This model is double evaporator and the part of the refrigerator freezes, which in turn stops cooling, because there is no dew point. Someone help me with the card diagram. Check all the sensors and they all measure between 4.2 and 4.6 Kohms, the resistance of the freezer if it heats, but you would need the diagram to verify how to activate the 3-way valve, I think the problem is there, because the freezer is working properly. The 2 fans also work well. In advance, thank you very much for your valuable support. Atte Jose Hernandez
