Possible Causes

Tripped or faulty circuit breaker feeding Volvo charger, Loose or disconnected supply wiring at charger input, Failed internal low‑voltage power supply module, Blown internal fuse on control board

How to Fix / Troubleshooting

Safety first: Do not assume the charger is safe just because it appears off. Verify power is off at the breaker before opening the unit.

  • Check breaker: Inspect the dedicated breaker in your panel. Reset if tripped. If it trips again immediately, stop and call an electrician.
  • Verify supply voltage (electrician): Have an electrician confirm voltage is present at the charger input terminals.
  • Inspect internal fuse: With power OFF and cover removed, locate any internal fuses on the control or power supply board. Replace only with identical type and rating if blown, and investigate cause.
  • Check low‑voltage supply: If mains is present but no LEDs light, the internal power supply module may have failed and will need replacement.

If you are not trained to work on mains circuits, contact a licensed electrician or Volvo‑authorized installer for diagnosis and repair.
