Possible Causes
Incorrectly configured control board, Loose UI-to-main-board harness, Failed user interface board, Failed main control board
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing internal components.
- Power reset: Turn off the breaker for 5 minutes, then restore power. Sometimes configuration errors clear after a full reset.
- Check harness connections: Remove the control panel and verify that the multi-pin harness between the user interface board and the main control board is fully seated and not damaged.
- Inspect for moisture: Look for signs of steam or moisture intrusion around the UI board. Dry thoroughly and improve door gasket seal if needed.
- Reconfigure (if applicable): Some Monogram models require configuration codes to be entered on a new control board. Verify that the correct model configuration is set according to the tech sheet.
- Replace faulty board: If wiring is good and configuration is correct but F9E0 persists, replace the user interface board. If that does not resolve it, replace the main electronic control board.
