The oven display works, but the buttons or touch controls do not respond.

Safety first: Disconnect the oven from mains power before removing the control panel.

• Power reset: Turn off the circuit breaker for 5-10 minutes, then restore power. Sometimes the touch controller can lock up, and a power reset will restore operation.
• Inspect control panel: Remove the front control panel assembly. Check for signs of moisture, steam damage, or corrosion on the touch board and its connectors. Dry thoroughly and clean with isopropyl alcohol if lightly contaminated.
• Check ribbon cable: Ensure the flat ribbon cable between the user interface and the main control board is fully seated and not cracked or torn. Reseat both ends. Replace the cable if it is damaged.
• Test keypad: On models with membrane keypads, test the continuity of individual keys if possible. If multiple keys fail or the touch glass is unresponsive, replace the complete user interface module or the glass touch panel.
• Main board: If a known-good user interface (UI) still does not respond, the main control board may not be correctly reading the keypad signals and should be replaced.
