Upgraded to an E3D and now nothing works the same.

It won't let you extrude if it thinks the extruder temperature is that cold.

I'd have to go look in the firmware (and I am lazy) but the minimum extrusion temp is around 179 if my memory is not too faulty. That may not be exact, but it is close (and a lot hotter than yours is reading)

 

That is a weird value for a shorted thermistor (they usually read closer to zero) and an open one will read stupid high, BUT... if it reads that all the time (and the extruder is working) then yep--it is broke. Good news is they're cheap, better news is that @Printed Solid has some that thread in with a metal case to make them less likely to break.

 

Of course, if your printer is still under warranty you can use the tech support form on the main page to request a replacement, but be warned... that takes longer than just ordering one (and, like I said, they are cheap).
