Interior light (if equipped) does not turn on during cooking.

Safety first: Unplug and cool the unit before accessing the light.

• Check settings: Some models allow turning the light on/off manually; verify it is enabled.
• Access light assembly: Remove the interior light cover and inspect the cavity light (bulb or LED module).
• Replace lamp/module: If the filament is broken or the LED is visibly damaged, replace with the correct Breville part.
• Inspect wiring: Reseat the light connector and check for damaged wires.
• Control board: If a new light does not work, the main control board light driver may be faulty.
