How to Fix / Troubleshooting
Safety first: Immediately turn OFF the breaker. If you see flames or heavy smoke, evacuate and call emergency services. Do not attempt to open the unit while it is hot or energized.
- Do not reset or reuse: A burning smell or smoke indicates serious internal damage. The charger must remain off until inspected.
- After cooling: A qualified technician can open the unit to identify the failed component (e.g., power module, surge board, wiring).
- Replace damaged assemblies: Any burned boards, melted wiring, or discolored connectors must be replaced. Often, replacing the entire charger is the safest option.
- Investigate cause: Have an electrician verify that the supply circuit is correctly sized and wired to prevent recurrence.
