Timer or alarm beeper is very quiet or does not sound at all.

Safety first: Disconnect mains power before accessing the control panel.

Steps to fix:

• Check settings: Some OBH Nordica ovens allow volume adjustment or muting of the buzzer. Verify settings in the user menu.
• Inspect buzzer: Remove the control panel and locate the small buzzer on the PCB. Check for physical damage or loose solder joints.
• Reseat connectors: If the buzzer is on a separate small board, reseat its connector.
• Replace control board or buzzer module: If the buzzer is defective and not separately replaceable, replace the control board or buzzer module with an OBH Nordica-compatible part.
• Test: Reassemble, restore power, and test the timer alarm.
