After replacing these items the temps remain the same -5 in the freezer and 28-30 in the refrigerator. The temp is on the lowest setting, what's next? Called a local repair guy and he really didn't want to look into it, as the time troubleshoot and then wait for the cooling to take place is too long.

All that's left is the upper board, the heating unit, and cooling unit.
