How to Fix / Troubleshooting
Warning: Overheating can lead to melting or fire. Stop using the charger until inspected.
- Step 1 – Stop charging:
- Unplug the vehicle and allow components to cool.
- Step 2 – Visual inspection:
- Look for discoloration, cracks, or deformation on the J1772 handle and cable.
- Inspect the vehicle inlet for similar damage.
- Step 3 – Reduce current:
- In the ChargePoint app, temporarily lower the maximum current setting (e.g., from 40 A to 24 A) and test again.
- If heating is reduced, the connector may be marginal but still needs replacement.
- Step 4 – Replace cable assembly:
- If any damage is visible or overheating persists, replace the EVSE output cable & J1772 connector assembly.
- Step 5 – Check vehicle inlet:
- If the vehicle inlet is damaged, have it inspected and replaced by the vehicle manufacturer.
