Looking for guidance or confirmation on how best to proceed.
Some background: About 1-1.5 years ago, my front door panel UI stopped working and it displayed: Er CE
By not working, I mean that it would not dispense water, ice, but it still allowed me to set temp. Everything else with the refrigerator still worked fine, I just had to get ice from the maker myself. Fridge, middle drawer, and freezer drawer all cooled fine. The middle drawer UI panel was blinking and was non responsive but remained as a freezer and continued to work.
My understanding was that this is a failure for the UI board to communicate with the control board. I purchased a new Control board and an used UI board, swapped out the control board first, and still got the Er CE. Then swapped out the UI panel and still got the Er CE. I just parked trying to repair it, as life got busy with covid and other things.
Fast forward to this weekend, when we opened the fridge door and all of a sudden the led lights went out. At the same time, the front panel UI constantly displayed all lights/indicators at once and was non-responsive. I swapped out the control and UI boards as I had the other set, and the UI was back to Er CE but the led lights in the fridge did not come back on. We then noticed that the compressor was not running, although the condenser and inside fans were running. It is not cooling given the compressor is not running.
At this point, I went back to the control board to take some voltage measurements at the harnesses. Control board had 120VAC and 12VDC supply. There was 0VDC going to the inverter, the 120VAC supply to the inverter was fine. Inverter was flashing green, twice every 5 secs, which indicates a communication error. I also confirmed the 0VDC to the LEDs with doors open. I confirmed that the door switches operate and all the fans have 12VDC. This is obviously pointing me back to the control board, but I am puzzled how both control boards have failed. Everything is hooked up properly, as I have the data sheet and also took pictures before I did anything. My suspicion is that the UI board that was all lit up took out the control board. I suspect I replaced the control board first, and not both the control and UI board at the same time.
I presume my next step should be to purchase and swap out the Control board and go from there. My concern is whatever damaged the 2nd control board may occur again for the new one, should it not have been the bad UI board. Is there any checks or precautions I can take?
Any other guidance?
Thanks for reading!

I did spend a few hours messing around with positioning the wires and zip tying them in a position with connectivity, but every time the door is opened all the way and then closed, I would loose connectivity.
