How to Fix / Troubleshooting

Safety first: Disconnect mains power before removing any covers.

  • Inspect harness: Locate the cable between the display board and main control board. Check for pinched, cut, or loose wires.
  • Reseat connectors: Disconnect and reconnect both ends of the harness to ensure good contact.
  • Check for corrosion: Look for green/white corrosion on connector pins and clean gently if present.
  • Board substitution: If wiring is intact, one of the boards is likely faulty. Replacement of the display board is usually attempted first, followed by the main board if needed.
