Oven interior light flickers or goes on and off during operation

Safety: Turn off power and allow the oven to cool before touching the lamp.

• Reseat bulb: Remove and reinstall the bulb, ensuring it is firmly seated.
• Inspect holder: Check for signs of arcing or looseness in the lamp holder. Replace if contacts are weak.
• Vibration check: Run the oven and gently tap near the lamp area. If flickering coincides with vibration, the holder or wiring is suspect.

Note: If the lamp is stable when tapped but still flickers randomly, the control board relay may be failing.
