IceKing ice maker's display is lit but completely blank or shows garbled characters.

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

Step-by-step checks:

• 1. Reseat cables: Remove the front panel and reseat the display ribbon cable at both ends.
• 2. Dry moisture: If condensation is present, allow the panel to dry completely.
• 3. Inspect display board: Look for corrosion or burn marks. Replace the display PCB if damaged.
• 4. Test: Reassemble and power on. If the display remains blank but the unit runs, the display board is likely faulty.

When to call a technician: If replacing the display does not resolve the issue, the main control PCB may be at fault and should be checked professionally.
