How to Fix / Troubleshooting
Safety first: Unplug before opening the housing.
- Confirm source: Listen carefully to locate whether the sound comes from the base, side, or lid.
- Inspect control board (advanced): Remove the bottom or side cover and look for loose coils or transformers. Gently press on them (unplugged) to see if they are loose.
- Tighten mounts: Ensure the control board is firmly screwed down and any large components are not rattling.
Mild coil whine is often harmless. If the noise is very loud or accompanied by burning smell or malfunction, discontinue use and have the board inspected or replaced.
