Hi~
I think you should test about A0,A1.
First, J27 and J28 are connect 1 and 2 with each other.
If Analog signal is correct operation at this situation, U8 seems to be dead.

Thanks.
If I put J27 and J28 in the opposite position, trimmer and temp level are shown correctly.
Thus AD-Converter works, but U8 is dead

Unfortunately, you should be change an U8.
The Part name of U8 is LM358APWR(Dual Operational Amplifiers)
