Display shows 'F' or a flashing snowflake; freezer runs continuously and may form excessive frost.

Note: This is often a user-selected mode.

• Disable super freeze: Press the Super Freeze or similar key once to turn off the function. The indicator should go out.
• Power reset: If the mode will not cancel, unplug the freezer for 5 minutes and reconnect. Check if the indicator clears.
• Check button operation: If the super freeze button is physically stuck or unresponsive, clean around it and test again. If still faulty, the UI PCB may need replacement.
• Monitor frost: If frost continues to build rapidly even with super freeze off, there may be a defrost or door sealing issue that needs further diagnosis.
