Age: More than 10 years

My Frigidaire started blinking 4 about a week ago. I noticed that my temperature in both the freezer and the refrigerator was not maintaining. I disconnected the power and plugged it back in, was still blinking 4, still having issues with it maintaining temperature. I read on other forums that it could be a damper issue. We replaced the damper this weekend but still having the same issues. Please help!
