Oven light, fan, and display work but oven will not start heating when Start is pressed

Safety first: No internal access is needed for initial checks. If you open the unit, disconnect power first.

• Check child lock: Look for a key or lock symbol on the display. Disable the lock by holding the indicated button combination (refer to the user manual).
• Reset timer settings: Cancel any delayed start or programmed end time. Set a simple manual mode (e.g. conventional heat at 180°C) and press Start.
• Power reset: Turn off power at the breaker for 5–10 minutes, then restore and test again.
• Test Start control: If the Start button or knob does not register, the user interface may be faulty. Replace the UI panel or keypad assembly.
