Touch controls are unresponsive or partially responsive; error indicates keypad or touch panel fault.

Safety first: Turn off power at the breaker. Glass edges can be sharp; handle the control panel carefully.

• 1. Clean the surface: Wipe the touch glass with a soft, dry cloth. Remove any spills or residue that may interfere with capacitive sensing.
• 2. Power reset: After cleaning, leave power off for 5 minutes, then restore and test the panel.
• 3. Check for moisture: If the oven was recently cleaned with excessive water or steam, allow the control area to dry for several hours. Use gentle airflow (no direct heat) to speed drying.
• 4. Inspect connections: Remove the control panel and reseat the ribbon cable between the touch glass and the UI board. Look for corrosion on contacts.
• 5. Replace touch panel or UI board: If specific keys or zones never respond, replace the touch glass assembly. If the entire panel is dead but backlighting works, the UI control board may be defective and should be replaced.
