Samsung RF23M8570SR/AA (Rev.5) not cooling reliably

It will cool when you plug it in but after a few hours get error code for compressor and fan, and temperature readings go all wonky and it says the fridge is 20* and the freezer is -10* but it turned off the fan and compressor. Leaning towards control board because it’s unlikely temp sensors go bad in all compartments at once? any tests or help confirming appreciated because it’s just a guess!

I would look for a DC load being at fault.  I think you're loading down.  I've seen a few with a failed fan causing the compressor to stop running.

Thanks I assumed compressor and fan was working because they were running, but now that you mention it, compressor was hotter than normal and fan would change rpm making different sounds so hopefully that’s it! Thanks for the fast response🙏

Update, the eBay seller lost the board and gave my customer a refund so we are ordering another board and waiting on it!
