Hi people, I have a problem with an old Amana garage refrigerator. It's been working fine over the years but I plugged it in a few days ago and have the following problem. Although the freezer gets cold (0 degree), the refrigerator area seems to only get down to 48-50 degrees. I cleaned the bottom condenser coils at front and vent opening at rear bottom. I have taken the back panel of freezer compatrment off. The evaporator coil has no ice at all. I'm thinking some sort of cold control. What do you all think? Open to suggestions. The fridge is very old so I don't know what parts would be available. Not even sure where to find it or how to test. Again, thanks for any guidance on this. This is clearly the best DIY site on the internet.
