# Printer thermistors read completely wrong after changing firmware

(Asked by: username_0 on 2021-03-06)

I recently installed Marlin 1.1.9.1 onto my Creality CR-10S. After doing so, the temperatures for both the bed and hotend now read -14 °C. I have changed the setting in the Marlin `configurations.h` to several different thermistors, and it either reads 0 or -14 °C.

I have now installed several different versions of Marlin and with each one I experience the same problem.

Is there some tuning setting that I am missing or has installing the firmware somehow fried something on my board?
