Troubleshooting

Symptom	Possible Cause	Corrective Action
No power output	AC input/switch	Check wall outlet; ensure power switch is on; verify connections.
System shuts down	Overload/overheat	Reduce system load; check ventilation; clean dust from fan.
Fan not spinning	Temperature/fault	Fan may not spin at low loads; check if hot; replace if faulty.
Intermittent operation	Loose connections	Check all power connections; reseat connectors.
Unusual noise	Fan bearing/dust	Clean fan; replace if noise persists.

Reset: Unplug from AC power for 30 seconds, then reconnect.
