Possible Causes
Vibrating control transformer, Chattering relay due to low voltage, Loose mounting screws on control board or transformer
How to Fix / Troubleshooting
Safety first: Disconnect power before opening the control panel.
- Locate noise source: With the panel removed and power briefly restored (only if safe and qualified), carefully listen to identify whether the noise comes from a transformer or relay.
- Tighten mountings: Turn power off again and tighten screws securing the transformer and control board to reduce vibration.
- Check supply voltage: Have an electrician verify that mains voltage is within the specified range; low or fluctuating voltage can cause relay chatter.
- Component replacement: If the transformer or relay is excessively noisy or overheating, replace the control board or the specific component as appropriate.
