What causes Siemens FC18 to have no sound?
- BBarbara RussellSep 8, 2025
If your Siemens Controller has no sound, it could be due to several reasons. First, check if there is voltage. If not, change power lines or main board. Ensure the sound volume is adequately adjusted on the buzzer. If the issue persists, the buzzer itself might be damaged and need replacement. Adjust sound volume of buzzer and change buzzer.
