Safety first: Unplug the refrigerator before removing the control panel.

Steps:

• Remove panel: Carefully remove the trim and screws holding the control panel. Gently pull it forward.
• Inspect for moisture: Look for condensation or spills behind the panel. Dry thoroughly.
• Check ribbon cable: Reseat the ribbon cable between the keypad and control board.
• Test buttons: With the panel accessible, press each button and observe if the control responds after reassembly.
