Possible Causes

Failed fan motor, Blocked fan blades, Faulty temperature sensor input, Stuck fan driver transistor on control board

How to Fix / Troubleshooting

Safety first: Turn OFF the breaker before accessing internal components.

  • Inspect fan: Locate the internal fan and check for dust buildup or foreign objects blocking the blades. Clean carefully.
  • Spin test: Gently spin the fan by hand (power OFF). If it feels stiff or seized, replace the fan.
  • Check connector: Ensure the fan’s power connector is firmly seated on the board.

If the fan runs constantly but the charger is otherwise normal, the control circuit or temperature sensor may be faulty. A technician can test and replace the sensor or board as needed.
