Possible Causes

Safety first: Unplug the freezer before removing any control covers.

Check connectors: Remove the control panel and verify that all plugs between the display and main board are fully seated.
Inspect harness: Look for pinched or cut wires in the harness running through the cabinet.
Replace display PCB: If wiring is intact, replace the Fagor display/user interface board.
Main board: If a new display does not resolve F1, the main control board may be defective and should be replaced.
