How to Fix / Troubleshooting

Safety first: This is an emergency. Risk of fire and electric shock is high.

Immediate actions:

  • Switch off power: Turn OFF the dedicated EV charger breaker and, if safe, the main switch for the property.
  • Do not touch the charger: Allow it to cool. Do not attempt to open the enclosure while hot or smoking.
  • Call a professional: Contact a qualified electrician or Hager service immediately. If there is active fire, call emergency services.
  • Technician repair: A professional must open the unit, identify and replace any burnt components (contactor, terminals, boards), and verify cable sizing and protection. In many cases, full charger replacement is recommended.
