Possible Causes
Loose or damaged harness between UI and main PCB, Faulty user interface board, Faulty main control board, Electrical noise or surge damage
How to Fix / Troubleshooting
Safety first: Disconnect power before removing any panels.
- Reseat connectors: Access the control panel and main board. Disconnect and reconnect the multi-pin harness between them, ensuring a firm fit.
- Inspect harness: Look for pinched, cut, or burnt wires along the path between boards. Replace the harness if damaged.
- Check for signs of surge damage: Burn marks or blown components on either board suggest replacement is necessary.
- Board substitution: If wiring is intact, one of the boards is likely defective. Replace the user interface board first (often easier), then the main control if the error persists.
