How to Fix / Troubleshooting

Disconnect power before working on lights or fans.

E8 can indicate a fault in one of the accessory circuits controlled by the main board.

  • 1. Observe which accessory fails:
    • Check if the interior LED light, decorative fan, or other accessory is not working or flickering.
  • 2. Inspect LED light module:
    • Remove the light cover inside the cabinet.
    • Check for burn marks or moisture inside the light housing.
  • 3. Disconnect suspect accessory:
    • Unplug the LED light or accessory from its connector on the control board.
    • Power the unit back on briefly to see if E8 clears (do not touch exposed connectors).
  • 4. Replace failed accessory:
    • If E8 clears when the accessory is disconnected, replace the Lanbo LED light module or other failed component.
  • 5. If E8 persists with all accessories disconnected:
    • The main control board accessory driver may be shorted and require replacement.
