Hyundai Cooling Fan Failure

Charger’s internal fan (if equipped) is noisy or does not run even under high load.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn fan bearings, Dust buildup blocking blades, Fan connector loose on control or power board, Failed fan driver circuit

Safety first: Turn off power at the breaker before opening the charger.

Inspect fan: Check for dust accumulation and gently clean with a soft brush or vacuum.
Spin test: Rotate the fan blades by hand; if stiff or grinding, the fan must be replaced.
Check connector: Ensure the fan’s power connector is firmly seated on the board.
Replace fan: Install a Hyundai‑specified replacement fan with the same voltage and airflow rating.
