How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before opening the enclosure.
- Inspect fan operation: With the cover removed and power briefly applied (qualified person only), observe whether the fan starts when the charger is active. Then turn power OFF again.
- Clean fan and vents: With power OFF, use dry compressed air to remove dust from the fan blades and vents.
- Check fan connector: Ensure the fan’s power connector is firmly seated on the main board.
- Replace fan: If the fan is noisy or does not spin freely by hand, replace the cooling fan assembly with an equivalent rated part.
- Monitor temperature: After replacement, monitor the charger for any overtemperature faults during use.
