Oven light and display work but oven will not start any cooking cycle.

Safety: Disconnect power before accessing internal components.

• Check control lock: Look for a lock icon on the display. Press and hold the designated key (often "Control Lock" or a specific key for 3–5 seconds) to unlock.
• Verify door closed: Ensure the door is fully closed and the latch engages. If the door switch is faulty, the oven may not start.
• Check thermal fuse: Access the rear of the range and locate the oven thermal fuse. Test for continuity and replace if open.
• Control board: If fuses and switches are good, the main control relay may have failed and the control board may need replacement.
