Hi my name is Robert.....

What I would do is hook up another DC supply directly and see what happens, sometimes a power converter can put out dirty voltage or AC ripple and the board does not like it at all, so that would eliminate a DC issue, all the fridge needs to turn on is DC power. I would also unplug the AC cord or try an outside source and see if that makes a difference. Did you replace BOTH the upper display panel and the lower circuit board on the back of the fridge????

OK....

No help I am trying to help you out now, it takes some going back and forth to figure out the issue!!!!

IS the display panel shutting down meaning there is nothing on at all on the display???

IF the display panel is going dead go to the flue canister and look for a high limit, it would be a small round disc and in the center is a tiny button, when the high limit trips it cuts power to the fridge. IT would be smaller wires then the AC heating element..... Robert

Beyond that you have a bad wire harness from the lower circuit board to the upper display panel.
