Display shows lights but segments are missing or unreadable.

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

Steps to restore display:

• Inspect panel: Remove the front control panel and check the display board for corrosion or moisture.
• Reseat ribbon cable: Disconnect and reconnect the ribbon cable between the display and main board.
• Dry moisture: If condensation is present, dry the area thoroughly and improve ventilation.
• Replace display: If segments remain missing, replace the display module or control panel assembly.

When to call a technician: If a new display does not fix the issue, the main board’s display driver may be faulty and needs professional replacement.
