3DP-10-4A - Extruder Not working

Hey all,

This is my first post, I have been using an ANET 3D printer for a while and now I have a 3DP-10-4A printer from work that wasn’t working.

I have fixed a few things, but the last thing that doesn’t seem to work is the extruder/LED/

The hot-end is getting hot and as soon as you switch the printer on the Extruder stepper motor is getting hot. Is there any check I can do to find the root cause, is there any spare parts i can purchase and do people think it’s the extruder or the PCB?
