully depresses the switch when closed. Adjust hinges if necessary.
• 4. Control board: If the switch is good but the light remains on, the control board may be faulty and require replacement.

Warning: A light that stays on can overheat plastic parts and is a fire risk; address immediately.
