How to Fix / Troubleshooting

Safety: Turn off power at the breaker before accessing the control board.

  • Power reset: Turn the breaker off for 5 minutes, then restore power. Attempt to run a short cycle to see if the code clears.
  • Check for stuck buttons: Inspect the control panel for stuck or unresponsive keys that might confuse the control. Clean around the buttons.
  • Inspect control board: Remove the inner door panel to access the main control. Look for burn marks, corrosion, or water intrusion on the board and connectors.
  • Reconfigure if applicable: Some GE models allow configuration of features via service mode. If recently replaced, ensure the board is configured for the correct model per service documentation.
  • Replace control board: If C9 persists after reset and inspection, replace the main control board with the correct GE part number for your model.
