How do I fix hotend fan speed abnormal / stopped?

1
Stop printing immediately. The hotend fan cools the heatbreak — without it, heat creeps up causing jams and potential PTFE damage.
2
Check for filament strands or debris in the fan blades. Clear any obstructions and verify the fan rotates freely.
3
If the fan spins freely but the error persists: reseat the cable connection. If it continues, the fan needs replacement.

Pro tip: A failing hotend fan leads to heat creep. Resolve this hardware issue before adjusting print settings.
