Possible Causes

Loose communication harness, Damaged data cable, Faulty user interface board, Defective main control board

How to Fix / Troubleshooting

Safety First: Disconnect power before unplugging or reseating any control cables.

  • Inspect harness: Locate the multi-wire harness or ribbon cable between the user interface and main control. Ensure both ends are fully seated and locked.
  • Check for damage: Look for pinched, cut, or abraded sections of the cable. Replace if any conductors appear broken.
  • Clean connectors: Use electronic contact cleaner on the connector pins if oxidation is visible. Allow to dry fully before reconnecting.
  • Board substitution: If wiring is intact, one of the boards is likely faulty. Replace the user interface board first (typically easier), then the main control board if E18 persists.
