Possible Causes
How to Fix / Troubleshooting
Safety first: Immediately turn OFF the breaker and unplug the vehicle. Do not use the charger until inspected.
- 1. Do not restart: Do not attempt to power the charger back on to "see if it still works". This can cause further damage or fire.
- 2. Visual inspection (qualified): After the unit cools, open the housing and look for burnt components, melted plastic, or charred wiring. Identify the source area (input, relay, output terminals, connector).
- 3. Replace damaged parts: Any burnt wiring, terminals, or connectors must be replaced. If the power board or main control board is charred, replace the entire board or charger.
- 4. Check torque on all terminals: After repairs, ensure all high-current connections are tightened to manufacturer specifications.
When to call a professional: Burning smells or smoke indicate serious faults. Have a qualified EVSE technician or electrician perform a full inspection and repair.
