Oven display and fan work but interior light does not turn on

Safety: Switch off power and allow the oven to cool before changing the lamp.

• Replace bulb: Remove the glass lamp cover inside the cavity (usually by twisting) and replace the bulb with the exact type and wattage specified by Gaggenau.
• Inspect lamp holder: Check for heat damage or corrosion on the lamp contacts. Replace the holder if contacts are burnt or loose.
• Test lamp function: After replacing the bulb, restore power and test. If it still does not light, the issue may be in the wiring or control board.

Note: If multiple bulbs fail prematurely, check for overheating or incorrect bulb type.
