Flashforge Creator pro Tool 1 failure Temperature reads are failing

[jord001]

Hi All, new to the forum and need help. Changed a nozzle in my flashforge creator pro and got a message come up saying Tool 1 failure Temperature reads failing. After a litte research I kept seeing answers saying the thermocoupleer was broken so I changed it. This hasnt fixed the problem and I am hoping someone can guide me in the right direction as to what it could be. thanks regards Jord

Hmm, well if you grip the heatblock at the wrong place when changing the nozzle, you can damage the wires for the heater cartridge and the thermistor.

So change the heater cartridge as well.

thanks for the info I will try that. Im nw to this 3d printing thing so need all the help I can get.

I mean, there are only two things that can go wrong with the hotend, and you've changed one already :-)
So odds are good it's the other one.
