Clock and timer functions work, but oven will not start when temperature and mode are selected.

Safety first: No internal work is initially required; start with control settings and door checks.

Step-by-step checks:

• Check display indicators: Ensure that delayed start or timer icons are not active. Cancel any active timers.
• Verify door closed: Confirm the door is fully closed and the door switch is engaging.
• Disable child lock: If a lock icon is present, disable the control lock per the user manual.
• Test start button: Try pressing the start key firmly. If it feels different or does not beep, the keypad may be faulty.

When to replace parts: If settings and door are correct but the oven will not start, replace the door switch if it does not signal closed, or the touch keypad assembly if the start key is defective.
