How to Fix / Troubleshooting

Safety first: Unplug the cooker before opening any covers. This procedure may void warranty; check your warranty terms.

  • Power reset: Leave the unit unplugged for 10 minutes, then plug back in and test. Sometimes transient faults clear with a reset.
  • Inspect control panel connection: If you are experienced with appliance repair, remove the front panel screws and gently access the ribbon cable between the display board and main PCB. Reseat both ends carefully.
  • Check for moisture: Look for signs of liquid ingress behind the control panel. If present, dry thoroughly and do not power until fully dry.
  • If E9 persists: The main PCB or display board likely needs replacement using Midea-compatible parts.
