Possible Causes
Loose transformer or inductor on main board, Vibrating heating element bracket, Resonance in metal housing panels
How to Fix / Troubleshooting
Safety: Unplug the unit before opening the base. Avoid touching live circuits.
- Identify noise source: With the base removed and the unit reassembled enough for safe operation, briefly power on (only if you are experienced and can do so safely) to localize the noise to the main board or heating assembly.
- Secure components: Once unplugged again, apply non-conductive silicone or hot-melt glue to secure vibrating inductors or transformers on the main board.
- Tighten brackets: Tighten screws holding the heating element and internal metal panels to reduce resonance.
- Re-test: Reassemble fully and test. If the noise persists but the unit functions normally, it may be a harmless annoyance rather than a fault.
