The freezer displays the temperature but does not respond to button presses or setting changes.

Safety: No internal work is required for initial checks.

Steps:

• 1. Check for a lock function: Many IKEA freezers have a key or lock icon. Press and hold the indicated button combination (often 3–5 seconds) to unlock.
• 2. Power reset: Unplug the appliance for 5 minutes and then reconnect it.
• 3. Test each button: If some buttons work and others do not, the keypad is likely faulty. Replace the user interface board.
