Stepper-driver cooling fan


So I’ve been printing with my K8400 for about a year now, I haven’t had too much trouble. But I recently noticed that my stepper-driver cooling fan doesn’t always turn on or spins rather slow.

Would anyone know what the problem might be and how to possibly solve it?

Kind regards

I don’t think there is any way to repair it.
You should replace it.
