How to Fix / Troubleshooting
Safety first: Unplug before accessing the control panel.
Steps to restore sound:
- Check settings: Some models allow muting of sounds. Refer to the manual to ensure sound is enabled.
- Access buzzer: Remove the control panel to locate the small round or rectangular buzzer on the PCB.
- Inspect solder joints: Look for cracked or cold solder joints on the buzzer pins. Resolder if necessary.
- Replace buzzer: If the buzzer is physically damaged or still silent, replace it with an equivalent piezo buzzer component.
- Driver circuit: If a new buzzer does not work, the driver transistor or microcontroller output may have failed, requiring main control board replacement.
