Control panel unresponsive; buttons do not work or only some functions respond.

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

Step 1 – Check for control lock:

• Look for a lock icon on the display.
• Press and hold the designated lock/unlock button combination (see user manual) for 3–5 seconds to toggle.

Step 2 – Power reset:

• Unplug the unit for 5 minutes and restore power.

Step 3 – Inspect UI connections:

• Remove the control panel bezel.
• Reseat the ribbon cable or harness to the UI board.

Step 4 – Replace UI board if needed:

• If buttons remain unresponsive, replace the user interface board.

When to call a technician: If the main control board is also suspect or if you are not comfortable with panel removal, contact a professional.
