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

Safety first: Unplug before accessing the light assembly.

Steps:

• 1. Confirm feature: Verify that your Bosch model actually includes an interior light and that it is supposed to be on during cooking.
• 2. Access light: Remove the inner cover or lens over the cavity light.
• 3. Check connections: Ensure the light connector is firmly attached.
• 4. Replace light: If the LED module or bulb is visibly damaged or tests open, replace it with the correct Bosch part.
• 5. Driver circuit: If the light is good but not receiving power, the control board's light driver may have failed; board replacement is required.
