How to Fix / Troubleshooting
Safety: Do not attempt board‑level repairs; there are no user‑serviceable components inside.
- Check external power: Verify the breaker is on and that correct line voltage is present at the Wall Connector input terminals.
- Inspect for surge damage: Look for burn marks or melted plastic around the entry point and board (qualified person only).
- Power cycle: Turn off the breaker for several minutes, then restore power and observe if the unit boots normally.
- Surge protection: If surges are suspected, consider installing a whole‑home surge protector to protect replacement equipment.
- Replace unit: Persistent CP_a015 indicates a failed internal power supply; the Wall Connector must be replaced.
