I can't even measure resistance and both continuity test as it is loose in clamp near exturuder. Looks physically ok but inside, no connection at all.

Now i already got the rootcause. Resistance tested and thermistor is working fine. Problem is coming from extruder heating wire clamp. I am disappointed with how they loosley clamp the two wires near extruder end. Even i tried to reconnect the wires, the clamper is too bad and cannot make it. Might ...

What is the value for resistance of thermistor in room temp?

i ald check thermistor. It is ok. Even if thermistor is not working, extruder should heat up. Isn't it? I had checked with own thermometer and extruder is not physically heating up.

I am setting up I3 pro B with ramps 1.4 and sometimes having error message " Min Temp " but sometimes, no error. And Nozzle is not heating up but voltage is showing 11.93V on wire. However, heat bed is working fine. Both control from computer and LCD panel have the same nozzle temperature problem. I ...
