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:
