Hello MKS team. I recently had an accident where I touched/shorted the part cooling fan wires together. There was black smoke from the board. Now the part cooling fan is always on (partially). Can I fix this and how? Or is there a workaround you can help me with?

Yes this fixed the issue. I happened to burn this component out on a 2nd board and the fix worked there too.
