Possible Causes
Faulty temperature sensor reading high, Fan control circuit stuck on, Blocked airflow causing real overheating, Fan bearings worn causing noise
How to Fix / Troubleshooting
Safety first: Isolate power before touching the fan or internal components.
Steps:
- 1. Check ambient conditions: Ensure the charger is not installed in a very hot or enclosed space.
- 2. Inspect vents: Clean any dust or debris from ventilation openings.
- 3. Internal inspection: Open the housing and check that the temperature sensor is properly attached to its mounting point (e.g., heat sink).
- 4. Replace fan: If the fan is mechanically noisy, replace the internal cooling fan.
- 5. Sensor/board replacement: If the fan runs at full speed despite normal temperatures, replace the temperature sensor or main control board as required.
Continuous fan operation may be a protective response; verify actual temperatures before assuming a fault.
