Possible Causes

Shorted fan motor drawing excess current, Open fan motor winding, Faulty fan driver on main control board, Damaged fan wiring

Safety first: Unplug the unit before touching any wiring or fan components.

Fan test: Access the interior evaporator fan and attempt to spin the blades by hand. If stiff or seized, the evaporator fan motor is likely bad.
Wiring check: Inspect the fan harness for cuts or melted insulation.
Replace fan motor: If the fan is noisy, seized, or not running, replace the evaporator fan motor.
Control board: If a new fan does not resolve F4, the main control board fan driver may be defective and require replacement.
