the freezer was cold and the refrigerator was not! The eavaportor was icing up was not going thun the defrost cycle!

First I unplugged the appliance for safety,then I proceeded to remove the sheetmetal from inside, the freezer compartment, this is where the evaporator is located and where you will find the defrost limit switch or thermostat same thing. also the defrost heater is located here as well. I made note of what plugged into what and what the colors of the wires are for future use. You also need to check the defrost timer which on this unit, it is located in the very front lower left coner of the appliance. Once I received the parts I put things back together in the reverse order, plugged in the appliance and so far so good the refrigerator is cold now.There are a lot of repair manuels out there that will help you repair your appliances and save yourself a lot of money. You just have to be willing to do it yourself.
