Display shows a single C or CL and temperatures may not adjust correctly; some models may be stuck in a default setting.

Safety first: Do not remove control panels with power connected. For basic button operations, it is safe to leave the unit plugged in.

• Check for control lock: Look for a small lock icon on the display. Press and hold the Lock or Control button for 3–5 seconds to toggle the lock off.
• Power reset: Unplug the refrigerator (or switch off the breaker) for 5 minutes, then restore power. This can clear minor control glitches.
• Test keypad buttons: Press each button individually. If one button does not respond or feels stuck, the user interface panel may be failing.
• Inspect for moisture: Condensation or spills near the control panel can cause erratic behavior. Wipe the area dry and avoid spraying cleaners directly on the panel.
• Replace user interface (if needed): If the display remains stuck or unresponsive after reset, the UI board may need replacement. This typically involves removing the trim, disconnecting the ribbon cable, and swapping the board.
