All segments on the display show 88 88 or 88 88 flashing; unit may be in diagnostic or error mode.

Safety: Disconnect power before removing control panels.

• Power reset: Unplug the freezer for 5 minutes, then plug back in. Many Samsung models will clear a temporary 88 88 display after a reset.
• Button reset: Press and hold the Power Freeze and Power Cool buttons simultaneously for 10 seconds to exit diagnostic mode (if applicable to your model).
• Inspect display connections: If the issue persists, remove the front display/control panel and check that the ribbon cable and connectors are fully seated and not corroded.
• PCB diagnosis: If connections are good and 88 88 remains, either the display PCB or main PCB may be faulty. Replacement typically requires a technician to avoid damaging the cabinet or wiring.
