How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before removing the control panel.
Steps:
- 1. Clean surface: Wipe the control panel with a soft, slightly damp cloth to remove grease or residue that may affect touch sensitivity.
- 2. Access UI board: Remove the trim and screws holding the control panel. Carefully pull it forward.
- 3. Check ribbon cable: Ensure the ribbon cable between the keypad and UI board is fully seated and not damaged.
- 4. Inspect for moisture: Dry any condensation or spills behind the panel. Allow the board to dry completely before reassembly.
- 5. Replace UI board: If buttons remain unresponsive, replace the user interface PCB with the correct Siemens part.
Tip: Avoid spraying cleaners directly onto the control panel; spray onto a cloth instead.
