How to Fix / Troubleshooting

Safety: Unplug the unit before removing the control panel.

Steps to restore control panel function:

  • Power reset: Unplug for 5–10 minutes, then plug back in to rule out a temporary software lockup.
  • Inspect panel for moisture: Check for condensation or liquid spills around the control area. Dry the surface thoroughly.
  • Access the control panel: Remove screws securing the top/front trim and gently pull the panel forward.
  • Check ribbon cable: Ensure the keypad or touch panel ribbon cable is fully inserted into the display PCB connector and locked.
  • Look for corrosion: Inspect the PCB and connectors for corrosion or residue. Clean lightly with isopropyl alcohol if minor.
  • Replace keypad/display assembly: If buttons remain unresponsive, replace the control panel or display PCB assembly with a Haier-compatible part.
  • Reassemble and test: Refit the panel and verify that all buttons respond correctly.
