How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
- Inspect for moisture: Look for signs of liquid ingress around the control panel. Allow to dry thoroughly if recently exposed to moisture.
- Check ribbon cable: Reseat the cable between the user interface and main board. Inspect for cracks or corrosion.
- Test buttons: If only certain keys fail consistently, the keypad membrane or touch panel is likely worn and should be replaced.
- Replace UI assembly: Install a new Teka control panel assembly if individual button repair is not possible.
