Control panel buttons or touch fields do not respond, but the display is lit and shows the time.

Safety first: Ensure hands are dry and the panel is clean before testing.

Step-by-step checks:

• Disable child lock: Follow the user manual to deactivate the child safety lock (often by holding a specific key combination).
• Clean panel: Wipe the glass or plastic surface with a soft, dry cloth to remove grease and moisture.
• Power reset: Turn off the oven at the breaker for 2–3 minutes, then restore power and test again.
• Inspect connections: If still unresponsive, disconnect power, remove the control panel, and reseat the ribbon cable between the touch panel and PCB.

When to call a technician: If only some keys fail or the panel remains dead, the touch panel or UI board likely needs replacement.
