Hi, I am sorry if this is trivial stuff but I am new to this.

I inherited this printer at work and this morning got back to a mess. It was disconnected from the duet control panel and my slicer program. The TC malfunctioned (I am assuming) and the heating element had a meltdown.
(The printer also stopped mid print while the Heater stayed on.)

I am trying to figure out what I need to replace but I am unable to get the duet to connect back to the computer at all.

I saw that these LEDs can help diagnose what the issue is so here is a picture of what lights up when I turn the machine on. (no green LED and the red LED between the usb and reset button isn't on either.)

I am sure I am leaving out a lot of needed info, I just don't know what is needed.

Any help is greatly appreciated.
