Hey there! I noticed my cooling fan stopped working suddenly. I replaced it with a new fan, and it still doesn’t work. I checked out the keypin, and swapped the cooling and the heat fan. It started working just fine. Plugging the heat fan into the PWM port returns no results (I activate cooling fan via Octoprint and have tested it while printing with 100% cooling in the gcode).
Would this be a keypin, motherboard, or firmware issue? Running v4.0.3
