ok, the welds are not spread over the entire pellet. But I checked for continuity.

Unfortunately I think it could still be soldering related. I can't tell for sure in the photo:

but it looks like some of the pins are still a little cold and under-soldered and not wetted out enough onto the pads.

Thank you very much I redid (well) the welds. I have the temperature displayed!

Thank you very much for your help! I don't know how to thank you

No worries. Glad that got it working. Good job sticking with it until it was fixed. Have fun!
