While it is dis-connected check all the plug ins very carefully, make sure nothing is loose at the circuit board. Hook up the DC supply and plug back in and see if it cleared. IF not then it could be the circuit board and I would have it looked at under warranty, it should have a two year warranty. If you start taking to many items apart you could void that warranty, have seen that happen before. Sometimes the code will reset if you take away the DC power, that is all the fridge needs to turn on"

Make sure thermistor is clear so air gets around it. Should be mounted to fins if refer portion.
