-14 Temperature Reading

Hi everyone, was changing the nozzle on my printer which I have done many times before and out of nowhere it started beeping. When it stopped i noticed the temp reading was at -14 and whenever i tried heating the nozzle up it beeped and reset

Hello Gargled Milk

It’s Very possible that you now have a Broken or disconnected Wire on your Thermistor
It’s the x2 smaller white wires on that hotend

Yes those wires are crazy easy to break.

Yes for certain. When you get it replaced my advise it keep the wires contained. I know the resistive wires shouldn’t really be close to heat cart wires but personally I do that anyway so I am less likely of breaking them when I change nozzles.

Luckily the thermistors are about $5, easy fix, I agree though, its prolly just a broken wire.
