Possible Causes
How to Fix / Troubleshooting
Safety first: Turn OFF the breaker before any physical inspection.
Steps:
- Check for vibration sources: Ensure the charger is not mounted on a thin, vibrating wall panel.
- Observe pattern: Note whether flickering coincides with contactor clicks or other events; share this with a technician.
Because the issue is internal to the GM electronics, homeowner repair is not recommended. If flickering is frequent, have the charger inspected or replaced to avoid unexpected charging interruptions.
