Oven interior light does not work, but the oven heats normally.

Safety first: Switch off power before replacing the bulb to avoid electric shock.

• Replace bulb: Remove the glass cover over the lamp and replace the bulb with a high-temperature oven bulb of the correct type and wattage.
• Inspect lamp holder: Check for signs of burning or looseness. Replace the lamp holder if contacts are damaged.
• Door switch: If the lamp still does not work, test the oven door switch for continuity when pressed. Replace if faulty.
• Wiring check: Inspect wiring from the control board to the lamp holder for breaks or loose connectors. Repair as needed.
