Well if anyone cares, I replaced the main board (that also contains the power supply). Guess What? It still did not work. Everything works but the freezer fan motor. So I took out my new parts, reinstalled her old parts (freezer fan motor kit & main control board) and told her she will have to call Frigidaire factory service because I do not know what else to do. Sometimes I think I should just not repair any newer refrigerators. Who knows what I'll do in the future!
