Oven interior light does not turn on when door is opened or when light button is pressed.

Safety first: Turn off power before replacing the bulb or accessing wiring.

• Replace bulb: Remove the glass light cover inside the oven and replace the bulb with an LG-approved high-temperature oven bulb of the same wattage.
• Test door switch: If the light still does not work, test the door switch for continuity when the door is open/closed. Replace if faulty.
• Check socket and wiring: Inspect the light socket and wiring for burns or loose connections. Repair as needed.
• Control board: If the switch and bulb are good, the light relay on the control board may be defective and require board replacement.
