Possible Causes

Seized fan motor bearings, Obstruction in fan blades, Disconnected fan wiring, Failed fan driver on PCB

Safety first: Unplug before accessing the fan.

Check for obstructions: Remove the cover and inspect the fan for foreign objects or broken plastic pieces blocking movement.
Spin test: Gently spin the fan by hand. If it is stiff or does not spin freely, the motor is likely failing and should be replaced.
Verify wiring: Ensure the fan’s connector is firmly attached to the control PCB and wires are intact.
Replace motor: Install a compatible replacement fan motor assembly if the original is seized or open-circuit.
