Hot end thermistor failed, getting "def" reading

[Culyx]

From other threads I decided to check on the thermistor more closely, I think I may have damaged it while trying to tighten the hot end to prevent PLA from leaking around the nozzle.

I've seen a few options listed for fixing/upgrading the thermistor but I can't seem to narrow down any "how to" guides on upgrading or replacing it, I've seen the words "heater cartridge" and "screw in" used are these better options for replacements?

Is the heater cartridge a temperature reading sensor? The name makes me think it actually heats things

Would this be a good replacement for the thermistor? I'm troubled by the lack of clear specifications on things like measurements and part compatibility, though I understand the reasons behind them.

I just used the ebay source that GeneB links to in his how to video and its all good there is an amazon option that looks to be selling the same stuff (at a higher cost of course)

that you link to is the same item
and the heater

Cool, thanks for the confirmation. I may update the heaters at some point but those aren't giving me any grief at the moment. Just going to start with the thermistor and get that working again.

Thanks again for the advice!
