I noticed that when I turned the temp control to Max Cold the refrigerator cooled down to "acceptable level". I went to manufacturer website (Frigidaire), to acquire the factory part numbers. Then did a google search using the part numbers which took me to this website.
After reviewing the videos and troubleshooting info on this website, I purchased the Cold Control Unit / Defrost Thermo / Compressor run capacitor. All three "just in case.
Paid extra for the expedited shipment. It arrive on time, and the part was the exact factory replacement. However still came in cheaper than purchasing directly from the Factory and Much cheaper than paying a professional.
Replaced only the Cold Control unit, reset the temp control back to "Mid-Point" (factory setting) and after approx 2 weeks, everything is working as intended. Easy swap, the instructional "How To" made the swap easy. Literally a flat tip screw driver and 1/4 nut driver (as noted in the video)...15 mins labor, done deal. Nice to see a DIY video featuring my exact brand.
