• Loose or damaged electrical connection to the fan motor.
• Power supply issue to the fan motor.

Click steps to track your progress.

1. 1

   Visually inspect the PCB cooling fan for any physical damage, dust accumulation, or obstructions preventing its rotation.

2. 2

   Check the electrical connections to the fan motor for looseness, damage, or corrosion.

3. 3

   Verify the fan's operation during power-on; listen for unusual noises or a complete lack of movement.

4. 4

   If the fan is confirmed to be faulty or non-operational, replace the PCB cooling fan unit.

5. 5

   Ensure that the replacement fan matches the specifications (voltage, airflow, size) of the original.
