Broken Wire

I have a MK3S

First there was a "Thermal Runaway"

Now I have a "Preheat Error"

Both of which I assume are related to the broken wire in the photo.

What does this wire do and how do I fix it?

Thanks,

Ken

RE:

Heating cartridge and thermistor are very sensitive parts. Switch off the printer before carrying out installation work on the hotend to avoid short circuits.

Have not seen any instructions for installation.

Anybody have any helpful hints?

Is it really as simple as loosening the screw and swapping out the part? Or are there gotchas?
