Possible Causes
Internal relay or contactor test failure, Failed self‑test of GFCI/RCD, Faulty power module diagnostics, Corrupted self‑test parameters
How to Fix / Troubleshooting
Safety first: Do not attempt to bypass self‑test functions. Turn off power before internal inspection.
- Power cycle: Turn off the breaker for 2–3 minutes, then restore power and observe the startup sequence. Note any unusual sounds or smells.
- Listen for relays/contactors: During self‑test, you should hear one or more clicks. If there are no clicks or continuous chattering, inspect the contactor and relays for damage.
- Check internal wiring: Ensure all plug‑in connectors between the main control board, power module, and safety devices are fully seated.
- Service diagnostics: Many self‑test failures require specialized tools. Contact an authorized Polestar service provider to run extended diagnostics and replace the power module or control board as indicated.
