Possible Causes
Loose UI harness, Failed user interface board, Faulty Wi-Fi/communication module, Main control board communication failure
How to Fix / Troubleshooting
Safety first: Unplug the freezer before removing any control panels.
- Reset electronics: Disconnect power for 5–10 minutes, then restore. Check if CF2 clears.
- Inspect UI connections: Remove the control panel or door display assembly and verify that all ribbon cables and harnesses are fully seated and undamaged.
- Check Wi-Fi module (if equipped): Some Café models have a separate Wi-Fi or communication module. Ensure its connector is secure. If the module is visibly damaged or overheats, replacement may be needed.
- Board replacement: If wiring and modules appear intact and CF2 persists, either the UI board or main control board is likely faulty. Replacement and configuration are typically technician-level tasks.
