Ah nice,
Fairly sure it’s a 100K NTC thermistor which is the same as the rest of the Creality printers. Have you ordered a replacement for it yet? Core Electronics doesn’t provide this particular thermocouple, although there’s plenty online on eBay, Amazon and from Creality directly.

Let us know how you go with the fix. If you find that you still run into that issue after replacing it, you should be able to either reflash the firmware, or replace the main board on your printer if it’s died (upgrading to one of the silent main boards is also a great idea)
