How to Fix / Troubleshooting

Safety first: Unplug the dryer before accessing the control panel.

  • Check for lock modes: Ensure the unit is not in demo or display-off mode (refer to manual).
  • Access control panel: Remove the top cover and control panel screws to expose the UI board.
  • Inspect connectors: Reseat the harness between the UI and main board. Look for corrosion or damage.
  • Board replacement: If connections are good and the panel remains blank, test voltages at the UI (qualified person only). Replace the UI board or main control board as indicated by tests.
