A10m -14C hotend

Post by Cg83 » Sat Nov 16, 2019 8:54 am

I had a clogged extruder that required disassembly to clear. Upon reassembly the LCD showed a nozzle temp of 3**°C (pretty sure it was 358 but I could look again). Upon disconnection of the hot end from main board it shows a temperature of -14°C and will not heat the hot end. To my knowledge this means that it is not the main board.
This would place the problem in; board that rides with the extruder (is the correct name the ramps board?), the thermistor, or the wiring correct?

How would I go about troubleshooting what part in specific is bad?

 reading MAX temp means you shorted it.
marlin is programed to prevent use in both these cases.
replacing the thermistor seems the best action there like 1$ all day on amazon.
something like this? looks like the right plug and all, just cut to length and resolder wires?
