Yes, I mean the hot end fan.
I already guessed I killed something on the pcb by accidentally shortening the leads. *blush*
I want to replace the broken part. Can you help me?
Where do I find the part (transistor) on the board?
And what type of transistor do I need?
You mean the hot end fan? if that is always in, check the wiring, if it is actually plugged into the right port on the board. if it is always on, the darlington transistor PWM'ing the fan is maybe dead, and needs replacement. you can kill the transistor by shortening the leads to the fan.
the main electronics fan under the printer is supposed to be always on.
