Possible Causes
Loose user interface connector, Moisture in control panel, Failing low-voltage power supply on main board, Faulty display module
How to Fix / Troubleshooting
Safety first: Turn off power before removing the control panel.
- 1. Inspect for moisture: Remove the inner door panel and check for signs of water ingress around the control panel. Dry thoroughly if damp.
- 2. Check connectors: Reseat the ribbon cable and connectors between the user interface and main board.
- 3. Power supply check: If you are qualified, measure the low-voltage outputs from the main board. Fluctuating voltages indicate a failing board.
- 4. Replace faulty module: If the display itself is defective, replace the user interface board. If the supply is unstable, replace the electronic control board.
