Please post your problem in a the correct sub forum

I’ve moved your topic to the correct section.

It seems like the left one isn’t connected correctly.
Check if the cable is working properly, measure the resistance of the same wire from printhead to the motherboard.

The right one is indication 25degrees so that’s good.
