err: mintemp

[rrobertm]

I have a big problem with my printer. It shows next message: "Err: MINTEMP". What should I do, because I cannot set the bed or nozzle temperature manually? It doesn't store tempertature settings. The printer model is I3 pro B.
It doesn't print any job too! Nothing is heating up!

Hi, when LCD is displaying "ERROR MIN TEMP", you can heat up the extruder, please check if you have connected extruder thermistor to correct slot. Please take a photo, let me check for you.

Sorry, I left a word out.
When LCD is displaying "ERROR MIN TEMP", you can not heat up the extruder.
Please show me your wiring.

Fixed err:mintemp, but now I got another problem: the extruder motor is not working. I moved it on x axis motor connector and it works. After that I switced the small motor modules on the mainboard and the one mounted for the extruder motor is not working.

Is the extruder moving with no filament?
