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

Safety first: Turn off power at the breaker before replacing bulbs or sockets.

• Replace bulb: Remove the glass light cover inside the oven, unscrew the bulb, and replace it with the correct high-temperature oven bulb specified by LG Studio.
• Check socket: Inspect the socket for discoloration or burning. If damaged, replace the socket assembly.
• Test door switch: If the light does not come on when the door opens, the door switch may be faulty. Replace the switch if it does not click or show continuity when actuated.
• If bulb, socket, and switch are good: The main PCB light relay may have failed and the board may need replacement.

Note: Do not use standard household bulbs; they cannot withstand oven temperatures.
