Oven light flickers or fails intermittently when the door is opened or during cooking.

Safety first: Switch off power before touching the lamp or holder.

• Reseat lamp: Remove the glass cover and ensure the lamp is screwed in firmly. Replace the lamp if the filament looks damaged.
• Clean contacts: Inspect the lamp holder for corrosion or carbon deposits. Clean gently with a dry cloth or contact cleaner (power off).
• Test door switch: If flicker occurs when moving the door, test and replace the door switch as needed.
• Check wiring: Inspect the lamp circuit wiring for loose spade connectors and secure them.
