You have probably damaged the analog to digital converts in the controller... You have probably put 12v on the 5v analog pin.
A thermistor is a variable resistor that changes based on heat. To accurately measure it you need to unplug it.

There is only one ADC in the microcontroller, with a multiplexer to select which input it reads. Over voltage on one input usually wrecks the ADC, not just that input.
Shorts between thermistor and fan or heater connections on the hot end are quite common, so Duet electronics is designed to survive these shorts. See [youtu.be].
