How to Fix / Troubleshooting
Safety first: If any part is too hot to touch comfortably, stop charging and turn off power.
- Inspect connector: Look for discoloration, melting, or burn marks on the Polestar vehicle connector and inlet. Clean light contamination with a dry cloth; replace the cable if there is visible damage.
- Check cable rating: Ensure the cable is the original Polestar‑supplied unit and rated for the charger’s maximum current.
- Inspect internal terminals: With power off, open the charger and tighten all line and neutral terminals on the input block, contactor, and power module.
- Reduce current: Temporarily lower the maximum current setting and monitor temperatures. If overheating persists, replace the cable assembly or suspect components.
