My extruder temp is stuck at 103 degrees! How do I fix this problem? I put the extruder thermistor in to the bed thermistor port and it reads fine so I can’t figure out what to do! Any help would be appreciated.
Could be your thermistor anyway, or the MOSFET on your mainboard. Check also that the cable are still properly wired and the flat ribbon cable in the back of the printer. Very often, it moves a little in its socket.
