Technically, it should have nothing to do with the thermistor. Having said that, there are different models of thermistor with different characteristics all of which can be programmed for in software. The easiest thing would be to find out what the original was, but if you can’t, just change the model being used in the firmware.
I say “just change…the firmware” but I’ve never actually done it myself on a printer 
Hopefully it’s easier said than done. I’m 99% certain that it’s simply a text file where you comment out one thermistor model and removed the comment from the one that you want, but someone else would have to help you with the specifics, if it comes to that.
