i have changed the thermistor but it is same again.
could it be a VSSA fuse problem? as i have lower version of duet board and it has no fuse !

i have the first one board which has not fuse for thermistor, bed or fan.

@jay_s_uk
It is a default firmware which i am using from 3D platform to operate the machine.

@droftarts
only fan is working neither the motor nor the heater or thermistor.

@droftarts
okay i will change the thermistor if it can be a problem.

@droftarts

No right now i am using single extruder, actually when i run the command for heating the extruder, it shows the target temp for 2 seconds only then it shows -273 as above.
and when i checked the resistance at the point of thermistor it shows 0 value there.

and yes i downloaded the firmware from 3DP support.

@droftarts
i am not using DWC, right now i am controlling the machine with proterface and Simplify3D.

and iam getting a open circuit error on terminal while i have connected all the things properly.
