Because of corrosion, the 3 lead thermostat in the “refrigerator side” (right side of attached photo) of my ’01 380 needed to be replaced. The temperature knob would no longer turn. I ordered a new one on line that came with the fan. The problem is, the instructions that came with the 4 lead thermostat states it should be installed in the “freezer side” (left in photo). So ... I’m lost. My refer is wired for the 3 lead in the freezer and the 4 lead in the refer. Is mine wired wrong or...? I ordered by part number, but the one received is not the same. 3 verses 4 lead. Help? *o
