Freezer alarm beeping but temperature appears normal; no error code displayed.

Safety first: Do not ignore alarms until you verify temperature with a separate thermometer.

• Verify temperature: Place an accurate thermometer inside your Fagor freezer and confirm it maintains around -18°C.
• Check door switch: Wiggle the door and observe if the alarm triggers. Replace a loose or intermittent door switch.
• Silence alarm: Use the alarm reset button to silence. If it does not recur and temperature is stable, it may have been a power interruption alarm.
• Sensor and board: If false alarms are frequent, consider replacing the cabinet sensor and, if needed, the control board.
