Thermal run away Ender 3

I am new to Octoprint and just installed it a few days ago. I'm getting a fault message stating I have no thermal run away protection. As far as I know it is the original system board ( i bought the printer used). M y question is can I just install updated firmware or does the system board need replacing and do I already have the thermistor and its not recognized

thermal run away fault message

What did you already try to solve it

I have done nothing yet hoping to get some guidance here

Have you tried running in safe mode and if so did it solve the issue?

Yes - I recommend installing Marlin, there are example configurations for Ender 3, a very helpful community on the Marlin Discord and across the internet.

Thermal runaway protection is a software feature, if the temperature goes too far off course then the printer will shut down to prevent itself from catching fire. The old ender 3 doesn't have this enabled, which as you might be able to tell is a safety risk. Newer ones do, but you can just update the firmware on your board to enable it.
