Safety: Switch off power; the lamp area may be hot.

• Replace bulb: Unscrew the glass cover and replace the bulb with a Siemens-approved high-temperature oven lamp of the same wattage and base type.
• Check holder: Inspect the lamp holder for burning or loose contacts. Replace if damaged.
• Test wiring: If a new bulb does not work, check continuity from the holder back to the control board or terminal block.
