Trying to troubleshoot a cocoon create printer for a friend.

Hey all! I offered to repair a cocoon create "model maker" 3D printer for a friend, and I'm trying to troubleshoot an issue it's having. I think I know what part needs to be replaced, but I'd love a second opinion before buying the parts.

The problem it's experiencing is that when you switch on the printer (at ambient room temperature) the nozzles temperature sensor reads around 75°C and when you try to heat up the hot end it seemingly heats up like normal (climbing one degree every few seconds) before it reaches around 110°C and the machine freezes, becoming unresponsive until it's powered down and powered back up again.

I think that I need to replace the machine's thermistor but I'm not entirely sure. Any help or insite I could get on the issue would be fantastic! Thanks in advance!
