How to Fix / Troubleshooting

Warning: Frequent power cycling under load can stress components.

  • Step 1 – Check supply stability:
    • Have an electrician verify that the breaker, wiring, and panel connections are tight and not overheating.
  • Step 2 – Monitor temperature:
    • Ensure the charger is not installed in a confined, hot space.
    • Check for overtemperature errors in the app.
  • Step 3 – Firmware update:
    • Update charger firmware via the ChargePoint app.
  • Step 4 – Internal inspection (qualified):
    • With power OFF, inspect the main control board for bulging capacitors or burn marks.
  • Step 5 – Replace main board:
    • If reboots continue after ruling out supply and heat, replace the main control board.
